As everyone else says.... just add a slip clutch. Apparently, they don't have rocks in China ??? 

If your tiller has a standard six spline @ the tiller end, you can buy a slip clutch that goes on just as your tiller-end PTO shaft does..... then, just slip the PTO shaft onto the slip clutch (after you adjust the length of the PTO shaft).

Do a search here on TBN for the correct process on adjusting your slip clutch once it is installed.
