Wide frame pto clutch

[brentwd]

I have a question on a 129. This may apply to all tractors with a manual pto. Is the clutch suppose to turn when there are no belts attached to it when the engine is running? If I try to adjust the rod to keep it from turning while the engine is running it does not release far enough and rubs on the button.

Yes it will turn. If it still turns when you stop the motor, then there is a problem. You should not have to adjust it. If properly done, there should be the thickness of a matchbook cover between the button on the PTO arm and the PTO button. I always engage the PTO handle when I am not running a belt to it.It keeps the fiber button from premature wear...

Thanks. Thats what I was thinking about doing.

Most people will actually engage the PTO when they don't have a belt on it, to keep from wearing out the PTO button. It won't hurt a thing to let it run with the engine.

The button is missing on the 149 that I just bought. Is it as simple as releasing the PTO arm and putting the button in there? Or is it likely missing a whole bunch of parts?

If it is the fiber button on the release arm, you should be able to press it into the arm or use some RTV silicone to hold it in place.

If it is the metal button on the PTO itself, you will need to remove the PTO to install the button. You will have to take everything loose to fit the release arms of the PTO into the button then have the little metal gauge to set up the correct tension on the arms. It would be a good time to just go ahead and rebuild the PTO.

Though it may be the correct one, that was not the answer I was looking for.

Steve,
If you are missing the fiber button,that is an easy fix.I would pickup a few in case your first try is not successful.
If you have the brake style pto and you think you are missing parts post a picture of what you have.
For now here is how I install one on a non brake style.

Most times the Pto arm will still have part of it still there.Remove the grill and engage the pto and get a small punch to knock out the remaining piece.When you install a new one,clean out the hole with a rolled up piece of 220 sandpaper.Then slightly taper the stub on the button to help start it in the hole.Now some say to pull back on the pto handle to drive the button in the arm,more than likely it will break, I prefer using the turnbuckle on the pto to set it.Just loosen the lock nut and start pulling the arm towards the pto. If there is still some space between the button and the arm,just tap the arm slightly while the pto is still engaged till it is flush.
Now disengage the pto and adjust the arm until you can fit a matchbook cover between the buttons.

Thanks Lew.
I haven't had a good look at it yet and as usual I am at work now. I spent some time studying the PTO pages in the service manual today and now I have a better understanding of what to look for. As I recall there is a little bit of the button still on the arm. I don't think the PTO was used much on the tractor because the mower is in very good shape and the PTO pulley has some surface rust on it. For the short time I had the engine running the pulley was turning. I guess that might be a good sign. I'm going to concentrate on getting it running and driving before I move on to the PTO. Mine is not the style with the brake.

Brilliant!
