The minitractor is an indispensable agricultural equipment for cultivating the land, planting seeds and harvesting. Especially this technique is in demand in the village, among the owners of large household plots. The cost of mini tractors in the factory version is quite high. Even the latest Chinese-made technology is sometimes not affordable for everyone. Therefore, more and more home craftsmen are trying to make a mini tractor on their own, using improvised materials.
If you decide to assemble a mini tractor with your own hands, then first of all you need to pick up power unit. The latter is often used ZID engine. This is a four-stroke unit with a volume of 0.52 liters. and a capacity of 4.5 l / s, which is quite suitable for processing 2-3 hectares of land. The engine is easy to maintain, so it is often installed on various home-made equipment, moreover, it is easy to buy it on the Internet.
Another option for homemade is . This is a two-cylinder unit with a capacity of about 12 l / s and a volume of 0.42 liters. Although this type of motor has long been discontinued, there are a large number of offers on the Internet for the sale of this unit. It can be bought for approximately 5,000 - 8,000 rubles.
Often, in the manufacture of homemade tractors, craftsmen use motors from cars. For example, you can meet mini tractors with an Oka engine.
This engine has a power of 29.3 l / s and a volume of 0.649 liters. In fact, this is a VAZ engine (VAZ 21083), only in a lightweight version, since it has 2 times less weight. A distinctive feature of the engine from the Oka is its low gas consumption and high efficiency.
The more expensive option is engine from "Zhiguli". The motors of the VAZ car line have an engine power of 59 l / s (VAZ 2101) and higher. A tractor with a VAZ engine is a fairly powerful unit that can cope with almost any agricultural work.
Owners of walk-behind tractors to make a mini tractor for household the easiest way, since this unit already has all the necessary control nodes. It remains only to make a suitable frame, and the tractor is ready.
What to make a frame
The assembly of a mini tractor always begins with the manufacture of the frame. The frame of the minitractor acts as a base on which all components and parts of this unit are fixed. The frame should be strong enough and at the same time not very heavy. It is usually made from metal corner, profile pipe or channel. Parts are connected by welding. The frame can be one-piece or two-piece.
one piece frame the easiest to make. It is enough to weld a rectangle from a channel or a corner. Frame dimensions are calculated based on the dimensions of the engine, gearbox and other components.
Also, 4x4 mini tractors are very popular among homeowners. These are four wheel drive tractors. with broken frame. The word "all-wheel drive" means that the unit is driven by both axles, front and rear. An example of such a frame made from channel No. 10 is shown in the following photo.
Frame fracture knot most often they are made from the cardan shaft of a car, for example, from GAZ-52.
The main advantage of a homemade tractor with a breaking frame is the small turning radius of the unit. Due to its high maneuverability, the fracture minitractor is successfully used in small areas where it will be difficult to turn a minitractor with a solid frame.
Below are drawings of a frame connected by a hinge.
What to make a chassis
To assemble a mini tractor, you need to prepare it undercarriage. It includes wheels, front and rear axles, transmission elements.
When choosing wheels for a mini tractor the intended use of the latter should be taken into account. If the unit is being built for the transport and pulling of goods, then a disk diameter of 16 inches will suffice. When using the tractor in the field, it is better to use more massive wheels with discs with a diameter of 18 to 24 inches.
If the drive axle in your tractor is only the rear, then front beam is made simple enough.
To make a homemade front axle, as well as its rear counterpart for all-wheel drive, you will need to take 2 identical chassis units, for example, from a VAZ or Moskvich car, and shorten them. How to shorten the bridge from a VAZ car can be found in this video.
Important! Bridges must have the same gearboxes, with the same gear ratio. Otherwise, front and rear wheels when the tractor is moving, they will rotate at different speeds.
Since the bridges already have a built-in mechanism for transmitting rotational motion to the wheel axle, it is not necessary to make a home-made gearbox.
Benefits of installing hydraulics
Hydraulics is installed on a minitractor in order to ensure the operation of some of its mechanisms and facilitate the management of this unit. The unit with installed hydraulics has its advantages.
- The car becomes easy to control. The steering wheel can be turned with almost no effort with one hand.
- Hydraulics makes it possible to use various attachments.
- The use of hydraulics allows you to upgrade the braking system. Thanks to the hydraulic cylinders installed on the unit, the braking of the unit occurs instantly.
You can make hydraulics on a mini tractor if you purchase a ready-made system in a store in advance or use parts from old agricultural machinery.
Important! When installing hydraulics on a mini tractor, it should be borne in mind that some of the engine power will be spent on servicing this unit. Therefore, for tractors with small engines installing hydraulics will not bring any benefit.
What is the VOM for?
The power take-off shaft (PTO) is designed to drive various agricultural mechanisms connected to a mini tractor, for example, various cutters for tillage, potato diggers, mowers, snow blowers, etc.
PTO can be like dependent and independent. In the first case, the shaft is driven by a transmission that transmits rotational motion to the wheels. As soon as the wheels stop, the PTO stops turning. An independent PTO receives rotation from crankshaft engine. Therefore, the higher the engine speed, the faster the shaft rotates.
In addition, there are tractors with PTO synchronous type. The speed of rotation of the synchronous shaft directly depends on gear ratio transmission of a moving tractor. Synchronization of movement and rotation is required when the unit is working with sowing equipment.
Making a three-point hitch
The hitch is used for tractor connections additional equipment , for example, a plow.
The hinge must be movable both in the horizontal plane and in the vertical. In the first case, mobility helps to reduce the overhang of the nozzle when taxiing. Vertical movement of the suspension is required to lower the equipment into service or raise it to the transport position.
A hitch on a minitractor is made from various parts taken from old agricultural machinery. Making a description of how to make a three-point hitch at home is quite difficult. Therefore, it would be more correct to use the following video, which indicates the dimensions of all parts of the device.
Selection and installation of brakes and clutch
Brakes must be installed on the rear wheelset. Easiest to take ready-made blocks from the UAZ car. The brake pads must be installed on the wheel disks, and the control should be brought to the pedal or lever installed inside the cab.
To install the clutch on a homemade mini tractor, you can also use a ready-made option from any car. For example, you can use belt clutch from Moskvich or UAZ.
The clutch unit is attached to the gearbox, also taken from any car. You can see how the clutch is installed in this video.
Steering installation
It is quite difficult to make a steering mechanism on your own, and in principle it makes no sense, since all the parts can be taken from any car.
When installing the steering mechanism, the steering shaft with gear is connected to the steering arms, which are available on knuckles installed on the front beam (the manufacture of the beam was discussed above).
How to make a cabin for a mini tractor
If in the summer it is possible to work on a minitractor even without a cab, then with the onset of the autumn-winter period, the use of the unit becomes rather uncomfortable or even impossible. Therefore, craftsmen try to assemble tractors with cabs in order to use this technique all year round.
Cabin for homemade technology make sheet steel according to a pre-prepared drawing. As a basis for calculations, you can take the cabin from MTZ tractor. The following photo shows a drawing, based on which you can make a cabin yourself.
Advice! If the cabin dimensions on the drawing do not fit the dimensions of your mini tractor, then they must be changed. But the main thing to consider when correcting sizes is the size. windshield and cab height. Its ceiling should be 25 cm higher than the head of a person sitting in the cabin.
The cabin is made as follows.
In general, in order to better understand how a mini tractor is made with your own hands, you can watch this video, a kind of beginner's guide.
The nuances of manufacturing a caterpillar tractor
Homemade tracked mini tractors are a technique, main feature which is high maneuverability and good maneuverability. Also, a tractor on tracks creates minimal pressure on the soil, which cannot be said about its wheeled counterpart.
To make a mini tractor on crawler, you will need the following design elements.
- Frame. It is made from a profile pipe or channel.
- Engine. For a tracked mini tractor, it is better to use a diesel engine.
- Main bridge. As in the manufacture of a wheeled tractor, a ready-made axle from an old car can also be used for a caterpillar unit, which should be shortened.
- Transmission. Ideal option there will be a box from GAZ-53.
- Clutch. A clutch unit from a GAZ-52 is suitable.
- Caterpillars. They are made from tires from the wheels of large-sized equipment, for example, from a tractor.
For making caterpillars you need to take 2 tires from the tractor and cut off the side parts on them. Then these tires are put on the wheels mounted on the frame, as shown in the next photo.
To make the tractor turn, on the rear axle you need to install a differential that will disconnect the right or left wheel from the drive. Also, each wheel must be equipped with a brake controlled separately. When you press the brake pedal and switch the differential, one wheel of the drive axle stops, while the opposite one continues to rotate. Due to this, the tractor turns in the right direction.
A mini tractor for the household is a very useful technique. With it, you can easily move and lift any loads, collect, for example, hay or cultivate a plot. At the same time, the range of possibilities of this technique can be significantly expanded; for this, it is enough to equip it with several additions. However, today we will not talk about attachments, but about how to make a mini-tractor for the household with your own hands.
Frame
This element is the most important and necessary for most pieces of special equipment (including such as a mini-tractor). Therefore, in order to avoid unpleasant consequences, it is necessary to draw up a drawing or diagram of the future design in advance. After that, you can safely proceed to its manufacture. For the frame, several lightweight metal channels should be selected and interconnected by automatic or semi-automatic welding. Also pay attention to the length of this element. The dimensions of the frame must be proportional to the dimensions of the mini-tractor. The longer this element, the larger the whole technique.
Other details
After welding the channels, holes are made along the contour, which will serve for fastening various attachments and other structural elements. You should also think about the steps, they cling to both sides of the frame. The main material used here is an 8 mm St-3 steel sheet, which will also be used for the steering column transverse bracket. For additional strength of the joints, the transverse segments are supplied with “kerchiefs” made of the same steel that was previously used for the steps (however, the width of the sheet here will be slightly less, 5 millimeters).
How it is further manufactured After that, bushings of the suspension linkage of the bridge are welded to the front cross beam. They will also be made of ST-3 sheet metal. Sheet thickness - 2 centimeters. After that, bridges (front and rear, respectively) are attached to the frame.
Homemade: mini-tractors and parts for them. Learn more about bridges and beam
The bridge is made from individual parts and assemblies taken from similar agricultural equipment. Some use bridges from the 24th "Volga"
or "Moskvich". But in our case, such parts will not be used, because they simply do not fit into the dimensions of the mini-tractor. The exception is We will talk about it in more detail a little later.
Details to be done by yourself
Details such as bushings for rotary, wheel and support axle shafts must be done by hand. The cross beam is also independently manufactured. To do this, take a piece of pipe with a square section measuring 65x65x5 millimeters.
If there is none, the beam can be made from Half-axle bushings are made from Slewing mechanisms are made from pieces of a metal pipe. To do this, a pipe with a cross section of 70x14 millimeters is taken and cut into several pieces 120 millimeters long each. They also need to make seats for bearings. After that, the resulting part is covered with metal welded covers. An assembled assembly is welded into the center of the beam (it must consist of 2 roller bearings and a cylindrical cage), with the help of which the rolling of this bridge will be allowed.
Bolts and nuts marked "M-30" should be used as fasteners of this assembly. They completely fasten the entire front beam. When tightening, place a special spring washer under the nut. It is worth noting that with each tightening of the bolted connection, you reduce the amount of play on the front axle relative to the mini-tractor. Thus, you will have the opportunity to adjust this node, if necessary, before each new implementation of agricultural work.
About the rear axle
Unlike the front one, it is not necessary to make it yourself. It is quite enough to install a standard "Volgovsky" element here. But, since the width of the mini-tractor does not correspond to the dimensions of the GAZ-24 bridge, we will have to shorten it to 80 centimeters. To do this, the “stocking” fixation is removed, the heads of the rivets are cut off, and the rest is pushed deeper. The bridge is disconnected from the gearbox housing using a sledgehammer with the first element fixed in a special mandrel.
Thanks to these actions, you will ensure docking with the reverse gear, so that the cardan break will be excluded. Also, you will no longer need to balance and install counterweights on mini-tractors for summer cottages, which will significantly speed up the time of work performed.
In order to fix the shortened "stockings" in the holes, a thread ("M-12") is cut and screws are screwed in there. The resulting bridge is attached to 8 plates. The latter are welded with bolts ("M-10", 4 for each plate) and nuts to the spars. The spring washer locks the connections. To do this, identical plates are welded onto the bridge. At the final stage, self-made brackets are installed under the mounting of the hinged frame. For the lifting mechanism, the body of the lift shaft is welded to the axle housing.
The final stage
Now the matter remains small: a seat is welded to the resulting structure, and all equipment is painted in one monotonous color (if desired, several aerosol cans of different shades can be used). Behind the equipment is installed for the possibility of working in a hitch with a plow.
How to make a mini tractor for the household with your own hands? Method number 2
This method is simpler than the previous one, however, here you will need to have your own walk-behind tractor to complete the work. At the same time, it is not necessary to purchase a new one; some old Soviet Ural or Neva is quite suitable for a tractor.
What do we take from a walk-behind tractor?
The "heart" will be removed from this unit, that is, the motor, which will be the main traction device of the tractor. All other parts can be used for spare parts. In addition, during the work you will need starting device, bridges and wheels to them.
Further assembly technology practically does not differ from the previous one; a welding machine, metal pipes and
Getting Started
So, how they are done First, the kinematic system of technology is designed. Traction forces coming from the internal combustion engine of the walk-behind tractor must be transmitted through the roller chain to the intermediate shaft. Also, with the help of the penultimate device, power will be transmitted to the drive wheels. A brake (band) is located on the output shaft, and a gearshift lever is installed along the axis. The engine will be started via the starter pedal. In principle, a mini-tractor for the household is not such a complicated technique as it seems at first glance, so you can make it based on just one drawing.
The frame will be made of steel pipes and corners. It is also necessary to provide a fork with a bushing for turning the trailer (if the tractor is coupled with it or a plow). The so-called "cheeks" are attached to the housing of the bearing assembly, and the output shaft is tightly welded to the "kerchiefs" of the socket. We do the front beam and the rear axle in the same way as the previous method.
Further, the home-made mini-tractor is supplied with a metal body with a side height of at least 30 cm. All this must be made of sheet steel. At a distance of 80-85 centimeters from the end of the spinal beam, a soft seat is installed from a thin sheet of plywood (optionally, it can be sheathed with leatherette filled with foam rubber).
At the final stage, we equip a mini-tractor for the household with our own hands towing device. After that, the equipment goes through the procedure of priming and painting.
So, we figured out how to make a mini tractor for the household with our own hands.
All household or small farms have to use a lot of manual labor. It helps to reduce its share assembled mini tractor with your own hands. It can be used for a variety of purposes, including hay harvesting, tillage, crop or fertilizer transportation. Performing such operations without mechanization at home is problematic.
Large agricultural companies solve the issue of buying foreign or domestic agricultural machinery. It is not always possible for small farms to allocate the required amount for a minitractor, so they have to come up with and implement home-made developments. For a do-it-yourself household, the entire assembly is carried out from improvised materials. If necessary, certain power units are made more powerful, and the product is conceived as maintainable as possible with a universal set of spare parts and consumables.
Pros and cons of a homemade mini tractor
The wide popularity of this type of technology is provided by the advantages:
- Comfortable operation in limited space conditions. For a homemade mini tractor, fields of less than 2-3 hectares are optimal. Larger areas are processed with larger and more powerful equipment.
- Not all areas are effective manual digging. This refers to rocky or hard ground texture. At the same time, manual labor will be much harder. It is more appropriate to use in such circumstances a mini tractor for the household, which in a matter of minutes, with the appropriate attachments, will complete the task.
- Making a mini tractor with your own hands will often turn out to be cheaper, especially when a power plant from other equipment is available. You can make the rest of the nodes with your own hands, the drawings in this case will be unique.
- Ample opportunities for reconstruction, restructuring, refinement and repair. Since you will have to make a minitractor yourself from improvised means, you can put the prospect of re-equipment into the schemes in advance.
- Homemade will have a small weight, which will not create an excessive load on the soil. This makes it safe to use even when caring for crops during cultivation, hilling or harvesting.
With all the positive factors, those who decide to make a mini tractor with their own hands need to be aware of the future disadvantages. Most spare parts will be unique, so sometimes it can be difficult to find analogues. This practice should be taken care of in advance.
Also, the owners of this equipment will be prohibited from driving on public roads. To fix this, you will have to go through a long journey of registering your vehicle. Otherwise, it will have to be transported to the arable land or to the garden not on its own, but on a trailer. You can get a fine for driving a homemade car on a regular highway.
VIDEO: How much does it cost to make a mini tractor with your own hands
In order to correctly implement the design plan, it is necessary to have real drawings and dimensions of future elements and assemblies.
Unit drawing with dimensions
It is important to prepare the following main modules:
- power plant of optimal power;
- transmission for transmitting power from the engine to the wheels;
- base in the form of a frame structure;
- steering;
- place for the driver.
If not the entire set is available, then it is worth looking for the missing parts at car showdowns or at vehicle recycling points. Also, something is easy to pick up at the service station.
We assemble the frame ourselves
The base is often welded from a channel or an I-beam. They are selected from the interval from No. 5 to No. 9. The system will be very solid. Most often, two semi-frames are used for a breaking frame, which are interconnected by movable hinged joints in the form of parts cardan shafts from the truck.
Frame for a future fracture from a channel
Also, the frame can be one-piece, assembled from two spars and crossbars. The crossbar is made of channel No. 10. When using the labor of assistants, it is preferable to have a drawing available in order to obtain the desired result.
Engine preparation
Before you assemble a mini tractor with your own hands, you should take care of the motor. An engine with a power of about 40 hp is considered sufficient. Power plants UD-2, M-67, UD-4, MT-9 fall under this criterion. Also, assemblies based on cylinder blocks from an old VAZ or AZLK are not uncommon.
Masters for housekeeping strive to create all-wheel drive models. We recommend assembling such machines with a 4x4 wheel arrangement based on the M67 engine. In this case, it is necessary to ensure an increase in the gear ratio in the transmission. If this is not done, then the motor will lack torque. It is important in this situation to form an additional cooling system.
It is very convenient to make a tractor from a walk-behind tractor. In this case, the power unit, front axle, brakes, gearbox, frame and steering system are already ready.
In the traditional layout, the motor is located in front, directly above the front axle longitudinally. Through the clutch, a gearbox is mounted to it. Further, according to the scheme, there is a razdatka and a drive axle. The connection of elements in such a scheme is carried out by means of couplings or several cardans.
Sometimes it is more convenient to place the motor on the frame, placing wooden boards under it. In this way, it will be possible to find the optimal position for him. If necessary, brackets are made for convenient fixation of the cylinder block.
It is important to observe the weight distribution in order not to get a quick tipping system. Experienced experts recommend spreading the mass along the axes in a ratio of 60% to the drive axle and 40% to the driven (steered) wheels.
Transmission and rear axle
The most durable and inexpensive gearbox is a box from Soviet GAZ-53 trucks. From them or from the GAZ-52, a clutch system is used. When mounting on a frame, it is worth taking care of additional adjustment of the nodes to each other. There are home models with components from UAZ. Their power parameters maintain a high level of reliability.
It will be possible to synchronize the clutch and the motor through the assembled new housing (basket). You will need to cut the rear plane of the flywheel power plant. You will also need to drill an additional center hole.
As rear axle mini tractor, a ready-made assembly is taken from a passenger car or truck. It is important to adjust the dimensions of the axle shaft in such a situation. For a 4x2 wheel scheme, where one of the axles is not leading, it will be easier to select the front axle shafts.
Steering wheel and wheels
Since it is supposed to make a home-made mini tractor for power loads, it is important to choose steering with a hydraulic cylinder in the scheme. At home, it will not be possible to make such a hydraulic device, so it can be picked up at a dismantling of cars or agricultural machinery. We will also borrow the steering trapezoid.
As a seat, you can use any suitable object - a seat from a car, an armchair, even a stool will come in handy if it is properly fixed
Wheels for homemade must be chosen with a radius of more than 13 inches. They are suitable for equipment designed for transporting goods. If agricultural work is expected, then a radius of 18-24 inches should be preferred.
The support pins are forks from Soviet cargo universal joints. We cook a couple of forks to the beam or directly to the frame, while maintaining alignment. The rest are welded to the steering knuckles.
VIDEO: Interesting ideas for assembling a homemade tractor and attachments
A mini tractor for a small farm is, if not necessary, then a very useful technique. The unit mechanizes plowing, harrowing, cultivating the land, removes and takes the crop from the field, and helps in forage harvesting. The capabilities of the device are expanded by additional equipment.
There are enough proposals for mini-equipment on the agricultural machinery market, but the prices of the simplest and least functional Chinese-made machine start at 120 thousand rubles. A home craftsman can significantly reduce costs by making a mini-unit, equipment for it with his own hands.
Choosing the parameters of the future car
Consider on what factors and parameters the stability of the minitractor depends.
Power point
The master needs to clearly decide what you want to do with a home-made unit and in what area. The power of the power plant will largely depend on this. The experience accumulated by specialists allows us to recommend:
- engine installation 4-7 hp with the area of the cultivated area up to 20 acres;
- 9-17 HP up to 50 acres;
- 20-40 HP up to 4 ha.
For the operation of additional equipment, the engine must be equipped with a power take-off shaft.
Chassis, steering and transmission
Most homemade units have frame structure on two axles with pneumatic wheels. The drive can be on one or both axles. It is advisable to use a mechanical type transmission with a gearbox, clutch assembly, cardan shafts and bridges from light car or agricultural machinery.
In the same way, steering nodes are selected, brake system, electrical appliances.
Having sufficient capacity of the hydraulic pump, hydraulic motors, distribution devices and power hydraulic cylinders, it is realistic to equip the unit with a full volumetric hydraulic drive, which will make it possible to abandon mechanical gears, will simplify the steering scheme.
Such a solution will greatly facilitate the creation of a machine with a breaking frame - two half-frames are connected by a power hinge assembly, which increases the maneuverability and maneuverability of the minitractor, and ensures that the axle wheels copy the uneven ground.
The use of a caterpillar-type mover significantly complicates the design, it will require the presence of light links of the caterpillar belt, the development of power moment transmission units for each of the belts with different parameters (for turning and turning), and the installation of track belt tensioning mechanisms.

Making a clutch for a mini tractor
The clutch basket casing is connected to the motor through an adapter with coaxial mounting holes. The device itself was used from GAZ-51, the mechanism is turned off by a hydraulic drive.
Mini tractor features:
- components and parts are used from used cars and agricultural machinery;
- a breaking-type frame is assembled from two half-frames and a crosspiece from a MAZ truck. Provides high cross-country ability and maneuverability of the machine, copying the terrain with pneumatic wheels, directional control;
- a cardan shaft with a pair of end crosses, transmits the power moment from the box to the bridge, regardless of the "kink" of the frame;
- a drum-type service brake is mounted on the box shaft;
- the drive axle is used from an electric car, rigidly fixed to the semi-frame;
- front axle suspension independent. Shock absorbers, springs, levers are used from ZAZ;
- the machine can be converted into tracked and all-wheel drive versions.
The Volchok unit is converted into an all-wheel drive mini tractor with its own hands in the following order:
- Behind the gearbox through the intermediate cardan shaft a transfer box from the GAZ-69 is installed, which transmits the power moment to the drive axles, the presence of a reduction gear in the device allows, if necessary, to increase the traction force.
- A bridge is mounted on the front half-frame - an analogue of the rear axle of a minitractor.
- main gear front axle connects with transfer case through a driveline.
Alteration of the "Volchka" into a caterpillar minitractor with your own hands:
- Build a caterpillar type propeller. For this purpose, a large diameter tire with cut sides is used. We use solid rubber wheels from transport carts as rollers.
- We fix the semi-frames rigidly relative to each other (the power hinge does not work).
- We dismantle the front suspension, on the front half-frame we fasten the roller units with the track tension mechanism.
- We dismantle the rear axle, in its place we install a shortened axle from the GAZ-21 with the main gear and differential, hydraulic control drum brakes are connected separately for each side. into place rims install rollers.
- Two drum brake pedals on the rear axle, through the operation of the differential, provide a change in direction.
- We dress and pull the caterpillar tape.
Optional equipment
Having made a trailer with your own hands, you will significantly expand the functionality of a mini tractor, minimizing financial costs.
We start manufacturing with a supporting frame - welding of round or rectangular pipes (at least 40 mm in cross section) of the product frame. The axle of the wheelset is made of a steel rod with a diameter of 35 mm. The axle is connected to carrier frame longitudinal hinge, side spars and corner supports.
The body box is made of edged planed boards connected with screws and metal corners.
To attach the product to the minitractor, an articulated drawbar inserted into the tubular body is used. Coupling with vehicle secured by a chain type fuse.
