POWER REGULATION OF THE LIFTING OF THE REAR THREE-POINT HITCH
Power regulation of the lifting of the rear three-point hitch means that the tool connected to the rear three-point hitch is
automatically being adjusted depending on changing soil resistance.
Set the adjustable stop (5) to a position on the edge between floating position and the beginning of the range of lifting of the rear
three-point hitch.
Move lever (2) to (f) position – to the adjustable stop (5).
Move lever (1) to (g) position, accelerate the tractor and move lever (1) in the direction shown by the arrow to set the depth of
tilling (in (g) position, depth is the lowest).
Once the depth of tilling is set, lever (1) must be kept in constant position. At the end of each row, raise the tool connected to the
rear three-point hitch only by moving lever (2) to (e) position. To lower the tool to its operating position again, move lever (2) to (f)
position.
The rear three-point hitch may start oscillating under the influence of changing soil resistance. To reduce oscillation, set
lower hydraulic system sensitivity by turning the control knob (4) in (b) direction.
