Installation & care tips
Before installation, disconnect the mower’s spark plug or power source, remove the old belt, and inspect pulleys and blades for wear or damage. Confirm the belt routing matches your mower’s manual, then install with the belt seated firmly in pulleys. After installation, run the engine briefly to check for correct tension and smooth operation, and replace any damaged pulleys or guards if needed. Routine inspections during the mowing season will help extend belt life and maintain optimal performance.
