Homemade mini-tractors: types and features
This class of agricultural machinery usually includes three types. each of which has its own characteristics:
- Multifunctional equipment with which you can perform tasks such as tillage, grass mowing, garbage collection, etc. Most often, such homemade mini-tractors are equipped with a power unit with average power, which is enough to cultivate an area of up to 5-6 hectares. If necessary, mounted devices can be installed on such equipment, thanks to which you can expand the list of tasks that can be solved with the help of such mini-tractors.
- Riders. The main purpose of such equipment is the application of fertilizers and treatment with pesticides. In addition to this, they can be used to solve other problems using special equipment; these machines are designed for small plots of land.
Homemade mini-tractors, whose specialization is mowing grass and cleaning up garbage on the site. This technique can process an area of 1-2 hectares, and it is also often used to create lawns.
Design features and scope
This model of a home mini tractor differs from prototypes identical in power by its optimal system layout and modern design.
- The flexible traction and coupling characteristics of the Xingtai 244 model determine the possibility of using the machine for mechanization of labor-intensive work in the agricultural, municipal and construction sectors.
- Wide functionality also allows you to mount the tractor with productive loading and excavating equipment, a bulldozer blade, and use a power take-off mechanism to drive stationary devices.
- The tractor provides high quality agricultural work on an area of up to 5-6 hectares. A small-sized and highly maneuverable machine with mounted units for utility purposes works effectively in hard-to-reach areas of urban infrastructure.

Homemade mini-tractor: pros and cons
First of all, such machines are in demand among owners of private farms. There they are used to perform tasks such as gardening, removal and destruction of waste from tree cutting, as well as landscaping.
This technique has certain advantages. which made her popular:
- High-quality deep tillage. For some areas, digging up the soil by hand is not always suitable. If the soil has a hard and rocky structure, then this work can be physically very difficult. In such cases, it is more than appropriate to use homemade mini-tractors, which will cope with such a task in a matter of minutes;
- Ease of use in a small area. It makes sense to use large tractors for cultivating large agricultural lands with an area of at least 10 hectares. If you need to dig up smaller areas, then a mini-tractor is better suited for this work;
- Low price. The cost of a homemade mini-tractor is formed mainly from the costs associated with the acquisition of components;
- Possibility of converting a homemade mini-tractor. If necessary, additional equipment can be installed on the mini-tractor, which will make it more functional. At the same time, due to its light weight, such equipment does not greatly disturb the soil structure and does not require large repair costs.
This technique also has disadvantages. This should include the fact that the owner will have to independently look for components for the machine. If some rare part was used during the assembly process, it will be quite difficult for him to find the same one to replace it. However, the most common practice is when components are most often used to assemble mini-tractors with your own hands, which can be easily found in case of failure.
If you decide to assemble a homemade mini-tractor yourself in order to drive it on public roads, keep in mind that you must have permission to do this. Otherwise, you risk getting a fine for converting your car.
How to make a homemade mini tractor with your own hands
The main question that arises for those who are interested in a mini tractor is how to make this machine? There are many ways to assemble a homemade mini-tractor at home. The process of assembling this equipment is as follows:
- The first stage begins with the manufacture of a frame, for which a rolled channel is used. The design must contain cross members located at the front and rear, and several spars. When creating a frame for a mini-tractor, it is necessary to slightly reduce the width of the front part, thereby giving the part a trapezoidal shape. Care must be taken to create a hole in the frame so that other elements and devices can be attached to it.
- Then the racks are taken and welded to the corners. They will play the role of a subframe in the design. Additionally, they need to be connected at the top. The rear axle is installed on the finished frame. If the project involves the assembly of an all-wheel drive mini-tractor, then the front axle is placed on the frame.
- Next comes the turn of the engine, which must have the necessary power. The most affordable option is a motorcycle engine.
- You also need to find a place on the frame to install the gearbox. Moreover, the latter must be placed in such a way that it is directed towards the driver, thereby making it easier to control the process of driving the tractor.
- The next stage is the installation of steering elements. For homemade mini-tractors, a steering wheel borrowed from domestic passenger cars is most often used. Sometimes you can use a motorcycle handlebar.
- Next you need to install a trailer hitch, which is welded to the frame.
- The brake system and tank are installed, after which they proceed to connecting the electrics.
If you go online, you can find many different drawings for assembling a homemade mini-tractor. Therefore, having selected a suitable scheme, you can immediately start working, focusing on one or another option, or make changes to a ready-made one, taking into account your needs and tasks.
Areas of use
Homemade mini tractors have similar technical features as full-fledged Belarusian units. Chinese and Russian production, presented in stores. That is why their scope of application will be virtually the same.
Naturally, the main work for a homemade unit will be plowing, cultivating, and other cultivation of land. This task is paramount, because the farmer is fed by his harvest, i.e. something that he planted with his own hands, and without proper soil preparation this is almost impossible.
This largely explains the necessity and indispensability of such equipment for agriculture in general, as well as for specific farmers in particular.
In addition, with the help of a homemade mini tractor you can carry out a whole list of typical work:
- clearing snow in winter;
- transportation of small loads;
- cleaning of household waste, as well as various vegetation;
- hay making;
- planting and digging potatoes, beets, etc.
It is understood that the ability to perform such work is realized only in combination with certain equipment that plays the role of auxiliary. We are talking about trailers, rotary and segment mowers, snow plows, etc.
It is through the aggregation of these devices with a homemade mini tractor that it becomes possible to expand working capabilities, as well as increase multitasking, which everyone is talking about.

Instructions
Do-it-yourself homemade mini tractors at home are a fairly standard design, although not attractive in appearance.
But the issue of external beauty plays absolutely no role here, because self-assembly only requires the presence of those performance characteristics and indicators that allow a fairly extensive range of work to be carried out.
At the initial stage. you need to do one very important thing - draw up a detailed drawing of the future unit, indicating the exact dimensions and main working units. If you do not have the necessary knowledge in this matter, you can use outside help.
And in general, you can use the Internet by entering the request “do-it-yourself mini tractor, drawings, dimensions” into the address bar, and you will immediately see more than one detailed assembly diagram.
Frame. is a supporting structure. All attachments are attached to it.
This step is very important, because independent production of any unit involves certain modifications and adjustment to the required parameters. Obviously, the easiest way to do this is by drawing. than to navigate approximately.
To run a successful and productive household, you need appropriate agricultural equipment. By clicking on the link, you will learn how to make a cultivator yourself.
The plows have improved characteristics, which allows you to easily cope with plowing any land as quickly and efficiently as possible. Here is everything about the different types and characteristics of the PSK plow.
Currently, technological progress is helping to replace long human labor with much more efficient machine work. The Polesie combine harvester is your indispensable assistant with excellent quality for decades.
In addition, the same turner will understand what is required of him by looking at a detailed drawing rather than a formal explanation in words.
It becomes clear at the project planning stage. what kind of unit will be in the end. The DIY mini tractor, located on an articulated frame, is quite popular among many.
However, this is far from the only assembly method, so the choice lies solely with the person who will carry out the manufacturing.
Having decided on the type of mini tractor, the question arises of finding the necessary spare parts and components. We are talking about the frame structure, engine, transmission, controls and wheelbase. Most of this can be found on the Internet by visiting sites that specialize in selling various spare parts.
The assembly process itself will include several stages:
- Making the frame. The fracture is carried out mainly from channel number 5 and channel number 9. Two half-frames need to be welded from these components, and they will be connected to each other using a hinge. In this capacity, driveshafts from heavy-duty vehicles can be used.
Frame making
- There is another way to construct the frame. It consists in the manufacture of a one-piece structure consisting of two traverses and two spars. The crossbars are made from channels number 16 (for the rear) and number 12 (for the front).
- The spars will be made from channel number 10. A metal beam is used as a cross member.
- As an engine, you can use models MT-9, UD-2, UD-4, etc. Their power will be quite enough for a homemade version. In principle, any engine with relatively high power - approximately 40 hp - will do.
- The PTO and gearbox can be removed from the GAZ-53. and take the clutch from a GAZ-52. Remember that these parts will have to be adjusted to the design parameters. You need to cut off the back part of the motor flywheel a little and also drill a hole in the center.
- The steering wheel can be provided with a hydraulic system, which must be taken from old agricultural machinery.
- The design of the rear axle can be borrowed from old passenger cars. but you will have to adjust it a little on a lathe.
- Any suitable wheels can be used, but their diameter should be about 18 inches - this is the acceptable minimum for agricultural work.
- In this sequence, in principle, lies the answer to the question - how to make a mini tractor at home? Most of the necessary components can be obtained from old equipment. which greatly simplifies the issue of finding the right part.
In addition, the costs are minimal, because even purchased parts will cost much less than a finished mini tractor.

Advantages and disadvantages
Perhaps the main advantage of a homemade mini tractor is the absolute savings in money. compared to purchasing full-fledged units in a store, such as Uralets. Kubota. Bulat 120. Yanmar. Belarus 132n. Scout.
At the same time, its performance indicators will not differ much from the factory versions, because the design uses a fairly powerful motor, which is quite enough to cultivate land holdings of up to ten hectares.
Manufacturing costs for a mini tractor pay off in almost one calendar year, because most of the components are taken from old equipment, or the cost of purchasing them is minimal. Many people adapt other equipment, such as a walk-behind tractor, to a minitractor. which further simplifies the assembly process.
In addition, homemade units have other advantages:
- Relatively high degree of immersion into the soil. If everything is planned correctly, the digging depth will be identical to that shown by purchased analogues. Be that as it may, it is still better than digging up the garden by hand.
- Quite high mobility. due to its rather modest dimensions. The use of such units is advisable specifically in small gardens and summer cottages, where large tractors cannot turn around.
- Due to the fact that you make the mini tractor yourself, there is the possibility of additional modernization of the unit. You can remove components, replacing them with other, more powerful ones, or add new devices.
- In mini tractors sold there is no such possibility; moreover, the operating instructions explicitly state that making any changes to the configuration is strictly prohibited.
disadvantages include the following:
- Relatively complex assembly process. Here we are talking not only about direct work, but also about certain difficulties in selecting the necessary components. Many of them have to be adjusted on a lathe, which in itself represents an additional complexity.
- Possibility of breakdowns. after all, the homemade version is made mainly from old parts and spare parts.
In principle, the pros and cons are approximately equal in degree of importance, but there is one small digression. Today's realities are such that the issue of price becomes paramount. overshadowing other arguments.
A detailed explanation of this phenomenon is unnecessary, because economy has always been decisive, regardless of where it is applied.
Additional Tips and Warnings
Before you begin full operation of a homemade mini tractor, you need to register it with the traffic police.
This is not a mere formality, but an understandable necessity, because when driving on public roads, you may be subject to fines, and the unit itself may be transported to a impound lot.
Engine of a homemade mini tractor
As for the technical aspects, this too has its own specifics. So that the engine of a homemade unit produces the necessary parameters, i.e. about 2 thousand revolutions at 3 km/h, you need to slightly adjust the transmission diagram. In general, ideally, each wheel of the rear axle should be equipped with a gearbox.
If the basis for the mini tractor is a walk-behind tractor. for example Cayman. Patriot. Texas. Foreman Viking. Forza or some other, it is better that it has a special coupling that allows you to attach additional equipment to it. In general, you should carefully select the model of walk-behind tractor that you want to convert into a mini tractor.
The Centaur walk-behind tractor may be perfect for these purposes. with a power of 9 hp and also having the necessary technical data necessary for the alteration.
Converting a walk-behind tractor into a mini tractor: main points
Unlike amateur equipment, professional and semi-professional equipment has a greater service life and power. For example, from a walk-behind tractor with a 9 hp diesel engine. you can make a pretty decent mini-tractor for plowing and cultivating. Ultimately, it all depends on the goals that the owner of the modified equipment intends to achieve.
Designing and assembling a homemade mini tractor is not an easy task, but it is doable. And to solve it successfully, you need to focus on two points:
- Development of a body and frame, as well as a diagram of their connection with the base of a mini-tractor - a walk-behind tractor.
- Development of a kinematic scheme.
The frame and body of a homemade mini-tractor are made of metal corners or profiled pipes. When calculating the structure, it is necessary to take into account the ratio of its weight to the power of the motor, as well as the resistance that the machine will overcome when performing various types of work.
If you choose a powerful walk-behind tractor as the basis for a homemade mini tractor, this allows you to use ready-made car or motorcycle trailers. Moreover, leading manufacturers of walk-behind tractors have long provided for the design possibility of connecting such trailers to their manufactured equipment.
The kinematic diagram of a homemade mini-tractor is a set of design solutions that ensure the transmission of torque from the walk-behind tractor engine to the drive (mainly rear) wheels. When calculating, it is necessary to distribute the load on the drive axle evenly - both reliability and durability, as well as functionality, that is, the possibility of using the equipment, directly depend on this.
Popularity in Russia
Chinese Xingtai mini tractors are produced at the Tunde Selmash JSC tractor factory. The plant produces small-sized special equipment with a power of up to 30 hp. With. The factory has devoted more than forty years to this business. All products have a certificate of compliance with quality criteria. Certification from the National Supervision Authority is the main proof of the long service life of the product.
Xingtai mini tractors have been known among domestic consumers since 1992. The special equipment differs from its competitors in that it is fully adapted to Russian operating conditions.

DIY mini tractor: where to start?
In fact, there are many options for constructing a mini tractor yourself. However, the principles used are approximately the same everywhere:
- The gearbox rotates towards the operator and is fixed on the frame.
- Control is realized using steering rods.
- A hydraulic drum brake is used.
- The brake and clutch are pedal controlled.
- Manual control is used for the accelerator and attachments.
- The operator's seat is located above the rear drive axle.
One of the easiest ways to create a mini tractor with your own hands is to buy an adapter - a two-wheeled cart with a seat for the operator and an aggregate system (for installing attachments).
Obviously, to assemble a mini tractor you will need various spare parts. They can be easily found among automobile ones. For example, the drum brake for the drive wheels, steering rack and pedal control units can be taken from a VAZ passenger car. In the same way - by searching the auto parts market - manual control is selected. and a seat and other structural parts for a homemade mini-tractor.
But in addition to spare parts, you need to have a whole arsenal of tools on hand - a welding machine, drill, circular saw, wrenches, etc. And it is very desirable that during the process of assembling a mini tractor you have access to a specially equipped workshop or, if necessary, you can use the services of specialists in welding, milling, plumbing and auto repair.
Review of the Xingtai 120 mini tractor
The first models of this mini tractor rolled off the assembly line more than 40 years ago. Their production continues to this day. The main reason for this is the low price and high technical characteristics. Xingtai mini tractors have long been a global brand and have found application in many countries. This is achieved thanks to the excellent work of the marketing department of this company. They cooperate with a wide dealer network.
Xingtai 120
The Chinese mini tractor Xingtai 120 is distinguished by its small size and minimal maintenance costs. At the same time, it can operate a large number of different attachments, which allows you to expand the range of operation.
The first models of the Xingtai 120 mini tractor appeared on the Russian market in the early 2000s. Now they are still in demand among farmers and utility companies.

When using the Chinese Xingtai minitractor together with attachments (milling cutters, plows, etc.), owners should make sure that the aggregation is complete and correct, since otherwise the risk of damage to the Xingtai minitractor increases.
Mini tractor frame
The chassis is the basis of a mini tractor. Its main quality should be reliability, but you need to carefully monitor the total weight of the structure in order to ensure normal adhesion of the wheelbase to the soil when performing work and at the same time not to overload the engine.
To make the frame of a homemade mini tractor of medium power, a lightweight channel, profiled pipe or metal corner is suitable. The dimensions of the structure, the assembly of which is carried out by welding, must correspond to the dimensions of the machine. It is necessary to make holes along the contour of the frame for hanging and securing the structural elements of the mini tractor.
The ratio of the weight of the frame and its strength must be optimal. You should not overload the structure with additional stiffening ribs, nor should you skimp on metal, sacrificing overall reliability indicators.
Before you begin assembling the frame, you need to decide what trailers and attachments you are going to use when working with it. And in order not to lose your thoughts during the design process, before starting work you should make drawings of the future machine and its main components with the main dimensions. To do this, you can use ready-made documentation, which needs to be adapted to the specific parameters of your mini tractor.
Specifications
The tractor attracts attention with its classic design, combination of power and layout, maneuverability and increased cross-country ability. The overall dimensions of the vehicle with a wheelbase of 1.3 meters and a weight of 750 kg are within the range of 2.17 x 1.2 x 1.24 m
These indicators are organically combined with track widths of 960 and 990 mm, respectively. Cross-country ability is ensured by a high ground clearance of 275 mm, and maneuverability is ensured by a minimum turning radius of 3.5 meters for its class. Xingtai-120 works effectively on small plots of land and in closed volumes of farms, hangars and greenhouse complexes.
The power unit of the Xingtai model 120 is a proprietary liquid-cooled diesel engine DLH 190-12, with a volume of 0.7 liters and a power of 12 hp. A characteristic feature of the engine is its compact design, economical fuel consumption within the range of 189-195 g/hp/h, and the pulling force on the tow hook is more than 3 kN.
A fuel tank with a capacity of 14.5 liters increases the autonomy of the tractor at a considerable distance from refueling points. The engine is started by an electric starter; installation of a lever-inertial device for manual starting is optional.
