Massey TO35 PTO slipping

Today I put my tiller on my TO35 and as soon as it gets in the dire the PTO starts slipping. Is there any adjustment or anything I can do to this or does it now need a clutch? I seen something about removing a plate and draining off oils that had gotten where it doesn't belong, but that was on a different model, does that also apply here? Any help would be appreciated. Thank you, Bud

Is your tractor the deluxe model with dual clutch? If so, there is an adjustment for the PTO clutch.

There are 3 hex bolts that release the PTO clutch. There should be .090" clearance between the head of the bolt and the pressure plate. There is a small inspection cover on the bottom. I've never tried to adjust one, it will be tight quarters but should be possible. Typically that adjustment is made when the new clutch is installed, before the tractor goes back together, and typically the main drive clutch wears much faster than the PTO clutch. So, if that gap is closed up, it was probably not adjusted when it was last apart.

There is a drain hole in the bottom of the bell housing, should have a cotter pin in the hole to keep it free of dirt. If it's clogged, the clutch may be oil soaked. When you take the inspection cover off it will be obvious. Oil gets in from the engine rear main or the transmission front seal. If you do have to replace the clutch, would be a good time to replace the trans seal, it's easy.

Steve, Thank you for the input. I did not find a drain with a hole in it. The only drain I am aware of I on the bottom but side of the bell housing. Didn't see any pin holes in it. Also I don't have a cover on the bottom side. I do have the dual clutch. Another piece of info for this. I noticed this winter when I would go to pick up my blade, that it would not lift when I had the clutch in. In the past it would. I am guessing the hydraulic pump is tied in with the clutch for the pto and that makes the connection between these two issues. So back to your comment for the adjustment. Please see the attached pictures and let me know if you see a cover where I could access the adjustment. Any other help would be greatly appreciated. I have had the tractor about 20 years but it has always held up well so I haven't had to do much work on it. Not a tractor mechanic by any means. Thanks again, and I greatly appreciate your help.

If you can't find a drain hole someone has removed the cotter pin and it is plugged.

Gentlemen, Thanks again for the input. I had another look tonight and found the hole. The cotter pin was gone and the hole just blended it so I didn't see it last night. So I took a screw driver and cleaned out the hole, then about a quart or more oil came in. So it sounds like you were right on. I used the tiller tonight just to see if it would clean up and hold better. Seems a little better but definitely not like it used to be, before this happened. My question now is, if I take the inspection cover off, would I be able to spray the clutches down with brake cleaner from there, or would I be able to get to anything with it? I expect over time it may just wear off and get better, but if I could help it by spraying it down, I would give it a shot. What do you think.
Again, I can't thank you enough for the help. I don't know how many times this website has helped me. Thanks, Bud

I am not familiar with the MFs, but I expect that a quart of oil would be deep enough to soak the clutch discs. It would be worth a try to clean them with brake or carb cleaner, if the inspection hole gives you access.
