ABSTRACT:
A steering system for steering a machine having opposing first and second sides with first and second pairs of rotatably mounted rear wheels disposed along the respective sides and at least one rotatably mounted, spaced front wheel. The system includes at least one first drive unit and at least one second drive unit for rotating the rear wheels of the respective pairs, and a steering input device that provides a signal to a controller that produces drive unit request signals to control the drive units to rotate the associated rear wheels along one side at rotational speeds greater than those along the other side to facilitate turning.
