I have a 9670 deere and yesterday I cut 70 acres of the greenest beans I've ever cut in my life.  These beans not only had green stems but also many many grass green leaves, you would have thought I WAS NUTS.  Any way they tested 12 percent but were still a litttle damp from running all the crap through with them.  I used to own a 1666 and I know there is a bunch of differences buy there is no way it could have done what I did yesterday.
