The vehicle brake is an automatic braking function created by the hydraulic drive
power train. The machine brakes automatically when pressure is lifted from the
drive pedal.
The parking brake is provided by the spring‐load plate‐compressor brakes (negative
brakes) submerged in oil and integrated in the front wheel hub motors.
The parking brake is always engaged when the engine is not running. The parking
brake can also be engaged with a separate electric switch.
Rigid suspension to the front and rear body.
The front and rear body rotate with respect to each other.
Standard front tyres: 31 x 11.50 ‐ 15 Tyre pressure 0.9–2.0 bar
Broad grass front tyre: 31 x 13.5 ‐ 15 Tyre pressure 0.9–2.0 bar
Rear tyres: 175/13 Tyre pressure 1.2–2.0 bar
Tyre pressures may vary depending on use.
A general pressure guideline is 1.6–1.8 bar both front and back, unless otherwise
stated on the tool.
