Maintenance Tips
- Belt Replacement: Inspect belts regularly for wear and tear. Replace the deck belt every 200-300 hours of use, or sooner if cracks or fraying are visible. The drive belt should be checked and replaced as needed.
- Blade Sharpening: Sharpen mower blades at least twice per mowing season, or more frequently if you mow in sandy or rocky conditions. Dull blades tear the grass, leading to unhealthy growth.
- Filter Changes: Change the engine oil and filter every 50 hours of use, or at least once a year. Clean the air filter regularly and replace it annually or more often in dusty conditions.
- Seasonal Storage: Before storing your D110 for the winter, stabilize the fuel, change the oil and filter, and disconnect the battery. Store the mower in a dry, covered location.
