Well how crazy am I wanting to try this? Making it attach to a Cat 0 or Cat 1 3point should not be very much trouble. Converting the 540 PTO to run the tiller at the correct RPM and how to mount the PTO shaft is the trouble. I saw one person selling with the PTO shaft mounted Direct to the gear box (ariens, very similar tiller style), no belts.... Should I would I need a belt or a slip clutch? Any thoughts on the RPM's ?
