The equipment groups all seem to have died or I wouldn't post this here.
Anybody run into this before?
The drive line to my mower is stuck on the tractor's pto output shaft
and won't come off. It's been tough to wiggle free before, but never
this bad. I've hammered on it and pried until I fear for the u-joints.
It's soaked with wd-40. The spring pin works easy, but the splines
seem welded with grit. Any ideas would be greatly appreciated.
I've worn out my rawhide mallet so I quit hammering on the pto coupling
after the first couple of weeks. Now, everytime I finish mowing I
squirt some more WD40 into the coupling--just on the off chance
something organic in the grit might dissolve or something inorganic
might shift with the bit more lubrication. Since the driveway's getting
real bumpy, I tried the coupling one more time--just on the off chance.
Voila! It practically fell off. Serendipity or ?
Thanks again for all the great suggestions.

Now, to the OP's problem.
1. WD-40 is worthless except to remove adhesive from stuff (where the
adhesive peels off the tape for example) and for water displacement.
WD stands for "Water Displacer". WD-40 is NOT A LUBRICANT, nor is it a
penitrating oil. Never was, never will be.
2. The stuff I use is called Kroil. In a spray can usuallyi called
AeroKroil. Very good stuff, designed and made for this task.
3. You can make your own penitrating oil, too... I use frequently a
50/50 mix of diesel and ATF. Mix well. The diesel and ATF both have
lubricating qualities, both penitrate well.
4. Get a 'dead blow' hammer.
