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.
