Make sure feeder belts are tentioned properly and set on high speed. Be sure no dirt has built up in feeder housing. Check message from a couple days ago on feeder cluches to super fine tune feeding. Be sure corn strippers are removed from bottom of square tube and install W-ring guide rings on tention drum. Good day. Dan
