Machine description
Diesel engine
The machine is equipped with a water-cooled, straight
four cylinder, four-stroke, turbocharged diesel engine
with direct injection and a charge air cooler.
(Stage V)
The engine is also equipped with a Cummins ® diesel
oxidation catalyst, a diesel particulate filter and a
selective catalytic reduction (DOC/DPF and SCR)
system for exhaust gas aftertreatment.
Electrical system
The machine has the following control units (ECU,
Electronic Control Unit) and electronic units.
• Main ECU (for the machine)
• Diesel engine control unit (ECM)
• I/O board (Control board)
• Display
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.
Steering system
The steering system is a load-sensing hydrostatic
system. The control valve on the steering column
distributes the flow to the steering cylinders at the
articulated joint. The steering angle is proportional to
the amount the steering wheel is turned.
On certain markets, the machine is also equipped with
