Almos tall the grey market Japanese tillers are CW rotation. I understand there are a few out there for CCW for use on some smaller and older models of (I think) Mitsubishi tractors, but are pretty rare. The main thing to take into consideration on many of the 2-PT tillers (like mine) is that they generally have a 16 or 18 spline metric type PTO shaft (about 30mm) and you have to adapt a std. 1-3/8" 6-spline PTO shaft to it. I used a 1-3/8"M 6-spline X 1"F PTO adapter and had it reamed out to fit the 30mm tiller shaft, and simply welded it to the shaft. Now it's a permanent std 1-3/8" tiller. But you can eliminate all of those adapter problems by just getting a 3-pt grey market tiller, much less hassle. As for where to buy, I found mine on e-Bay and it was located in OK at some equipment company there, can't remember the name.
