Position regulation of rear three-point linkage heave
NM13N014
Position regulation of rear three-point linkage heave is a means of regulation with which the tools connected
in three-point linkage is kept automatically at constant height (position) to tractor. Shift lever (1) to front
position (d). Perform vertical adjustment of rear three-point linkage with a lever (2) in (b) range. Height
setting is smooth in the range of 1-9. With number 1, there are three-point linkage arms in lower position,
with number 9 in upmost position. Position (c) is a transport position, in which tools connected in rear three-
point linkage are heaved to maximum.
For transporting tools connected in rear three-point linkage always use position regulation.

control of speed of three-point linkage lowering (3) in the direction of an arrow. If tools hinged in
three-point linkage cannot be lowered in transport position, check the position of the speed of
lowering control (3) - turn it against the direction of an arrow. If tools hinged in rear three-point
linkage are long and heavy, there can be blockage of three-point linkage arms in transport position
during transport. If lowering speed control (3) is permitted and still a tool it cannot be lowered, move
the lever (2) to floating position (c) for a short time and immediately return to the lowering range (b).
The arms of rear three-point linkage start dropping according to a set lever (2).
Power regulation of three-point linkage heave
NM13N015
Power regulation of three-point linkage heave is a means of regulation with which the tools connected in rear
three-point linkage is automatically vertically readjusted depending on the change in soil resistance.
Place lever (2) to (f) position. Shift lever (1) to (g) position, start tractor and by shifting lever (1) from (g)
position in the direction of an arrow, set the depth of oil cultivation (in (g) position, the depth of soil cultivation
is smallest).
As soon as you determine the depth of soil cultivation, the lever (1) must be kept in constant position (1) and
at the end of the row to always heave tool connected in rear three-point linkage by only shifting the lever (2)
to (e) position. By shifting lever (2) to (f) position, you will return tool back to working position.
If there is oscillation of rear three-point linkage due to variable soil resistance, this can be
limited by setting lower sensitivity of hydraulic system by turning the control (4) in the direction of an
arrow
