NH #3930 PTO HAS QUIT

[HickoryNut]

Try disconnecting the engagement lever from the splined shaft, rotate a little, then reconnect it.. might give a little more life to a damaged clutch. If that works then fine-tune adjust it to where engagement takes place at about 2/3's of the throw distance between stopped and spinning, then re-adjustment the "slip" bump stop.

That lever is worrisome, I've never left mine at the "slip" detent, but I have knocked it off of full engagement many times with my leg.

That's absurd. Do you have any idea how the PTO clutch on a 3930 works? The lever operates a hydraulic control valve spool. Altering the stroke of the spool can do nothing but degrade clutch operation, one way or the other.
