ALL WHEEL DRIVE
Selectable in addition to the hydrodynamic rear-wheel drive.
Hydrostatic front-wheel drive with E.D.C.V. ( Electronic Drive Control Volume ).
A bi-directional swash plate pump (forward/ reverse) drives wheel-hub mounted motors in each of the front wheels.
Hydraulic No-Spin differential prevents one-sided wheel spin and proportions torque when cornering.
A microprocessor monitors and matches front- and rear-wheel drive forces.
A stepless switch allows the operator to adapt front-wheel thrust to existing job conditions.
Creep mode as standard: front traction only, for ultra low machine speed.
BRAKES
Hydraulic, dual-circuit accumulator pump braking with 4 oil bath disc brakes acting on tandem-wheels. Parking brake: disc brake acting on transmission.
