Twisted PTO Shaft

[pennwalk]

Agri supply (agrisupply.com) sells shafts. Looks like good prices. There is a hardware store here that has a pto shaft department. They have all the parts to fix a bent shaft. Any chance there is something like that around you?

I only have a Tractor Suply Co. near by. They have PTO shaft parts, but I'm pretty sure thay don't have a replacement slip clutch to fit the shaft on the brush hog. That's where I'm stuck at the moment.

Thanks!

You say in your signature that it is a 5' Servis-Rhino shredder. I think you would be best served to get in touch with Servis-Rhino for replacement parts. They will no doubt be expensive, but may be less than your alternative. I don't see a simple way to change the input shaft. I think you'll have to change the whole gearbox. I would see about getting the driveshaft fixed and put a slip-clutch on the tractor PTO stub. Just let the cutter's slip-clutch remain frozen. You'll have to shorten the shaft a bit, but you'll have a working clutch and the protection you need.

put a slip-clutch on the tractor PTO stub.

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

What about repairing the old clutch with new discs and then cut out the bent/broken part of the hollow pto tubing. Then extend the pto to the correct length and slide a piece of black pipe over the outside diameter and weld in place? From the pictures the square drive is only at the very end next to the u joint. The best fix would be to go back to Servis-Rhino for parts and get your pto shielding back in place. Ken Sweet

Looking at the picture in post #7.....there are chains attached at the bottom of the bars that go to rear of the deck (3-point top link). I don't recall seeing this on any rotary cutters I have looked at. If the ground terrain promoted it, wouldn't this allow the rear of the cutter to raise well beyond what is normal as it would just freely pivot on the lower lift arms? Could this action be putting the PTO shaft in a condition that it can't handle?

Disclaimer; I don't even own a rotary cutter so an expert I am not.....just making observations and asking questions.

I don't think the PTO shaft is to short, I also think the shaft got hit by the raising of the brush hog.

Go to a machine shop, they can and will cut out the bent tube and replace with a new one ... they may even rebulit the clutch.

No way to know unless you measure the shaft overlap.

No way to know unless you measure the shaft overlap.

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.

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.
