ABSTRACT:
A self-propelled combine has an elevated grain tank with a laterally extending auger in the bottom of the tank for moving grain to an auger type discharge conveyor mounted on the side of the grain tank and swingable between a fore-and-aft transport position and alternate unloading positions wherein it extends outwardly and upwardly from the end of the grain tank auger. The discharge conveyor and grain tank auger are driven by a drive system that includes a clutch selectively actuated by the operator via a control lever at the operator's station and a drive shaft mounted on and connected to the discharge conveyor and connected to the grain tank auger through a pair of universal joints at the axis of articulation of the discharge conveyor. An interlock device is provided between the control lever and the discharge conveyor, so that the clutch can be engaged to drive the discharge conveyor only when the discharge conveyor is in its extended or unloading position.
