ABSTRACT:
Systems are disclosed for the driving of a truck during a paving operation by an operator located alongside the truck and adjacent the paving site. The truck transmission power take off powers a hydraulic pump with pump output being controlled by a pair of solenoid valves with one regulating fluid flow to a hydraulic drive motor driving the truck differential through a gear reduction drive while the other valve controls fluid flow to a hydraulic motor coupled to a steering component of the truck. Both of the solenoid valves are in electrical circuit with switches located exteriorally on the truck for access by the dismounted driver as is a truck brake control. Accordingly steering, braking and fore and aft truck movement may all be accomplished by an operator positioned adjacent the truck.
