ABSTRACT:
A combine harvester in the area of the grain pan and cleaning sieve which generally reciprocate longitudinally is modified by the provision of a pivot bar beneath the discharge end of the pan and carrying fingers projecting over the sieve. The pivot bar reciprocates with the sieve and is coupled to a lever the other end of which is attached to a second lever fixed to a stationary frame member. Thus the reciprocation of the bar in the direction of the sieve acts to pivotally rotate the fingers about the bar to lift the mat of grain and chaff deposited from the pan away from the sieve.
