Front drum needs to down all the way and allowed to float with the rocktrap. Make sure you have the slower speed sprocket on the rocktrap drive (30 tooth) (20 tooth is high speed). Rock trap blades fully retracted for grains or even removed completely works better yet. Don't forget to re-install them before beans though. Forget the finger grate for the rocktrap sump doesn't help much.
Make sure your bottom auger stops are clean on the LH and RH side of the head before you make any adjustments to the auger height. They fill up with foreign material and will prevent the auger from lowering all the way on the stops. Raise the reel all the way and see if your auger raises up or not then check both sides with the auger raised all the way and clean them out. (1020/1010 header)
Higher the auger is away from the head floor the poorer the performance of the header. Adjust as close to the floor without auger hitting the floor.
Check the back stripper on the head, make sure it is adjusted for your feeder opening and not for an 80/88 series feeder opening.
