First In used the clevis adj . I have the fingers at less than one eight inch from the bearing. Then I used the procedure provided above. I moved the adjustment (#6) one half turn(loosen). It did not help then I moved the adjustment one full turn. It did not help . Then I moved the adjustment two full turns . I still had grinding when I tried to engage the pto. I put the adjustment bolts back where they were in the first place . At this point I can engage the pto before starting the tractor and use the pto. If I start the tractor I can not engage the pto. Any ideas

I think you went the wrong way on your #6 adjustment. You loosened, but Spiker loosened because PTO engages late relative to pedal release stroke. Yours is early (to hear you tell it,) so early that it is engaged before you let the pedal up at all (thus the grinding.) Your complaint is the opposite of Spiker's, but you adjusted the same direction if I am understanding you and the situation correctly.

Therefore you should close more of the gap in the #6 area, not make it larger. Get that right (about a 0.014" (fourteen thousandths) and once it is right, you have done about all you can do but adjust the clutch bolt stopper bolt in a bit (and adjust the clutch safety switch too.)

If all else fails and every thing is right, I guess you could verify for sure that your spring pins are not broken or wore.

Or ...hook it up to a hard, high inertia load, and start and stop that load several times using only the clutch to polish and run things in a bit. Remember, engine running fast, the clutch pressed full in, but the brushcutter not turning should polish it a little if needed or helpful. Whenever I get to the point you are at (if I am not luckier) I will most definitely practice what I am preaching.

I am out of ideas beyond that, unfortunately.

The finger gap just is. It should be 1/10 inch in a hard case like yours.
The bottom of pedal for the main clutch is set by the #6 gap and the bottom of pedal for the PTO is set by the clutch arm stopper bolt. If a clutch is grinding, you need a lower bottom/stop for that clutch. But that doesn't mean just any amount of lower bottom. You need the exact amount needed for the gears not to grind.

Set #6 until the mains just don't grind, and set the stopper bolt until the PTO just doesn't grind. Overkill on the not grinding adjustment is wasteful of not only available stroke, but your leg energy.

I would say try the 1/10 inch and the 0.014" settings to start. If the PTO grinds, check the stopper bolt.

If none of that helps, live with it, split it, or take it to a dealer, listen to someone smarter than me.

Edit:I think you declared success while I was writing the above. Congratulations!
