That happened because it was not adjusted correctly.

I'm a fan of the bolt-in button too. Wrecked and lost a push-in bronze button in 30 seconds . . . loose hole in the clutch release arm. it is also critical to have the button centered on the PTO center button, and to have the center button centered in the PTO. The early PTO style with the curved tips on the spring located the center button precisely; the flat double springs can wander based on anything that happens. I've lost quite a few bronze buttons and center buttons because of that, also the three small clutch release springs that go on the bolts were soft (1-1.5mm shorter than new), and that also seems to influence things. Make sure you remove all side-to-side play in the clutch release arm, so that it can't move off-center on the PTO center button. I'm ruminating on how I can "locate" the center button so that the clutch fingers don't slip off the edge of the groove in the center button . . .

there's no reason for the wear button to disintegrate unless the button in the center of the clutch engagement fingers is all buggered up or worse, missing

Well I fired up the cub for first mow of the year and my manual pto isnt disengaging. There is plenty of pressure on the release button, but it still spins. Can someone explain how the clutch actually works? In other words which parts grab and don’t grab based on if the button is in or not in. That might help me troubleshoot. Thanks!

Thanks do you have illustration 2-97, still don't know what the "friction disc" is. I did trace my problem to a fatigued [ressure spring though (I think)
2-97 is in the link I sent you, and this is a friction disc.
