-
Check Your Owner's Manual: Your owner's manual is the most reliable source for this information. Locate the section on parts diagrams or maintenance, which should list the correct belt size and part number.

What if I Use the Wrong Size Belt?
Using an incorrect belt size can have several negative consequences:

Belt slippage: The belt may slip on the pulleys, resulting in reduced cutting power and increased wear on the belt itself.
-
Premature belt failure: A poorly fitting belt is more likely to break or fray prematurely, requiring more frequent replacements.
-
Damage to other components: Incorrect tension or belt size can put extra stress on the pulleys, bearings, and other components, potentially leading to costly repairs.

Inefficient cutting: The mower blades may not spin at the correct speed, resulting in uneven cuts and poor performance.

Cracks or fraying: These indicate that the belt is nearing the end of its life and should be replaced.
-
Excessive stretching: If the belt is excessively stretched, it may not provide enough tension to drive the blades effectively.
