I've got a '21 4707 and really like it. I have one gripe, however: the 3pt hitch sliding button/lever control doesn't 100% control the arms. You move the sliding button to raise the arms and even after you stop, the arms keep going a little bit. Same when going down. Makes it a little frustrating when you don't have 100% control over it. Other than that, it's a great tractor and easily the most comfortable to operate that I've ever experienced. The Radial tires, rubber mounted cab, rubber floor mat, and air ride seat make it soooo nice.
