pacerron,
this is a draw bar pulled mower that uses hydraulic lift to raise and lower. both tractor and mower are John Deere and the PTO shaft had a ring around it that would turn approximately 1/3 turn to release the PTO. when turing this ring it push down on a pin that released the pto shaft, after replacing the turn ring twice I just left it off and depressed the pin, that the ring had depressed when turned, with my thumb to release the pto. When I could not get the pto off by depressing the pin, I though the pin was the problem and took it out. Turns out the pin was not the problem. So in sumation, my pto shaft should slide right off, but will not budge.
Thanks for the clarification.
You must have a bur someplace. It sounds like you rarely take it off if you leave it hang.
Have you tried putting a couple blocks under the shaft to get it close to level and taking downward pull off it?
Since you have all the locking pins removed will it slide forward any?
On Ford and New Holland tractors we have a recess milled in the PTO shaft for the lock pin which is part of the shaft coupling.
Most are just spring loaded pins but some are a rotational wheel similar to what you describe to be part of your tractor.
On our shafts you can slide the coupling a little beyond the pin point if you hold the pin down against the spring pressure.
I would be leary of beating on or heating back there. You might get lucky but pay a big price down the road.
The vibration I suggested was from something like a little air chisel with a piece of soft rod stuck in the end or a pin punch
piece made for the chisel. It is not the hard force but the vibration that does the job.
You can beat on pressed in bushings and bearing races all day long with a punch and 3 pound sledge without budging them,
but a few burps from a vibrating chisel usually walks them right out.
Anyway, good luck.
I better defer to the John Deere guys on this one.
