Okay, time to get this figured out

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.
 
I would take a peek through the inspection cover to determine if
it is mechanically trying to release. Of course you will need a
helper.

Breaking a frozen clutch disc free requires it to be in the released
position for any results. I'm still trying to figure out how you plan
to accomplish this with the mower.
 
If it's just the disc frozen to the flywheel, then there should be no clutch pressure on the disc when I step on the clutch pedal. With power to the mower and no pressure from the pressure plate then the only thing holding the disc to the flywheel would be the rust/moisture of the disc to the metal of the flywheel. My experience with crawlers shows steering clutches doing the same thing usually break loose with that type of pressure.
 
I would first try to determine that the mechanics are working properly, nothing broken inside,

if ok.



Then find the heaviest thickest pile of weeds and grass you have, lower the old hog down and pull the ears back on the 65. Push the clutch in and let it set there and chop it up.

As others have said, each time you push in the clutch you stop the forward motion of the tractor.

Now this is real KY redneck: with tractor in neutral, you pushing down fully on the clutch, but hog running full out in heavy grass, have your buddy pull you with another tractor.

This would allow you to put pressure on the stuck clutch plate with the mechanical released.
 
Have you pulled the bottom cover and checked the
clearance of the three adjustment capscrews? New is
.080-.090" (depending on what book you read), try
setting them down to .050".
On my 65 I would engage the PTO with the tractor off
with the baler hooked up, then start the tractor
(bad practice I know but I was trying to solve a
problem, not bale acres of hay). Figured the
plunger cycles would free it but no joy. Had to
split it and replace an oil soaked disc.
 
Thanks anyways Brendon but I'm as broke as can be after putting the clutch in the DB990. I'm going to see what happens and check those clearances as soon as I get a chance. I've got a yard full of dead equipment at the moment!

You'd think there'd be signs of problems if things were wearing out. This happened without warning, just like all my other stuck discs. I dunno.

Hey, nice little storm last night, eh? Gonna have to to figure out how to put pontoons on the haybine, rake and baler at this rate!
 
try adjusting the 2 stage clutch, remove the plate under the clutch housing there are 3 bolts spaced equally around the pressure plate between the main drive plate and the pto plate adjust the gap between the bolt heads and the plate to approx. .090 most of the time that's the problem because as the drive disc wears away the distance between the bolts increases to the point that they can no longer release the pto clutch
