I fell over from the NH board so don't hate on me too much. Trying to help a neighbor out. He has a 6620 and the other day I helped him do some small repairs. I looked over the machine as I was curious how they are setup since I am used to NH rotaries. Anyways, I saw his concave and am concerned with the number of wires in it. Before going to round bar concaves we ran with most of the wires out of the concaves to allow grain to pass and still got a clean sample and now with the round bars it is even better. I told him he may be able to take out some wires and I would check to see if that is a good idea on the Deere or not. So how do ya'll who run the similar machines have your concaves setup when using them in corn and soybeans? Thanks!
