Working depth adjustment.
When attaching the upper fastener to the longitudinal
holes, it is necessary to set the furrow depth by means
of
the
tractor’s
hydraulic
adjustment
(force/positional)
Setting the working depth of the plough on the gauge
wheel is done using the screw crank. The setting is the
same on the left and right sides. Bumpers (screws with
a lock nut) allow the angle of the gauge wheel arm to
be changed relative to the ground. It enables to
change the distribution of forces acting on the wheel
moving in a hash terrain. A change of the wheel arm
angle leads also to the change of the working depth.
