HYDRAULIC SYSTEM
4. THREE POINT HITCH HYDRAULIC SYSTEM
[1] THREE POINT HITCH HYDRAULIC CIRCUIT
W1013426
1. When the engine is started, the hydraulic pump 1 (7) is rotated to draw oil from transmission case (9) through the
suction pipe.
Supplied oil is filtered by the hydraulic oil filter (8).
2. Filtered oil is forced out by the hydraulic pump to the auxiliary control valve (5) through the front hydraulic block
(11).
3. With the auxiliary control valve (5) in neutral position, oil is channeled from
“N”
port to the control valve (1).
4. The hydraulic system has a relief valve (10) which restricts the maximum pressure in the circuit.
The hydraulic cylinders (2) have a cylinder safety valve (3) to relieve shock pressure due to heavy implement
bounce.
5. The control valve (1) is actuated by the mechanical linkage for
“Position control function”
.
