I've used a Craftsman "counterrotating" walk behind tiller and it worked great; never actually used one on the tractor, although I've seen Kubota's on a
B7100. This topic has been discussed before on the forum and I think it boils down basically to:
1) the counterrotating (or reverse rotating, if you prefer) tillers do an excellent job; a little bit better than a forward rotating tiller,
2) the forward rotating will do as good if you either go slow enough, or make a seond pass,
3) the counterrotating tiller costs a
lot more than the forward rotating ones (why I don't know), and,
4) if you happen upon a big rock, root, or other immovable object, the forward rotating tiller will hop over it, while the counterrotating one may catch at time below and behind it while the tractor is moving forward, increasing the liklihood of breaking a tine, or shearing a pin (if that's what you have instead of a slip clutch).
