Adjusting the changeover valve

Figure 3.21

The valve is normally pre-adjusted on delivery from the factory. The changeover valve (A) alter-
nates control between folding of the wing sections and operation of the tool bar. When the drill is
lowered in working mode, one of the double acting hydraulic takeoff points of the tractor is con-
nected to the tool bar and when the drill is raised onto its wheels, this same double acting takeoff
is now connected to the wing folding system.

Lever (B) must always be in the end position when the drill is in transport or working mode. This
can be adjusted by sliding valve A forwards or backwards in its mounting (C). After adjustment,
tighten the bolts on the valve housing (C) so that the valve does not slide on its grooves.
