POSITION REGULATION OF THE LIFTING OF THE REAR THREE-POINT HITCH
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 (d). The
arms of the rear three-point hitch start to go down as set by lever (2).
