HYDRAULIC SYSTEM
2. POSITION CONTROL VALVE
Hydraulic system of this tractors is composed of main components as shown in the figure. This system has the
three functions as follows :
• To raise and lower the implement connected to the three point hitch.
For this motion, the position control valve (4) and the linkage installed on the hydraulic cylinder body provide three
difference applications : position control, draft control, and mixed control
• Takes out hydraulic power from the front hydraulic block assembly (2) to operate an implementís hydraulic
actuator.
• Takes out hydraulic power from the quick couplers (7) induced in the auxiliary control valves assembly (6) (if
equipped) for the implements with actuators. In this case, the implement's cylinders can be actuated by operating
the auxiliary control valves.
