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.
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.
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.
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.
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.

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.
Required materials and tools
To assemble a mini tractor from a walk-behind tractor with your own hands, you will need:
- rolled metal to make a welded frame (square, channel, corner, and so on);
- wheelset (with one-piece axle or 2 semi-axles);
- wheel bearings;
- seat of suitable dimensions;
- hardware for assembly (nuts, studs, bolts);
- consumables for welding operations. gas, oxygen, wire, electrodes;
- primer, paint for painting the assembled product.
Required parts for making a mini-tractor
To carry out the work, you will also need a certain tool:
- locksmith. hammer, chisel, keys;
- welding machine for work on the assembly of the frame;
- gas cutting kit, if necessary;
- angle grinder for cutting, grinding metal elements;
- electric drill with a set of drills;
- taps and dies;
- devices for carrying out painting and anti-corrosion protection.
Turning equipment may also be required. for working with a wheelset.
Design features of the minitractor
As already mentioned, you can purchase a ready-made module with wheels and a seat, or you can assemble all these elements yourself. In the latter case, a simple design is created without a drive for the 2nd wheel pair and without a full-fledged steering column. The additions in the form of an all-wheel drive and a steering column do not provide obvious advantages during operation, but they significantly complicate the assembly process.
The homemade mini-tractor is controlled by turning the entire transmission-motor unit, for which a standard steering wheel is used. a single-axle tractor is complemented by a hinged module, with a seat and a hitch for trailed devices (for earthwork). In order to implement this low-cost, simple option, a frame made of rolled metal with a wheelset is assembled. A seat and 2 trailer units are mounted on it. for attaching to a walk-behind tractor, for attaching transport or tillage accessories.
Mini-tractor based on the Neva walk-behind tractor
Working on a personal plot is, first of all, hard work, and then also the pleasure of the result. Many people strive to mechanize heavy operations, for which walk-behind tractors, mini tractors, cultivators are purchased. The most popular technique is considered to be a single-axle tractor due to its low cost.
the single-axle tractor “Neva” can be easily converted into a mini-tractor with your own hands. to make the assembly of the new device easy, a special adapter equipped with a seat is purchased. This adaptation will allow you to quickly change your single axle tractor. It is needed for the simple reason that the Neva is a structure designed for field work on foot, but a mini-tractor based on a walk-behind tractor is much more comfortable, since the driver is seated.
A homemade mini-tractor from a walk-behind tractor is a great device for work.
How to remake a single-axle tractor Neva
There is a standard step-by-step upgrade process:
First of all, when answering the question of how to make a mini-tractor from a walk-behind tractor, a kinematic diagram should be developed. In it, be sure to take into account the balance of the structure, otherwise future unbalanced loads can destroy the device. The scheme (and general design drawings) is developed independently, or you can use a typical kinematic image of a minitractor. It consists of an engine, front and rear axle, reverse gear, chain and cardan gear. The engine makes the front wheels spin. The torque is also transmitted through a chain, a reverse gear, a cardan transmission to the rear axle, as a result of which the rear wheels rotate (they are driving).

DIY mini tractor from a walk-behind tractor!
Many often ask the question: how to make a more functional and easy-to-use unit out of your walk-behind tractor? The specialists of our service center will try to explain all the nuances of converting a walk-behind tractor into a motor-tractor, but first, let’s figure out what a single-axle tractor is.
Motoblocks, which are essentially light two-wheeled tractors, have become excellent helpers for the villagers. With their help, they cultivate the land, plant and harvest potatoes, harvest hay, transport goods, and in winter they clear snow. These functional units have an affordable cost and many advantages, but they have one serious disadvantage, difficult operation for a beginner and tedious work for a specialist. In response to this problem, from the beginning, enthusiasts, and then industrial enterprises, began to produce kits for converting motoblocks into tractors.
At the moment, there are several types of whale kits on the market, they are different in design and are designed for different types of motoblocks. For an uninitiated person, it is quite difficult to figure it out, so we decided to write an article that will help in choosing. To begin with, just look at the needs of buyers and identify the foundations for choosing, and then we will consider technical solutions for converting a walk-behind tractor into a tractor. There are two types of walk-behind tractors, with an air-cooled engine and a water-cooled engine, respectively, and the kit must be selected for the type of walk-behind tractor.
To simplify the group of light motoblocks, we will present models from the Forte company, since it is they who are most often converted into a motorcycle tractor. The easiest way is to buy a towing adapter. It is suitable for both light and heavy motoblocks, this is the most affordable way to get your single-axle tractor with four wheels. Such an adapter is attached to the back of the walk-behind tractor through a trailing unit, turns are carried out using the handles of the walk-behind tractor due to the hinge located in the area of connection of the adapter with the walk-behind tractor.
The main drawback of such an adapter is the impossibility of using attachments that require a drive, therefore such an assembly can hardly be called a full-fledged motorized tractor.
Adapters with a steering wheel will be more functional, they can be divided into three types:
- rear adapters without propeller shaft
- rear adapter with propeller shaft
- front adapter
The simplest and most affordable solution for light motoblocks is to buy a front adapter with a steering wheel. Rear-mounted motor and gearbox allow for driven attachments
KIT kits for converting a heavy walk-behind tractor into a mini tractor.
Conversion kits for heavy motoblocks are divided into 2 groups.
- KIT with natural gearbox position.
- KIT with deployed gearbox.
A kit for heavy motoblocks, in which the gearbox is in a natural position, in fact, when converted into a motorcycle tractor, the box is simply rolled into the frame. Our experts note such advantages in this design, a flat plane under the seat, a convenient gearbox movement, the milling cutter is connected to the fasteners provided by the factory, as well as the possibility of converting it back into a uniaxial tractor. In our opinion, the disadvantage of this design is the low lifting capacity of the lifting mechanism, which is very important for a motorcycle tractor.
A whale set and with an unfolded gearbox, as an example, we will examine a set produced by Chp Kryuchkov, when reworked, the box turns. The advantage of this design is the versatile rear lift with high lifting capacity and the ergonomic position of the gear lever. The disadvantage of such a construct is a relatively complex cutter drive mechanism.
Despite the availability of various options, there is another important factor in the choice, this is the quality of workmanship and the general thoughtfulness of the design, when choosing a particular kit, this is a decisive factor when buying a kit for converting a walk-behind tractor into a motor-tractor. For those who have not quite figured out the kits for converting a walk-behind tractor into a tractor, we suggest you get acquainted with the video, we would also be very interested to know your opinion about each type of whale kits. Share your opinions under the video, give recommendations if we missed a certain type from the field of view, and also ask your questions.
