Looking for some answers on a 6600. Started shelling corn today, been a very late and wet fall in the finger lakes and moisture today was 28%, and underneath my feet in the feederhouse and as soon as corn would start entering would come a loud banging noise that was not consistent time wise. In other words it would bang at random but pretty often. I realized that I did not adjust the drum with the little setup at the bottom of the feeder house and was gonna do that first thing tomorrow morning. But am,also curious if there might be more to the issue than that. If anyone has any ideas I would appreciate hearing them. What puzzles me a little is its only when corn is going through. Harvested 100 acres if do ya with it recently and it never banged or made any noise.
