LEVER OF OPTIONS OF REGULATION
The lever has three positions marked P, M, D.
P - Indicates a position regulation when the implement, attached in the three-
point hitch, is held automatically at the same level (position) to the tractor.
M - Indicates a mixed regulation that is a combination of position and force regu-
lation. It is suitable in particular for ploughing on lands with varying soil resis-
tance.
D - Indicates a force regulation, where height of the implement, attached in the
three-point hitch, is adjusted automatically depending on the soil resistance.
All regulations allow work with the implement that is equipped with a supporting
wheel in the so-called free (floating) position.
For transport of an implement it is necessary to move the selection lever to
position P!
LEVER OF SPEED OF RESPONSE
This lever controls the cock in the distribu-
tor that distributes flow of oil to the internal
and external circuits.
When the lever is moved towards the
driver’s seat (MIN), flow of oil is reduced
to minimum.
Restriction of flow of oil with force or
mixed regulation decreases speed of re-
sponse of the hydraulic device, e.g. with
ploughing under different soil conditions.
