5.13.1 Hydraulic pumps
• The drive pump drives the 4 parallel switched wheel motors in a
closed circuit.
• The feed pump supplies the system with leakage oil and flushing
oil.
• The pump for the drive of the spraying pumps and the fan mo-
tors is a regulating pump load sensing controller. The operating
pressure of the pump is adjusted automatically depending on t
output required.
• The regulating pump with constant pressure controller supplies
the steering system and hydraulic cylinder with oil.
Adjusting and checking the system is carried out in the factory. Nor-
mally, the settings do not need to be corrected.
The operator requires special tools and special knowledge of the
system in order to adjust the highest pressure, the operating pressure
and the speed. This is why the adjustment work may only be carried
out in the factory.
5.13.2 Hydraulic wheel motors and gearbox
• The 4 motors and the driving pump must all be precisely adjust-
ed to each other.
• Have all repair work or adjustments carried out by a specialist
workshop.
