RoGator 418
Hydrostatic Drive
CAUTION
!
The drive system of the RoGator
is hydrostatic. After carefully
reading and having understood
the manual, practice driving with
the RoGator in a safe area be-
fore driving with the RoGator in
the field or on the road.
Accidents or damage can result
if you are not used to driving
with a hydrostatic drive and re-
spond improperly to certain
situations.
Traction Control Lever, Pump and
Wheel Motors.
Pushing the traction control lever forward or back
modulates the swash plate in the pumps, allowing
hydraulic oil under pressure to flow to the four wheel
motors in a closed system. The traction control lever
is connected to the pumps, which control the speed
of the vehicle by regulating the amount of oil flowing
to the wheel motors. The RoGator has two possible
travel mode switch positions:
1. Field position
2. Road position.
When driving with the travel mode switch in the field
position, the vehicle speed is not controlled with the
engine speed but with the position of the traction
control lever. In this situation the hand throttle must
be used.
In the road position this lever is moved forward or
back as far as possible. The speed of the machine
is determined by the accelerator pedal.
Engine
The Diesel engine drives the pumps.
Low-pressure Pump
The low-pressure pump (a part of the traction
pump) generates a low pressure for:
1. Flushing the system,
2. Modulating the traction pump.
Combined Cooler
The oil part of the combined cooler cools the flush-
ing and leakage oil before it flows back to the hy-
draulic oil tank.
Tank and Filter
The complete return oil flows through the suction
and return oil filter. A part of the filtered oil flows to
the intake line of the low-pressure pumps and the
rest goes to the hydraulic tank.
