John Deere Riding Lawn mower starts, but won't go into forward or reverse?

I finished mowing the lawn a couple weeks ago and throttled down... when I throttled down I heard a clunking sound as I was turning the motor off... as it finally turned off, I started it again to make sure everything was ok, but it no longer would go into forward or reverse... I don't know what model it is... It's about 5 years old, not a zero turn, doesn't have gears, just forward, reverse pedals and parking brake on the right side. Any help would be appreciated.
I checked the pull tab on the back, it's not that... belt isn't broken...hmmm....

Check the drive belt on the bottom. It is probably broken....
