Position control
When applying the position control, the
power governor of the hydraulic system
ensures the automatic keeping of the
specified position of the agricultural ma-
chine relatively to the tractor frame.
It is recommended to use the position con-
trol during the soil cultivation by using
mounted ploughs and cultivators for con-
tinuous and multi-row tilling, as well as
during the deep opening under the condi-
tions of even field relief.
When operating the wide-cut machines
unitized with the tractor in the position
control mode, it is necessary to use the
support wheels for excluding the lateral
warps of the agricultural machine, improv-
ing the linearity of the unit motion and cre-
ating the better conditions for imitating the
relief in the lateral direction (relatively to
the tractor motion).
To prepare the implement for operation in
the position control mode, proceed as fol -
lows:
1 . Connect the machine to be mounted
with the hitch of the tractor.
2 . Lift the mounted machine to upper
(transport) position.
3 . Switch to the position control mode. To
do this, move the switch (3) to the slot of
the position lever (1) turning it to the right
(in the direction of the tractor motion) to
position I.
4 . Turn the correction rate handwheel (2)
counter-clockwise to the stop, setting the
maximum lifting rate for automatic cor -
rections of the position.
