Rubber mounting
NOTE
¾
Keep the rubber mounting free of oil.
Oils and grease can harm the rubber and thus
adversely affect the function.
Harrow
The height and angle of attack of the harrow can
be adjusted, if necessary.
1
¾
Adjust the height: Unscrew the screw (1) and
tighten the bracket again in the next position.
2
¾
Increase the angle of attack (aggressiveness):
Slightly lift the seed bar and screw down the
screw (2) in the upper position behind the
harrow.
¾
Adjust all harrows equally.
Maintenance
¾
Check press rollers for condition, light move-
ment and tight fit.
¾
Readjust the scraper on the press rollers if
required.
¾
Check the scrapers and uniformers for con-
dition, tight fit and adjustment.
¾
Check coulter discs and bearings for wear,
light movement and preload.
¾
Tighten the screws for the coulter disc bear-
ings (M 16 x 1.5) with 130 - 150 Nm.
Tighten the screws for the coulter discs
(6 x M 8 each) with 38 Nm.
Check the rubber mounting and replace if aged
or showing reduced tensioning force.
Depth setting
The drilling depth is determined by the depth
setting on the hydraulic cylinders 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.
