It has four-wheel drive and a fracture-type frame. the author produced works in his spare time, using the materials of the forums and his own skills. The all-terrain vehicle was going based on the reliability of structures, but not forgetting about the comfort of the driver and passengers. The main purpose of use is to travel along forest routes for hunting, fishing or gathering supplies, so the all-terrain vehicle has a large capacity and carrying capacity.
Materials and parts required to create this all-terrain vehicle:
1) Engine internal combustion from the car oka
2) Variator Safari
3) a gearbox from an oka car.
4) pump dispenser
5) Oi-25 tires are lightweight.
6) shaped pipe
Let's consider in more detail the stages of building an all-terrain vehicle, as well as its main structural units.
The frame of the all-terrain vehicle was reinforced with shaped tube structures.
The rear of the all-terrain vehicle was created:
rims were made and tires were put on oi-256
Then the author started making all-terrain vehicle bridges:
Other works on the transmission of the all-terrain vehicle:
The body of the machine for the all-terrain vehicle cab was taken:
Unloading wheels and main parts for assembly:
This is how the steering is done:
All-terrain vehicle cab installation works:
And connections to the trailer:
The all-terrain vehicle is capable of speeds of about 35 kilometers per hour and this is not the limit, there is enough power, but control at such a speed becomes very inconvenient. But as you know for an all-terrain vehicle maximum speed not so important, since the main routes it will pass in first and second gears at speeds up to 15 kilometers per hour.
The length of the car turned out to be about four meters and twenty centimeters. The height of the all-terrain vehicle is two and a half meters. The total weight of the car is about 700-800 kilograms, but it will still grow, since the author has provided for several mandatory upgrades for this all-terrain vehicle.
The speed of about 35 km / h was measured by GPS, then it's scary.
A differential was welded onto the gearbox before installation on the all-terrain vehicle, since a differential is not required in this transmission design scheme.
A few more photos of work on the structural elements of the all-terrain vehicle:
As you can see from the photos on the all-terrain vehicle, the front axle is not slightly overloaded, in particular, due to the massive cabin and the absence of a box as such, in the future, instead of a trailer, the author plans to make a box, or rather, finish it right on it using a frame made of a profile pipe and sheets of metal or plywood ...
It is also planned to complete the boats so that the all-terrain vehicle can cross water obstacles.
Initially, the author planned to install Krazov wheels, since they are better suited for an all-terrain vehicle of such a mass. nevertheless, the OI-25 is too small for such a weight, in addition, a large width of the wheels is required, since the center of gravity of the all-terrain vehicle is quite high and there is a possibility of overturning. That is why the author intends in the future to install all the same KrAZ tires and make a safety arc. when will work on the frame of the kunga begin.
But with the replacement of tires, the disks will have to be changed, since they were made specifically for the OI-25 and have a width of 450 mm.
In rural conditions, the tractor is the main assistant. For small farms, compact models that are economical in consumption and versatility will be relevant. Small motorized agricultural machinery is offered to users by popular manufacturers, but skilled craftsmen are able to independently assemble the device that is optimal for their needs, for example, a fracture mini-tractor.
Technique capabilities
In the agricultural area, these machines are capable of doing a huge amount of work. Due to its maneuverability and the possibility of attaching an additional attachments assembled mini tractor breaking the classic 4x4 with his own hands copes with the following operations:
- deep plowing of the soil;
- cultivation to remove weeds;
- harrowing of certain areas;
- implementation of sowing spring field operations of cereal crops;
- planting / harvesting potatoes.
In winter, a breakage mini tractor may also not stand in the garage, but clean the roads from snow. A trailer is attached to the towbar, which helps in transporting loads up to several hundred kg. Owners can even use mini tractors at home for mowing lawns.

Technical characteristics of the minitractor fractures
The assembled mini-tractor with your own hands has a number of positive characteristics, including a certain cost savings for the purchase. The pluses of homemade products include:
- the compact dimensions of the transport ensure its convenient operation even in small areas, and since most farms include small sown areas, a self-assembled fracture mini-tractor will be very appropriate;
- home-made devices with a single-axis drive or with a full drive, in the overwhelming majority of cases, pay off in one or two seasons, and subsequently allow you to save on components;
- agricultural novelties have decent performance indicators that can compete in work with factory models, since the master can independently make a mini tractor using selected units and components that have a large margin of safety.
It is worth considering that a homemade 4x4 fracture mini-tractor may have disadvantages. The disadvantages lie in the following factors:
- sometimes the process of finding the necessary units or individual parts is delayed;
- in the case of using non-standard structural elements, it is difficult to carry out repairs;
- it will be possible to assemble a homemade 4x4 mini-tractor if you have an appropriate set of tools and possess the skills to work with them;
- frequent breakdowns may arise from the use of old used technical units.
Assembling the frame
The frame structure is optimal for DIY assembled in the garage. The key parts for it are the longitudinal spars and a pair of transverse beams. It is preferable to make spar beams in a three-stage form from the tenth channel, and for the traverses, a sixteenth square profile in the front and a twelfth in the back is suitable.
Breaking frame machine dimensions
It is important during the assembly process to ensure that the front half-frame can be rotated relative to the rear half-frame at a certain angle. Truck hinges are suitable for this. In most cases, cropped ones are used. cardan shafts... When folded at an angle, they continue to transmit rotation.
After assembling the frame, proceed to the installation of the power unit. It is recommended for machines with a drive on one axle to take engines from the interval of 15-30 hp, and for an all-wheel drive fracture, an engine with a power of 30-40 hp would be the best solution. Preference should be given diesel units water cooled. They are quieter in operation than counterparts with air removal of excess heat.
Kinematic diagram
As a ready-made solution, installation on the frame of engines from motoblocks or old cars is allowed. There are drawings where the central place is occupied by power plants from such models:
- walk-behind tractor "Neva";
- model with the Zubr walk-behind tractor;
- homemade from the "Centaur" walk-behind tractor, etc.
As a minimum exhaust system an empty metal fire extinguisher may participate, inside which metal shavings from a lathe have been stuffed. If a motor with air cooled, then in the lower docking area, part of the partitions can be removed. It is also important to ensure that there are mounting holes to secure the power unit.
The next step after the installation of the engine is the installation transfer case and gear boxes. An acceptable option is to choose them from the GAZ-53. For a high-quality docking of the clutch with the engine, you will have to redo the flywheel. In such a situation, turning work will be needed.
The back is cut off, the surplus with the tides. A hole is bored in the center for a new shaft. The clutch basket cover is optimized in size to the desired dimensions.
Assembly of axles and wheels
Global bridge redesign is not done at home. It can only be adjusted according to the lengths of the axle shafts so that the wheels are located in one axle and do not protrude significantly beyond the dimensions set according to the drawings.
The bridge is fixed with 4 sturdy ladders. A thread for nuts is cut on them in advance, and then the rods are heated with an autogen or propane to a U-shaped state. You need to weld them with a fixed bridge, relative to the entire power transmission chain.
Most craftsmen make the front axle of a mini tractor on their own, since in rear-wheel drive models it is used only to control transport. It can be strengthened with high-quality disks from ZIL-130.
Wheelsets should be given special attention. It is hardly worth using tires from a passenger car in a serious design. Often this step is taken at the initial stage. The preferred tire size should be over 14 inches. Otherwise, the passability of the novelty on loose soil will objectively decrease.
The correct wheels are grouser models. This solution will provide high permeability in any area without sinking into the soil. You can simulate lugs by wrapping chains around the wheels. This method will achieve many advantages:
- operation will be simplified;
- cross-country ability and maneuverability will increase.
It is customary to put control with a hydraulic booster on the break. Such a node can be found on decommissioned equipment. An oil pump will be installed in the structure, used to maintain the required pressure value. A mandatory gearbox is used for the main rotation shaft. It is involved in steering the wheels.
Steering diagram
Opposite the steering wheel, the driver's seat is mounted, from which control takes place. It is taken from old cars. Installation must be done in such a way that the knees do not rest on the control system.
From old Zhiguli, a drum hydraulic brake is mounted on the front wheels. Several metal rods are used to connect it to the pedals.
Do not forget about the summer canopy that can replace the cab. It is customary to mount it on 2 or 4 posts welded to the frame. An alternative to it is a protective metal arc. Light optics are mounted for work at night. It is attached to the generator and battery.

Many farmers are interested in how to make a fracture mini tractor with their own hands. The mini-tractor helps to efficiently and quickly plow even the most extensive areas. You can make a homemade tractor with a break frame yourself in order not to spend money on the purchase of an industrial unit.
What is a fracture mini-tractor
Outwardly, such a homemade 4x4 fracture mini-tractor is a conventional mechanism. The operation of such a machine is provided by the walk-behind tractor that underlies it.
Conventionally, a mini tractor with a break frame can be divided into 3 categories:
- Homemade - a 4x4 tractor, assembled by hand.
- The factory model is a classic for those who do not risk making a break with their own hands.
- 50/50 - a factory tractor, modified by the tractor driver to the desired result on his own.
Let's present an overview of a hand-made fracture mini-tractor. Consider yourself from the simplest elements.
How to make a fracture mini-tractor with your own hands
Homemade minitractors with a breakable frame require certain skills from their manufacturer. Building such a machine is not easy. There are quite a few options for making a homemade minitractor, but among homemade products there are the best option, which can be done, based on the necessary drawings, almost everyone, even novice designers. You can find the necessary calculations and a diagram of the assembly units on the Internet.
You need to start assembling a homemade 4x4 fracture tractor by carefully studying how to design a frame. The frame consists of 2 main components:
- The spars are a three-stage prefabricated element. The front steps are assembled from channels (tenth sizes), the outer steps are constructed from a steel square pipe, the width and length of the sides of which are 80 mm.
- The traverse on the rear of the tractor is made from 16 channel bars, the front traverse is made from 12 channel bars. The cross member is made in the same way.
Tractor power plant
As for the engine for a homemade tractor, breakage 4x4, any can be used here power point corresponding to the power requirements. As a rule, experts recommend using a four-cylinder diesel engine equipped with a water cooling system. Power 40 hp it is quite suitable for a tractor on which it is planned to work on small-sized personal plots. A tractor with an Oka engine is often used, sometimes with a VAZ engine. In rare cases, it is allowed to start a tractor with a Lifan engine. It is best to make a unit with an Oka engine.

The gearbox can be used from a non-working GAZ vehicle. In order to connect the clutch basket to the motor, it is necessary to design a flywheel with an engine from scratch and make a modernized basket cover so that it can be adjusted to the required dimensions.
The bridge does not require special knowledge or skills, since it is installed on the equipment without any changes. It is attached to the frame with 2 pairs of ladders.
The propeller shaft can be taken from any car, and in order to provide the car with high-quality shock absorption, you need to install tires with a diameter of 18 inches.
The wheels are installed on the hubs simply. The central part is cut out of the disk, where the hole for installation is located. Instead of this part, the designer welds the center of the disk from the ZIL-130. The front axle can be made independently, as this does not require special skills: this bridge will not be the leading one. If you are afraid to take on such a responsible business, just take the bridge from another car.
Manufacturing of tractor wheels
Consider creating a mini-tractor wheelbase. You can install wheels removed from passenger car, however, here it will be necessary to take into account a number of factors at once. So, wheels mounted on front axle should be approximately 14 inches in diameter. In the event that you choose smaller wheels, there will be a great risk of malfunctioning of the structure in the future: the tractor runs the risk of falling into the ground. However, you cannot overdo it with dimensions, otherwise the tractor driver will have to make great efforts to perform even the simplest maneuvers: the steering wheel will be very difficult to turn. However, this task can be simplified a little if steering column will be equipped with a hydraulic booster.
Please note that the tires on the tractor must be equipped with good lugs. This will make the mini tractor, created with your own hands, more maneuverable, reduce the load on the wheelbase and simplify work on it.
See " Instructions for self-repair of the main working units of the T-40 tractor
For greater maneuverability, a do-it-yourself mini-tractor of a break can be equipped with a hydraulic power steering column. The hydraulics can be removed from any other agricultural equipment. To assemble such equipment, you will need an oil pump that will be powered by an engine. This element creates correct pressure in the hydraulic motor.
If you want to achieve maximum ease of use, you can make an all-wheel drive fracture mini-tractor yourself. Four-wheel drive, even made with my own hands, allows you to achieve good maneuverability. Of course, all-wheel drive makes the assembly of all structural components more difficult, since you will have to make the shaft with all the quality and correct connections.
If you are going to make a tractor with four-wheel drive, it is recommended to find a video review, where it will be shown in detail and told about how and what to do. Remember that assembling a mini tractor will require utmost care.
A mini-tractor 4x4 fracture with their own hands is designed with the help of a variety of spare parts, most of which are borrowed from cars, but not only they will be needed during work. For example, in order to make a pivot point or a break point, you need to acquire a welding machine, drill, fasteners and tools for joining parts. The fracture node for a mini tractor requires special attention during collection and you may need to turn to professionals for at least advice.
A fracture tractor with its own hands cannot do without installing a driver's seat. As a rule, the control system, including the seat, is installed after the main part of the work with the frame with your own hands is over. This technique often uses chairs taken from passenger cars... Such an item is easy to purchase at any automotive store. Remember that the steering wheel must be at a comfortable height for the tractor driver. It should not be placed too low above the knees, but also should not be installed high: hands can quickly get tired.
