Mower won't drive, but motor runs and blades spin

I was mowing with my one-year-old Craftsman Z600 (zero turn) for the first time this season, and about 20 minutes in, it stopped in its tracks. The engine and blade were still going, but the wheels would not spin when I gave it throttle. Tried again a little later, same issue. Both belts are intact. There was no impact or funny noises. The only issues that come to mind:

-Gas is a little old, but the engine is running fine and it starts right up
-There were some twigs and acorns rattling around the deck when it stopped, but nothing serious, and why would that affect the locomotion anyway?
-It's about 10 hours overdue for an oil change

I don't even know what else to check - any thoughts?

Thanks in advance!

Check that the bypass valve has not worked itself open
check that the belt is actually running on all the pulleys and has not slipped between a pulley & fan.
Check the tensioning arm is holding the belt tight.
Get some one to move the lap bars and check they are activating the drives.
