Homemade equipment: how to make a mini tractor with your own hands. Do-it-yourself tractor: how to make homemade mini tractors at home, how to assemble and build a manual one - drawings and dimensions Homemade mini tractors for the household

03.01.2022

Agricultural walk-behind tractors have one serious drawback - the operator has to walk along the cultivated area with them. As a result, fatigue sets in quite quickly, and the time it takes to complete work increases, which leads to a sharp decrease in the efficiency of labor costs. Another thing is a mini-tractor, which has a full wheelbase and steering. But not everyone can afford to buy such equipment. Therefore, in the agricultural environment, you can increasingly find homemade mini tractors, which are designed on the basis of professional or semi-professional walk-behind tractors.

Converting a walk-behind tractor into a mini tractor: main points

Unlike amateur equipment, professional and semi-professional equipment has more power. For example, from a walk-behind tractor with diesel engine at 9 hp you can make a pretty decent mini-tractor for plowing and cultivating. Ultimately, it all depends on the goals that the owner of the modified equipment intends to achieve.

Designing and assembling a homemade mini tractor is not an easy task, but it is doable. And to solve it successfully, you need to focus on two points:

Development of a body and frame, as well as a diagram of their connection with the base of a mini-tractor - a walk-behind tractor.
Development of a kinematic scheme.

The homemade frame and body are made from metal corners or profiled pipes. When calculating the structure, it is necessary to take into account the ratio of its weight to the power of the motor, as well as the resistance that the machine will overcome when performing various types of work.

If you choose a powerful walk-behind tractor as the basis for a homemade mini tractor, this allows you to use ready-made car or motorcycle trailers. Moreover, leading manufacturers of walk-behind tractors have long provided for the design possibility of connecting such trailers to their manufactured equipment.

The kinematic diagram of a homemade mini-tractor is a set of design solutions that ensure the transmission of torque from the walk-behind tractor engine to the drive (mainly rear) wheels. When calculating, it is necessary to distribute the load on the drive axle evenly - both reliability and durability, as well as functionality, that is, the possibility of using the equipment, directly depend on this.

DIY mini tractor: where to start?

In fact, there are many options for constructing a mini tractor yourself. However, the principles used are approximately the same everywhere:

turns towards the operator and is fixed on the frame.
Control is realized using steering rods.
Hydraulic is used drum brake.
The brake and clutch are pedal controlled.
Manual control is used for the accelerator and attachments.
The operator's seat is located above the rear drive axle.

One of the most simple ways To create a mini tractor with your own hands is to purchase an adapter - a two-wheeled cart with a seat for the operator and an aggregate system (for installing attachments).

Obviously, to assemble a mini tractor you will need various spare parts. They can be easily found among automobile ones. For example, drum brakes for drive wheels, steering rack and pedal control units can be taken from passenger car VAZ. In the same way - by searching the auto parts market - a seat and other structural parts for a homemade mini-tractor are selected.

But in addition to spare parts, you must also have a whole arsenal of tools on hand - a welding machine, a drill, a circular saw, spanners etc. And it is very desirable that during the process of assembling a mini tractor you have access to a specially equipped workshop or, if necessary, you can use the services of specialists in welding, milling, plumbing and auto repair.

Mini tractor frame

The chassis is the basis of a mini tractor. Its main quality should be reliability, but you need to carefully monitor the total weight of the structure in order to ensure normal adhesion of the wheelbase to the soil when performing work and at the same time not to overload the engine.

To make the frame of a homemade mini tractor of medium power, a lightweight channel, profiled pipe or metal corner is suitable. The dimensions of the structure, the assembly of which is carried out by welding, must correspond to the dimensions of the machine. It is necessary to make holes along the contour of the frame for hanging and securing the structural elements of the mini tractor.

The ratio of the weight of the frame and its strength must be optimal. You should not overload the structure with additional stiffening ribs, nor should you skimp on metal, sacrificing overall reliability indicators.

Before you begin assembling the frame, you need to decide which trailers you are going to use when working with it. And in order not to lose thought during the design process, before starting work you should complete the drawings future car and its main components with main dimensions. To do this, you can use ready-made documentation, which needs to be adapted to the specific parameters of your mini tractor.

Front and rear axles

These units are created from individual spare parts and units removed from cars or even trucks or other agricultural equipment. However, you will have to do some details, as well as the assembly itself, yourself.

To make a front axle, you will need:

cross beam;
bushings for supporting rotary axles;
axle bushings;
the axles of the wheels;
(ball and roller);
bolted connections.

A piece of profiled pipe or metal corner will do the job perfectly as a cross beam. For the manufacture of axle shaft bushings, structural steel 45 is suitable. The rotating support bushings are made of profiled pipe, modified for the installation of bearings, and are closed with steel covers made of steel grade St3. The front axle assembly, consisting of a cylindrical race and roller bearings, is welded in the center of the cross member. Using large bolts, the bridge must be secured to the bushings in the cross member of the frame.

The tightening force of bolt connections is responsible for the amount of play of the front axle relative to the design of the mini tractor. Too tight, as well as too loose fastening has a negative impact on driving comfort, so the play must be optimal.

Assemblies are performed in the same way rear axle. The finished design can be borrowed, say, from a UAZ car. The long stocking of such a bridge will need to be shortened so that standard short axle shafts can be used. It wouldn’t hurt to protect the rear axle, or rather its welded joints, from possible impacts during operation. For this purpose, a support is used - a metal corner placed along the welds of the prefabricated bridge structure.

Wheelbase and kinematic diagram

The choice of wheels for a homemade mini tractor deserves special attention. It is quite possible to use wheels from a passenger car, but the dimensions must be observed here. Optimal dimensions rims for are 12-14 inches. When choosing a smaller diameter, there is a risk that the machine will bury its nose into the ground during operation. On the other hand, if the front wheels are too large, the operator will have to exert considerable effort to perform maneuvers. However, to facilitate the process of driving a car, you can always use the power steering from a passenger car or other agricultural equipment.

Mini tractor wheel tires must have developed lugs. This will increase the maneuverability of the machine, reduce the load on chassis and will facilitate the management process.

As for the kinematic scheme, it is better to use ready-made options, the search for which currently does not take much effort. The diagram must be adapted to the parameters of the components that you are going to use to create a mini tractor. It would be useful to consider the possibility of connecting attachments, which will greatly increase the functionality of a homemade machine.

Control system and operator seat

After manufacturing and installing the chassis, you can begin to implement the kinematic diagram and install the control system. The most important thing in this matter is to place it correctly. The front seat of a passenger car, which is easy to find at car services and in workshops that dismantle vehicles, will do an excellent job of this role.

The steering wheel should be set at the optimal height for the operator. The steering wheel should not interfere with the free placement of the knees - it must be mounted so that working with it in a sitting position does not cause discomfort.

All the necessary parts for pedal, manual and lever control of the machine and its functional units can be found in the same place as the seat and all other spare parts - in workshops or on the market.

Engine installation and body arrangement

After assembling the chassis, implementing the kinematic diagram and installing the operator's seat with the control system, you can begin installing the main unit of the minitractor - the engine. To securely fix it on the frame, you should use a special plate with grooves - it will also give the chassis additional rigidity. Next, you need to lay out the electrical and mechanical circuits of the control system, connect and configure the operation of the control system.

The body trim is carried out at the user's request, however, it is still better to cover some components and structural elements. This will prevent their contamination and failure in case of contact with foreign objects and soil.

Most people associate work in agriculture with cultivating land. But in order to sow and grow crops, berries and vegetables, as well as fruits, it is necessary to plow the soil, supplement it with fertilizers and provide watering, as well as weeding. If the farmer has specialized equipment, the work can be greatly simplified. Such equipment is small in size, but copes with basic tasks quite successfully. Among them are:

loosening;
plowing the land;
mowing grass.

Firms and large agricultural complexes approach solving this issue using domestic and imported models. If you are the owner of a private farm, you may be limited in your financial capabilities. In this case, you will have to use a mini-tractor, possibly made independently.

This will save money, but you should be prepared for the fact that assembling such equipment is accompanied by certain difficulties. This does not stop many, because every farmer has the power to make such a mini-tractor on his own, additionally equipping it with equipment to solve a wide range of problems.

The main types of homemade tractors

A farm tractor can belong to one of several varieties, including:

multifunctional equipment;
homemade tractors with the function of collecting garbage and mowing grass;
riders.

The first type is equipment with which you can cultivate the soil, remove debris, and also cut grass. Homemade tractors are usually equipped with medium-power power units. Multifunctional equipment can cope with an area of 6 hectares. If necessary, you can install it on it attachments, thanks to which the list of tasks expands.

Homemade tractors on wheels can be designed to perform a narrow range of tasks; they are used to cultivate an area of up to 2 hectares or create lawns. Riders are necessary for applying fertilizers, as well as treating with pesticides. They can use the equipment to perform other tasks when there is a need to cultivate a small plot of land.

Tractor manufacturing features

If you decide to do homemade tractor with your own hands, then at the first stage you will need to make a frame for which a rolled channel is used. The design contains traverses, and they should be located at the back and front. In addition, the system has side members. When the frame is created, the width of the front part is slightly reduced, which gives the part a trapezoidal shape. A hole must be created in the frame, thanks to which other devices and elements can be strengthened.

Work methodology

When making a homemade tractor with your own hands, it is necessary to use racks that must be welded to the corners. They will serve as a subframe. They should be additionally connected at the top. You need to install the rear axle on the frame.

Sometimes a project involves assembling a four-wheel drive tractor, in which case the front axle must be located on the frame. A homemade tractor is made with your own hands using an engine. The most suitable option would be a motorcycle engine. To mount the gearbox on the frame, you need to find a place. The box should be positioned so that it is more convenient for the driver to control it.

Now you can begin installing the steering components. A steering wheel is usually used for this. This part is usually borrowed from a car model domestic car. In some cases, a motorcycle handlebar is used. A trailer will need a tow bar. It is installed at the next stage, welded to the frame. When making a homemade tractor with your own hands, you need brake system and tank, which must proceed to the electrical connection.

Assembly instructions: frame

A homemade tractor may seem disproportionate and unsightly. In fact, if the mechanism is assembled correctly and all the key components are arranged rationally, then the system will work properly, performing all the tasks assigned to it. As additional elements traverses protrude from the frame.

The spar is assembled from successive stages, the inner ones consisting of a square steel pipe, while the outer ones are made of a channel. The front traverse should be smaller than the rear. This indicates that a 12-gauge channel will fit the front crossmember, while a 16-gauge channel will fit the rear.

Powertrain, axle and track

Before you make a tractor, you must select a motor of the required power and torque. Sometimes a four-cylinder diesel engine with a power of 40 hp is used for this. With. This unit is water cooled. As for the bridge, it can be installed without additional adjustments. It can be borrowed from a domestic truck and integrated into homemade equipment.

Before you make a tractor, you must take care of the presence of a caterpillar. The most simple option is a design with rollers made of tires and wheels. They can be taken from carts. Taking into account the size of the tractor, you should select the dimensions of the wheels. The caterpillar can be made from a large tire, which is pre-cut on the sides.

Additional equipment of the tractor with an engine

A homemade tractor with a VAZ engine can be found quite often, as well as installations of the following types:

M-67;
UD-2;
MT-9;
UD-4.

You can equip the tractor with an engine from a Moskvich or Zhiguli car. When it is intended to make a homemade product according to the 4x4 formula, for the M-67 the transmission gear ratio is increased. Otherwise power point will lack power to provide force to the wheelsets. It must be taken into account that the power unit may require an additional cooling system.

Additional transmission information

A homemade tractor with a VAZ engine can be supplemented with a power take-off shaft and gearbox, which should be borrowed from the GAZ-53 car. The clutch can be taken from GAZ-52. These nodes cannot be used in finished form. Adjustments must be made.

In order to synchronize the engine with the clutch, you need to prepare a new clutch basket, adjusting it to the dimensions. The rear plane of the engine flywheel is shortened, and an additional hole is drilled in the center. These manipulations can be performed on lathe.

What else you need to know about the rear axle and wheels

A mini-tractor for snow removal can be equipped with a rear axle from a truck or car. The axle shafts are pre-shortened on a lathe. If a finished bridge cannot be found, then a design from different cars. Experts recommend using any unit that fits in size, because the front axle does not act as a drive axle.

Wheels should be selected according to their radius. If the equipment is intended to be used for transporting goods, then it is better to choose disks whose diameter varies from 13 to 16 inches. For equipment that will be used for agricultural work, you can use wheels with a radius ranging from 18 to 24 inches.

Equipment for a homemade tractor

The described equipment includes a frame for a homemade tractor. After assembly, it is necessary to install the drive wheels and road wheels. Power unit is mounted at the next stage, then comes the turn of the gearbox. The differentials and onboard brakes should be installed in the next step, after which all components can be connected to the gearbox.

The next step will be assembling the controls, as well as arranging the workplace. Additional parts and tracks can be installed in the next step. Now the master will have to check the performance of the tractor, modifying its individual components, if necessary.

Conclusion

A mini-tractor for snow removal will also show its abilities when cultivating the soil. However, in order to achieve two thousand engine revolutions at a speed of 3 km/h, you need to adjust the transmission. Each wheel of the rear axle should ideally be equipped with a separate gearbox.

The advantages of homemade tractors are obvious. Each person can make them independently, the cost of parts for such devices is lower than for factory ones, they do an excellent job of cultivating small areas of land. In addition, many parts for a homemade tractor can be found on your farm.

Let's take a closer look at the question of how to make a tractor with your own hands.

1 Preparation of drawings

Despite the fact that any tractor, be it a standard size or a motorized tractor, consists of at least hundreds, or even thousands of parts, anyone who can master the diagram depicted in the form of a simple drawing can assemble it independently. Thanks to the schematic drawing, assembling a tractor with your own hands is similar to a standard construction kit, where element A is connected to element B, then part AB to element C, and so on along the chain.

Although, it is worth noting that in our country there are probably enough self-taught craftsmen who can “keep a drawing in their head,” that is, perform the same sequential actions as with a drawing, only follow imaginary instructions. However, this does not apply to everyone. Anyone who does not have such experience is unlikely to be able to assemble any structure without turning to a pre-drawn diagram for help.

In case you had a “bad relationship” with drawing at school and you are not able to organize a drawing of a diagram of a full-fledged homemade tractor, ask acquaintances, friends or relatives who understand this matter better than you about it. As a last resort, Google search will help you find any information.

Before you start drawing the diagram yourself, decide what kind of tractor you want to make, on what basis it will be made. So, for example, homemade tractors can be:

tracked;
wheeled.

They are manufactured on the basis of:

walk-behind tractors. The tractor from Niva is very popular in Russia (one of the most famous walk-behind tractors in the Russian Federation);
automobile engines. Moreover, engines of both passenger cars and trucks and cargo-passenger vehicles can be used. By the way, the GAZ-66 engine is very suitable for making a homemade tractor with your own hands, which will have high power. You can often find a tractor from an UAZ;
UD-2 is a universal engine used as an additional motor in installations that are equipped with an electric generator, as well as as an engine in a homemade tractor;
The homemade 4×4 tractor is popular among people. A homemade 4x4 tractor is also called a fracture.

Having decided on the above question, you can safely proceed to the drawings. In this case, after creating the diagram, be sure to make a list of available parts and assemblies, and a list of those elements that need to be purchased, after which, buy the missing spare parts. Only after the entire list of parts is in your garage can you begin assembling the structure.

1.1 Design features

How to assemble a tractor with your own hands? There is no big difficulty in this. If you have correctly drawn the diagram and prepared all the necessary parts, making a tractor with your own hands proceeds to the practical part. The difference in modifications and options depends on the tools and skills you have. Below we describe the most optimal design:

If you have chosen to make a caterpillar tractor with your own hands, because during operation it does not damage the top fertile layer of soil, to simplify it, buy a new module equipped with wheels and a seat. Alternatively, all the elements can be assembled yourself at home. However, such a design will lack a drive. The assembled, crawler tractor is controlled with your own hands by turning the transmission-motor unit. For this purpose, it is recommended to use a standard steering wheel.

The walk-behind tractor should be supplemented with a hinged module with a seat; for earthworks, it is also necessary to take care of the hitch. To implement this option, assemble a frame using a wheelset and rolled metal. Then install two trailer units and a seat on it. Do not equip wheels with shock absorbers, this will negatively affect the speed of the device.

2 Tractor assembly

There is no single recommendation on what to take as a basis for the future unit and how to make a homemade tractor, which is influenced by the presence of this or that equipment on your farm from which the homemade product will be constructed. Therefore, it is advisable to consider various options. If you don’t have a walk-behind tractor made on the basis of a Zhiguli, the tractor will become a much better assistant.

2.1 Tractor based on Zhiguli

To build a Zhiguli tractor with your own hands, first of all develop a kinetic diagram that takes into account the balance of the structure. The device will include: engine, rear and front axles, reverse gear, cardan transmission. The engine will drive the front wheels. Through the chain, torque will be transmitted sequentially to the gearbox, cardan drive, etc. Presenters rear wheels, as a result, will rotate.

The frame is made of pipes and angles. Make sure the fork and bushing are positioned correctly to allow the trailer to turn. The body is made from sheet metal. The height of the sides should not exceed 30 cm. Next, the attachments are mounted and driver's seat. Then check the functionality of your unit. The final step is to prime and paint the surface of the metal elements.

2.2 Tractor with D-21 engine

Many craftsmen prefer to equip a homemade tractor with a Chinese engine. Lifan, Forza, Zonshen are taken as a basis. However, experienced designers recommend setting reliable motor UD-2 or D-21. In the first case, the engine develops power up to 8 hp, in the second – up to 25 hp. Together with the 4-stroke system and air cooled Such equipment is not only successfully used for agricultural activities, but also for transporting goods. Let's consider the option with the D-21 diesel engine.

To create the frame, take a pipe from a haystack. Pre-cut the half-frame borrowed from the T-25, weld a pipe to its front part, and a metal sheet of 3.5x50x50 cm to the rear part. A hydraulic tank and a hitch with a hydraulic cylinder, which is also taken from the T-25, are attached to the sheet using bolts. It is better to purchase a factory-made front axle, otherwise problems with the axle shafts may arise. Wheel disks take from GAZ-52, tires from Belarus 82 (8.3×20), which are manufactured by the Minsk Tractor Plant.

The front wheels on a homemade tractor with a D-21 engine are from the T-25 (6.00-16). The hood and beam are original, but the fuel tank needs some work. To do this, weld a 40-liter container from 3 mm sheet. Place the finished product on back tractor under the seat. Carve an adapter plate for the GAZ-52 gearbox. The clutch used is a basket, a fork and a release bearing from the Yenisei combine. First remove half of the springs. The disc included in the clutch is suitable for any (from both GAZ and UAZ).

Grind under the basket in the flywheel seat 3 mm. Primary shaft The gearbox must be lengthened by 12.5 cm, the cardan drive from the GAZ-52 must be shortened. The connection must be removable. Get the steering column from GAZ-52. Hydraulics for a homemade tractor are assembled from an R-80 hydraulic distributor with a floating effect and an NSh-10 pump. It is placed through a fork connection at the front of the engine. Pre-replace standard bolt, responsible for fastening the motor pulley.

You should not install the pump on the gearbox through the power take-off, because when the clutch is released, the hydraulic system will turn off and the rotation speed will be unsatisfactory.

2.3 Tractor based on Oka

Do-it-yourself tractors from Oka follow the same principle as those from others Soviet cars. It all starts with the construction of the frame. Stock up on sheet iron and metal channel beams.

The design is a standard rectangular shape welded from metal corners. The front and rear axles are assembled from Oka components. The device is equipped with an Oka engine. However, before installing the engine, the wheel clearance is increased to improve cross-country ability.

The rear and front side members are strengthened as they bear the brunt of the load. A coupling mechanism should be provided for mounting attachments. Drawings for further assembly can be found on the Internet. If you don’t have the specified car, you don’t have to buy a new one vehicle, the unit is also suitable in a non-working state, since its individual elements are used.

2.4 Review of a homemade mini tractor (video)

Homemade mini tractors are ideal for cultivating small plots of land. Almost anyone who has at least a little knowledge of technology can assemble a mini tractor with their own hands.

In terms of technical characteristics, homemade products are significantly inferior to factory models. But using a powerful tractor on small areas is at least not rational. Even the costs of maintenance and fuel and lubricants will not be justified. And here small tractor, assembled with your own hands, turns out to be very appropriate. In this article we will tell you how to make a mini tractor at home.

Advantages and disadvantages of homemade mini tractors

A mini-tractor made by yourself is much cheaper than factory models, and in terms of functionality it can sometimes give a head start to more powerful tractors. The homemade product can be used in vegetable gardens and orchards, for cultivating crop areas (not exceeding 10 hectares), transporting small-sized cargo and harvesting work.

The cost of such a machine pays for itself in just one season., because the main components and mechanisms are usually removed from broken equipment or purchased at bargain prices. Some farmers convert other equipment into a mini-tractor. In this case, the process of manufacturing equipment is greatly simplified.

Among the disadvantages, one can note the difficulty in selecting suitable parts. In addition, if some components fail, problems with replacement or repair may arise. After all, whatever one may say, the tractor is assembled from junk, so some parts cannot be found.

To prepare drawings, you must have technical skills and knowledge. After all, a mini-tractor must work with mounted and trailed equipment, for this it is necessary to calculate the traction force of the engine.

Advice! A mini-tractor assembled with your own hands must be registered with the traffic police. Otherwise, when you go out on the road, your homemade product may end up in a parking lot, and you will be fined.

We prepare drawings

Some craftsmen are able to assemble any equipment with only a bunch of old hardware and a general work plan that is kept in their heads. There are only a few such people, and if you are not one of them, you must first prepare drawings of the main components of the future machine.

If you do not have the necessary knowledge, you can ask friends or acquaintances to make drawings. Finally, the necessary information can be found on the Internet.

Having the drawings at hand, assembling a mini-tractor at home will resemble a children's construction set. That is, you take part A and connect it to coupling B.

It is worth noting that some components and parts that will make up the homemade product may require adjustment or additional processing. Agree, explaining to a turner or welder what is required of them is much more convenient not with their fingers, but with a ready-made project and drawings at hand.

By the way, at this stage, you need to decide what kind of mini-tractor you want to make with your own hands. 4x4 breaking is very popular among farmers. This is a small model on an articulated (breakable) frame, with four-wheel drive. This homemade product is optimal for working on farms.

How to assemble a mini-tractor with your own hands

Having prepared diagrams and drawings, you need to find suitable parts. At a minimum, you will need an engine, transmission, frame and steering. Finding the necessary parts at home is very problematic, so you can stroll through the flea markets and look through websites selling spare parts. Here you can literally buy the parts you need for pennies.

Frame

The fracture is usually made from metal channel No. 5 or No. 9. The structure of this material has a sufficient margin of bending strength. Two half-frames are welded from the channel, which are connected to each other by a hinge joint. For these purposes, you can use driveshafts from trucks.

If the fracture does not suit you, you can make a mini-tractor on an all-metal frame. This design usually consists of four elements: right and left side members, front and rear crossmembers.

The spars can be made from channel No. 10, the rear and front traverses from channels No. 16 and No. 12, respectively. A metal beam can be used as a cross beam.

Engine

Transmission

For work, a mini-tractor made by yourself can be equipped with any engine of suitable power. The best option is a power plant with a power of 40 horsepower..

Most often, M-67, MT-9, UD-2 and UD-4 engines are installed on homemade units. There are models equipped with an engine from domestic passenger cars of the Zhiguli or Moskvich series.

If the homemade product is manufactured according to the 4x4 formula, the M-67 unit will need to increase the transmission gear ratio, otherwise the power plant will not have enough power to provide the necessary force for the wheelsets. Please note that the power unit may require an additional cooling system.

Transmission

The gearbox and power take-off shaft can be removed from the GAZ-53. The clutch will fit from an old GAZ-52. These units will not fit in their finished form; additional adjustment will be required.

To synchronize the clutch with the engine, you will need to weld a new clutch basket and adjust it to the required dimensions. The rear plane of the engine flywheel will need to be shortened and an additional hole drilled in the center. These operations can be done on a lathe.

Steering

This unit should include hydraulic cylinders, this will provide the mini-tractor with better controllability. It is impossible to make a hydraulic system with your own hands at home. Therefore, it is necessary to remove the ready-made hydraulic system from any agricultural machinery. Please note that you will need a pump to circulate oil in the hydraulics.

Rear axle

You can take a suitable unit from a car or truck and install it on homemade design. You must first shorten the axle shafts on a lathe.

If there is no ready-made bridge, a composite structure from different machines is allowed. The front axle is not driven, so any unit of suitable size will do.

Wheels

The radius of the wheels depends on how the mini-tractor will be used. For transporting goods, discs with a radius of 13 to 16 inches are better suited. To perform agricultural work you will need wheels with a radius of 18-24.

A mini-tractor made by yourself should produce about 2,000 engine revolutions when plowing, at a speed of 3 km/h. To achieve such indicators, it is necessary to adjust the transmission circuit.

Ideally, each wheel of the driving rear axle should be equipped with a separate gearbox. In this case, the rotation is set by a four-section hydraulic distributor.

With this steering scheme, there is no need for a driveshaft and rear axle differential. Hydraulics will control the wheels. Necessary equipment(pump and hydraulic cylinder) can be borrowed from the MTZ-80 tractor.

As you can see, making a mini tractor with your own hands is not at all difficult. Despite the fact that this is a rather labor-intensive process, the result will more than cover all the effort expended. Moreover, assembling a homemade structure is a very exciting activity.

The presence of a piece of land imposes on its owner the responsibility to provide care for it. And one of the urgent problems that must be solved is soil cultivation. Such work can be done manually if the area of the site is no more than 10 acres, and even then this is already problematic.

For territory large sizes you can use a homemade mini tractor, which is an ideal option. At the same time, it is not necessary to purchase a mini-tractor from an official distributor or from a factory, because such equipment can be assembled with your own hands; it is enough to have at least minimal knowledge of technology.

If we compare homemade cars with factory software technical specifications, then superiority will be on the side of the latter. However, it is still wrong to use new technology to cultivate small areas of land. Moreover, this is due not only to the high costs associated with maintenance and acquisition fuels and lubricants. This technique can cause serious damage to the soil structure. Therefore, a homemade mini-tractor is a much more preferable alternative. Next we will talk about how to assemble a mini-tractor at home.

Advantages and disadvantages of homemade mini tractors

If you need equipment for cultivating a plot of land, then Don’t immediately discard the idea of creating a mini-tractor with your own hands. In addition to the fact that you can save a lot of money, you will have the opportunity to make a machine that can demonstrate much greater functionality than tractors with more power. A homemade mini-tractor can become your faithful assistant, which can be used for plowing vegetable gardens and planting orchards, as well as cultivating crop areas, transporting small-sized cargo and harvesting crops.

A the cost of producing such equipment is so low, that one season of its operation is enough to cover all costs. The fact is that for the manufacture of such a tractor, components and mechanisms that can be borrowed from broken equipment or bought at bargain prices are suitable. Some owners often show resourcefulness in this matter, and, taking other equipment as a basis, make certain changes to it, as a result of which they get a homemade mini-tractor. Naturally, in this case you will have to perform even fewer operations to assemble the mini-tractor.

Is it true, there are some disadvantages here that need to be mentioned. To make a mini tractor you will need certain parts that may not be so easy to find. Difficulties can also be encountered when certain mechanisms fail, and it is unknown whether it will be possible to find an equivalent replacement for them. It must be remembered that to assemble such equipment, components and mechanisms are used that are borrowed from equipment that has not been produced for a long time. Therefore, it is possible that certain details will not be found.

An important stage in the manufacture of a homemade mini-tractor is drawing up a drawing. To do everything right, you cannot do without technical skills and knowledge. You also need to take into account that the mini-tractor will be used with mounted and trailed equipment, and therefore the owner will have to calculate the traction force of the engine.

Drawing up drawings

Usually, When a person has a desire to assemble some kind of homemade equipment, it all starts with an idea. Some people can do without a work plan presented on paper, relying on their own technical knowledge. However, not everyone is such a master, so it would be better if you start the process of assembling a homemade mini-tractor by preparing a drawing of the main components.

If you find it difficult to solve this problem, you can turn to your friends if they have already done something similar. As a last resort, you can use the Internet and try to find the necessary information there.

After you receive the finished drawing, you can easily assemble a mini tractor. It will be no more difficult than playing with children's construction sets. Schematically, the work will look like this: you will need to take part A and connect it to part B.

Keep in mind that certain components and mechanisms will have to be pre-prepared before assembling the tractor. Keeping in mind that you borrowed them from other equipment, most likely their sizes and other characteristics will differ from those required. But, having a ready-made drawing in hand, you can easily modify all the mechanisms, because you will clearly know what they should be like.

In the process of drawing up the drawing, it is important to decide what design the mini-tractor should have. Quite often farmers choose the 4 x 4 breaking option.

We are talking about a version of the tractor that uses an articulated frame, complemented by a 4-wheel drive. This type of equipment will be an excellent option for processing farms.

How to assemble a mini-tractor with your own hands?

After the drawing is drawn up, you can start preparing the necessary parts. You should have the following available:

Not every owner will find the above items in his household. Therefore, be prepared for the fact that you will have to go through the flea markets, and also look at sites selling spare parts. Surely on one of them you will find the parts you need at bargain prices.

Frame

For making a fracture most often they use a metal channel No. 5 or No. 9. This material is best suited because it has the necessary bending strength. Based on the channel, you will have to make two half-frames by welding. After that, they are connected to each other using hinges. A truck driveshaft can be used as a fastener.

Perhaps a fracture will not suit some people. In this case, an all-metal frame may be an alternative. This design contains the following elements: right and left side members and front and rear cross members.

To create spars, you can take channel number 10. And to make the rear and front cross beams, you can use channels No. 16 and No. 12. The transverse beam can be made of metal beams.

Engine

On a homemade mini tractor Any engine can be installed, the main thing is that it has the necessary power. In order for homemade equipment to be able to cope with all tasks, it is best to equip it with a 40 hp power unit. With.

In most cases, the following types of motors are used for homemade mini tractors:

Also, instead of them, you can borrow an engine from domestic passenger cars of the Zhiguli or Moskvich brands.

In that case, if you decide to stick with the 4x4 option, then you will have to modify the M-67 engine: it is necessary to increase the transmission gear ratio. If this is not done, then the power of the power unit will be insufficient for the equipment to move. Also make sure that the motor is equipped with an additional cooling system.

Transmission

As a gearbox and power take-off shaft, you can borrow the necessary mechanisms from the GAZ-53 car. The clutch can be taken from GAZ-52. Keep in mind that these components will need to be modified.

One of the tasks you need to solve at this stage is to ensure that the clutch is synchronized with the engine. For this welding of a new clutch basket is being carried out, after which it is modified, giving the required dimensions. Certain manipulations will have to be performed with the engine flywheel, the rear plane of which must be shortened and a hole must be created in the center. If your farm has a lathe, then you can easily perform these operations.

Steering

Considering that this mechanism is intended for use on a mini-tractor, it has hydraulic cylinders must be present. In this case, your homemade equipment will be more manageable. Keep in mind that the hydraulic system is a complex mechanism, so you cannot make it yourself at home. Therefore, you will need to find suitable agricultural equipment and borrow from it the hydraulic system available there. For hydraulics to work properly, oil must flow into it, and therefore you need to get a pump.

Rear axle

This you can borrow the mechanism from a car or truck , and then put it on your homemade mini tractor. However, first you will have to modify it: you need to reduce the axle shafts using a lathe.

In the event that you do not find a ready-made bridge, you can assemble it from different machines. Keep in mind that the rear axle will play the leading role. Therefore, for the front one, you can use any available mechanism, the main thing is that it matches the required dimensions.

Wheels

Looking for wheels for a mini tractor, consider their radius, which must correspond to the purposes of using the technology.

If you are going to transport cargo with this machine, then it is best to choose disks with a radius of 13 to 16 inches.
If you need a mini-tractor to carry out agricultural work, then it is recommended to install wheels of 18–24 radius on it.

Conclusion

Private farms face many challenges every year related to care land plot. In order to spend less time and effort on such work, special equipment is needed. Not everyone can afford buying a factory tractor, so many are considering the option of making a homemade mini-tractor with their own hands. Making such a machine is not so difficult, since it uses components and mechanisms from other types of equipment. However, in order assembled car turned out to be in working condition, you first need to draw up a drawing and adhere to it throughout the entire assembly process.

A mini tractor is exactly the same agricultural equipment as a tractor, but with slightly less productivity, which is sacrificed for the sake of maneuverability and efficiency. In addition, some specimens are so light that they can be transported in a trailer. Small tractors perform all the same tasks as their larger counterparts. high class. You can also attach attachments to them for cultivating and fertilizing the soil, cleaning the area and transporting various loads. In addition, many tractors, even those made independently, have a rotation drive auxiliary units and hydraulics.

It differs from a walk-behind tractor, first of all, in that it is a full-fledged agricultural machinery. Of course, a powerful walk-behind tractor also has considerable functionality, but when operating it you have to walk all the time. This is very tedious, especially when cultivating a large area of arable land. And by doing this with a self-propelled machine, even the smallest one, the operator gets much less tired.
Understanding all the advantages of mini tractors, domestic inventors sometimes create first-class examples with their skillful hands, and on the Internet you can now find many descriptions, diagrams and even ready-made drawings of such homemade products.

Mini tractor designs

For the most part, when making a tractor, amateur designers simply remake some serial product, adding some components and eliminating others. This is an easy way, but it is not always feasible, because... a complete machine must be available.
And the design of homemade tractors created from scratch is individual in each case, so today the variety of solutions is simply off the charts.
For example, the frame for a minitractor is made solid and breakable (called “fracture”), the rotation is made with steered wheels and onboard, the layout is classic or in the form of separate modules, allowing you to change the purpose of the device. Install the hydraulic system and power take-off shaft.

Tractor from the manufacturer at the price of a homemade product - the whole the lineup. We buy good attachments for a homemade agricultural machine using the link. Read in this article - the easiest way to assemble a mini tractor from a walk-behind tractor.

The homemade mini tractor offered below is one of the easiest to manufacture and allows you to get by with affordable materials and parts.

But, of course, anyone who is planning to do something themselves, with their own hands, is recommended to have technical skills, the ability to work with tools and read drawings. And, most importantly, have a lot of time and a great desire to do it.

Frame

It is made from rolled metal. Calculating strength is a thankless task (and in this case, unnecessary), so you just need to lay down a multiple reserve in advance. Based on this, use a channel from No. 6 to 12 - best solution for a homemade mini tractor. It is not worth making any “cuts” and “bending around” the units, because This will greatly complicate and increase the cost of the project. An ordinary flat “ladder” is simple and accessible to many.

As practice shows for a homemade tractor, it is more useful to use a channel of a larger rolling size (up to 20) as the front and rear traverses (cross members), because subsequently, it is to these traverses that various working parts are attached and auxiliary equipment. Moreover, it is better to place it with shelves inside. The channels of the side members (longitudinal beams) can be placed both inward and outward. Fuel lines and lines are laid inside the side members, which are naturally protected.

The most shaped simple design homemade frames are a rectangle with two or more traverses, but a frame in the form of a trapezoid will have much greater rigidity. The width in the front part should be smaller to accommodate the minimum dimensions of the steered wheels, as well as to allow monitoring of movement strictly along the arable row. The joints between the side members and the traverses must be reinforced by welding gussets.

Layout

The relative arrangement of the units of any tractor has historically developed a long time ago.
Classic layout self-propelled vehicle the following: the engine is located in front, longitudinally, above the front axle. A gearbox is connected to it through the clutch, followed by a transfer case and followed by a drive axle. The shafts of the units are connected to each other using cardans and (or) couplings.

Compliance with this scheme will be the best option when creating a mini tractor, because will allow you to use existing units without changing them.
According to the experience of many creators of homemade tractors, it is better to assemble the units “in place”, without doing unnecessary drawings and calculations. The best option- place all the main components and homemade mechanisms on the finished frame, installing them on temporary supports (conveniently, on wooden blocks), and, having found the best mutual position, make mounting brackets. But we must not forget that all components on a homemade tractor must be secured through supports that dampen vibrations (rubber cushions). It is best to borrow them from the same equipment from which the unit was taken. Another important factor needs to be taken into account. This is weight distribution, i.e. distribution of the total weight of the minitractor along the front and rear axles. The most acceptable option is that 60% of the weight falls on the drive wheels, 40% on the steering wheels.

Engine for homemade

From the point of view of thrust-to-weight ratio, weight, availability and low cost of repair, it is most logical when manufacturing a tractor at home to use an engine from classic VAZ cars - from 2101 to 2107. They can be found in good condition at the price of scrap metal. If you're lucky, one car can become a donor for most of the parts for a mini tractor.

The motor with clutch and gearbox are fixed as a single unit, which simplifies the work on a homemade tractor and saves the creator from many difficulties. Be sure to install a fan impeller on the shaft of the water pump (“pump”), even if it was not there. After all, the speeds of agricultural machinery are much lower than those of automobiles, so the operating mode of a mini tractor engine is the same as when standing in a traffic jam, which is considered difficult for any engine. Consequently, the radiator of the cooling system of a homemade tractor requires forced airflow.

Transmission

As mentioned above, it is advisable to install the entire power plant on a homemade product. In this case, what will later become a mini tractor will already have at least four forward gears and one reverse gear. All that remains is to coordinate the optimal tractor engine speed and the desired speed. For this, a transfer case from any all-wheel drive car will be quite sufficient. The most suitable option is UAZ. By the way, you can also use the previously discussed components from the UAZ, but they are heavier, the consumption of the resulting tractor will be higher, and all its power will be rarely used.

A good element for connecting shafts - elastic coupling, which is installed on the output shaft of the VAZ gearbox. Having made a flange to transfer case, you can do without an intermediate cardan. But from the transfer case to the drive axle, a cardan is required, because the loads there are significantly higher, and the coupling will not withstand them.
Drive axle at self-construction tractors are best used from a UAZ vehicle that has final drives. This will increase, firstly, traction, and secondly, ground clearance (which should preferably be increased to 450 mm). The required track size for a homemade mini tractor is obtained by cutting the bridge stockings (narrowing it) or making spacers for fastening the wheels (widening it), because The nominal track of the UAZ is 1445mm, which does not coincide with the accepted ranges for agricultural vehicles (1260-1285, 1350-1370, 1490-1515, 1790-1815).

Chassis and propulsion

This system in the homemade mini tractor under consideration almost completely replicates that of tractors produced by industry and differs from the automobile system in some important points. The main difference is the absence rear suspension, i.e., the drive axle is not attached to the frame on springs, but is rigidly fixed to it. This must be done if you plan to build not only the tractor itself, but also all the agricultural implements for it with which it is supposed to be used. Since such attachments as plows, harrows, mowers and others, attached to the rear of a homemade mini tractor, place a very heavy load on rear axle and, if the latter has rear suspension, it will quickly render it unusable. The front axle on a homemade tractor can also be installed without suspension, comfort will not be significantly reduced. It is convenient to use forks of cardan joints of trucks (ZIL, KAMAZ, KrAZ) as turning axles, spare parts for which can be found in motor vehicles and at metal receiving yards. Two forks are welded to the beam, or directly to the frame, maintaining alignment, and two counter forks are welded to the steering knuckles of the donor car. The steering linkage along with the entire steering mechanism is also borrowed.

There is no point in using the brake system in its “automotive form” on a tractor made by hand, because wrong speeds. Only enough parking brake. However, the mechanism is driven not from a lever, but from a pedal with a fixed pressed position. Then the homemade product can be slowed down in motion and fixed in the parking lot. It is best to use wheels from agricultural machines, because... they have the required tread, but it is quite possible to adapt tires from SUVs or light trucks by cutting them into the desired tread pattern (better - herringbone, for self-cleaning). Tire pressure is adjusted empirically to find the optimal combination of comfort and performance.

Electrics on a homemade tractor

You can use any parts from anything, the main thing is that the voltage of the generator and consumers match. We must not forget that accumulator battery- This is a container with acid, so it must be secured very firmly. The recommended solution is to place it under the seat of the mini tractor in a special box, or simply in a fence.

Headlights and side lights, as well as brake signals - elements are desirable, but not required, because You can only exploit the result of your labors away from other transport.

Driving on the roads

Not all homemade mini tractor designers make it onto public roads. And this is correct, because. Our country lists a number of strict requirements that must be met by vehicles moving along them. Even if everything turned out well and the product meets all the requirements, certification will be required to confirm this, which is very expensive.

Therefore, it is prohibited to drive on the roads on a homemade tractor. If you have to deliver it to the work site, it is better to do it on a trailer. This is one of the reasons why they are trying to make homemade work easier.

An important component of agriculture is the cultivation of land. This includes not only regular loosening and weeding, but also watering and fertilizing the land. After all, absolutely all crops need plowed and well-tended land. A mini tractor, which has small dimensions and is capable of performing a lot of everyday tasks in agriculture, can easily cope with such difficult tasks.

In this regard, in rural areas, small farms prefer this technique. Indeed, unlike large agricultural complexes, private owners cannot afford expensive agricultural machinery. This is why homemade mini tractor videos with detailed descriptions of which are available on the Internet have become so popular and in demand. Assembling such equipment is not as simple as it might seem at first glance, but it is still possible, and the costs will be much lower than the cost of factory-made agricultural equipment. Plus, a homemade small tractor can be equipped with various equipment that can significantly increase the range of work performed by this equipment.

Mini tractors: types and features

As always, this category of equipment includes 3 types, with their own characteristics:

1. Devices that can handle any task: hilling, loosening and weeding of land, as well as garbage collection and grass mowing. In most cases, such equipment is equipped with a medium-power engine and can cope with the processing of five or even six hectares of land. Various attachments also help in performing the tasks assigned to the mini tractor (see).

2. Small tractors, assembled exclusively for mowing grass and cleaning areas adjacent to a house or agricultural land, can easily cope even with an area of about two hectares. This technique is often used to create lawns.

3. A rider is a technique created to maintain a small plot of land, and is used mainly for fertilizing the land, as well as treating the area with pesticides. It is also used for cleaning concrete sites and other similar areas.

Pros and cons of this technique

In most cases, a homemade mini tractor is used in private agricultural farms: with mini tractors they not only remove various debris from trees and shrubs, but also maintain vegetable gardens, and also improve the surrounding areas. The advantages of this technique include the following:

Thorough treatment of any soil. It is extremely difficult to cultivate the land on your own, especially large volumes, and even more so to do it efficiently. Indeed, in some places the soil may be not only hard, but also rocky, so everything must be done necessary work, manually is quite difficult. Homemade mini tractors cope with any of the above tasks no worse than conventional factory equipment;

It is easy to cultivate even small areas of agricultural land. For small areas, it is simply impractical to incur costs for the purchase of large factory equipment, since a mini tractor is much cheaper and copes with the assigned tasks;

Attractive price homemade equipment, since the mini tractor is assembled mainly from improvised means and inexpensive parts;

You can always, if necessary, change additional equipment, depending on what work needs to be done. And, of course, simple and fairly affordable repairs.

The only disadvantage is that you need to independently select all the components and devote your precious time to this, which you need quite a lot, especially if you come across some rare components in the equipment.

But, it should be noted that in most cases, the assembly uses the most common and accessible parts that can be found at any time. A video of people who already have some experience in this matter helps you assemble a homemade mini tractor with your own hands.

How to make a homemade mini tractor?

To create such agricultural equipment, specialists from the people use several methods, but in most cases everything happens something like this:

1. A frame is created from a conventional rolled channel by welding pre-prepared elements, which include front and rear cross members and two side members. The front part of this technique is made narrower, resulting in a trapezoidal frame. After that, holes are made in the frame for installing other parts of the body and mechanisms.

2. By welding, corners are attached to the corners of the frame, which play the role of a stand, and also serve as a subframe and are connected to each other at the top. Next, the rear axle is mounted on the frame, but when designing all-wheel drive vehicles, it will be necessary to install the front axle as well.

3. An engine of the required power is mounted, in the role of which various power units from walk-behind tractors (see), motorcycles (even boxer ones) are usually used.

4. A gearbox is mounted on the frame, which must be facing the driver in order for control to be as comfortable and simple as possible.

6. It is imperative to weld a tow bar, which will later be useful not only for the trailer, but also for some additional equipment, such as a seeder, mower or plow.

7. The final point in creating a mini tractor is the installation of the brake system, installation of the tank, and, of course, the electrical part.

Homemade drawings

Well, to make a choice, any person who wants to construct such equipment will be helped by the drawings of homemade mini tractors that are available on the Internet.

Homemade models of mini tractors, photos and videos of which can be found on the pages of designers of conventional homemade equipment for the agricultural complex, have not only a quite decent exterior, but also excellent functionality. Creating one of the models of agricultural machinery can be quite long and not easy, but a video detailing the step-by-step construction of a mini tractor can help facilitate the design process. As a result, it is possible to create equipment that will help process agricultural areas much faster and more efficiently.

The use of mini tractors in agriculture has become increasingly justified recently. Relatively small dimensions, coupled with good performance productivity and maneuverability, allow you to process land holdings for the purpose of their further use. However, not everyone has the opportunity to purchase a ready-made unit sold in a specialized store, because its cost can reach up to 100 thousand rubles. It is then that the question arises for many - how to assemble a mini tractor at home with your own hands?

The solution is not as simple as it might seem at first glance, because assembly may require quite a lot of accompanying material, as well as the necessary technical knowledge and ability to work with tools.

Areas of application of a homemade mini tractor in the household

And in general, you can use the Internet by entering the request “do-it-yourself mini tractor, drawings, dimensions” into the address bar, and you will immediately see more than one detailed diagram assemblies.

The frame is the supporting structure. All attachments are attached to it.

This step is very important, because self-production any unit requires some modification and adjustment to the required parameters. Obviously, the easiest way to do this is to follow a drawing rather than use an approximate guide.

For successful and productive management household appropriate agricultural machinery is required. By clicking on, you will learn how to make a cultivator yourself.

The plows have improved characteristics, which allows you to easily cope with plowing any land as quickly and efficiently as possible. all about the different types and characteristics of the PSK plow.

Currently, technological progress is helping to replace long human labor with much more efficient machine work. Combine harvester Polesie is your indispensable assistant with excellent quality for decades.

In addition, the same turner will understand what is required of him by looking at a detailed drawing rather than a formal explanation in words.

At the project planning stage, it becomes clear what kind of unit will be in the end. The DIY mini tractor, located on an articulated frame, is quite popular among many.

However, this is far from the only way assembly, so the choice lies solely with the person who will carry out the manufacturing.

Having decided on the type of mini tractor, the question arises of searching necessary spare parts and components. We are talking about the frame structure, engine, transmission, controls and wheelbase. Most of this can be found on the Internet by visiting sites that specialize in selling various spare parts.

The assembly process itself will include several stages:

Making the frame. The fracture is carried out mainly from channel number 5 and channel number 9. Two half-frames need to be welded from these components, and they will be connected to each other using a hinge. In this capacity, driveshafts from heavy-duty vehicles can be used.

There is another way to construct the frame. It consists in the manufacture of a one-piece structure consisting of two traverses and two spars. The crossbars are made from channels number 16 (for the rear) and number 12 (for the front).
The spars will be made from channel number 10. A metal beam is used as a cross member.
As an engine, you can use models MT-9, UD-2, UD-4, etc. Their power will be quite enough for a homemade version. In principle, any engine with a relatively high power– approximately 40 hp
The PTO and gearbox can be removed from the GAZ-53, and the clutch can be taken from the GAZ-52. Remember that these parts will have to be adjusted to the design parameters. You need to cut off the back part of the motor flywheel a little and also drill a hole in the center.
Steering wheel can be provided hydraulic system, which needs to be taken from old agricultural machinery.
The design of the rear axle can be borrowed from old passenger cars, but it will have to be slightly adjusted on a lathe.
Any suitable wheels can be used, but their diameter should be about 18 inches - this is the acceptable minimum for agricultural work.
In this sequence, in principle, lies the answer to the question - how to make a mini tractor at home? Most of the necessary components can be obtained from old equipment, which greatly simplifies the issue of finding the right part.

In addition, the costs are minimal, because even purchased parts will cost much less than a finished mini tractor.

Advantages and disadvantages of manual assembly

Perhaps the main advantage of a homemade mini tractor is the absolute savings in money compared to purchasing full-fledged units in a store, such as,.

At the same time, its performance indicators will not differ much from the factory versions, because the design uses a fairly powerful motor, which is quite enough to cultivate land holdings of up to ten hectares.

The manufacturing costs for a mini tractor pay off in almost one calendar year, because most of the components are taken from old equipment, or the costs of purchasing them are minimal. Many people adapt other equipment, such as a walk-behind tractor, to the minitractor, which further simplifies the assembly process.

In addition, homemade units have other advantages:

Relatively high degree of immersion into the soil. If everything is planned correctly, the digging depth will be identical to that shown by purchased analogues. Be that as it may, it is still better than digging up the garden by hand.
Quite high mobility, due to fairly modest dimensions. The use of such units is advisable specifically in small gardens and summer cottages, where large tractors cannot turn around.
Due to the fact that you make the mini tractor yourself, there is the possibility of additional modernization of the unit. You can remove components, replacing them with other, more powerful ones, or add new devices.
In mini tractors sold there is no such possibility; moreover, the operating instructions explicitly state that making any changes to the configuration is strictly prohibited.

Among the disadvantages the following points can be noted:

Relatively difficult process assemblies. Here we are talking not only about direct work, but also about certain difficulties in selecting the necessary components. Many of them have to be adjusted on a lathe, which in itself represents an additional complexity.
The likelihood of breakdowns, after all homemade version It is made mainly from old parts and spare parts.

In principle, the pros and cons are approximately equal in degree of importance, but there is one small digression. Today's realities are such that the issue of price becomes dominant, overshadowing other arguments.

A detailed explanation of this phenomenon is unnecessary, because economy has always been decisive, regardless of where it is applied.

Additional tips and warnings for making your own tractor

Before you begin full operation of a homemade mini tractor, you need to register it with the traffic police.

This is not a mere formality, but an understandable necessity, because when driving on public roads, you may be subject to fines, and the unit itself may be transported to a impound lot.

Concerning technical aspects, then there is its own specificity. So that the engine of a homemade unit produces the necessary parameters, i.e. about 2 thousand revolutions at 3 km/h, you need to slightly adjust the transmission diagram. In general, ideally, each wheel of the rear axle should be equipped with a gearbox.

If the basis for a mini tractor is a walk-behind tractor, for example, or some other, then it is better that it has a special hitch that allows you to attach it to optional equipment. In general, you should carefully select the model of walk-behind tractor that you want to convert into a mini tractor.

For these purposes, the Centaur walk-behind tractor, which has a power of 9 hp and also has the necessary technical data required for conversion, may be perfect.

Conclusion

Making a homemade mini tractor is becoming increasingly important, especially for owners of small plots of land. The fact is that the use of large-sized tractors may be impractical, because they will not be able to show all their performance indicators on such a small plot of land.

In addition, fuel costs can become a truly unaffordable burden for private farmers.

Savings also explain the refusal to purchase a mini tractor in a special store, because agriculture is far from the most profitable type of business in our country. Therefore, for an ordinary summer resident, the best option would be to manufacture the unit on their own.

The costs are cheap, and the performance of a finished homemade mini tractor may pleasantly surprise you. Naturally, if you use a relatively powerful engine and not very old spare parts.

Do not forget that this method may not be suitable for some people who do not have the proper skills in handling a welding machine or a lathe, for example. In this case, you can simply order the necessary parts from the craftsmen who will manufacture them.

You will, of course, have to pay, but no more than the amount that you need to pay for a finished mini tractor.

The main types of homemade tractors

A farm tractor can belong to one of several varieties, including:

multifunctional equipment;
homemade tractors with the function of collecting garbage and mowing grass;
riders.

The first type is equipment with which you can cultivate the soil, remove debris, and also cut grass. Homemade tractors are usually equipped with medium-power power units. Multifunctional equipment can cope with an area of 6 hectares. If necessary, you can install attachments on it, thanks to which the list of tasks expands.

Tractor manufacturing features

If you decide to make a homemade tractor with your own hands, then at the first stage you will need to make a frame for which a rolled channel is used. The design contains traverses, and they should be located at the back and front. In addition, the system has side members. When the frame is created, the width of the front part is slightly reduced, which gives the part a trapezoidal shape. A hole must be created in the frame, thanks to which other devices and elements can be strengthened.

Work methodology

Now you can begin installing the steering components. A steering wheel is usually used for this. This part is usually borrowed from a domestic passenger car model. In some cases, a motorcycle handlebar is used. A trailer will need a tow bar. It is installed at the next stage, welded to the frame. When making a homemade tractor with your own hands, you need a brake system and a tank, which must proceed to connecting the electrics.

Assembly instructions: frame

Powertrain, axle and track

Before you make a tractor, you must take care of the presence of a caterpillar. The simplest option is a design with rollers made of tires and wheels. They can be taken from carts. Taking into account the size of the tractor, you should select the dimensions of the wheels. The caterpillar can be made from a large tire, which is pre-cut on the sides.

Additional equipment of the tractor with an engine

A homemade tractor with a VAZ engine can be found quite often, as well as installations of the following types:

M-67;
UD-2;
MT-9;
UD-4.

You can equip the tractor with an engine from a Moskvich or Zhiguli car. When it is intended to make a homemade product according to the 4x4 formula, for the M-67 the transmission gear ratio is increased. Otherwise, the power plant will lack power to provide force to the wheelsets. It must be taken into account that the power unit may require an additional cooling system.

Additional transmission information

What else you need to know about the rear axle and wheels

A mini-tractor for snow removal can be equipped with a rear axle from a truck or car. The axle shafts are pre-shortened on a lathe. If a ready-made bridge cannot be found, then designs from different machines can be used. Experts recommend using any unit that fits in size, because the front axle does not act as a drive axle.

Equipment for a homemade tractor

The described equipment includes a frame for a homemade tractor. After assembly, it is necessary to install the drive wheels and road wheels. The power unit is installed at the next stage, then comes the turn of the gearbox. The differentials and onboard brakes should be installed in the next step, after which all components can be connected to the gearbox.
