How to make hydraulics on a tractor yourself
Equipping the tractor with hydraulics, they improve their control and increase productivity. Its presence allows you to expand the range of attachments.
Begin by charting. Focusing on it, components are purchased. Some of the craftsmen make the valves themselves, which can significantly reduce costs. Most craftsmen purchase a finished unit in a store or borrow from other equipment. Further work includes: installation of hydraulics, its connection; node calibration; system operation check.
The hydraulic system on the tractor consists of: a tank with oil; engine; hydraulic pump; directional control valve; hydraulic motors and pistons; connecting hoses. Additionally, it can be equipped with: filters; pressure sensors; other auxiliary elements.
When compiling the scheme, some recommendations are taken into account. The hydraulic pump must be located under the oil tank. This will ensure free flow of oil to it, eliminate problems at startup. The device must have sufficient power to operate all components of the tractor equipment.
The control valve is purchased separately or equipped with levers. A group of pistons stands out under each lever. For some tractors 2 ... 3 levers are enough: one provides braking; the second is raising / lowering the frame; the third - includes hydraulic motors. If there is a bucket in the attachments, then a distributor having additional functions is purchased.
When choosing a hydraulic pump, the pressure by which the hydraulic motor starts is taken into account. If not enough, it simply won’t start working. The amount of oil that it can pump is also important - this affects the speed with which operations are performed.
Having prepared the components, they assemble the hydraulic system on the tractor. The process is simple. First, the engine is connected to the hydraulic pump, the task of which is to constantly "drive" the oil through the system. The output tubes from it are connected to the control valve.
Outgoing hoses from the distributor are connected to equipment (pistons, motors), a hydraulic tank. The location of the filter is the pump-tank section.
After completing installation work, they proceed to check the equipment. In the absence of problems, complaints, you can begin testing the tractor in operation. Correct the operation of the steering hydraulics, adjusting it to movement. The steering system must not have a floating state.
