Power regulation of the lifting of the rear three-point hitc
PGPPN044
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.
Mixed regulation of lifting the rear three-point hitch
PGPPN178
Mixed regulation of lifting 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 and at the same time it prevents any
increase in depth of tilling in case of smaller soil resistance.
Set the depth of tilling by lever (1) as described in 'Power regulation of the lifting of the rear three-point hitch'.
Then start moving lever (2) in the direction shown by the arrow until the arms of the rear three-point hitch
start to rise slightly. Herewith, mixed regulation has been set. Move the adjustable stop (5) to lever (2) which
has been set and lock it. 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 the preset
sto
