Converting a 2-pt hitch tiller to 3-pt?

Actually, you don't really even need a splined end on the pto shaft at the gearbox input. In fact, you may NOT want one. My Japanese tiller doesn't have a slip clutch or a shear pin. You could simply get a u-joint pto shaft end that fits snugly over the gearbox input shaft. If you can't find one the right size, get one for a smaller shaft and have a machine shop turn it on a lathe to get the right diameter. Then drill a cross hole in the gearbox input shaft and the pto shaft for a shear pin. That way you get the tiller working, and provide some mechanical protection for the tiller and tractor.

That sounds like a very good solution to the problem Greg. And, it would be a good means of locking on the tiller end of the drive shaft so that it doesn't slip off when lifting the tiller up and down.

Don't worry so much about the direction of rotation. Tillers will work if they are rotating with or against the direction of travel. I know that the better home owner grade tillers are reverse cut (against the direction of travel). Troy-Built would be one example. I believe the Yanmar tillers are not a reverse cut.

If you need to adapt the pto consider splitting the shaft apart and just replacing the section that doesn't match up.
