Maintenance Tips

Belt Inspection: Regularly inspect the mower deck and drive belts for wear and tear. Replace belts every 200-300 hours of use, or sooner if cracks, fraying, or slippage are observed.
Blade Sharpening: Sharpen the mower blades at least twice per season, or more frequently if you mow over sandy or abrasive terrain. Dull blades tear the grass, leading to an unhealthy lawn.
Filter Changes: Change the engine oil and oil filter every 50 hours of operation. Replace the air filter annually or more often if operating in dusty conditions.
Seasonal Storage: Before storing the mower for the winter, stabilize the fuel, change the oil and filter, and disconnect the battery. Store the mower in a dry, protected location.
