Figure 2.28.11 – Operating elements of draft control with the possibility of draft, position
and depth control of agricultural implements position
Handwheel of correction speed control 7 serves for adjustment of agricultural implement
position correction speed during tractor operation. When handwheel 7 is rotated clockwise the
correction speed decreases, when rotated anticlockwise it increases. Carry out adjustment of
handwheel 7 after you finish adjusting the RLL and mounted implements (plough, tiller etc.).
When preparing implement for work with the use of draft control method proceed as
follows:
- install upper link 2 (figure 2.28.12) of the lift linkage on the upper hole of clevis 1
(position “A” in figure 2.28.12);
- attach the mounted implement (machine) to the tractor RLL;
- if necessary carry out adjustments of RLL and mounted implements.
- switch on draft control method, for doing this raise the mounted implement (ma-
chine) in the upper most position and get switch 4 into the groove of draft lever 5 by turn-
ing switch to the left (along the tractor) into position “II”. For easier switching before getting
into the groove, shift the switch forward (along the tractor) until it is aligned with the groove
on lever 5;
- adjust handwheel of correction speed control 3. When the handwheel is rotated
clockwise the correction speed decreases, when rotated anticlockwise it increases. Turning the
handwheel, achieve smooth automatic adjustment of depth during operation. Do not turn in the
handwheel clockwise against the stop, because it will lead to excessively slow lifting of the im-
plement (machine) and will cause increased slipping of tractor drive wheels.
