I was doing some brush hogging today. All of a sudden I got a bad vibration from the back end. I turned around to see my PTO shaft twisted and about to come apart. I didn't think I was working in very heavy stuff. I don't think the slip clutch is working too good.... Time to go shopping

First of all, I'd like to thank you all for your input here. It has been helpfull in giving me a path forward.
I have contacted Rhino to see what their advice will be. We'll see what they say.
I have tried to seperate the inner PTO shaft from the tube and as of right now, it's stuck on there pretty good. I didn't try too hard because my first thought was to trash it and just get a whole new set-up. I'll give it another go soon and see if it will come apart. I'm thinking the twist has the end of the inner shaft enough to bind it in there.
If Rhino doen't have a good solution, I'm looking at two other options:
One, try again to get the slip clutch apart and rebuilt and just put a new PTO shaft on there.
Two, cut the end of the gear box shaft off and drill a hole to make it a shear pin set-up.
What are the thoughts on option two??
Thansk again guys! You've all been a big help.

Dangerous suggestion. Especially if the slip clutch is sizeable enough that the PTO shroud has to be removed. Damned dangerous suggestion.

Dead simple, but I guess you've missed the other hundred or so times this has been hashed out here. Look at the product in the link you're provided; diameter 6". And I can tell you as a PTO clutch devotee, that thing will stick out another 6" from your tractor's PTO stub. Not many PTO shrouds extend that far. Even if it happens to fit under the PTO shroud, there are possibly still eight spinning spring/bolts exposed. And if the shroud actually has to be removed - just to fit the slip clutch - then you're talking fully exposed death/dismemberment potential.Greg, you've stated your position, but not given any reason why this would be dangerous. Please expand your comment with your reasoning.
The twist was about half way up the female shaft which means the male shaft was about half way inside. That is not too short.

That said, NEVER put a friction clutch directly on the tractor's PTO output shaft, your insurance company may consider it suicidal.

The operative word in my advice was "friction". What you just listed are not friction clutches. Being 1/3 or less the diameter of a friction clutch - and not having any dangerously exposed spring bolts - those on your list are no where near as dangerous. I've got nothing against those items, just keep the big friction slip clutches off the PTO stub.Tractor Supply sells PTO stub slip clutches, overrun clutches, and PTO stub extensions, and they are on their shelves with no OSHA warnings.
