Assuming you have a 2208 corn headIJ 1) Ensure feeder chain is as far forward as possible, and roll face plate back to flatten out head. 2)There is a feeding enhancement kit that creates a small pocket behind the auger this may also help 3)Open deck plates as wide as possible without creating header loss, this will eliminate some trash intake. 4)Time gathering chains point to point-Changes relationship between snapping rolls and chain timing 5) Move header auger up and forward just like food grade_popcorn headers are setup-this will leave alot in the auger trough but just lower it down when done and clean out. These things have all helped me in some way. Good luck
