In response to your question JWK, I really like the GREEN header. It seems like it has more flex and slides better in wetter ground. Also they have a nice big orange ball on the side to view cutting height, as opposed to IH little gauge on the side. looks like this header is put together a lot better. You can adjust the tip of the knife on the header as well as moving the feederhouse on the combine. Doing a beautiful job clipping, running about 4.3 to 4.6mph in 45-50 bushel beans.
