JD two cylinders are pretty common around here. I had to buy one just to try to fit in (I have a 420 that I'm going to get spiffed up someday). I always wanted an R. Makes the ground shake.
I did an addition to a RDO facility near the California border and was there for four months. There are plenty of people out there fixing them up. A few in a small community near where I grew up still have them as yard ornaments.
