new owner needs PTO help

[JC-jetro]

Hey....had to go out of town on business.....

I'm back and going to take the tractor by the shop tomorrow

They seem to think that the clutch is stuck.

Apparently this happens often enough that ford put a small lever on the back side of the clutch pedal, so when stored for lenghts of time the clutch can be locked in the disengaged position.

The service manual costs $200 plus dollars....It is going to be cheaper to let them diagnose the problem.....go figure

the PTO will engage with no load on it......it will also engage under load as long as the end shaft is spinning at a reasonable speed.

A block of wood (small chunk of 2x4) is what I use.

Your observation reveal a different thing to me. If PTO engages with no load on and it leads me to believe that mechanical linking (sliding coupler) between PTO input shaft and PTO final shaft is okay and it stays locked in.

Your observation that PTO under load only spin at certain rpm ( or torque) leads me to believe that your pto clutch is actually slipping and not able to maintain the torque required by rotating implement. That is caused by either worn out pto clutch disk or adjustment. if adjustment is bad, it is likely yo have some issue changing gear as well. There is only one clutch release fork. Do you have grinding when you change gear?

Hopefully adjustment is all you need although your observation does not fully support it.

no slipping/grinding in any gear.....The only grinding is when I try to throw the lever in to engage the PTO....I grinds like ****, but if I force it the PTO will engage....once the PTO is spinning(bush hog attached) the PTO works fine....It will go in and out of gear....no problem no grinding at all, but the shaft must be spinning....so I guess you're right....the clutch is probably slipping.....Now...do I take it to the shop or attempt this adjustment myself.

Sean,

Your statement and observations are not all conclusive. I gathered from your previous posts that with grinding of pto engagement once you force it engaged then the pto under load stops working.... that indicate slippage.

Here, in this post you're saying once you passed the dang grinding the pto continues to operate that indicate pto being stuck.

Adjusting the clutch will not unstuck the clutch disk. do the following test with the help of someone and with the engine "off".Engage the pto, try to turn pto, it only should turn in one direction. Have someone to push the clutch pedal all the way in while you are trying to rotate the shaft in the direction that it does not turn. if pto starts turning by clutching it indicates the pto disk in not sticking. If Pto final shaft doers not turn with clutch fully depressed then you have sticking clutch.

There is cure for sticking clutch and a method to adjust the clutch, two different things. Do the test and report back.

you got nothing to lose by trying to adjust if you need to. Again by adjustment you only make the release fork either closer or further from pressure plate fingers and that's all. That can not fix physical issue with slipping or stuck clutch disk and in your case disks.

You can find the service manual on ebay for under a 100 bucks. Then you will have a manual to help when you have future problems. If you take it to the dealer and adjustment doesn't fix the problem they will probably want to split the tractor $$$$. A dealer usually wont try the methods to free a clutch that you can for liability reasons.

Almost sounds like adjustment,,,,maybe not.

The 2 times I've played w/ rusty clutches that were stuck together we attempted some kind of a burn off. Meaning we on purposely tried to burn the clutch by riding it against a tree or something once we unstuck. Seemed to help.

Deep grass and a knowledgeable clutch foot might help in your case.

Lots of times the external diagnosis is a stuck PTO disc. Often the root cause is a worn transmission disc that screws up the pressure plate linkage geometry preventing the PTO stage from releasing.

Well I figured out the problem.....Actually my mechanic did.

The amount of travel in the pedal just needed to be adjusted out...plus the linkage rod was bent and needed to be straightened out.....

Cost me $10.....

I'm very lucky.....and I appreciate everyones help.......

Cool that's what I was hoping and no need for a tractor split. I hope this gave you an opportunity to dig in to it a bit and learn something. So your clutch was not slipping and was sticking. it was sticking not because clutch disk was stuck to the flywheel but because the clutch pedal did not release the clutch fully and all the way. Pedal travel was enough to completely engage the transmission clutch plate but not the pto. Nope, can't say it twice in a row
