Alliss Chalmers 6060 pto clutch problem

Hello everyone. I bought a AC 6060 and left the hand clutch disengaged, pulled back for some time. I had the lever on the left seasonal PTO disconnected. Now I tried using the PTO it will engage but I can`t get it to stop turning with the hand clutch.
Cable moves clutch arm maybe 1/4 inch but won`t disengage.
Trying to brush hog Can I start the engine with the brush hog hooked up and the PTO engaged? Help!!!!!
Thank you

Maybe someone else can tell you better, but I had a
6140 with the same setup. I could adjust the amount
of free play on the cable to make it move the clutch
fork more.

It's been a long time, but I will recall what I can. That set up was the major problem with those tractors. The PTO clutch system, if left with the lever latched to the rear, would push the crankshaft forward through the thrust bearing, until major engine damage resulted. That's why they offered the retrofit, external, front mounted, Timken, greasable thrust bearing.

As I recall, you were supposed to be able to pull the PTO clutch lever back, with the engine running, pull up on the PTO shifter to engage the drive line, then release the clutch lever forward, engaging the PTO. As I remember it never worked that way, without grinding the shifter. And as I recall, you couldn't start the engine with the PTO shifter engaged, because of a safety switch.

You could have any number of problems, with worn linkage, clutch, bearings, cable, etc. Anything hooked to the PTO ought to offer enough resistance to stop the PTO. If you're fortunate, some adjusting might remedy the situation. If I had kept the tractor, I would have bypassed the safety switch on the PTO shifter, so that I could start the tractor after pulling the clutch back, and engaging the shifter. Then I would still use the clutch lever properly, leaving it forward as much as possible. I wouldn't be trying to start the tractor with the PTO engaged and hooked to an implement.

Morgan,
There are stops on each end of clutch arm. they are moving enough to touch them.
Thanks

Bob,
Should I try to start it with brush hog hooked up but with the hand clutch pulled back (disengaged)
Thanks

You could try that. If the clutch is releasing at all, maybe it will slip enough to let you start up. Must be the safety switch on the PTO shifter is no longer operable? (If I'm remembering correctly how it works).
You mentioned the "seasonal" disconnect. That's not the intention. It's supposed be disconnected whenever the PTO is not in use. Likewise, the clutch lever is supposed to be forward as much as possible.

first, the pto clutch should always be left in the engaged position with the left hand transmission engagement lever in the off
position.
Second check the clutch clearance regarding the external thrust bearing "addition". The specs can be obtained from your local
friendly AGCO dealer along with the assorted shims.
Third, if the PTO clutch has been left in the on position.. a somewhat stupid decision, then maybe it's stuck/frozen to the
flywheel.. and you may need to break it free..using "whatever".

I own a 6080. I keep the external thrust bearing clearances to factory spec, disengage the PTO gear train and engage the clutch
after each use.. even when returning from the field.... chopping..spreading manure, baling, et al...

It may be considered a pain .. but that's what you need to do.. I bought my 6080 with 3250 original hours 15 years ago.
.. adjusted the external thrust washer/bearing and continue to lube and check it..

but you must read the operators manual..

Thanks for the info. Any ideas on getting it unstuck from flywheel
