P.S. Running cleaning fan full speed. Also, despite problem, don't seem to be throwing over any beans out the back.

Bolted to the rear crossbar of the concave should be a small angle iron shaped piece. If this wears badly enough to break, the cylinder action will roll the round suspension rods out of the concave, allowing large material to escape thru the concave. Also, bolted to the front of the concave is a feedplate. If this is worn badly or missing, large material can escape before entering the threshing area. In either case, large components will pile up on the grain pan dividers and the piling will remain fairly constant.

I'm pretty sure I found the problem today when I crawled deep into the bowels of the combine with a flashlight. The grain pan was all covered with what I'm guessing is coon poop. Enough there to cover the ripples and some good sized clumps near the back. Sure looked like it would impede flow. Cleaned it off as best as I could, but then it rained, so will have to wait til tommorrow to find out if that was the problem. Thanks for the other responses! g.s.
