So, my 65 has had this problem for a while. The PTO clutch disc is probably stuck. Last year I ran the round baler with the 65 and the PTO would shift in an out with no issue. Then it went on bale spear duty and I didn't use the PTO at all for several months. This winter when trying to use it on the spreader I found I could not put the PTO into gear, the 540 side, with the tractor running. I had thought it might have been ice and mud related but I've cleaned her all up and the linkage all looks to be working right. The tractor idles down to barely running. Having just had a stuck clutch on another tractor it occurs tome that a stuck disc is the most likely culprit. The PTO stays engaged when I step all the way down on the pedal if I start the tractor with the PTO engaged.
With that in mind, any reason not to try using something like a bush hog to break it loose? That seems like the implement I have that's most likely to offer the resistance needed.
