Abstract
An apparatus is disclosed for controlling the propulsion and steering of a machine. The machine includes a hydrostatic system that drives a pair of ground engaging traction devices. An electronic controller receives operator signals indicative of a desired travel speed and direction, and determines a desired rotational speed of the ground engaging traction devices. The electronic controller produces command signals indicative of the determined speeds to regulate the speed of the ground engaging traction devices to the desired speed.
