Farmer adapter for converting a Moto-Block into a mini-tractor
How to make a minitractor from a walking tractor: step by step instructions
For owners of land, indisputably, a minitractor is a more desirable purchase than a single-axle tractor, because it is many times more powerful and comfortable. But, unfortunately, not everyone and not always manages to get just this machine, citing its cost, size and a number of possible reasons.
But if you already have at your disposal such equipment as a single-axle tractor, you can easily convert it into a mini-tractor with their own hands. For this you will need some tools, materials and desire.
A mini tractor from a power tiller with your own hands. how to make
Before you start making a mini-tractor on the basis of the tiller, you need to prepare the necessary materials for the work. The conversion kit includes:
- Welding machine;
- Screwdrivers and wrenches;
- An electric drill and a set of various drills;
- angle grinder and a set of discs for working with metal;
- set of nuts and bolts.
Properly assemble a tractor from a power tiller will help the appropriate drawings. In them you will find information on what order to connect the parts and what method of fastening is suitable for their reliable installation.
The modification of the power tiller into a minitractor is performed in the following order:
- The minitractor based on the power tiller must necessarily be equipped with a strong reliable frame. It must be able to withstand an extra pair of wheels, plus the load carried in the tractor will be pressing on the supporting structure. Tubes or metal corners are best for making a sturdy frame. Be sure to note that the heavier the frame, the better will be the traction of the mini-tractor with the road, and the better will be the plowing of the ground. frame wall thicknesses are also of little importance. the main thing is that they should not bend under the pressure of the transported material, and the frame blanks can be cut with an angle grinder. Then all parts are bolted together and finally welded together. To make the frame stronger and more reliable, equip it with a crossbar;
- Immediately after the frame is made, it can be equipped with an attached mechanism, which will equip the small tractor with additional devices. You can install the hinge both in the front and in the back of the supporting structure. If in the future the manufactured mini-tractor is planned to be used with a trailer, then a tow bar should be welded to the back of its frame;
- The next step is to equip the self-made car with front wheels. For this purpose, it is best to equip the mini-tractor you are making with two prefabricated hubs with brakes provided on them. Next you need to secure the wheels themselves. To do this, take a section of steel pipe whose diameter fits the front axle. Next, attach the wheel hubs to the tube. Drill a hole in the central part of the tube, which is necessary to mount the product to the front of the frame. Then install the steering rods and adjust them to the frame by means of a worm gear. After installing the gearbox, mount the steering column. The axle at the rear of the tractor being made is mounted through pressed bearing sleeves. The wheels used must be no more than 15 inches in diameter. Parts smaller in size will lead to “burying” the machine front end, and the wheels, the size larger, will significantly impair the maneuverability of the mini-tractor;
- The next step is to equip the mini-tractor with an engine from a power tiller. It is best to mount the motor at the front of the machine, as this way you will improve the balance of the farm machine when operating with a loaded trailer. Fit the motor in a secure mounting system. When mounting the motor do not forget that the PTO shaft should be fixed coaxially to the pulley, located on the rear axle of the mini-tractor. The power to the wheels must be transmitted by a belt drive. For more details on how to convert a power tiller into a mini-tractor video.
Makeshift tractor will be equipped with a reliable braking system and quality hydrovalve, which is necessary for the trouble-free operation of the unit with attachments.

How to make their own hands
Of course, the purchase of an adapter to the power tiller, ready to work. is the best and easiest way out of the situation. With all that they are really quite a lot, so not every farmer or just a cottager is willing to afford their purchase. No wonder why many people wonder how to make an adapter with their own hands.
It is certainly possible, and you can find quite a few recommendations on the web, which relate to the self-made adapters. over, there are many drawings that give the opportunity to consider this device more clearly and in detail.
Using them, it is quite possible to create such a unit in domestic conditions, using a minimum of tools and materials. To make a homemade adapter will need:
- welding machine;
- wheel set;
- steel angles and sheets;
- driver’s seat;
- fasteners; iron pipes.
The whole work will consist of several steps:
- We take a square metal profile, about 1800mm long. Cross it by welding the same iron flap, only smaller, about 600mm. To this web of the profile the wheel stands, the height of which should be about 300 mm, are fixed later on.
- After that you need to attach the struts. They are attached to the center frame and to the wheels. The angle of wheel bushings in relation to the frame can be whatever you want. To the metal profile additionally weld a beam. This is necessary to reinforce the frame.
- Frame for additional equipment is welded from channel 0.
- It is aligned to the wheel axle by means of a piece of square tube, and the seams are welded by means of a welding machine.
- Now, to the frame welded control lever with three knees (200, 350 550 and millimeters).
- Let’s fasten one more (size 800 mm) to the lever, it will regulate the force.
- Bolt the arms together with ordinary bolts.
The first step is complete. Proceed to the next.
Work with the construction of the adapter
Now start working with the adapter. To do this, perform the following steps:
- To the central frame you need to weld a piece of 300mm tube, that will be a support for the driver’s seat.
- From above, perpendicular to this stand, similarly weld 2 pieces of pipe. This is required so that the seat does not come off during the work and is more stable in the process of shaking when working. The seat can be ready-made, and you can make it yourself from a piece of plywood and foam rubber, it’s at the discretion of the master.
- Fix the seat to the cross pieces of pipe that are welded to the stand itself, as well as to the stand under the seat. Use bolts as a fixing element.
- At the front of the coupling mechanism is welded to the power tiller, after that the work can be considered as finished.
Adapter with steering control
If you have the skills, then if you want the design can be a bit more complicated, making another makeshift adaptor to the tiller, to which you can attach more and steering control.
To implement this idea, you will need to prepare the following materials and tools:
This construction requires the frame adapter to be firmly connected to the tractor unit, otherwise the device will be, as they say, “led sideways”. For the design, you can take any ready-made steering wheel, even from old “soviet” cars (from the same from VAZ, for example).
Adapters for any power tiller, including the Neva, provide an opportunity to significantly increase operator comfort in controlling the mini-tractor. In fact, the driver no longer has to constantly drag behind the machine. Now he can just sit in a comfortable seat and do the same thing, but with comfort and more warmth.
The design of such units is quite simple, and independent production of them at home is quite possible. Here we should take into account that home assembly presupposes at least basic skills in welding, as well as the accompanying tools. You will also need to stock up on a large number of corners and metal pipes, so as not to stop work due to lack of material. In general, the expediency of the proper assembly of the adapter, especially considering that it saves a lot of money.
How to make a mini-tractor from a power tiller with your own hands
Every farmer knows that it is easier and more convenient to work on garden plots with a small tractor. And do not worry if you do not have enough money to buy the factory “iron horse”. you can make it yourself from an inexpensive motor block. All the more, when there is interest in technology, engineering abilities, the necessary equipment and tools, it will be absolutely not difficult to do it. The main thing is to understand the technical aspects, prepare for the transformation and correctly choose the single-axle tractor itself. Then you can start converting. By the way, the manual of the motor block may contain a drawing, which will help to understand how best to make a homemade.
Features of designs
Re-equipment of a power tiller into a minitractor does not require the owner to prepare technical documentation and registration of the vehicle in the bodies of the traffic police. A common feature for homemade structures is the frame, on which the power unit, rear axle and control units are rigidly installed. When assembling the tractor use ready assemblies from serial cars and tractors.
For those who want to save time, there are ready-made kits for converting a power tiller into a mini-tractor.
An example would be the Crosser equipment conversion kit with an average
There are more affordable kits, which are made by small workshops. The kits include the frame, actuators and brake mechanism, fenders, as well as the seat and steering trapezium. The advantage of such a set is its versatility. the customer can adapt it to the existing single axle tractor in accordance with his preferences.
The standard power units are four-stroke carbureted engines with a cylinder volume of up to 250 cm³ and developing up to 10-13 liters.с. Less common are diesels with similar characteristics. Gearboxes have up to four speeds and are connected to the drive wheels by belt drives. Gear or chain drives are used in wheel drive. Standard transmissions often lack a differential.
An additional pair of wheels mounted on the mini-tractor can be used for directional control. Theoretically it can be equipped with a drive, but the transmission scheme would be more complicated. To realize all-wheel drive requires application of constant velocity joints on driven wheels and differential. Otherwise the all-wheel drive will impair cross-country ability and reduce reliability of the transmission.
Depending on the intended use of the mini-tractor frame scheme is selected. If the tractor is used for tillage or other agricultural work, the closed rectangular steel frame is optimal. The frame must be strong enough to withstand the weight of the tractor mechanisms as well as the loads occurring during the work.
If the mini-tractor is to be used as a means of transport, it is recommended to use a two-part broken frame. Elements of the frame are connected to each other by a swivel joint. The transmission becomes a challenge in such a design. To transmit the torque to the drive wheels it is necessary to use PTO shaft or place the engine together with drive wheels on one part of the frame. The second variant is simpler, but does not provide uniform loading of the tractor wheels.
It is possible to install cross bars for the rear hitch of auxiliary agricultural equipment. Readymade adapters or homemade units, created with the specifics of the trailer, are used for towing trailers.
The first thing, proceeding to the study of the drawings, it is necessary to decide for what functions the mini-tractor will be used: what will be more included in its tasks. agricultural work or transportation of goods. This is what determines the final design. Note that many users give preference to universal designs, allowing both to work with agricultural attachments, and to transport weights in the trailer. Therefore, universal drawings are most often appropriate.
By the way, if there is no trailer in the farm, it can also be assembled with your own hands if you wish, since the design is not very different from the mini-tractor. And since the selection of materials, which will become components in any case, you can make a mini-tractor and trailer at the same time. It is only important that all selected parts fit well together.This is interesting: a self-made mini tractor from MTZ power tiller.
To ensure the correct operation and high reliability of the device, it is recommended to draw a diagram of the future tractor in advance. On it you should draw the connection points between the axle and the gearbox shaft. It also makes sense to provide reverse drive to improve the cross-country ability and maneuverability of the mini-tractor. And it is necessary to think through the design of the rotary device. Once its design is chosen, you can proceed to the assembly.
Drawings, diagrams, detailing, assembly
First of all, it is necessary to understand what the single-axle tractor will mainly be used for. For agricultural work with soil or for transportation of various objects. often they choose a universal model to work in the garden and to carry loads around the house. On the back of the minitractor is added a towbar for hitching to a trailer. Which, if desired, can also be assembled according to ready-made diagrams, because the materials for making a mini-tractor and trailer are similar and you can make two models at once.
In order for everything to work quickly and correctly it’s necessary to make a kinematic scheme.
This drawing shows where the wheel axle and gear shaft are connected. It is recommended to install a rear drive. This will give the mini-tractor extra stability and passability.
Choose all parts carefully. They have to fit together. If necessary, they can be adjusted using a lathe. How well the components fit together will determine how long the mini-tractor will work.
When the drawing is made, it is necessary to take into account the turning device. It can be in two variants:
- Turning with body fracture is a rugged, reliable and time-tested design. But it is not particularly maneuverable when making turns. And the steering column is mounted well above the joint.
- The steering linkage is a more maneuverable version of the mini-tractor control. It allows you to make turns at high angles. But this version also needs more parts. It is best to use factory parts from other vehicles. The advantage of this option is also the fact that both rear and front wheels of the mini-tractor can be driving.
After selecting the turning device, you can proceed to the conversion of the power tiller into a mini-tractor.
The process of creating the frame
For independent creation of the frame you need a small amount of materials, if any of the components are not available, they can be replaced by analogues. But at the same time they must have similar dimensions and properties:
- Metal for the frame. you will need angles, channel bars and square tube. For the shell, you need to use steel that is more than 1.5 mm thick.
- Swivel head
- A pair of wheels and axles for them
- Bearing assembly
- Tools (tape measure, welding, drill and angle grinder)
Carefully observing the initial diagram, the frame is assembled. According to the dimensions, connection angles and kinematic diagram.
Check that all components are correctly assembled after connection. To do this, mount the frame on the single axle tractor. If everything is in place, we begin the next step, if anything is not installed, it is corrected and installed again.
Further, the ready elements are installed: a steering rod (which is best to be installed on the rear axle), hubs and the axle. The wheels are attached to the axle with bolts.
At this point the assembly process is complete. And you can start test runs. Here it is necessary to drive the mini-tractor on a flat surface.
It is often necessary to further adjust the steering or the positioning of the wheels.
If all is well, then you can connect the attachment and begin the field test. If desired, you can also carry out cosmetic work with paint or primer. This will protect the mini-tractor from the effects of corrosion.
The video presents a slide show. how to make a mini-tractor from a power tiller:
The process of converting a power tiller into a mini-tractor by yourself is a rather laborious task, and many people do not see the point in it.
over, for power tillers Neva “Red October” offers a ready-made design. an adapter. And there is no need to perform all these manipulations.
But it’s not that simple. The adapter is good only if minor operations are required. It does not have reliable grip mechanisms. And with uneven surfaces or sticky soil, it will constantly slip. With a minitractor no such problems arise, so the single-axle tractor Neva with adapters minitractor will not replace us.
We make a mini-tractor from the motor-block “Neva” with our own hands
Making a minitractor from the motor block “Neva” with your own hands, you will minimize the time and effort, which will result in an excellent device to do all the work on the homestead plot. Additionally to the adapter you can buy: a plough, ridger, harrow and other attachments.
You can also upgrade a single axle tractor into a mini tractor with your own hands from unused parts of other equipment. This re-equipment option will take more time, but it will pay off inexpensively.
To create a mini-tractor from the “Neva” power tiller, you will need the following components: the single-axle tractor itself, metal pipes, angles, sheets, two wheels, a welding machine, a seat for the driver, a set of tools.
Step by step process of upgrading a power tiller into a mini-tractor
Developing the construction of the kinematic scheme. The main thing in this scheme is the equilibrium of the structure, so that additional loads will not destroy the future equipment. This scheme is developed independently, or you can use a ready-made scheme, with a kinematic image of the mini-tractor. We make a frame from angles and pipes
When making the frame, it is important to think about the location of the fork and bushing, which ensure the rotation of the trailer. Making the body
Steel plate is a good material for the body. The height of the sides of the body should not exceed 30 cm. We install the driver’s seat. Mounting attachments. Check the workability of the manufactured mini-tractor. Painting.
One of these options, to create a mini-tractor, we will consider the example of the power tiller “Neva MB-2s 7,0 PRO”. The engine Subaru EX 21D is installed on this crawler tractor. If you plow a garden plot with this tractor, it will be difficult to straighten up within a week. In order to avoid such consequences, we convert the single-axle tractor into a mini-tractor.
Since SUBARU engine has no 12v output, the headlights are installed for decoration. To engage them, you need to install a battery pack or a battery. When plowing the land, you do not notice the imperfection and inconvenience of this technique. This mini-tractor was tested on heavy soil for plowing. Although the traction characteristics of the tractor were questioned when it was built, the tests were very successful.
Also a big plus of this machine is that the driver and the front of the mini-tractor are an additional load, which helps the drive wheels grip the ground better. Levers installed: throttle lever on the right, half axle release lever on the left. Sprocket, 150 mm in diameter, is used for lifting. Hauled with a bicycle chain to a lever or a manual jack.
Installed wheels from Volga, found on the dump, preliminarily cleaned from rust and painted. Pedal layout similar to the car pedals: right pedal is brake, left pedal is clutch. Speeds are changed with the lever. Brake pads, taken from “Riga-7” moped, are installed.
The principle of clutch pedal operation is the same as that of a power tiller: when depressed, the mini-tractor drives, if released. it stops. To the left armrest lever is a cable that unlocks the axles. It is used when it is necessary to turn. No special nuances when turning right or left. The right armrest houses the throttle lever. The linkage lift lever is located under the seat.
Belt wear on gearbox is the same as on a power tiller. The sum of driver and front weights equals 100-110 kg, which prevents the front of the tractor from lifting when ploughing. The size of the cultivated track is the same as the power tillage track. 630 mm. Problems with stability arise if the plow goes deeper than 20 cm.
Consumables, parts and spare parts needed
To understand what components are needed to build a machine, you need to know what components are included. This is an important aspect that allows you to buy the right elements at once and will avoid unnecessary costs.
- The frame. made of any kind of metal;
- device for turning;
- Metal, necessary for body cladding;
- hitch. helps to connect other equipment.
These components are not difficult to buy: there are many of them in car breakdown places or at the scrap metal recycling point. But the choice of these components should be approached responsibly. Often they are no longer new, so you need to carefully inspect them for damage. In the case of defects, the homemade unit will not work properly.
drawings and assembly
To make a mini-tractor from a power tiller with engine with your own hands, you need to prepare drawings and assembly diagrams in advance. You can work on it yourself, but you must meet the main condition. there must be a balance to avoid unpleasant “surprises” in the work of the machine.
Creation of the frame
To create a framework, you do not need a lot of material. In this case, if something is missing, you can use analogues. But the dimensions and properties should be similar. We are talking about:
- If you work with metal, you need to prepare the square-shaped angles, channels, and tuba. You will need at least 1.5 mm thick steel for the cladding;
- wheels and axles;
- tape measure, welding, drill, angle grinder.
Assembly is carried out only according to the scheme. you can not deviate from it.
Once all the elements have been connected, you need to check whether the installation has been carried out correctly. To do this, you need to install the frame on a single-axle tractor. If everything is as it should be, then you can continue to create a mini-tractor. If something has gone wrong, you need to fix the flaws.
Recommendations for converting a power tiller into a mini-tractor
How to choose a seat and wheels?
Choosing a seat for the minitractor, you should pay attention to its dimensions. The seat should be so that it is comfortable to sit and work in. Self-made minitractor is best equipped with a seat from a passenger car, as it can be easily adjusted. Seats from old cars that you can find at salvage yards are ideal.
Another important point in the process of converting a power tiller into a mini-tractor is to determine the height of the steering wheel. After completing the installation of the driver’s seat, you should sit in it, taking the position in which you will be during plowing on the mini-tractor. This will show you how high the handlebar is best. Make a tractor out of a power tiller easy to operate by making the steering wheel easily accessible for your hands. The main thing is that it should not interfere with the free positioning of the knees.
Choosing a kit for converting your power tiller, it is important to consider the wheels carefully. Wheels from old cars are quite suitable. When choosing the optimal size of the wheel disc, it is better to give preference to the wheels 12. 14 inches. They are installed in the front axle of the minitractor. A four-wheel drive mini-tractor sometimes includes a rear axle with larger wheels than the front axle. Smaller front wheels can cause the single axle tractor to dig its nose into the ground.
Correct wheel size for the front axle allows you to avoid heavy steering, otherwise you will only be able to turn the steering wheel with effort. Choose tires that are designed only for mini-tractors. Using a homemade mini tractor is also possible in the dark with clearance lights and headlights. If necessary, additional details of cladding are installed on the converted equipment.
Can a single axle tractor turn into a tractor?
The kit for converting a Moto-Block into a tractor, of course, consists of spare parts that are missing in the Moto-Block.
What type of power tillers will work?
Internal combustion engines on power tillers replace 8-10 horses, the minimum acceptable power of a tractor. 10-11 liters.с.
Gasoline engines are rejected at once. Yes, there are mini-tractors with these engines, but this equipment is not for agriculture, but for gardening and landscaping.
The brand of power tiller is not important. The requirements for it. water-cooled diesel engine with an electric starter. A single-axle tractor with this set of features turns into a mini-tractor. Question: can it be called a complete? In the course of the dismantling we will find out.
In the GADENSHOP shops, where the presale preparation of mini-tractors takes place, we made a little experiment. Assembled a mini-tractor with a conversion kit.
The Big Scam
We do get a lot of requests for these kits. So we decided to find them from suppliers and found out that they are impossible to buy for the stated price. several tens of thousands. Because of surcharges and customs duties the price rises to the cost of a whole power tiller. It turns out that the converted mini-tractor is equal in price to two power tillers.
We found this kit with great difficulty and for the mentioned price. Now let’s demonstrate what this set includes.
So, in the basic kit for converting a power tiller into a mini-tractor.
Bearing frame construction, in fact, is a reduced copy of the frame of “Centaur”, “Uralts” or Xingtai XT-220. but with much lower quality of metal and welding. The landing place with a support is not too comfortable, the distance to the steering wheel is short.
A tractor turns out a belt, so you need a protective cover to cover the transmission mechanism. Otherwise the mini-tractor will be traumatic. Wheel fenders; levers that lock the half axle; brake cylinder; brake fluid reservoir; brake drum complete with support disc; rear lift mechanism; and a soil tiller mounting kit;
- A set of fasteners (nuts, washers, etc.)
- Socket and socket wrenches
- Screwdrivers and a hammer
- The drill
- angle grinder
- Welding machine;
- angle grinder;
- Clamps; circles and drills on metal;
What are the characteristics of the tractor
When you assemble the machine from the resulting spare parts, you want it to be as heavy as possible.
We are not talking about the materials that would be necessary if we had to build the missing parts of the frame structure ourselves. Fortunately, there is no shortage of offers on the purchase of ready-made kits. Complete kits If you have a diesel single axle tractor, but you are not satisfied with its performance, you can easily convert it to a full-fledged mini tractor. Kit for converting a power tiller into a mini tractor,. designed for Crosser CR-M 8 series power tillers. Much easier and more profitable to buy a mini-tractor.

Preparing the tools and kit
Beginning the conversion of a mini-tractor from a power tiller with your own hands, you should think about the position of the engine. If the power unit will be behind the driver’s seat, this installation will be more acceptable. This ensures the creation of a more secure grip of the drive wheels on the ground. The weight of the driver, which will increase the additional pressure on the front axle simultaneously with the power unit, will not allow the machine to tip back when carrying out arable work on hard ground.
Together with the drawings, kinematic diagrams are also needed to make a correct calculation of the load on the frame. At the same time, the diagrams allow you to make a calculation of the traction force that is needed to perform all the work on the homestead. Modification of a power tiller into a minitractor begins directly with the preparation of all necessary tools:
- Welding machine.
- Electric drill or boring machine.
- angle grinder.
- Socket wrench and socket wrench set.
- Metal cutting discs.
- Disks for angle grinder, electrodes, a set of drills for metal.
- Bolts, nuts, washers.
- Screwdriver set.
Materials, including the main nodes and elements that will be required to create a homemade tractor from a power tiller, may be as follows:
- Steering wheel.
- Wheels (4 pcs.).
- Front wheel hubs with brake system.
- Driver’s seat and its base.
- Metal profile pipes for frame and supporting structures.
- Steering rod.
- Footboard with pedals.
- Steering rods.
- Steering worm gear.
- Fluid tank (brake fluid).
- Fenders (to protect wheels).
- Brake cylinder.
The elements of this kit, that is, kit-set, are designed to simplify a large number of different works in the garden or in the garden. Before starting to re-equip a walking tractor with a walking tractor, all of the missing parts should be bought ready-made or installed with your own hands.
The use of the kit for converting the power tiller into a minitractor will make it possible to use the elements of the ready-made device in a complete set, which will provide more opportunities when working with the minitractor.
Principle of converting a power tiller into a mini-tractor
Start remaking a mini-tractor on the basis of a power tiller usually with making the frame. It must be metal. You will need to cut the metal, which has been prepared in advance, into separate pieces of the desired length. These are bolted together with electric welding or with bolts. After assembling the frame, you can begin assembling the running gear. Assembling a tractor from a power tiller with his own hands, it is necessary to provide for the width of the track depending on the location of the power unit, which can be behind or in front.
If the engine will be located in the front of the machine, then the track width should be determined by the base wheels of the motoblock. Remaking a single-axle tractor into a mini tractor, the rear wheels are attached to the frame using an additional axle. It can be made of a pipe of a certain width. On the ends of the tube there must be pressed bushings fitted with bearings. Assembling a minitractor from a power tiller with their own hands, the wheels are installed on them at the last stage of assembly.
If the homemade minitractor will have the engine located at the back, the track width is usually widened. Otherwise, the necessary machine balance will not be provided. Beforehand, it is necessary to take the base wheels off the power tiller and install them on the wider axle. Assembly is carried out in the same way as in the variant with the location of the engine in the front. Self-made mini-tractor from a power tiller must have grousers, allowing you to improve the traction of the unit with the soil.
Steering can be a handle from a power tiller. In this case, the mini-tractor will resemble a motorcycle. When driving in reverse, this type of control will cause a lot of inconvenience. Remaking a mini-tractor from a power tiller, it is better to install a conventional steering column on it. It will make driving in reverse more comfortable. Installation of the driver’s seat is carried out on skids, which are welded to the frame.
All-wheel drive mini-tractor, made with their own hands, has good characteristics of the bottom, which allows you to perform almost the same amount of work as the analogues in the workshop, such as Uralets, Kubota, Bulat 120, Yanmar, Belarus. 132n, a scout.
Of course, the power of the homemade unit may be slightly weaker, but at the level of home use this fact is hardly noticeable.
Area of application
The main area of application of this unit with their own hands is agricultural work. The term covers a fairly broad range, including many related works. In other words, a homemade mini-tractor is needed for the following purposes:
- Plowing plots of land for their further use;
- Tilling the soil, as well as getting rid of weeds;
- tearing up the ground;
- sowing on tilled soil;
- planting and digging potatoes.
In principle, this is the main purpose of the minitractor, for which it is created. However, its use can be significantly expanded, if its design provides a special connection for additional, attached and trailed equipment.
If everything is done correctly, your homemade tractor will be able to do such work as well:
- transporting various loads (transportation of firewood, construction debris, etc.);
- snow removal in the winter;
- mowing meadows and lawns and making hay for livestock.
As we can see, a mini-tractor breaking the classic 4×4 with their own hands can significantly ease the life of any villager, because with the help of this technique it becomes possible to perform all kinds of work that is required for the competent maintenance of the subsidiary farm.
The indispensability of a homemade unit is also due to the fact that in its manufacture uses a minimum of investment and funds, which is very important for the countryside.

How to assemble the mini-tractor with their own hands
Having prepared diagrams and drawings, it is necessary to find suitable parts. At a minimum, you will need an engine, transmission, chassis and steering. Finding the right parts at home is very problematic, so you can wander through the flea markets and go to sites where parts are sold. Here you can literally buy the right parts for pennies.
The fracture is usually made or n. 9. The structure of this material has a sufficient margin of bending strength. Two half-frames are welded together with a hinged joint. For this purpose, you can use the driveshafts of trucks.
If you are not satisfied with the fracture, you can make a mini-tractor on an all-metal frame. Such a design usually consists of four elements: right and left side members, front and rear crossbars.
Longitudinal members can be made of channel n. 10, rear and front cross members from channel n. 16 and n. 12 respectively. A metal bar can be used as a cross-beam.
To work with the mini-tractor with their own hands can be equipped with any engine of suitable capacity. Optimal option. power unit with 40 horsepower.
Most often, the engines M-67, MT-9, UD-2 and UD-4 are installed on homemade units. There are models equipped with engines of domestic cars series “Zhiguli” or “Moskvich”.
If the domestic product is made on the 4×4 formula, the M-67 unit will need to increase the transmission ratio, otherwise the power unit will not have enough power to provide the necessary strength of the wheelsets
Please note that an additional cooling system may be required for the transmission
Gearbox and PTO can be removed from a GAZ-53. The clutch will fit to an old GAZ-52. These nodes will not work in the finished state; further adjustments will be required.
To synchronize the clutch with the engine will need to weld a new clutch basket and fit it to the required size. The engine flywheel will need to shorten the back plane and drill an extra hole in the center. These operations can be performed on a lathe.
Assembling a mini-tractor
This unit should include hydraulic cylinders, it will provide better controllability of the mini-tractor. It is impossible to make plumbing with your own hands at home. That’s why it is necessary to remove ready-made plumbing from any agricultural machinery. Note that a pump is required to circulate oil in the hydraulic system.
You can take a suitable assembly from a car and truck and install it on a homemade structure. You need to shorten the drive shafts on a lathe beforehand.
If there is no ready-made axle, a composite construction from different machines is allowed. The front axle is not a drive axle, so any unit of suitable size will do.
The radius of the wheels depends on how you will use a mini-tractor. Rims with a radius of 13 to 16 inches are best for hauling. For agricultural work, you will need wheels with a radius of 18-24.
To make a mini-tractor at home, you do not need to turn to professionals. Just choose a scheme and a drawing, buy the necessary spare parts and get to work. You can also find instructions now, where each step is captured on the photo.
