Abstract: A hydraulic propulsion system utilized to propel and steer the front wheel of a harvesting vehicle under the control of a driver. The hydraulic system includes a manually operable forward-reverse-speed control mechanism, for selectively controlling a hydraulic motor which is operatively connected with the front wheel, as well as a foot-pedal operated steering mechanism whereby the driver can effectively control the propulsion of the vehicle and, at the same time, assist with the harvesting operation.
