Alteration of walk-behind blocks is most often done in order to create a car resembling a mini-tractor. This allows you to optimize the processing of the land and accelerate 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 expensive.
Criterias of choice
If you plan to remake motor blocks in advance, then before purchasing a car you need to consider a number of factors:
- Power indicator. This parameter should be commensurate with the type of soil and the size of the territory intended for processing.
- Fuel. As practice shows, it is preferable units operating on diesel fuel. They are more powerful and more economical than gasoline versions, have a greater working resource.
- Unit weight. When choosing, it is worth considering this factor. If the technique is focused on use as an individual household tool, you should focus on light models. For more serious operation, massive modifications are chosen, since they are intended for multifaceted soil treatment.
- Cost. Not always an expensive walk-behind tractor will become the optimal base for the future mini-tractor. However, the alteration of walk-behind blocks involves the use of high-quality parts that have 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 blocks are suitable:
- Agro.
- MTZ.
- "Neva".
- "Bison".
- "Centaur".
For the alteration of 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 the Agro technique has some design flaws. The main one is the low tensile strength of the axis. This parameter does not affect the functionality of the walk-behind tractor, however, when remodeling 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", "Bison"
The centaur motoblock is ranked as an agricultural technique of a professional direction. 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. A kit for modifying a walk-behind tractor includes a metal profile frame, an extra pair of wheels and a driver's seat. The resulting equipment can be supplemented with a towing cart, plow, blade and other attachments.
As confirmed by the reviews, comments, suggestions for alteration of the Agro walk-behind tractor will require a more serious approach. It will be necessary to strengthen the drive axles with gear wheels.
To implement the Zubr motor-block into a mini-tractor, the following elements will be required:
- Hydraulic assembly for operating attachments.
- Extra two wheels. You can borrow them from a passenger car.
- Brake system and steering column.
Assembly guide
Modification of the walk-behind tractor into a tractor begins with the preparation of the necessary parts and tools. Ready-made kits are available for this procedure. The cost of such a set starts from 30 thousand rubles.
Required Tools:
- Welding unit.
- Drill.
- Set of drills.
- The keys.
- A set of screwdrivers.
- Saw type grinder.
- Fasteners.
Before starting work, you should perform a diagram or drawing of the proposed facility. This will avoid design errors and save time. Then you can proceed with the assembly.
Frame part
First you need to strengthen the bearing part by mounting an additional pair of wheels. From materials you will need corners or a pipe made of metal. The cross-section of the workpiece used must correspond to the expected loads. Do-it-yourself alteration of a walk-behind tractor by cutting frame blanks with the help of a “grinder” into pieces of the required length. The elements are interconnected by bolt fastening or welding.
It is advisable to immediately install on the frame a fixture for additional attachments. The design can be fixed both on the front and rear. A welded tow bar allows you to work with trailers.
Running system
The kit for modifying a walk-behind tractor includes two ready-made hubs for the front wheels. The frontal pair is fixed using a metal pipe corresponding to the axial width, and the hubs are attached to it.
In the center, holes are made that serve as access for fasteners 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 sleeve. A pulley is placed on the part, which serves to transmit torque from the power unit.
Motor
As a rule, the engine is mounted on the front frame of the frame. This allows a homemade mini-tractor to maintain the required balance when working with trailed devices. An attachment system must be created at the motor mounting location. The power take-off shaft should be placed parallel to the pulley axis on the rear axle of the equipment. The betraying moment is carried out by means of a belt drive.
Other equipment
After assembling the main structure, the brake unit and the hydraulic distributor interacting with the attached equipment are mounted. In the case of moving equipment on general roads, it is reasonable to install headlights and cornering signals.
To give the car originality and aesthetics, you can equip it with casing, sun visors and other exterior elements. After running in the tractor, check it when working on the field or in the summer cottage.
Modifications based on MTZ
The conversion of heavy walk-behind tractors 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 shift of the center of gravity to the front during operation. This does not have a very positive effect on the work process. The problem can be fixed as follows:
- The machine should be put into operation with the mower.
- The front platform is completely dismantled.
- The front motorcycle wheel with bolts, as well as the steering wheel, is placed on the vacant seat.
- In the grooves of the steering link, an adjusting link is fixed, the functionality of which is to give the structure additional rigidity.
- The mount for 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 at the rear.
- A hand brake is equipped on the front wheel.
We make an all-terrain vehicle
It is quite possible to make a swamp or snowmobile from a walk-behind tractor. They have an almost identical design. It is important that the equipment has minimal pressure on the soil. This will require the use of specific wheels with a wide profile. Suitable wheels are low-pressure wheels or parts of tracked tracks, for example, from the Buran snowmobile. Such a solution makes it possible to place standard automotive analogues in the elements. After inflating the tires, the lugs dig into them tightly.
ATV
It’s quite possible to build an ATV from a walk-behind tractor. He will not have the power and characteristics of this analogue, but will improve the maneuverability and maneuverability of the equipment. Landing on such a machine will not be a motorcycle, but an automobile type. Special wheels do not need to be done. 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 means of transportation. In this case, the selection of materials and time costs will not particularly affect the financial budget and time costs.
In conclusion
A modern walk-behind tractor is an indispensable thing for farmers, summer residents and other agricultural industries. Its application significantly facilitates labor costs, saves time and improves the quality of harvesting. A variety of attachments are provided for such an assembly. In addition, alteration of the walk-behind tractor to a mini tractor with its 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 cargoes or cleaning the territory from snow.
