Maintenance Tips

Belt Inspection: Regularly inspect the deck belt for wear and tear. Replace the belt every 2-3 years, or sooner if cracks or fraying are visible.
Blade Sharpening: Sharpen the mower blades at least once a season, or more frequently if you mow in sandy or rocky conditions. Dull blades tear grass, leading to disease.
Filter Changes: Replace the air filter annually, or more often if you mow in dusty conditions. A clean air filter helps maintain engine performance.
Seasonal Storage: Before storing the mower for the winter, drain the fuel or add a fuel stabilizer. Clean the mower deck and store it in a dry place.
