Tiller PTO shaft separates when lifted.

Thanks, The overlap in the shaft has to be increased. An extender will not work because I would not be able to lower the tiller with out it binding.

The only way is to move the tiller back and use the increase length where the shaft overlaps. This will solve the problem.

I was considering removing the slip clutch which would give me about 4 inches more but its probably much better to move the tiller back about 10 inches minimum and use the slip clutch.
That would be enough.

Tractor Supply sells a PTO extender, but I think it only extends it by 3" or so. Sounds like you need a lot more than a 3 inch extension, so a new shaft half is probably in order.
