TC35D PTO won't stop turning

[jinman]

I suppose getting this issue corrected is going to take a trip to the dealer. Anyone have any idea of what this entails or costs?

Tom, I think the dealer will first remove your seat where there is an access port to the PTO control valve and cover plate on top of the rear transmission. He will remove the valve and plate and inspect your PTO clutch. If it is only a damaged stopping plate, that can be replaced without removing the entire clutch.

If the complete clutch has to come out, the Repair Manual calls for splitting the tractor between the front transmission case and rear transmission case so the shaft the PTO mounted on can be driven out the rear of the housing to allow the clutch to be removed. This is a much more critical issue than just replacing the stopping plate.

I don't believe the dealer will be able to tell you how big a job it will be until he gets the cover off the transmission and inspectes the parts.

I've uploaded two diagrams. The first one shows how to access the PTO valve through the access under the seat. The second shows the plate the PTO valve is mounted on and what the clutch looks like with the plate removed. The flat plate on the top of the PTO clutch with the notch in it is the PTO stop plate and what may be damaged on your tractor. Of course, it also might be ear on the PTO that slides into the slot. That would mean the whole clutch has to be removed.

Holy moly that looks like it could run into a lot of money. I guess I'll need to think about that one. If I don't do this am I doing more damage? It is really a minor annoyance right now. thanks for the replys.

Well, it might get worse since everytime you turn off the PTO, the ear has to "find" the slot and drop in. If the slot has become rounded or the ear worn off, it will only get worse. Also, while having your rotary cutter hooked up, you can stop it's motion by lowering it to the ground, but what about something like a post-hole digger or tiller? The fact that these will spin all the time could be dangerous, especially a post-hole digger. So, depending on what attachments you have and use with the PTO, you will have to make the decision on how critical the repair is.

tly,

You're right--pretty expensive (I believe just under 2,000). I've had to do it. Same symptoms. I do very little brush hog (5') but lots of 7' finish mower. I usually (slowly) engage/disengage mower in mid-rpm range, but perhaps that's still too much strain on the mechinism.

Since I rely on the tractor for home and some business, I had mine done after about a year of putting up with the PTO always turning. My dealer said it was just a matter of time until it failed.

JINMAN is probably right on with his assessment.

Yes, I should probably look into getting this fixed. The only PTO attachements that I have are a finish mower and bush hog which are both done for the year. Tobitobi, when your dealer said it was only a matter of time before it failed did he mean that the PTO would stop working entirely? If that is the case it would certainly force the issue for me.

tly,

I believe that is what he meant. It comes down to when not if, and my opinion is that I'd rather do it when I can arrange than for it to fail completly in the middle of a job or when I really need to use. Best wishes.
