Controlling the hydraulic system and
mounted attachment without power
governor
On the tractors without power governor,
the mounted attachment is controlled by
means of the rightmost handle of the dis -
tributor.
When operating the mounted machines,
use handle positions “lift” and “floating” on -
ly.
It is forbidden to put the handle to posi -
tion “lowering” when operating mount -
ed tillage machines!
Only use the “lowering” position when
controlling the external cylinders in-
stalled on the machine and designed for
adjusting the position of working units
(such as a reel, header, opening
ploughs, etc.) of harvesting, sowing and
other machines. If the distributor handle
does not automatically return to the
neutral on completion of the cylinder
movement, do it manually. And vice
versa, in case of earlier return of the
handle, hold it by the hand until the op-
eration is completed.

Power control
Using the power control ensures the best
improvement of the productivity when per-
forming the power intensive agricultural
operations, such as tillage, deep opening
and cultivation when operating the tractor
with mounted agricultural machines.
When tilling with the ПНЗ-35Б and ПЛН-
3-3 5 ploughs, lift the plough support wheel
to the uppermost position.
When ploughing at small depth (less than
2 0 -23 cm) under conditions, where the soil
density along the run length varies consid -
erably (sand – clay), lower the support
wheel to limit the maximum depth on the
plots with low soil density.
When performing the continuous cultiva -
tion and deep opening in case of unitiza -
tion of the tractor with agricultural ma -
chines with two support wheels within
takeover width measurement plane, put
the support wheels to the required height
to exclude lateral warps of the agricultural
machine, uneven loads on the outermost
(right and left) driven elements.
