Automatic Tyre Pressure
Control (ATP) (optional)
The tyre pressure control system detects
whether the machine is driving on the field or on
the road or the filling level in the spraying mixture
container. The tyre pressure and thus the tyre
ground contact area is automatically adjusted
to the respective requirement.
Road travel is done with high tyre pressure. The
tyre ground contact area is small. This ensures
good driving stability and low tyre wear.
At the field, the tyre pressure is lowered
automatically and quickly. The tyre ground
contact area is larger. This reduces the ground
pressure.
Tyre ground contact area depends on the tyre pressure
The settings on the tyre pressure control system
are made on the machine terminal. Refer to the
pertaining terminal operating instructions.
NOTE
The maximum settings on the compressed air
controller of the control valve must not be ch-
anged. Danger of tyre exploding! Settings may
only be made by the HORSCH service.
Maintenance
Two additional air reservoirs are installed for the
tyre pressure control system. The air reservoirs
are located in the front-end under the claddings.
Open the cover flap on the right side for this
purpose.
Air reservoir
The air reservoirs must be drained daily before
starting work by operating the valve.
¾
Pull the drain valve until water stops running
out from the air reservoir through the valve.
¾
In case of contamination unscrew the drain
valve from the air vessel and clean the air
vessel.
A control valve is located on the underside of
the machine to which a service unit is attached.
Drain the filter-regulator combination no later
than every 100 operating hours or as needed
by turning the grey drain plug.
