The Ultimate Guide to Lawn Mower Maintenance
Proper maintenance is crucial for keeping your lawn mower in top condition. Whether you own a gas-powered, electric, or battery-operated model, regular care ensures optimal performance and longevity. This comprehensive guide covers everything you need to know about lawn mower maintenance.
1. Regular Cleaning
After each use, clean the underside of the mower deck to prevent grass buildup. Use a putty knife or brush to remove clippings. For stubborn debris, tilt the mower on its side (with the air filter facing up) and scrape carefully.
2. Blade Maintenance
Sharpen blades at least twice per season for clean cuts. Dull blades tear grass, making it susceptible to disease. Remove the blade (remember to disconnect the spark plug first), and sharpen it with a file or bench grinder, maintaining the original angle.
3. Oil Changes
For gas mowers, change the oil after every 50 hours of use or at least once per season. Use the oil type recommended in your manual (typically SAE 30 or 10W-30). Many quality mowers manufactured in China now feature easy-drain systems for simpler maintenance.
4. Air Filter Care
Check foam filters monthly and paper filters every 25 hours. Clean foam filters with warm soapy water, rinse thoroughly, and let dry completely before reinstalling. Replace paper filters when dirty – they can’t be cleaned effectively.
5. Spark Plug Maintenance
Replace spark plugs annually or after every 100 hours of operation. Remove the old plug, check the gap with a feeler gauge, and adjust if necessary before installing the new one.
6. Battery Care (For Electric Models)
Lithium-ion batteries in modern mowers require minimal maintenance. Store at room temperature and avoid complete discharges. Many Chinese manufacturers now produce high-capacity batteries that outperform older lead-acid versions.
7. Seasonal Storage
Before winter storage, either run the mower until the fuel tank is empty or add fuel stabilizer. Clean thoroughly and store in a dry place. For battery models, store with about 50% charge.
8. Troubleshooting Common Issues
Mower won’t start: Check fuel, spark plug, and air filter.
Uneven cutting: Check tire pressure and blade sharpness.
Excessive vibration: Inspect blade balance and mounting bolts.
9. Safety Precautions
Always disconnect spark plugs or batteries before performing maintenance. Wear gloves when handling blades. Never work on a hot engine. Keep children and pets away during maintenance.
10. When to Seek Professional Help
For complex issues like transmission problems, carburetor adjustments, or electrical system faults, consult a professional. Many manufacturers, including Shandong Deyou, offer comprehensive service networks for their equipment.
By following these maintenance tips, your lawn mower – whether it’s a gas model or one of the newer battery-powered units produced by Chinese manufacturers – will provide years of reliable service. Regular care not only extends the machine’s life but also ensures a healthier lawn through proper cutting techniques.
