ABSTRACT:
A skid-steered tractor vehicle is driven by right and left hydrostatic transmissions having separate steering levers, one for each transmission. A centering device acting directly on the transmission controls is longitudinally shiftable against the force of a spring in response to pivotal movement of either steering lever from a neutral or idle position for returning the steering lever upon release. Also, there is a second pivotal mounting for one or both steering levers in a plane at right angles to the pivot axis of the levers for controlling auxiliary functions without interfering with the steering movements of the levers.
