Bryan, I agree with Dan,if everything is up to spec. as you have replied.Definitely get rid of two reverse bars.If you are seeing rotor loss,then make sure the reverse bars are over the concave area.(I would rather see you install hi-lo cylinder bar configuration to slow material flow though.)Also,take the concave one step further and remove every other wire all the way to the front.This machine needs all the help it can get in getting rid of threshed grain.Then,make sure that the concave is square side to side and get rid of any wedge front to rear set at factory specs.(Corn and soybeans thresh relatively easy,the only time you may have to pull the rear edge up is for tough green pods with soybeans left inside.Good luck,Hyper Harvest II
