The other day I was bushhogging and a strap of some kind got thrown around the pto bushhog coupling head. It apparently messed up the plastic or something as I can't get the shaft unhooked from the tractor. I can pull the coupler ring back, but it will not slip off the shaft. Any suggestions? Thanks!

Maybe the PTO shaft got pinched or bent so it resists telescoping? Try raising and lowering the 3pt hitch to see if that loosens it.

So is the pin on the PTO coupling depressing like it should?
It sounds like his is the collar type shaft.
I've had similar problems before on a disc mower. In my case the collar wasn't actually coming all the way back. I whacked it one good time with a hitch pin and it came right off. I sprayed Liquid Wrench or something like that on it afterwards and have had no problems since.
I don't have a pin, I have a slip collar. The collar is moving back like it should, but I can't get the coupler to move off the shaft. The only thing that appears to be damaged is the plastic parts around the ring of the collar. I don't know if there is some residual strap stopping the movement or what.

Boy, ain't that the truth. I would cut the plastic back some, then try again.

Sorry the original post did reference the slip collar if I had read better.......
It's really difficult to get a hammer in to tap the collar back so cutting the plastic is the first option. A pull hammer with a bearing puller might be adapted to pull the collar back. The slip collar is held on the PTO shaft by ball bearings that are held in in the grooce on the pto shaft by the spring pressure on the sliding collar. A split ring holds the slip collar on the PTO shaft. It too may be difficult to get to while on the back of the tractor. If you can't pry the collar back, it maybe necessary to cut the collar. They aren't hard to replace and most farm supply equipment places have them. But like any repair parts, they aren't cheap.

I would almost bet that you need to push forward on the collar rather than back. Mine on my bush hog brand it that way. It will move to the rear just like the front with center being locked and pulling back doesn't release it. Last time I put mine on it stayed on for months and when I was trying to remove it, I just couldn't get it to budge and I was pulling it to the rear. Somehow I pushed on it and it slide forward so I then knew that the collar had to be pushed forward not pulled back. If you have the twist to release, then I have had the ball bearings rust up and not fall back inside. Lots of penetrant and a few taps with a hammer finally released the retainers.

Personally, I detest those slip collars. The seem to always be hard no matter what.
If (WHEN:thumbsup
you get the collar off of the shaft you may consider switching it out for a pin type. Tractor Supply and tractor dealers have them.
Just tap out the U-joint and replace the end.

Okay, I decided to approach this trying the simplest method first and it worked. I simply used a small crow bar to apply leverage on the collar while holding the collar back so it could slide off the shaft. With just minimal coaxing she came right off. One lesson learned here for sure, I will go get me the pin type to replace the slip on collar. Those things are the work of the devil. LOL!!!
Thanks for all the suggestions!

Glad it worked for you. I agree, the pin type is simpler when they malfunction.

Glad your problem is solved. Use a lot of grease on the splines and other sliding parts. I make it a rule never to keep pto driven equipment attached to the tractor unless I plan to use the implement within the next few days. Eliminates a lot of problems with stuck pto splines etc.
