[2]  REAR HYDRAULIC BLOCK

The rear hydraulic block is equipped with cylinder safety valve (1), lowering speed adjusting valve (2) and check

valve (5), etc. besides hydraulic outlet port.

The hydraulic outlet port is located top of the rear hydraulic block to take power out from the tractor to operate the

hydraulic cylinders on the implement.

[3]  POSITION CONTROL VALVE

Neutral

Pressurized  oil  flows  at  the 

P

  port,  pushes  open

unload poppet 1 (4) and returns to tank from 

T1

 port.

The oil in the chamber 

A

 behind the unload poppet 1

(4)  returns  to  the  tank  from 

T4

  port.  The  oil  in  the

hydraulic cylinder does not flow out because the circuit

is cut off by the actions of poppet 2 (1) and check valve

in the rear hydraulic block.

This  allows  the  implement  to  be  kept  at  a  steady

height.
