Adjusting the wing sections
3.7.1
RD 400-450 F
Figure 3.19
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 ”3.4 Changing between transport position and working position,
RD 400-450 F” on page 30, 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 section.
If the stop bolt (A) needs to be adjusted, first fold up the machine again, see ”3.4 Changing bet-
ween transport position and working position, RD 400-450 F” on page 30.

Adjusting the changeover valve
3.8.1
RD 400 - 450 F
Figure 3.20
The valve is usually pre-set on delivery from the factory. The reverse switch (A) activates/deacti-
vates the control system for lowering of the wing sections. When the drill is lowered in working
mode, one of the double-acting hydraulic take-offs of the tractor is linked to the tool bar only.
When the drill is raised onto its wheels, this same hydraulic take-off is also linked to lowering of
the wing sections. Lever (B) must always be as far forward as possible when the drill is in working
mode or Low-Lift. This can be adjusted by sliding valve (A) backwards or forwards in its moun-
ting (C). Tighten the screws for the valve mounting (C) after adjustment so that the valve does not
slip once its position has been set.
