Maintenance Tips
- Belt Inspection & Replacement: Regularly inspect belts for wear and tear (cracks, fraying). Replace belts every 2-3 years, or sooner if damaged, to ensure optimal performance of the mower deck and drive system.
- Blade Sharpening: Sharpen mower blades at least once a season, or more frequently if you mow in sandy or rocky conditions. Dull blades tear the grass, leading to brown tips and a less healthy lawn.
- Filter Maintenance: Change the engine oil and filter annually. Clean or replace the air filter regularly to ensure proper engine performance and longevity.
- Seasonal Storage: Before storing your John Deere 108 for the winter, stabilize the fuel with a fuel stabilizer, disconnect the battery, and store the mower in a dry place.
