How to find the right belt size for craftsman riding mower?

To find the right belt size for a Craftsman riding mower, first consult the owner's manual, which typically includes the correct part number and specifications for the belt. If the manual is unavailable, measure the old belt's length and width or check the mower's model number online for compatible belt sizes. Additionally, you can visit a local hardware store or parts supplier with the model number for assistance in selecting the right replacement belt.
