  • Patent number: 5000650
    Abstract: The material loading machine supported on the ground surface is in combination with a return to travel assembly. The combination includes a material loading machine chassis, a work implement, and at least one lift arm supported by the chassis to pivot between an uppermost position and a lower most position while supporting the work implement. Actuators pivotally raise and lower the lift arm. A lift arm position control system automatically stops the lift arm in an uppermost position when it is raised upwardly and automatically stops the lift arm in a return to travel position when it is lowered. In the return to travel position the work implement is located safely above the ground surface so that the vehicle may travel without scraping the work implement on the ground surface.
