Rear engine Craftsman runs but doesn't drive wheels after loud pop/bang

Model No. 502.256220 Sears Craftsman riding mower with rear engine

When mowing over some tree roots and being jostled around, there was a noticeable bang/pop sound from behind me, and the wheels stopped driving forward. I suspect something is broken in the transaxle....but what? My wise neighbor says that it should have been a cotter pin that broke. Looking at the transaxle schematic, I don't see any cotter pin, but there are clutch keys and a woodruff key in some gear assembly. The belt is not broken. The engine runs. The clutch feels normal. The gear selector feels normal.

What do you folks think?
