Alteration of motor blocks is most often done in order to create a machine that resembles a mini-tractor. This allows you to optimize the process of processing the land and speed up the speed of various operations, along with their expansion. In addition, such a solution allows you to save money, since buying a factory model will cost an order of magnitude more.
Selection criteria
If you plan to remake walk-behind tractors in advance, then a number of factors must be considered before purchasing a machine:
- Power indicator. This parameter should be commensurate with the type of soil and the size of the area intended for processing.
- Fuel. As practice shows, units operating on diesel fuel are preferable. They are more powerful and economical than petrol versions, they have a longer working life.
- Unit weight. When choosing, this factor should be taken into account. If the technique is focused on use as an individual household tool, you should stop at light models. For more serious operation, massive modifications are chosen, since they are intended for multifaceted soil cultivation.
- Cost. Not always an expensive walk-behind tractor will become the optimal base for a future mini-tractor. However, the alteration of walk-behind tractors implies the use of high-quality parts with a long working life. Therefore, it is better to pay attention to trusted brands.
Features
Among domestic units for transformation and improvement, the following brands of walk-behind tractors are suitable:
- Agro.
- MTZ.
- Neva.
- Zubr.
- Centaur.
To convert motoblocks of these brands, it will not be difficult to find ready-made kits that allow you to quickly and efficiently convert the unit into a small tractor.
Among these types, only Agro equipment has some design flaws. The main one is the low fracture strength of the axis. This parameter does not affect the functionality of the walk-behind tractor, however, when converting it into a mini-tractor with your own hands, this nuance causes an additional load on the connecting beam. In this regard, during the transformation, it will be necessary to strengthen the node in question.
Centaur, Agro, Zubr
Motoblock "Centaur" is classified as a professional agricultural machinery. It is great for transforming into a tractor. The result is a reliable machine with high performance and wide functionality. It is worth noting that the diesel engine of the unit produces 9 horsepower. The motoblock conversion kit includes a metal profile frame, an additional pair of wheels anddriver's seat. The resulting equipment can be supplemented with a trailer, plow, blade and other attachments.
As confirmed by reviews, comments, suggestions for reworking the Agro walk-behind tractor will require a more serious approach. It will be necessary to strengthen the drive axles with wheel gears.
To convert the Zubr walk-behind tractor into a mini-tractor, you will need the following items:
- Hydraulic unit to operate attachments.
- Additional two wheels. You can borrow them from a car.
- Brake system and steering column.
Building guide
Alteration of a walk-behind tractor into a tractor begins with the preparation of the necessary parts and tools. Ready-made kits for this procedure are available for sale. The cost of such a set starts from 30 thousand rubles.
Required tools:
- Welding unit.
- Drill.
- Drill set.
- Keys.
- Set of screwdrivers.
- Saw type grinder.
- Fasteners.
Before starting work, you should complete a diagram or drawing of the proposed object. This will avoid design errors and save time. Then you can start assembling.
Frame part
First, you need to strengthen the bearing part by installing an additional pair of wheels. Of the materials you will need corners or a pipe made of metal. The cross section of the workpiece used must correspond to the expected loads. Alteration of the walk-behind tractorwith their own hands, they begin with cutting frame blanks with the help of a “grinder” into pieces of the required length. Between themselves, the elements are connected by bolting or welding.
It is advisable to immediately install a device for additional attachments on the frame. The design can be fixed both on the front and on the back. A welded towbar will allow you to work with towed devices.
Undercarriage
The motoblock conversion kit includes two ready-made hubs for the front wheels. The front pair is fixed with a metal pipe corresponding to the axial width, and the hubs are attached to it.
Holes are made in the center, which serve as access for fastening to the front frame. Then tie rods are installed, aggregating with the frame and column by means of a worm gear. The rear axle is mounted on bearings pressed into the bushing. A pulley is placed on the part, which serves to transmit torque from the power unit.
Motor
Normally, the engine is mounted on the front frame frame. This allows the homemade mini-tractor to maintain the required balance when working with trailers. A fastening system must be created at the place of installation of the motor. The power take-off shaft must be placed parallel to the pulley axis on the rear axle of the vehicle. The betraying moment is carried out by means of a belt drive.
Other equipment
After assembling the main structure, the brake unit and hydraulicdistributor interacting with attachments. In the case of moving equipment on public roads, it makes sense to install headlights and turn signals.
To give the car originality and aesthetics, you can equip it with trim, sun visors and other exterior elements. After running the tractor, check it in operation in the field or summer cottage.
Modifications based on MTZ
The conversion of heavy motoblocks into mini-tractors has its own characteristics. Consider the transformation of equipment based on the MTZ unit. It is equipped initially with a diesel engine with a pair of cylinders, which causes the center of gravity to shift to the front during operation. This does not have a very positive effect on the workflow. The problem can be fixed as follows:
- Machine should be set to mower mode.
- The front platform is completely dismantled.
- The front motorcycle wheel is placed on the vacant seat with the help of bolts, as well as the steering wheel.
- In the grooves of the steering rod, an adjusting rod is fixed, the functionality of which is to give the structure additional rigidity.
- Mounting under the driver's seat is fixed by welding.
- A compartment for the battery and hydraulic distributor is installed near the power unit.
- A steel platform for the hydraulic system is mounted on the back.
- The front wheel is equipped with a hand brake.
Make an all-terrain vehicle
It is quite possible to make a swamp or a snowmobile out of a walk-behind tractor. They have an almost identical design. It is important that the equipment has a minimum pressure on the soil. To do this, you will need to use specific wheels with a wide profile. As suitable elements, low-pressure wheels or parts of caterpillar tracks, for example, from the Buran snowmobile, are used. This solution makes it possible to place standard automotive counterparts in the elements. After the tires are inflated, the lugs bite into them firmly.
ATV
It is quite possible to build an ATV from a walk-behind tractor. It will not have the power and characteristics of a real analogue, however, it will improve the maneuverability and maneuverability of the equipment. Landing on such a machine will not be a motorcycle, but an automobile type. No special wheels are required. It will be enough to choose suitable elements from a passenger car, which can be equipped with wide-profile passable rubber. If desired, the walk-behind tractor can be converted into various vehicles. At the same time, the selection of materials and the time spent will not particularly affect the financial budget and time costs.
Finally
Modern walk-behind tractor is an indispensable thing for farmers, summer residents and other agricultural industries. Its use greatly facilitates labor costs, saves time and improves the quality of harvesting. For such a unit, various mountedfixtures. In addition, converting a walk-behind tractor into a mini tractor with your own hands is possible at minimal cost. The equipment will be useful at all times of the year, from planting or harvesting, ending with the transportation of various goods or clearing the territory of snow.
