PTO shaft to mower stuck on tractor

[copperman1948]

I have a 5410 John Deere tractor with a 10' wide mower. The mower pto shaft has become stuck on the tractor's pto shaft. I have remove the standard release pin completely. I can see all the way through the hole where the pin
holds the mower pto shaft on the tractor and have confirmed the release pin is NOT the problem. Have use two pry bars to try to pry the mower shaft off while pulling on it with a 2000 pound come-along.
Does anyone have any suggestions?

Have you tried heat? Like a torch?

CRC Freeze Off - No turning back once you try it.

Am not aware of CRC. Can you tell me what it is?

newbury,
If you get my responce twice, forgive. I have not tried heat as I did not want to burn out the seal on the tractor, but looks as though I have no choice.

Here's a link and if you google it there are you tube's also.
I agree with not using heat - seal damage for sure.

I think I'd disassemble the u joint and apply a good two jaw puller.

I wonder if you pushed a big bar of steel cross-ways into the U joint and whacked the end down in the opposite direction that the PTO shaft would normally turn would this possibly free up the galling that may have occurred between the PTO stub and the U joint coupler. Just an Idea, and would not take long to try it.

Can you get a chain/hook on the PTO shaft, maybe through the u-joint with something like a bar to spread the load, attach that to something massive, and try using the tractor to pull it free?

most auto parts stores have it, what it does is lowers the temp really fast and is about 6 bucks a can . it is made by crc and is called freeze off.
