sensitivity of the hydraulics in power or mixed regulation.
Turning the knob in (a) direction increases sensitivity,
turning it in (b) direction decreases sensitivity.
PGPPN037
Position regulation of the lifting of the rear three-point hitch
PGPPN043
Position regulation of the lifting of the rear three-point hitch means that the tool connected to the rear three-
point hitch is automatically kept in the same height (position) with regard to the tractor.
Move lever (1) to the front position (d). Adjust the height of the rear three-point hitch with tools within the (b)
range by lever (2). Adjusting the height is smooth within the range 1 - 9. In position 1, the arms of the rear
three-point hitch are in the lower position, in position 9, in the highest position. Position (c) is a transport
position when the tools connected to the rear three-point hitch is raised at maximum.
To transport tools which are connected to the rear three-point hitch always use position
regulation.
To raise tools into transport position, turn the three-point hitch lowering speed control knob (3) in
the direction shown by the arrow up to the stop point, which results in interrupting the oil flow in
hydraulics. Should tools connected to the rear three-point hitch not be lowered, check the position of
the speed lowering control knob (3) - turn it in the opposite direction than shown by the arrow.
If tools connected to the rear three-point hitch are long and heavy, the arms of the rear three-point
hitch may get locked in the transport position during transport. If the lowering speed control knob (3)
is loosened and the tools still cannot be lowered, move lever (2) to the floating position (c) for a short
time and immediately get back to the lowering range (b). The arms of the rear three-point hitch start
to go down as set by lever (2).
