Chris,
     It isn't too late, we can cure you ! You can still trade those "other " green tractors in for the true green machines!     Just kidding, don't let on, but I have a few other tractors that aren't quite green also.
   If you are looking for Oliver 60 parts, there are quite a few places to go for parts,
