How to make a mini tractor from a Neva walk-behind tractor with your own hands

Manual labor on the garden plot is tiring, so the owners try to mechanize it whenever possible. First, a person buys a walk-behind tractor or cultivator... But over time, such equipment becomes not enough to complete the assigned tasks, and the owner begins to re-equip it. For example, now we will consider how to assemble a mini-tractor from a Neva walk-behind tractor with our own hands and find out what is needed for this.

What is needed to convert the "Neva" MB-23S walk-behind tractor into a mini-tractor

Before you learn how to make a mini-tractor out of a Neva walk-behind tractor, let's figure out what will come of it and what parts are needed. To begin with, as a result of the conversion, you will have a four-wheeled vehicle. In addition to performing all operations for processing the garden, on homemade mini-tractor you can transport goods, maintain a home farm, take care of the garden. To expand the functionality of the unit, you will have to buy attachments. For example, if you attach the blade to the front of the frame, then in winter you can remove the accumulation of snow from the territory adjacent to the house with a mini-tractor.

For quick assembly of the tractor, special kits are sold. The kit contains all the necessary spare parts. If you really want to save money completely, you can find old parts from a passenger car. You will have to tinker with them longer, making the fit, but such a mini-tractor will pay off faster due to the low cost.

The model "Neva" MB-23S was not accidentally chosen as an example. The walk-behind tractor is equipped with a 9-liter four-stroke diesel engine. from. Thanks to the high tractive power of the engine, it will be possible to assemble a high-performance mini-tractor. The unit has enough power to work with many types of attachments.

So, for reincarnation, you need a working walk-behind tractor, a steering column, bearings, a wheelset and, of course, metal. The frame is usually welded from a channel, profile or pipe. To strengthen important nodes, you will need a corner and sheet steel with a minimum thickness of 5 mm.

Maneuverability, stability and productivity depend on the correct manufacture of the undercarriage. homemade unit. When assembling mini-tractor from a walk-behind tractor Neva, it is advisable to pick up wheels with a radius of 14 to 18 inches. Small wheels will cause the vehicle to tip over in difficult terrain, while large wheels will make it difficult to control the machine.

Advice! For the conversion of this model of a walk-behind tractor into a mini-tractor, wheels from a Volga car are well suited.

We start modernizing the walk-behind tractor

So, we figured out what we need for work. Now it's time to consider in detail how to make a mini-tractor from a Neva walk-behind tractor with your own hands.

During work, there should always be a diagram at hand, which indicates all the nodes and dimensions of the workpieces. If you have already decided, then let's proceed:

  • Guided by the drawing, the blanks for the frame are cut with a grinder. The main load will fall on the structure, so it must be made strong. The frame elements are connected by welding. For reliability, complex joints are reinforced with a bolted connection. A center-welded jumper will not interfere. It will increase the frame's resistance to deformation when transporting heavy loads off-road. Remember to weld attachment mountings right away when making the frame. This will be more difficult later on due to limited access.
  • The frame for a mini-tractor can be solid and broken. If the choice fell on the second option, then a hinge is needed. This piece connects two half-frames.But then the steering column is also installed at the fracture of the two frame parts.
  • The assembly order of the chassis depends on the location of the motor. If it stands in front of the frame, then the track width remains native, as it was on the walk-behind tractor. The rear wheelset is fixed to the frame on the axle. It is made from a piece of thick steel bar or pipe. To mount the wheels themselves on the axle, you will need hubs and bearings.
  • If the motor is installed on the rear of the frame, then the native wheels from the walk-behind tractor are attached to a wider bridge. Otherwise, the narrow track will affect the poor balancing of the mini-tractor.
  • The steering control of a home-made unit can be assembled from the native handles from the walk-behind tractor. But such a design will create discomfort when you need to take the tractor back. The best option is to install a traditional steering column.
  • With a one-piece frame construction, the rods from the column are connected to the front axle. It is she who will turn with wheels. On a broken frame, the column pivots the entire front end with axle and wheels. In this case, you need to use two additional gears: one part is capitally fixed to the element of the front of the frame, and the other is attached to the steering column.
  • The driver's seat is welded to the frame on racks. This is where you might think of floating mounts to allow for workplace adjustments. If it is supposed to work on a mini-tractor at night, you need to install two headlights, and to move on the highway, you will need to add side lights. Only for the lighting to work, a battery is installed separately, since the walk-behind tractor does not have an outlet for connecting headlights.

At the end of the assembly, the mini-tractor must be run in without load. If errors are detected in the calculations, the defective units are corrected, otherwise this technique will not work for a long time.

The video provides an overview of the mini-tractor from the Neva walk-behind tractor:

And now we propose to look at the photo drawings that will help in reworking the walk-behind tractor. The diagrams show a structure with a solid and broken frame.
