ABSTRACT:
In a single lever control for the feeder conveyors of a combine harvester, movement of a manually operated lever directly actuates a drive train for driving the conveyors in a forward or normal operating direction. A second lever controls actuation of a drive train for driving the feeder conveyors in a reverse direction. Movement of the second lever is responsive only to movement of the first through a cam slot and cam follower arranged so that selection of the drive for one direction automatically disengages the drive for the opposite direction. A detent gate at the neutral position forces the operator to pause when passing through the neutral position, that is when disengaging one drive and engaging the other.
