Some clarification please

should I be running an "over running" PTO clutch adapter on my rear PTO on my BX-25 for tilling
or does it have an internal one, or does it need it at all?

thanks in advance

With little or no centrifugal force developed using a roto tiller, you should not need a overrun clutch. Slip clutch is very nice option to have on a tiller. Ken Sweet

It's not like you going to try starting the tiller in/on the ground first. Start it up before lowering it and then slowly drop 3 pt and go to work. I have a slip clutch on mine due to rocks or tree roots/wild grape vines that was on my virgin ground . I dont need it anymore now but its a peace of mind to know slip clutch is there to save my BX pto.

I used an external overrunning clutch on PTO's linked to travel speed, such as our old 8N Ford. A bush hog can drive the tractor forward without an overrunning clutch in such a case. Your BX is completely independent of ground speed, so I don't think it would be a problem.

Some PTO's do have internal breaking to stop the PTO shaft when disengaged, and that break cannot stop a great deal of inertia effectively, so I always try to disengage in a fully throttled down state.
