5. Use and adjustment
5.1 Previous soil tillage
5.1.1 Mulching-disc assembly
The working depth of the disc coulters (11.1/1) is
set by the tyre-mounted roller (11.1/2).
Adapt the drill speed to the nature of the mulching
operation. This also increases sowing perfor-
mance.
5.2 Sowing rail
Coulter pressure adjustment: Coulter pressure is
adjusted to a fixed setting. This is based on the
proportional weight of the machine, as transferred
to the coulters and pressure rollers. The paralle-
logram arrangement of coulter elements can be
directed upwards. The disc coulters are spring-
mounted on rubber elements (11.2/2).
5.2.1 Adjustment of sowing depth /
pressure roller
Start by adjusting the pressure rollers (11.4) to the
required sowing depth with the eccentric me-
chanism (16-position) secured in the gauge hole
(11.2/1). - Adjust all pressure rollers to the same
setting.
...for “normal sowing depth”: on a firm, even sur-
face, set the pressure rollers to the coulter level
(11.3/1). (4th or 5th hole 11.5/1). Sowing depth
may have to be corrected for field operation (by
means of the eccentric mechanism and gauge hole
11.2/1)
