After the implement is coupled with the tractor, adjust
length of the upper link.
This is to position the implement to enable it to be at a
proper height above the ground. Retract the upper link to
increase its angle; extend the upper link to decrease the
angle.
The upper lever can be adjusted by turning the guide pipe
weld unit of the upper lever (
①
in the figure):
Turn it clockwise direction to extend the lifting lever;
otherwise, retract it.

4.11.4.Manual adjustment of the limit lever
The limit lever is mainly used to limit lateral oscillation of the implement (i.e. the lower link).
The stop rod length can be adjusted by rotating the threaded
limit sleeve
①
.
Inserting the lock pin into the long hole (B) in the extension
rod ball joint assembly allows the limiting rod to move
somewhat.
Inserting the lock pin into the round hole (A) in the
extension rod ball joint assembly prevents the limiting rod
from moving.
Fig. 4-38
The movement of the limit rod is selected according to working type of the implement. The limit rod should be
moved within a certain range when the tractor with a plough and harrow is working, so that the tractor has excellent
operating performance. The limit lever should be fixed when the tractor with a rotary plough or mower is working.
