Considered the most maneuverable and easy to operate homemade tractor fracture, consisting of two half-frames. Assembling such equipment is more difficult than with a solid frame. This will require complex drawings and additional spare parts.
What is a fracture tractor?
In terms of design and dimensions, the fracture is nothing more than an ordinary mini tractor. Typically, such equipment is produced on the basis of a walk-behind tractor. There is a home-made tractor with a factory-made fracture frame or one assembled at home from old spare parts. There is a third option for fracture. The unit is assembled from a walk-behind tractor, and spare parts are used from a special conversion kit sold.
In terms of performance and a number of characteristics, a homemade tractor is inferior to a factory-made tractor. But homemade products also have their advantages:
- Properly assembled equipment can surpass powerful factory mini-tractors in functionality, and the cost of a home-made unit is many times less.
- The functionality of the breaking tractor can be significantly expanded to suit your requirements. Craftsmen adapt to technology those mechanisms that help perform the necessary work.
- The costs incurred during self-assembly of the tractor will pay off in 1 year.And if there are a lot of spare parts from old equipment at home, then the unit will cost the owner almost free.
The disadvantage of a homemade tractor can be considered the lack of necessary spare parts. If you have to buy them all, there will be no savings. Then it is better to immediately purchase a factory-made mini-tractor.
Fracture assembly technology
Before you start making a fracture 4x4, you need to draw accurate drawings of all components and frame. It's difficult to do this on your own. It is better to contact a specialist or search on the Internet. Although, the second option is not very successful, since there is no guarantee that the diagram was drawn correctly.
So, a 4x4 breaker is a mini-tractor with a four-wheel drive, the frame of which consists of two parts connected to each other by a hinge mechanism. The motor is usually installed at the front. The frame itself is welded from channel steel. It consists of the following elements:
- traverses - front and rear elements of semi-frames;
- spars - side elements.
To make semi-frames, it is advisable to find a channel No. 9 - 16. As a last resort, No. 5 will do, but such a structure will have to be reinforced with transverse beams. The half-frames are connected to each other by a hinge mechanism. Cardan shafts from a GAZ-52 or GAZ-53 are ideal for these purposes.
Folded DIY homemade tractor It is better to equip a 4x4 with a four-stroke gasoline or diesel engine.
The motor can be taken from a Zhiguli or Moskvich.When using the M-67 engine, it is necessary to increase the transmission ratio. In addition, effective cooling needs to be done. Otherwise, the motor will overheat, which will affect the loss of power and rapid wear of parts.
Installation of working units for fracture
For the tractor transmission, it is advisable to get a PTO, clutch and gearbox from a domestic GAZ-53 truck. In order to connect these units to the motor, they will have to be upgraded. For example, to connect the clutch to the engine, you will have to make a new basket. It must be suitable in size and fastenings. The rear part of the flywheel is shortened on a lathe, plus a new hole is drilled in the center.
The front axle is simply transferred from another vehicle. There is no point in changing its design. But the rear axle will also have to be slightly modernized. This unit is similarly removed from another car, but the axle shafts are shortened before installation. The rear axle is secured to the frame with four stepladders.
The choice of wheel size depends on what work the tractor will perform. To prevent equipment from burying itself in the ground, it is optimal to install wheels with a radius of at least 14 inches on the front axle. In general, if the tractor is needed only for transporting goods, then wheels with a radius of 13 to 16 inches are suitable. For extensive agricultural work, it is advisable to choose wheels with a large radius - from 18 to 24 inches.
It is not possible to make hydraulic cylinders for the control system yourself. They are removed only from old decommissioned equipment.To maintain operating pressure and oil circulation, a gear pump is installed. At the break, it is desirable that the gearbox be connected to the wheels of the main shaft and control them.
The driver's seat is suitable for a passenger car. The chair is soft, comfortable, plus there is a mechanism for adjusting the backrest tilt. The height of the steering wheel is made comfortable for the operator. The driver should not cling to it with his knees.
Assembled from old spare parts, the breaker in plowing should produce about 2 thousand revolutions. The minimum speed is 3 km/h. Such parameters are achieved by adjusting the transmission.
In this tractor design, it is good to install a separate gearbox and a four-section hydraulic distributor on each drive wheel. Then there is no need to install a cardan and rear axle differential.

A homemade tractor is easy to maintain, since the owner knows what he has installed and where. Load the unit only after complete running-in.
