Dude, I had the same problem. And when I got under the mower to fix the thing, there is a diagram of the belt routing for the drive under the RIGHT hand floorboard... kinda like a sticker or something. And the belt routing for the blades on the mower deck is another diagram located on the LEFT hand floorboard... where you put your feet when mowing. So get down on the ground and look up at the underside of the floorboards. That should help...
