Update:
Thanx for all the suggestions. SUCCESS finally!!!
I did chain the machine frame, (a PZ 2000 haymaker belt rake), to the bucket of my tractor. Then I put a chain to the ball hitch of my pickup. In between I first used a 1/4 ton come along with a 1" sling through the pto yoke. Didn't want too much torque against the yokes. Twice I tried heating the shaft after soaking it with penetrating oil. Beat on it with 16 oz. ball pean hammers, as well as a 4lb. I also tried using an air chisel. I tried using a wedge between the inside and outside shafts. Took the nylon sling out of the equation, , beat on it some more, using a 3/4 ton wire come along. Beat on it some more, using the tension of the come along. Noticed it had moved about 1/2". Kept at it, beating and cranking. It fought me all the way out.
But it's apart. Now to clean the shafts. Wish I had the bead blaster I used at work.
