I own a 16.5 horse power riding prairie mower and have problem? I was mowing my lawn and partially way finished with the meadow...

I was mowing my lawn and partially way finished with the meadow and heard a click and the mower stopped going. It was still running and the blades still work but will not move forward or backwards. Any suggestions?
How complex is it to transform a belt...
Answers:    I don`t know the drive belt broke or came off pully
Frost contained by the attic?
On my Sears riding mower the prevalent drive belt falls off the pulley. Underneath the Sears there are two belts, the one that go from the engine pulley to the rear wheels is the "go" belt. See if this belt slipped bad or broke in two.
I have to depress my clutch contained by order to re-install the belt back on the pulleys Read your owners brochure, you may find a drive sheer pin in the power train. That would explain the click you heard, bar that IDK.
