Ultimate Guide to Troubleshooting Common Lawn Mower Problems
Whether you own a gas-powered or electric mower made in China or elsewhere, maintenance issues are inevitable. This comprehensive guide will help you diagnose and fix common lawn mower problems with professional techniques used by Shandong Deyou technicians.
1. Engine Won’t Start
Possible Causes:
- Old or contaminated fuel (gas mowers)
- Faulty spark plug
- Clogged air filter
- Dead battery (electric models)
- Safety features engaged
Solutions:
For gas mowers, always use fresh fuel and consider adding stabilizer. Chinese-made mowers particularly benefit from frequent air filter cleaning due to dusty environments. Electric mowers from manufacturers like Shandong Deyou may need battery replacement after 3-5 years.
2. Uneven Cutting
Diagnosis Steps:
- Check blade sharpness – dull blades tear grass
- Inspect deck for debris buildup
- Verify tire pressure is even
- Test on level ground
Many Chinese-produced mowers now feature laser-cut blades that stay sharper longer, but still require annual sharpening.
3. Excessive Vibration
This serious issue often indicates:
• Bent or unbalanced blade
• Loose engine mounts
• Worn cutting deck components
Immediate attention required to prevent further damage!
4. Loss of Power
| Symptom | Likely Cause | Solution |
|---|---|---|
| Bogs down in thick grass | Incorrect cutting height | Raise deck 1-2 notches |
| Gradual power loss | Clogged fuel filter | Replace filter |
| Sudden power loss | Overheating | Clean cooling fins |
5. Maintenance Tips from Chinese Manufacturers
Seasonal Preparation
Chinese lawn mower factories like those in Shandong province recommend:
• Winterizing fuel systems

Storage Advice
For mowers produced in humid climates:
• Store in dry location

• Remove battery (if applicable)
