How to do hydraulics on a single axle tractor with your own hands: installation NSH-10 and NSH-16

Hydraulics on a single-axle tractor will increase the productivity of the mechanism, increase the reliability of the design and improve the management of the unit. Make hydraulics on a tractor with their own hands is not difficult, with this cope even a person who does not have special skills.

Let’s consider the advantages of a power tiller with a hydraulic drive:

  • simplified control;
  • The ability to connect attachments with a hydraulic drive: seeders, mowers, devices for harvesting;
  • improvement of brake system.

Potato harvester to the tiller with his hands

This type of attachment greatly facilitates the harvesting of potatoes, as well as other tuber crops.

The main structural elements of the potato harvester are:

The strap, the moving part of the potato digger, is made of steel rods and one or more pointed steel plates. The sharp edges and ends of the ploughshare structural elements are blunted to prevent damage to the potato tubers.

To make the welded frame, you need a metal angle of about 60×40 mm, a shaped tube and a section of channel bars. The frame’s dimensions and weight, which depend on the weight of the materials used and the specific design solution adopted, must match the dimensions and power of the potato harvester.

The redaction unit is the main element of the potato harrow. For its manufacture, you will need two metal cylinders, which will act as cups for connecting sleeves. with such a design provides the interaction of the drive and driven shafts. Next, you need to make a metal pipe 25 mm in diameter hubs, which are welded to the transmission sprockets. The latter are mounted on bushes with the aid of prismatic keys.

The most complex part of the potato harvester is the cleaning drum. Its design includes a pair of roller chains with 94 links each, which are dressed on special rods. This element, called the “squirrel wheel”, is fixed on two fixed axles, which ensures its mobility in rotation. So the force of the motor shaft shaft of the potato ploughshare, attached to the moving casing, will change the angle, making digging movements during the movement of the power tiller.

The angle of inclination of the working part and the depth of the dig are adjusted by means of a slider. It is made of fluoroplastic, and its parameters are selected according to the characteristics of the main unit (engine power, travel speed, etc.).д.), as well as the properties of cultivated soil.

Design features

Before proceeding to the manufacture of a homemade sprayer, it makes sense to familiarize yourself with the basic requirements that apply to this type of equipment.

Any sprayer, regardless of design, must meet the following criteria

  • droplet size. The spray of chemicals should be fine to avoid burns to the plants. It also helps to control the amount of liquid used.
  • Uniformity. Pesticides must cover the plants evenly to ensure the quality of the treatment.
  • Distribution. The spray liquid should be evenly distributed, regardless of ambient conditions, planting frequency and row spacing.
  • Flow rate. The quantity of liquid consumed should not depend on the concentration of the liquid.
  • Convenience. The capacity of the drum should match the length of the runs, this will ensure better performance. In addition, the equipment must be easy to store and operate.

The main thing is to prevent the sprayer from damaging the plants while in motion. This does not apply to the factory models. here each element is calculated by specialists. But it is worth paying attention to this nuance when making it yourself.

Sprayers are classified according to fluid consumption per treated hectare. According to this criterion, equipment is divided into four groups:

The last two categories are usually installed on power tillers and tractors. Having understood the basic provisions, let’s consider options for self-made.

Hydraulics on the mini-tractor, made by our own hands

If you decide to make a mini-tractor yourself, without a hydraulic system, such a design will not be considered a full-fledged agricultural machine. You can assemble the hydraulic unit with your own hands. Necessary elements can be removed from any old equipment.

The heart of any hydraulic system is the pump. This device keeps the fluid moving throughout the system. The hydraulic oil is fed into the pump from the oil tank. The pump itself is driven by a diesel engine, which is equipped with a mini-tractor. It is possible to use NSH-10 as a pump. The oil is pushed by the pump and drains through flexible hoses to the directional control valve.

To assemble this complex unit with your own hands is unlikely to work, so you need to remove the distributor from any broken-down tractor. The best option would be to use a P-80. These valves are installed on MTZ tractors.

After the distributor, oil flows to the hydraulic cylinder that is responsible for raising and lowering of the attached implement. The finished construction is installed on the frame of the mini-tractor as close to the drive axle as possible.

This design can be supplemented with hydraulic motors that are connected to the wheels. Such a scheme has certain advantages and is, in fact, a universal braking system.

When oil flows into the hydraulic cylinder, its level in the system drops and the wheels are braked. If you put the hydraulic control levers in the neutral position, the drive wheels are fully locked.

Installing the pump on a single axle tractor

Hydraulics on a single-axle tractor will increase the performance of the mechanism, improve the reliability of the design and improve control of the machine. To make the hydraulics on a single-axle tractor with their own hands is not difficult at all, even a person who does not have special skills can cope with it.

As half-axles with pivot pins in the cultivator right and left are mounted swivel posts. Then it’s necessary to synchronize the installation of wheel rims and discs. Their relative position must be offset.

After installation and connection check the work of the whole construction. If any parts are malfunctioning, all connections should be checked for leaks. Then, after eliminating all the shortcomings, once again turn on and check the performance of the power tiller with hydraulic control system. It is also necessary to adjust the operation of the steering and movement hydraulics.
