Belarus 80.1 Operation Manual page 85

At the start of the run of cultivated land lower mounted implement, by turning handle
2 (figure 2.28.11) forward. The further forward the handle is set, the greater depth of tillage
will be. When you shift handle 2 towards yourself the depth will decrease. After adjusting
to the desired depth, shift stroke limiter 1 along the groove of the control console until it
stops against the handle and lock it.
At the end of the run of cultivated land to raise the implement set handle 2 to the
position "lifting" – backwards until it stops. After lifting the handle has to automatically re-
turn to the neutral position "N".
At the start of each subsequent run lower the implement by shifting handle 2 for-
ward until it stops against stroke limiter 1.
While working on ploughing in cases, when draft control handle is set forward for
the maximum depth, the obtained depth is insufficient, reinstall upper link 2 of the mounted
implement on the middle hole of clevis 1 (position "Б" in figure 2.28.12);
When you install upper link, adjust correction speed handwheel and select hole in
the clevis for specific soil conditions and each type of agricultural implements. No read-
justments are required during operation.
When using position control method draft control automatically maintains the set
position of the agricultural implement relative to the tractor frame. Use of position control
for soil cultivation with mounted ploughs, tillers for overall and inter-row cultivation of soil,
as well as for deep cultivation is recommended in the conditions of smooth field relief.
On wide-cut machines, coupled with tractors, when working in the position control
mode, supporting wheels should be used in order to avoid transverse wracking of agricul-
tural machines, to improve directness of the implement and to create better conditions for
contour following in transverse (relative to tractor travel) direction.
When preparing the implement for operation with the use of position control method
proceed as follows:
- mount upper link 2 (figure 2.28.12) of the mounted implement on the upper hole of
clevis 1 (position "A" in figure 2.28.12);
- connect mounted implement (machine) to tractor RLL;
- if required adjust the RLL and mounted implement.
- switch on position control method, to do this raise mounted implement (machine)
in the upper most position and get switch 4 into the groove of position lever 6 by turning
the switch to the right (along the tractor) into position "I". To facilitate switching before get-
ting into the groove shift switch forward (along tractor travel) until it is aligned with the
groove on lever 6;
- turn correction speed handwheel 3 anticlockwise until it stops, setting maximum
lifting rate for automatic position correction.
At the start of the run of cultivated land set the implement to the desired position.
Lowering is done by shifting handle 2 (figure 2.28.11) forward. The further forward the
handle is set, the lower the implement will be brought down. After setting the implement to
the desired height position shift stroke limiter 1 until it stops against the handle and lock it.
At the end of the run of cultivated land to lift the implement in transport position turn
handle 2 towards yourself until it stops. After lifting the handle has to automatically return
to neutral position "N".
At the start of each next run lower the implement by shifting handle 2 forward until it
stops against stroke limiter 1.
