I could make a dualed TW-20 (145hp, weighted) spin & not do a thing to a short pto shaft. They can freeze up good.

If other things fail & the shaft is collapsed as short as it can be, you may need to sacrafice the outer shield, and heat the shaft directly. That will get it free.

Note that a shaft can twist & lock itself up, it may not be rusted tight but just plain wrecked.

What's it on? We've always been able to remove the shaft form the implement and pull it apart useing a tractor and going very slow so nothing pops and flies at you. For us, it always seems to be the silo blower's PTO after they sit around for a while before we buy them.

Generally once it moves, with penetrating oil it will keep on going, should be easy once you get any movement at all.

If that's the case, it may be twisted like the other guy said. It should be able to pull apart if the sheilds are over it.

Is it new to you? could be a reason why they sold the baler...

That would depend somewhat on what type of shaft you have. Most often it's the metric shafts that stick like that. I try to get some good penetrant on the shaft tubes. Spray it down inside from the end too. Then take a good hammer... say 1# +. Tap on the yolk and see if they slide apart. It not, then I would remove the shaft from whatever machine it's on. Chain one end to an solid object, and the other end to a tractor. Put some strain on it. If it doesn't give easily, then keep the strain up, and then go back to tapping on the yolk..... After that, I go to heating the outer tube. I haven't had that fail yet, but I don't have a lot of stuck shafts either, so I wouldn't be an authority on the subject. Good luck.
