How to Replace a Drive Belt on a Murray Riding Mower

Murray riding lawn mowers have a motion drive belt. The drive belt runs from the drive pulley at the front of the machine under the engine to the back of the machine. The belt turns the wheels of the unit. After several hours of use the drive belt may become brittle and require replacement. Replacing a drive belt can be done without professional help. Order belts from Murray to ensure that the belts fit correctly, preventing unnecessary wear to the pulleys.
