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.

Abstract: A control means with a spring lever for use in setting a set of gears in two different positions. The lever is of a spring material which is resilient and capable of being sprung into a position for storing energy whereby the lever will urge the gears into one position, or the lever will hold the gears in one position, to the extent of the spring force available in the lever. A plate member engages the handle of the lever and has two positions for holding the lever in either of the two positions, and the plate is adjustably mounted.
