ABSTRACT:
A control system for positioning an implement used on a tractor. A control system selects the direction and speed of a hydrostatically powered tractor. A first switch allows the implement to be raised or lowered and is located on the control lever. A second switch allows the operating position of the implement to be present in an automatic mode and a third switch allows either the automatic or manual mode to be selected. The control lever is movable from its neutral position forwardly or rearwardly by operating a release mechanism.
