OPERATION OF 3-DIRECTIONAL VALVE
On rear hydraulic lift mechanism of the tractor, it is possible to transform two-way hydraulic cylinder into
one-way with additional three-directional control valve, which is fitted to the right of the driver's seat.
To transform to one-way functioning of hydraulic cylinder, move the lever on valve to position A.
To transform to two-way functioning of hydraulic cylinder, move the lever on valve to position B.
4.7.9
CHOKE OF REAR HYDRAULIC CYLINDERS
For different work requirement, the tractor also enables setting speed of movement of hydraulic cylinders
on rear lift mechanisms. This is ensured by two chokes, installed on the right side below control elements.
Chokes regulate amount of supplied oil into hydraulic cylinder. One choke is for setting speed of lifting,
and the other choke for setting speed of lowering rear hydraulic lift mechanism.
Operation:
Lifting or lowering
By turning the choke to the right (+), you are
closing oil supply into hydraulic cylinders
(choke – speed of cylinder movement is
reduced);
By turning the choke to the left (-), you are
opening oil supply into hydraulic cylinders
(speed of cylinder movement increases).
