3000 PTO

[morekick]

Howdy all, sure am glad I found the forums.

I proudly own a 1967 3000 diesel, she's been mostly restored from her prior gig in a broiler shed. Sure is a workhorse and we love her, it's our first tractor.

Last month I installed a bush hog for mowing our parcel and so far so good. Strong tractor, good performance. The lift arms are a little slow to go but so am I some days, and she's nearly as old as I am.

My main question for you all is on the PTO shifter - I'm having a hard time engaging the PTO with the engine running. I have the 8-speed trans., and a two-stage clutch. Maybe the PTO shifter's hung up from not being used prior to us, dunno. Can't seem to get the PTO from disengaged to engaged with the engine running.

So I start the PTO up - engaged - with no problem and set to mowing. But I'd sure like to know if there are some things I could do to enable correct operation. One of the posts I read when searching mentioned tying down the clutch pedal when not in use in an effort to break it loose. Is that valid? Also looking for any other pointers you may have.

Thanks in advance to you all.

If the PTO engages easily without the engine running, then the problem is in the clutch, not the PTO shift linkage.

Could just be the PTO clutch sticking, which blocking the clutch pedal down when not in use might help, but then again it might not, but it wouldn't hurt to try. Another trick for unsticking the clutch, if that is the problem, is to remove the starter to gain access to the flywheel and spray brake cleaner on the clutch to try to break it free. Some folks even use a penetrating oil like PB Blast, but I would be worried about the clutch slipping afterwards, but I'm a worrier.

Also could be something worn or broken in the clutch assembly itself such that the PTO clutch cannot disengage.

Howdy Morekick,

Have you checked the free play in your clutch pedal? Push the pedal down by hand till you feel resistance. Movement should measure about 1-1/2". If it's more than that, adjust the clevis in the clutch linkage.

have you check the clutch clevis pin, to make sure its in the correct hole, for pto use?

Thanks Sean, that's what I see - the PTO engages firmly when the engine's not running. So is the tractor not operating a true test for the PTO clutch to NOT engage? It'll engage & disengage smoothly when not running.

Thanks, Ed - sounds similar to what Bill says, too. Going back up to the parcel end of the month and I'll check the pedal resistance then. Good tip, thanks to you both. If nothing else, I might move the clevis position and work the pedal a bit to see if I can get some movement, and re-adjust if was correct to begin with.

I had the same symptoms once.
Lever would grind when I put it in gear. It got so I had to shut the engine off to engage it.
It still worked fine on the bush hog though.
For half the season.
Then the pto clutch failed and I had to split it.
If a guy read the manual he could probably readjust the pressure plate and get a few more years out of the pto clutch. Mine looked ok and the drive clutch was fine.
Do it on the flywheel.
But I got impatient and replaced it with one from from this site.
I will try adjusting the next one though.
If you replace the whole kit and kaboodle yourself I suggest you split it first and then order parts.
The drive clutch on those was either a 10 spline or I think 13 spline and you will need to see it to order the right one.
By the way -

The PTO clutch and the PTO engagement lever are two separate things.

The PTO clutch of the two stage clutch drives a shaft and a series of gears inside the transmission directly off of the engine spinning. The final shaft in that series has a splined end, and the PTO shaft coming out the back of the tractor has a similarly splined end on the inside. The handle that engages and disengages the PTO merely slides a splined collar on those shafts so that half of the collar is on each shaft when the PTO is engaged and the collar is completely on one shaft only when it is disengaged. The PTO clutch should separate the front of the PTO drive line from the engine so that the shafts and gears stop spinning and then moving the engagement handle should work with the engine running and the clutch pedal down just as easily as when the engine isn't running. The fact that it engages fine when the engine is not running means that the collar is able to slide properly and engage the two shafts together when neither shaft is moving. When the PTO clutch is working properly, and you have the pedal all of the way down, both shafts should be stationary just like when the engine isn't running. So the fact that it grinds with the clutch pedal down and the engine running, but doesn't grind when the engine is not running means that the PTO clutch isn't disengaging the PTO drive line from the engine properly.

That was the solution; thanks.
Here's the linkage before - I've put a white circle on the pin:

And here's the linkage after:


Near as I can figger the PO must've not had a need for the PTO, and moved the clevis to the frontward mounting hole to keep the clutch pedal lower (maybe for ease of operation).

The PTO engages now properly with the tractor running. BTW I said earlier it was a 1967; I was wrong - it's a 1966 model 3000. I confused it with a 1967 Ford F100 I'd seen on a recent road trip, still had that in my subconscious I guess. :-D

Thanks again fellers for all your help.[/img]
