Homemade mini tractor from motoblock: step by step instructions

Many farmers who have small plots of land, use converted tillers in the role of a tractor, as the purchase of a full-fledged machine will not be justified in a decade. How rational is the conversion of the motoblock to a mini-tractor, how to make and use such a device, you will learn from this article.

Possibilities of the device in the garden

Depending on the design and your needs, a mini tractor on the basis of the motoblock can be used for snow removal, soil loosening, cargo transportation, planting potatoes or other crops.

However, it is worth remembering that the capabilities of a mini-tractor directly depend on the proper construction of the entire structure and the power of the motor-block itself.

You can use the device as an ATV. Such a device will have excellent maneuverability and throughput, but the speed of movement leaves much to be desired. Many craftsmen are building snowmobiles on the basis of the motoblock and other interesting machines that help with the housework and in some cases are more useful than a full-fledged bulky tractor.

How to choose a walker for homemade

Most difficult - choose a walk-behind tractor, since you need to buy not only a powerful enough unit, but also to invest money wisely.

Let's start with power. If the tractor from the motoblock is used for plowing or loosening the soil, it is necessary to proceed from the size of your plot.

For the plot from 20 to 60 acres 4 l engine will do. with. (better with a little margin). With 1 hectare handle motoblocks for 6-7 "horses." From 2 to 4 hectares of land it is reasonable to work with a machine from 8-9 l. with.

Manufacturer. If you grow products not for sale, it is worth staying on cheap domestic motor-blocks, which, although they break often enough, but replacing parts does not empty the wallet.In the case when the grown products are sold and the breakdown can thwart all the plans, purchase German cars. Remember that any equipment will break down sooner or later, but unlike domestic motoblocks, it is difficult to find spare parts for the "Germans", and they are very expensive.

Equipment. This item is very important, because depending on the work, the presence of one or another additional device will save you time to search and purchase in a short time.

Many tillers come with a huge number of "lotions", which at a cost can exceed the unit itself. If you do not need a set of additional tools, better buy a more powerful machine for less money. Functional. We recommend buying a walk-behind tractor that has the following built-in functions: steering wheel adjustment (a mandatory function, since you need to adjust the height to the overall design); emergency stop of the engine (will help to quickly turn off the unit in case of emergency); electric starter (needed for powerful diesel engines).

Other features. Other features include the distance between the wheels, the diameter of the wheels, the shape of the unit. In order for a homemade tractor to be stable enough, you need to choose a walk-behind tractor with the greatest possible distance between the main wheels. In the opposite case, your car may simply fall on the turn. The permeability depends on the diameter of the wheels, so if you have heavy clay soils in your area or high humidity in the region, choose a block with a large wheel diameter.

For dry moderately loose soil suitable unit with an average diameter of the drive wheels. The initial form of the unit must be such that it can be easily connected to the frame and the rear wheels. It is better to prefer the "square" units, rather than elongated in length.

Selection of materials for production

We recommend to re-equip the motoblock into a mini-tractor using a special kit, which consists of all the necessary parts to create your tractor,namely: a frame with mounts for the engine, a seat, footboards with pedals, steering with rods, levers for locking the axles, a front beam with brake disks and wheel hubs, a rear linkage with a manual lifting mechanism. This set of equipment will cost you in 350-400$but it is worth the money. All materials are made of metal and are of good quality. The kit solves the problem with some spare parts that cannot be done manually, as they require "jewelry" work.

If this solution does not suit you, you can make the frame, seat and frame with your own hands, and buy the rest in a specialized store.

You will need steel profiles for the frame, a suitable seat, a pair of wheels, consumables (bolts, nails, studs).

What you need from the tool

The main tools that will be needed to assemble the structure: a welding machine, wrenches, a drill, a Bulgarian, pliers, a hammer, gloves. A small list of basic tools due to the fact that, depending on how you see your homemade tractor, you may need some additional tools or spare parts.

For example, if you want to make upholstery of the frame with any material, you will need a construction stapler and inserts on which the material will be attached.

Instructions with drawings

We turn to the process of creating a mini-tractor from the motoblock. Step by step, consider creating all the main parts manually.

Frame and body

To begin with, we need a good drawing that will meet all the requirements and at the same time be correct and balanced. That is, you need not just to draw something beautiful, but to make calculations based on a drawing that show whether the technique will be stable and powerful enough or not. If you have the necessary knowledge and skills, make a drawing and start assembling the parts. If you have never dealt with drawings before and are not well versed in technology, invite friends to make a drawing based on the sample below.

The drawing corresponds to a self-made tractor on the basis of the Bison motor-block.

With the drawings figured out, now let's move on to the creation of the frame and body.

From steel profiles you need to make a frame that must be stable and withstand the additional load. To connect the corners of the frame, bolts and a drill should be used. Then the frame must be welded using a welding machine.

The most optimal material for the creation of the body is considered to be stainless steel sheet. Side height - 30 cm.

Seat and steering gear

The seat may be different, but it is best to take it out of the car. To control tiller you need a steering wheel. First you need to attach the hinge.

In this case, when turning the steering wheel, it will not be the wheels that turn, but the knot itself, which will connect the walker tractor and the tractor. The height of the steering wheel. Once you have attached the driver's seat, sit on it and adjust the height of the steering wheel for yourself.

Wheels

If you want to save a little, use the old wheels of the car. However, in this case, they will interfere during the field work. The optimum diameter of the front tires - 12 to 14 inches.

If you take the wheels with a diameter of up to 12 inches, your walk-up tractor will sink during operation, and if it is more than 14, it will be more difficult to control the unit. Tires must be specially selected for the use of motorblock.

Fastening (coupling)

Coupling can be made of stainless steel pipe. So it will serve you for many years. But you can save time by buying a mount in the store.

The hitch is attached to the steering rack area.

How to quickly get a homemade tractor from the motoblock (trailer adapter)

The trailer adapter is a trailer with a removable body, which is altered in the form of additions to the walk-behind tractor. With it, you can produce a variety of agricultural work. This is considered a mini tractor. To create an adapter, you need a uniaxial frame design. Used elements of the suspension of a motorcycle stroller. For the axis you need to find a steel corner with dimensions 40x40x2.

Cutting it, we weld the wheel hubs, checking their correct location and reliability. Then install the wheels.

After that, the axis is substituted to the motoblock and measure the length of the mounting pipe. Equally important is the manufacture of mounting for the seat. This element depends on the design.

The optimum knee size (for lowering or raising the hitch) is 30x50x20 cm.

To reinforce the adapter, weld additional pipes in the form of a rigid frame measuring 30x30 mm. On the axis, which is attached to the walker, weld the steps of solid metal plates. The size and attachment point depend on the growth of the worker.

As you understand, making a mini-tractor with your own hands is not so difficult. The main thing is to follow the instructions for making.
