ABSTRACT:
Two rotary air valves are mounted on the bucket control levers of an end loader and are operable to control the shifting of the loader's transmission. One of the air valves is used to operate a cylinder connected to the forward and reverse shift valves of the end loader power shift transmission while the other rotary air valve operates a pneumatic cylinder connected to the range selector valves of the power shift transmission. In this manner, both the bucket control functions as well as the forward and reverse movement of the end loader may be totally controlled by one hand of the operator leaving the other hand free to remain on the steering wheel at all times.
