Operation:

If you move the lever up to position 1, one-way functioning hydraulic cylinder on the implement
is supplied with oil under pressure, and the hydraulic cylinder starts to rise. When you release it,
the lever on the control element automatically returns to neutral position 0. Hydraulic cylinder
remains on lift position.

If you move the lever down to position 2, you release oil flow from one-way hydraulic cylinder
back to hydraulic system of the tractor. Cylinder on the implement, with the help of external force
or built-in spring (depending on version), starts to lower.
Even when you release, the lever stays fixed in position 2 (DETENT). Therefore, you must always
shift it to position 0, if you want to cancel lowering of lift mechanism.
CONTROL OF REAR HYDRAULIC LIFT MECHANISM
Control lever D
Control lever redirects oil from pressure circuit through two-way functioning 6/4-directional control valve
(version B) directly to both two-way functioning hydraulic cylinders simultaneously, to control external
rear hydraulic lift mechanism.
Operation:

If you move the lever up to position 1, lift mechanism rises. When you release it, the lever on the
control element automatically returns to neutral position 0, and the lift mechanism remains in this
lift position.

If you move the lever down to position 2, lift mechanism starts to lower. When you release it, the
lever on the control element automatically returns to neutral position 0, and the lift mechanism
remains in this lift position.

As the control valve also functions as blocking device (DETENT), you can also move the lever to
position 3. When you release it, the lever remains fixed in position 3. Therefore, you must always
manually move it to position 0, if you want to cancel lowering mechanism.
When the control lever is in position 3, with completely lowered lift mechanism, implement shifts to float
position, so that it can adapt to the ground.
