Tying down the clutch pedal?

My 960 pto clutch doesn't disengage fully. I re-adjusted the pedal to exactly what the manual said in regard to free play and pedal height. Still the same...tremendous grinding when trying to engage pto with brush hog attached.

I can throttle the tractor down and jam the pto engagement into place with a little grinding, but there is obviously a problem here.

I saw reference to tying down the clutch pedal to alleviate this problem. What the heck does tying the clutch pedal down do?

Thanks. Bear with me here guys, I'm new to this tractor business.

If the clutch is dragging you should be able to see the pto turning when the clutch is down and nothing is connected to the shaft. It would jerk if the disc is warped. The problem also could be worn gears etc. in the drive. Sliding gears can stop in positions whee they are hard to engage. Sometimes feathering the clutch and waiting a few seconds will reposition the gears into positions that are easier to engage.

Large cutters have a lot of inertia and it makes engaging pto's difficult since they have to go from stop to pto speed instantly against large inertia. Engaging at low engine rpm's is easier. People without pto safety switches have been known to start the tractor with the pto engaged and the clutch down when using a big cutter.

I guess what this tying the clutch buz is engaging the pto without the cutter attached, tying-down the clutch to stop the pto and then attaching the pto shaft. There is a definite safety problem here and it's something that nobody should do EVER.

Could also be that the clutch is stuck. Had that happen on my 860. Or it could be worn out clutch. Most likely is coming apart anyway to fix it.

Are you sure that you have the clevis in the correct hole on the clutch rod so that your 2nd stage of your clutch is releasing?

Pretty sure. I never dug into it to actually find out what happened. Tractor has been sitting a few years now, for other reasons. Not really much use for it, other than a novelity. Last time we fired it up, it had sat all winter, and the PTO clutch would not disengage. Since it had worked perfectly before that, I came to the conclusion it was stuck. I'm after forgetting now, but I think that the first stage was also stuck. But, like I said, I never bothered to actually take it apart and find out what was wrong. It's one of those things on the list.... Major restoration upcoming, when I actually have some time and money to put into it.

If you had the problem before, and now are storing the tractor long-term, by all means tie the clutch down! This will keep the disks apart & it won't freeze up.

A little use now & then will add life to your tractor.....

Two different issues.

Tie the pedal down if your clutch likes to rust together & you are leaving the tractor sit for a long period.

Sounds like your clutch is wore out & needs replacing.

Ummmmm mmm, correct me if I'm wrong, but a clutch that won't disengage in NOT a wore out clutch. One that won't ENGAGE is the wore out clutch.

get the pto in gear, let the mower catch up (no override clutch on it), push the clutch all the way in, and shut the engine off before the mower comes to a stop. IF it keeps turning, the clutch is free.

May need a little tweek from the manual, they're a good guideline, but not the bible.

I see what you are saying, but if you reread his message, he is actually having trouble getting the pto into gear - but it does with some grinding. If he got the linkage all adjusted to spec, then it probably means that the clutches are worn out.

Now, if the problem were that the pto would not _ever_ go into gear with the engine running, then it is a chance that the plates are rusted together. Then tying the clutch down will help in the future, once you get them jarred loose again.

To me, it sounds like a bad clutch.
