I looked at the combine again and I think that the heilcals are out of a P3 processor and were forced in there at a shallow angle. The channels don't sit quite flat on the inside of the cage, so I don't think they are running at the angle that they are supposed to. The far right channel ends up being only about eight inches in on the front side above the feeder opening. lookes like it could get pretty constipated in there! Anyway, thanks for the replies!! Darin
