Kurt, A couple of more things to try. First,get a couple of pieces of angle iron(1"x1"x1_8"),approx. length of 24". Weld these to the auger in the center 180 degrees from each other.You would be surprised how well this keeps the trash being grabbed and forced under auger.Another item to try is adding some small flat iron pieces(1_8"x1"x1"),stand them on edge of flighting in the center and weld to flighting,spacing them on about every foot.This will also help grab trash that wants build.Keep these items within the throat area to minimize ear shelling. Hope this helps, Hyper Harvest II
