Depth setting
The drilling depth is determined by the depth
setting and the coulter pressure on the coulters.
NOTE
¾
The settings of drilling depth and coulter
pressure affect each other. Check the coulter
pressure in the field after each change of the
placement depth.
¾
Match the adjustment to the soil conditions. It
can only be determined in the field in working
position.
¾
With each change, the drilling depth and the
effect of the press rollers on consolidation and
depth guidance must be checked.
¾
Check the drilling depth when starting work
and regularly during use.
Setting the drilling depth
The drilling depth is adjusted mechanically via
two hexagon shafts and fixed with bolts.

¾
Secure the tractor against rolling away, secure
the control units and switch off the PTO-shaft.
¾
Lower the seed bar until it rests on the ground.
If necessary, vary the height of the seed bar
slightly to facilitate adjustment.
¾
Position the ring spanner (size 19) on the
hexagon shaft (1).
¾
Remove the bolts (2) on both ends of the
shaft.
¾
Adjust the drilling depth by turning the hexa-
gon shaft.
Turn the shaft so that the bolts can be in-
serted.
¾
Insert the bolts (2) and secure each of them
with a cotter pin.
¾
Adjust both segments of the seed bar to the
same height (position of the bolts):
Coulter pressure
The harder the soil and the deeper the seed is
to be placed, the higher the required pressure.
If the coulter pressure is too high, the frame is
lifted up slightly via the press rollers or the press
rollers sink into the soil. Exact depth guidance
is therefore no longer ensured.
The coulter pressure can be increased by back-
ing out the screw adjustment.
¾
For adjustment loosen the handle, fold it into
the guide and secure it with a cotter pin.
¾
Pay attention to the engraved adjusting scale.
¾
Set all screw adjustment uniformly.
