• Enhances Safety: A loose belt can detach while the mower is in operation, posing a safety hazard.

Benefits of Tightening the Blade Belt

Tightening the blade belt offers numerous benefits, including:

• Extended Belt Lifespan: Proper tensioning prolongs the life of the belt, saving you replacement costs.
• Improved Cutting Quality: A tight belt ensures optimal blade rotation, resulting in a more precise and even cut.
• Reduced Wear and Tear: Correct belt tension minimizes stress on other mower components, such as the engine, pulleys, and spindles.
