Adjusting sowing depth

Figure 2.20
The drilling depth of the centre section is set using the stop bolt (A). The drilling depth of the side
sections is adjusted with the cranks (B). The scale indications do not constitute absolute values of
the drilling depth in centimetres but serve as an index only. For considerable adjustments of the
drilling depth, It may be necessary to adjust the horizontal alignment. See "2.7 Horizontal align-
ment" on page 18. Also see "3.1 Sowing depth" on page 64.

Adjusting the wing sections

Figure 2.21
A hydraulic lock is used to lock the extending/retracting ram automatically in the extended posi-
tion, to keep the machine "rigid". This is to ensure even performance across the entire operating
width. For the wing sections to work in line with the mid section, the stop screws (A) may need
to be adjusted. To check these:
Lift up and unfold the drill, see "2.6 Changing between transport position and working position"
on page 16, but keep the machine lifted up on the wheels of the mid section. In this position the
forward frame tubes of the wing sections should be properly aligned (parallel) with the mid sec-
tion.
If the stop bolt (A) needs to be adjusted, first fold up the machine again, see "2.6 Changing be-
tween transport position and working position" on page 16.
