So I'm about to lose my dang mind here with my mechanical PTO.
When engaged, there should be a 1/64th-3/64th inch gap between the wear button on the PTO lever and the thrust button in the PTO, per the instructions on the very last poorly xerox'd page here:

I've adjusted it so that when it sits in the "PTO engaged" position that I can barely slide a .001in feeler gauge between the buttons. When I disengage the PTO the buttons touch.
When I start the tractor with the PTO disengaged, the PTO begins running the moment I crank the engine.
Nuts!
OK so I adjust the arm closer to ensure the buttons are snugly engaged. Now the PTO stays disengaged when in the disengaged position. It engages when commanded to, but now the buttons are touching while the PTO is engaged. 5 minutes into a snowblowing run and the PTO starts grinding and warbling something fierce, like a blender gone bananas. I hop off and check and the wear button is worn away, and the thrust button is throwing sparks off the metal engagement arm.
Nuts!
What the hell do I need to adjust and how do I adjust it once I get my new wear button delivered?
All this and tomorrow we're due for 6 inches of snow. Guess the snow thrower will have to act as a snow plow temporarily.
