I was mowing with the bushhog and when I shut off the PTO and idled it down it kept turning and would not disengage until I shut it off. It made some clanky gear noises for a second at shutoff. Haven't used the PTO since but everything else seems to work. Now what?

With engine off can you turn the PTO shaft more than just a few degrees in both directions before it stops? If yes, then the plates are PROBABLY okay, and the brake disc is still functioning. On the other hand, if it won't turn at all without the engine turning then the clutch could be locked/jammed up and the brake disc may have been the clanking you heard.

It'll move freely about a quarter turn. Is that normal? thanks

Yes, it should move about 1/4 turn until the brake plate hits the main case and stops the shaft from going any further. I guess at this point I would briefly try the PTO again and see what happens.
