Differential Steering System. A planetarydifferential turns the machine by speedingup one track and slowing the other,while maintaining full power to both.The system consists of three planetarygear sets.

Provides enhanced side slopecapability.

Two planetary gear sets(steering and drive) make upthe dual differential, whichperforms the traditional drivefunction (forward or reverse).Unlike competitive machines,the differential also performs asteering function with input fromthe steering motor.

A third planetary gear set, theequalizing planetary, residesinside the transmission case. It isconnected to the dual differential,which provides a maximum speeddifference between the right and leftfinal drives during a turn.

A dedicated variable-displacementhydraulic pump.

A bi-directional, fixed-displacementsteering motor.

Heavy-duty steering drive gears.

Planetary Power Shift Transmission.Three speeds forward and three speedsreverse, utilizing large diameter, highcapacity, oil-cooled clutches.

Modulation system permits fastspeed and direction changes.
