Abstract: A dumping apparatus for combines for collecting threshed material thereon and being adapted to automatically dump the threshed material therefrom when a predetermined weight is accumulated thereon. The apparatus comprises a bottom wall member which is pivotally mounted on the combine below the thresheld material discharge opening. The bottom wall member has a pair of upstanding wall members at its opposite sides and has a plurality of spaced apart tine members secured thereto and extending rearwardly therefrom. The forward end of the bottom wall member has a narrower width than the rearward end thereof to aid the threshed material in moving therefrom when the bottom wall member moves from its normally disposed horizontal position to its dumping position. The means for mounting the bottom wall member on the combine is rearwardly and forwardly adjustable relative to the bottom wall member so that the size of the loads or piles may be selectively varied.
