Thanks to help from ptfarmer, I think I have a mid-70's 20C (235). I can engage the PTO both ways - either off tire speed or engine speed - but, when using the engine speed to mow, the clutch doesn't disengage the PTO. My neighbor has a 135 with the 2-stage clutch, so I know what that is supposed to feel like. But this tractor appears to only have a single stage clutch.
I've been shutting down the engine, engage the PTO, then start the tractor. It works, but I can't imagine it's right. There are a number of things on this tractor that have been "fixed" with a rope and missing bolts, and haven't been tightened afterward. Is there an adjustment somewhere that's wrong? Could someone have put in the wrong clutch? Is there something else?
