Nelsoncat, We converted the head to the JD sidehill style drive. We did nothing to the combine, but put on an adapter plate. I have a relative that has a JD sidehill combine and now we can help one another out if one of us gets in a pinch. We also run a JD 212 pickup. Don't raise any beans so we haven't looked at any flexheads. I'm located near a small town called Cadott. It is about 10-12 miles east of Chippewa Falls
