Preparing to create a homemade mini tractor
The process of creating a homemade mini-tractor begins with drawing up a drawing, a kinematic diagram of the future “plowman” and preparing the necessary materials, tools, equipment. If you have the skills, you can develop a scheme for demonstrating the mechanisms and components of the tractor yourself, if not, find a suitable option on the Internet or use the example presented here.
As for the parts and components involved in the modernization of the walk-behind tractor, you can use a purchased factory kit to convert it into a mini tractor. But this option is not suitable for those who want to make, for example, an all-wheel drive (4×4) tractor and at the same time significantly save money. Therefore, you will have to look for upgraded parts.
So, to create a homemade tractor you will need:
- set of tools;
- welding equipment;
- drill with a set of drills;
- metal pipes, channels;
- fasteners, hardware (bolts, nuts);
- angle grinder, discs for working with metal.
Also, in order to make a tractor with your own hands, you will need two suitable wheels, a hitch, a driver’s seat, a steering gear, pedals and, of course, a single-axle tractor with sufficient weight and power. It is better to opt for a heavy-duty unit with a diesel engine (the Zubr, Neva, Agro, SCOUT models are well suited). This will make it possible to get, as a result of the alteration, a self-made, but productive mini-tractor, capable of effectively performing various agrotechnical operations. Surely you want him to carry out not only agricultural functions, but also be able to pull a trailer.
The weight of the unit to be selected must correspond to the state of the soil on which it is planned to use the homemade product. If it is compacted, dry, then the future mini-tractor is unlikely to cope with the tasks assigned to it. Therefore, the harder the soil, the harder the cultivator will be needed. And the power of its engine should be correlated with the area of the land plot on which agricultural work will be carried out using a motorized tractor. So, the larger the plot, the higher this parameter should be.
Installing the undercarriage
At the end of the installation, the hitching devices are installed on both axles (front, rear), and already on them. the wheels. The rear axle is usually attached to those that came with a walk-behind tractor (SCOUT, Zubr, Neva), and wheels from a passenger car or some kind of agricultural machinery are fitted to the front axle. It is important that they have a deep tread. this will make a homemade mini-tractor a high-cross country vehicle and with improved traction of the wheels with the ground. Then the management will be much easier.
To equip a home-made tractor with a full-fledged front running gear, they buy hubs assembled with a brake system and, preferably, complete with steering rods, a steering wheel, a gearbox and a steering column. They can also be altered by removing them from supported cars.
Fastening the front wheels to the mini-tractor is carried out in this way:
- A metal profile pipe is selected that corresponds to the thickness of the front axle of a homemade tractor.
- Wheel hubs are attached to the ends of the profile.
- The hub design is fixed to the front frame directly in the center.
- The steering rods are mounted, after which they are aligned with the steering gear.
- Fix the gearbox on the frame.
- Put the steering rod, steering wheel.
- Adjust the steering column, steering wheel.
Sometimes the front suspension of the tractor is supplemented with spring shock absorbers to provide more comfortable working conditions. After the steering column has been assembled according to the drawing, you need to install the rear wheels.
The rear axle of the cultivator is mounted on bearings tightly pressed into spherical bushings. A pulley is mounted on it, which will transmit torque from the engine to the rotating nodes. You can leave the rear wheels without a differential. this will simplify the design and minimize the slipping of the future mini-tractor when operating on loose soils.
The optimum diameter of the tractor wheels is 30-36 cm (as in the SCOUT T-15 model). If you put a homemade diesel unit on smaller wheels, it will simply roll forward. Fitting large wheels will make the machine uncontrollable and impair its maneuverability, especially when working with a trailer. At the end of the installation of the wheels and steering column, the layout of the main unit of agricultural machinery. the engine.
How to make a mini tractor from a walk-behind tractor with your own hands
Every farmer knows that it is easier and more convenient to cultivate summer cottages and household plots with the help of a small tractor. And it doesn’t matter if there is not enough money to buy a factory “iron horse”. you can make it yourself from an inexpensive walk-behind tractor. over, when there is an interest in technology, engineering skills, the necessary equipment and tools, it will not be at all difficult to do this. The main thing is to understand the technical aspects, prepare for the transformation and choose the right single-axle tractor itself. Then the refurbishment can begin. By the way, the manual of the walk-behind tractor may contain a drawing that will help you understand how best to make a homemade product.
Mounting the engine and hydraulics
The most profitable option for converting a walk-behind tractor into a homemade four-wheeled tractor is a single-cylinder water-cooled diesel engine. this is usually installed on Chinese motor-cultivators of the SCOUT brand, Zubr and the Russian Neva. A single-cylinder diesel engine is economical, so the operation of a mini-tractor produced on its basis will not be invoiced. It is typically placed on the front of the frame, allowing the small tractor to maintain optimal balance when operating with additional tools. At the location of the motor, a mounting system is installed, which is better to make “floating” (sliding) in order to simplify the adjustment and tension of the belts.
The transfer of power from the motor to the rear wheels of a homemade tractor is organized using a belt drive. The PTO transfer case, like the gearbox, can be used from a decommissioned GAZ-53 vehicle. The homemade power unit is mounted in such a way that the PTO pulley is located in the same plane with the pulley located on the rear axle of the mini-tractor. At the same time, they outline the location for the clutch pedal. The belt drive is covered with a protective cover to avoid slipping during operation and to make its service life longer.
After completing the main work, a hydraulic lift is installed on a homemade mini-tractor with an engine from a walk-behind tractor. The conversion hydraulics kit should include an oil pump, oil reservoir, hydraulic cylinder and distributor. All components of the system are connected by flexible oil-resistant hoses. It is advisable to make the hydraulics in a floating mode. this will ensure the full operation of the tractor hitch. Then the tiller will work as it should.

Then the driver’s seat is installed.
Installation of the brake system and electrical equipment
To begin with, determine the place (using the layout diagram) where the brake pedal will be located in the alteration. On the designated plot, mount the pedal mount and the main brake cylinder. Then the cylinder is connected with hoses to the brake drums located on the front wheels of the converted tractor.
Immediately after this, the brake system is checked for leaks, and if it is broken, it is redone again. To avoid ridiculous mistakes, it is better to use a visual drawing, which shows all the main components of the tractor. For control, the system must be pumped over and the remaining air is removed. This will make it workable and provide proper functionality. The system can also be supplemented with a parking brake.
The next stage of self-alteration of a walk-behind tractor into a full-fledged mini-tractor is the connection of electrical equipment and the output of sensors to the dashboard. It is recommended to do this for the convenience and safety of vehicle operation. A temperature meter, a liquid cooling indicator, an ignition key, an oil pressure sensor and a fuel level in the gas tank are displayed on the panel. On request, a home-made tractor is supplied with a sound signal, brake lights and direction indicators.
Additionally, agricultural machinery can be equipped with cladding elements and a canopy. This will give the mini tractor an attractive appearance and make the operator’s work more comfortable. After completing the process of modernizing the walk-behind tractor, you should run in a home-made mini-tractor so that the parts are “lapped” and the lubricity of the mating surfaces improves.
How to make a frame
After preparing the tools and accessories necessary to create a mini-tractor, they begin to “reshape” the walk-behind tractor frame in order to adapt it to an additional pair of wheels. The platform of the future home-made machine can be made all-metal or break-through using channels or shaped metal pipes. Longitudinal and transverse spars are easy to make. they are cut with an angle grinder and connected by electric welding or fasteners. For greater reliability, bolted connections are combined with additional welding of seams.
When transforming a cultivator into a mini-tractor, it is often a fracture that is used, consisting of two independent half-frames, connected to each other by means of hinges. Thanks to this design, all four wheels of the tractor are almost always in contact with the ground, and they practically do not hang out when using homemade products on an uneven surface or slippery road. This allows you to increase the stability of a mini-tractor from a walk-behind tractor, improve its maneuverability and cross-country ability when carrying out arable and transport operations.
A hinge device is mounted to the front or rear section of the prepared frame according to the scheme, which will allow the tractor to make it possible to work with auxiliary devices. You can weld a towbar immediately behind for towing a trailer. this will further expand the functionality of a homemade motorized tractor.
Advantages of homemade tractors from motoblocks
The advantages of owning such a unit are obvious. Unlike a walk-behind tractor, it will allow:
Using the skills, you can turn an ordinary motorized cultivator with disabilities into a multifunctional and efficient mini-tractor. Maneuverable and compact, it is able to work even in densely planted areas, between bushes and trees, as well as in a limited local area, without spoiling the paving slabs and asphalt pavement. Look at the form where there is a video about the work of homemade equipment.
To make a mini-tractor from a walk-behind tractor means to buy yourself agricultural machinery with the broadest functionality. Together with it, you can use a variety of attachments: cultivator, potato planter, cutter, harrow, rotary mower, plow, hillers, etc. And if equipped with a hydraulically driven stacker, then a homemade tractor can also be operated as a stacker or a crane. Thanks to its practical design, working on such a homemade product is simple, comfortable and safe. And the remaining motoblock parts can be used to create other homemade products. A homemade mini tractor is better than the most expensive heavy motor cultivator and cheaper than a heavy tractor.
Instructions on how to make an all-wheel drive mini tractor with your own hands. drawings and dimensions
Having appreciated all the advantages, many are wondering. how to make a 4×4 mini tractor? In principle, this assembly method is not much different from traditional methods, except, perhaps, the structure of the frame structure.
Basically, the frame is solid, but in the breaks, an option with a breaking frame is provided, from which the name itself comes.
The appearance of the structure may be a little puzzling to an outside observer, but its seeming unpretentiousness should not be misleading. The fact is that everything inside is located so proportionally, if you follow the drawings exactly, which allows the unit to show quite good performance indicators.
Speaking of drawings. This is probably one of the most important stages of the entire assembly, because the success of the entire design depends on the correctness of leaving a detailed drawing and determining the exact dimensions.
The fact is that the specifics of self-assembly involves the adaptation of some parts to the individual characteristics of the frame or power unit. This is understandable, because the components are taken from completely different equipment, which leads to their dimensional mismatch.
The adjustment itself is carried out mainly on a lathe, which in itself presupposes the presence of a detailed drawing. After all, it is much easier to make certain holes or grind, looking at the drawing, than keeping all this abstraction in your head.
So, having made a drawing, we proceed to the assembly process:
Electric walk behind Tractor movie.
- The frame itself will consist of traverses and side members. The spars, in this case, have a three-stage structure. The first stage is made of channel number 10, and the last one is a square steel pipe with dimensions of 80 × 80 mm.
- The rear traverse is made of channel number 16, and the front one is made of channel number 12.
- If you are converting a single-axle tractor into a mini-tractor, then the main power unit will be the engine located on the walk-behind tractor. If not, you will have to purchase the engine separately. In principle, any diesel engine of the required power (at least 12 hp) can be used.
- However, experts advise taking a more powerful one. a motor with 40 hp. and water cooling.
- The gearbox and power take-off shaft, as well as the clutch, can be taken from the GAZ-53 and GAZ-52 vehicles, respectively. They will not work ready-made, so you will have to modify them a little. To do this, you need to re-make the flywheel of the motor, cutting off a little from the back and drilling one hole in the middle.
- The bridge can be installed in the unit in the desired form, without making any manipulations. It is attached to the frame structure with four ladders.
- Wheels can be taken from old cars, but 18 inches is considered the optimal diameter. The process of installing the wheels on the hubs itself is quite simple. It is enough to cut out the hole required in diameter from the center of the disk, and the center of the disk from the ZIL-130 is welded to this place.
- The front axle is not so important, because it will not be the driving one. Therefore, you can take a bridge from another technique.
- The steering is best hydraulically assisted. You can take it from old agricultural equipment, but for its correct operation you need an oil pump.
- By the way, the driver’s seat must also be installed correctly, because a person spends not a single hour controlling the unit. The seat must be positioned so that the steering column does not rest on the knees of the person.
In general, the assembly of a homemade all-wheel drive minitractor is carried out using third-party spare parts, among which, mainly, automobile.
In particular, the drum brake will be used in the front wheelbase system, and the steering rack will be borrowed from the cars of the VAZ family.
Other components can be freely found on the spare parts market, where there are quite a lot of useful things. In addition, on specialized sites there are a sufficient number of advertisements for the sale of parts that can be purchased for mere pennies.
Advantages and disadvantages of a homemade design
In a crisis, the defining moment that affects many areas of life and industry is the issue of saving money. It is this circumstance that pushes many enthusiasts to independently manufacture not only mini tractors, but also other agricultural equipment.
Modern grain crushers are quite compact and energy-intensive, they are easy to use and delight their owners. Household grain crusher. ideal in terms of price and quality.
To facilitate labor and increase productivity, various types of manual cultivators have been created for cultivating the soil in the country. gasoline, electric, manual, light and heavy. By clicking on the link, get acquainted with the manual cultivator for summer cottages.
In the last decade, among summer residents and gardeners, an apparatus has become famous. a sprayer, which has the name “Beetle”. Here is all the information about this wonderful device.
This fact, in many respects, becomes decisive, especially for rural areas, where there has been no employment for a long time, and, as a consequence, no money. All that people living in villages and villages have is their personal economy, which feeds them throughout the year.
Therefore, homemade units in rural areas will be popular for a long time.
In addition to the obvious cost savings, self-assembly has a number of advantages:
- Due to its compact dimensions, a home-made unit is capable of performing work in fairly small areas. Given that most private gardens are small, this circumstance becomes important, because the use of large-sized equipment, in this case, is inappropriate.
- A quick return on investment. literally in one season. This is a consequence of the savings on components that were described earlier.
- Quite good performance, which is demonstrated by a homemade unit.
However, no matter how you might want to, homemade mini tractors also have certain disadvantages that must be pointed out:
- When assembling, there is a certain problem of finding the right parts and spare parts.
- A consequence of the previous problem is the issue of repair, because if a certain part fails, it will be quite difficult to find it.
- Self-assembly requires certain knowledge in technology, as well as the ability to work with a welding machine and a lathe. In other words, the assembly is not suitable for everyone.
- Due to the fact that an all-wheel drive home-made mini tractor is made mainly from old components, this may affect the frequency of equipment breakdowns.
As we can see, there are a lot of disadvantages. But, at the household level, self-assembly becomes almost the only alternative, due to its relative cheapness.
Additional tips and warnings about the mini tractor
If you have enough money, you can buy some old Zhiguli, Oka, a single-axle tractor to use it as a “donor” for a future homemade mini tractor.
It is possible to purchase without documents, at the same time it is quite used, therefore, which is relatively small, in comparison with a ready-made mini tractor.
The essence of this advice is simple: in order not to look for spare parts and parts everywhere, you can take everything from one machine, i.e. gearbox, clutch, etc. By the way, the car body can then be sold.
Also, an important point is the registration of a home-made unit in the traffic police. Of course, you can not do it if you do not plan to leave your garden, but for those who plan to use public roads, this action is necessary.
The fact is that a mini-tractor, even a home-made one, belongs to special equipment, therefore, it requires mandatory registration with the inspection. If these rules are not followed, the employee may impose a financial fine on you, and the vehicle itself may be removed to the parking lot.

Here all sorts of craftsmen appear who have adapted to make such units out of all the rubbish that they have in the garage.
What a careless owner would have thrown into a landfill, a savvy and resourceful person is able to make a completely workable device out of this that can perform basic agricultural work.
Home made tractor.
Quite popular, among such craftsmen, the do-it-yourself 4×4 fracture mini-tractor is used, which is a rather bizarre design.
Of course, the power of a home-made unit may be somewhat weaker, but at the level of domestic use, this fact is almost imperceptible.
The main area of application of this do-it-yourself unit is agricultural work. This term covers a fairly wide range, including many related works. In other words, a homemade mini tractor is needed for the following purposes:
- plowing of land holdings for the purpose of their further use;
- cultivation of the soil, as well as getting rid of weeds;
- harrowing the soil;
- sowing operations on treated soil;
- planting and digging potatoes.
In principle, this is the main purpose of the mini tractor, for which it is made. But, its application can be significantly expanded if a special connection for additional equipment, mounted and trailed type is provided in its design.
If everything is done correctly, then your homemade product can additionally perform the following work:
- transportation of various goods (transportation of firewood, construction waste, etc.);
- snow removal in the winter season;
- mowing lawns and lawns and making hay for livestock.
As we can see, the mini-tractor breaking the classic 4×4 with its own hands can significantly facilitate the life of any villager, because with the help of this technique it becomes possible to perform all the type of work that is required with competent maintenance of subsidiary farming.
The indispensability of a home-made unit is also due to the fact that a minimum of investments and funds are used in its manufacture, which is very important for rural areas.
For more information about the operation of an all-wheel drive mini tractor, see
And for the household level, this is the very thing, especially since there is an almost ideal combination of those manufacturing costs and the quality that is obtained at the output and the scope for the selection and manufacture of additional equipment (see do-it-yourself rotary tiller).

How to choose the basis of a mini tractor
Before you make mini equipment with your own hands, you need to choose a model that will act as a basis. In this case, it is required to take into account the following technical characteristics:
- engine power, an indicator of its torque;
- the mass of the future mini tractor;
- type of power unit. gasoline, diesel;
- plow dimensions;
- manufacturer and price.
The area of the territory that can be processed with ready-made equipment depends on the power indicator of the engine of the walk-behind tractor. It turns out that the larger the area, the stronger the unit should be. As for the weight of the device, it must correspond to the type of soil. For dense soil, you will need a heavy mini-tractor made with your own hands from Neva special equipment. And vice versa, with soft ground, you need to use a light apparatus so that it does not tamp it.
The weight of the machine must be suitable for the type of soil. on dense soil you need a heavy tractor, on light, sandy lightweight
When calculating the dimensions, consider the processing depth and ease of use. The best option would be a cultivator with adjustable width. There are models on the market equipped with a gasoline or diesel engine. The first option, when operating, emits a minimum noise level, has a slight compression and an easy start from a half turn. The diesel version is economical and highly productive when working over a large area or with difficult soil.
After completing work on the creation of a mini tractor, you need to treat the body with an anti-corrosion agent and paint it. Next, the equipment needs to be run in, so the operator can make sure that all mechanical components are working.
Once the technique has already been tested, it can be supplemented with a head light, canopy, hydraulics and other devices.
What is required
Before starting work, you should make sure that you have all the necessary parts, materials, and tools.
- uniaxial tractor. It must be chosen taking into account the above recommendations. It is he who will serve as the basis in a homemade mini tractor.
uniaxial tractor Neva. the best option for rework
- Additional wheelset with axle. It is imperative to purchase bearings for the wheels, as well as a steering unit.
- Metal sheets, pipes and corners. The material is needed to create the body and frame of the structure.
- Elements for fixing parts and mechanical assemblies. In this case, washers, bolts, nuts, welding.
To carry out the assembly, in addition to the details, you also need to prepare a number of tools:
- drill-electric screwdriver;
- a set of wrenches of different sizes;
- angle grinder.
A homemade unit has a number of advantages. First of all, this is the cost. Even if the DIY needs to buy a cultivator, they will spend less money anyway. In addition, you can create special equipment of the desired size, degree of adhesion to the ground, as well as performance.
As for the disadvantages, they are that hand-made equipment is much inferior to factory models in the level of reliability. Also, such a technique often requires repair work.
A wheel kit for converting special equipment into a mini tractor should consist of four wheels with a diameter of 12-14 inches.
If you install wheels with smaller dimensions, then the mini tractor will bury itself in the ground while driving, and in the opposite case, the control will become more complicated.
Instructions for assembling a mini tractor from a walk-behind tractor
Those who are interested in how to make a mini-tractor from a Neva, Forte walk-behind tractor or from Zubr equipment, you need to know that the manufacturer does not really matter, this does not affect the efficiency of the tractor. The main thing is to correctly develop a drawing and a construction scheme. Also, the owner of the equipment can use ready-made developments.
Frame and body
To build the frame, it is allowed to use metal pipes and corners. Bolts should be used as fasteners, but welding will be required to create a strong connection.
A mini tractor with your own hands can be equipped with a body. This will give the equipment not only a presentable look, but also protect the components from dust, mechanical and climatic influences. In this case, stainless steel sheets are used.
Operator’s seat and steering gear
After completing the manufacture of the frame with a body for homemade equipment, the operator’s seat should be attached to the structure. Here you can use the driver’s seat from any vehicle. It must be installed in such a way that the driver can easily adjust himself to the position of the seat. the height and angle of inclination. The steering wheel is created according to the principle of building the installation in karting. But here you need to strengthen and shorten the traction.
