ABSTRACT:
A method is provided for controlling steering in a hydrostatic drive system having a differential steer mechanism that uses flow from the hydrostatic drive system to drive the differential steer motor. The method utilizes independently controlled brakes on the respective right and left drive units to assist the differential steer mechanism in the event the pressurized fluid from the hydrostatic drive system is reduced during the operation of the machine.
