cylinders, four-stroke, turbocharged Diesel engine with
direct injection and a charge air cooler.
Electrical system
The machine has the following control units (ECU,
Electronic Control Unit) and electronic units.
•ECU (for the machine)

Propulsion system/Transmission
The propulsion system is a hydrostatic system with a
hydraulic pump supplying two motors connected in
parallel, one for the rear axle and one for the drum.
The speed of the machine is proportional to the angle of
the control lever (the deflection of the forward/reverse
lever regulates the speed). A speed selector and anti-spin
system are available as options.
Brake system
The brake system comprises a service brake, secondary
brake and parking brake. The service brake system
produces retardation of the propulsion system, i.e.
hydrostatic braking.
Secondary/Parking brake
The secondary and parking brake system comprises
sprung disc brakes on the rear axle and the drum gear
which are disengaged by hydraulic pressure.
