The hydraulic system is intended for lifting and lowering of agricultural machines and implements attached in
the rear three point hitch.
Hydraulics control panel
Hydraulics control panel is located in the area of the right wing.
Controlling the rear three-point hitch is enabled by the inner hydraulic circuit (1).
Controlling outer hydraulic circuits (couplers) is enabled by outer hydraulic circuit (2).

Ways to regulate inner hydraulic circuit

Hydraulic system allows of three ways to regulate the lifting of the rear three-point hitch:
Position regulation (img. 1) - the tool connected to the rear three-point hitch is automatically kept in the same
height (position) with regard to the tractor.
Mixed regulation (img. 2) - a combination of position and power regulation. Suitable mainly for tilling areas of
different soil resistance.
Power regulation (img. 3) - the tool connected to the three-point hitch is automatically being adjusted
depending on changing soil resistance.
All the regulations can also be used when working with a tool equipped with a support wheel in so-called free
(floating) position.
