Maintenance Tips

Belt Inspection: Regularly inspect mower deck and drive belts for wear or damage. Replace belts every 2-3 years, or sooner if cracks or fraying are visible.
Blade Sharpening: Sharpen mower blades at least twice a season for a clean and healthy cut. Dull blades tear grass, making it susceptible to disease.
Filter Changes: Change the engine oil and filter annually, or every 50 hours of use. Replace the air filter at least once a season to ensure proper engine performance.
Seasonal Storage: Before storing the X520 for the winter, stabilize the fuel, change the oil and filter, and disconnect the battery. Store the mower in a dry, protected location.
