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.
