Hydrostatic drive system

acteristics are the same as when using the
standard drive system. The brake response of
the accelerator pedal can be adapted to suit
the work to be performed by applying the
continuous brake (
higher speeds, a safe full brake application is
possible in conjunction with ABS. It is possi-
ble to shift the transmission gears while driv-
ing, without having to open the clutch. Power
output is limited to approximately 60 kW.
"Drive" mode
In "drive" mode, you can drive with automo-
tive hydrostatic transmission; i.e., the vehicle
speed is proportionate to the speed of the
diesel engine. Only the first six gears are
available and the speed is therefore limited to
approximately 50 km/h.
If you call up "drive" mode while the vehicle is
stationary, the previously selected pulling-
away gear is chosen.
You can choose from two operating modes in
driving mode "drive":
M drive: you must change the gears man-
R
ually. This operating mode is suitable for
front loader use, for example, when you
need to drive forwards and backwards
repeatedly.
A drive: gears are selected automatically.
R
This operating mode is suitable for interval
use, for example, including roadside post
cleaning.

Environmental note
The hydrostatic drive system is particularly
suitable for slow work trips. Avoid using the
hydrostatic drive system at high speeds. This
reduces fuel consumption and therefore
actively contributes to protection of the envi-
ronment.

"Work" mode
In "work" mode you can select the vehicle
speed and the working speed independent of
the speed of the diesel engine. The work
mode is suitable for work with a snow blower,
for example, when you wish to set the vehicle
speed and the working speed separately.
You must change gears manually. Only the
first six gears are available and the speed is
therefore limited to approximately 50 km/h.
