The Complete Lawn Mower Maintenance Guide
Proper maintenance can extend your mower’s lifespan by 3-5 years. This guide covers all essential care techniques for gas, electric, and robotic mowers manufactured in China and worldwide.
1. Seasonal Maintenance Checklist
Spring Preparation
- Change engine oil (for gas models)
 - Inspect and clean/replace air filter
 - Sharpen or replace mower blades
 - Check battery health (electric models)
 
Winter Storage
- Drain fuel from gas mowers
 - Remove battery (store at 40-80% charge)
 - Clean underside thoroughly
 - Apply protective oil to metal parts
 
2. Blade Care Techniques
Chinese-made mower blades from manufacturers like Shandong Deyou require special attention:
| Blade Type | Sharpening Frequency | Replacement Signs | 
|---|---|---|
| Standard Steel | Every 25 hours | Visible nicks >3mm | 
| Hardened Alloy | Every 50 hours | Cracks or bends | 
3. Engine Maintenance (Gas Models)
Oil Changes
Change oil every 50 operating hours or seasonally. Use SAE 30 detergent oil for most Chinese-made engines.
Spark Plugs
Clean annually, replace every 100 hours. Gap should be 0.76-0.84mm for optimal performance.
4. Battery Care (Electric Mowers)
Modern lithium-ion batteries from Chinese manufacturers require proper care:
- Store at 15-25°C (59-77°F)
 - Maintain 30-80% charge for storage
 - Allow cooling before recharging
 - Use only manufacturer-approved chargers
 
5. Common Problems & Solutions
Problem: Uneven Cutting
Solution: Check blade balance, deck leveling, and tire pressure. Chinese-manufactured decks often need adjustment after 80-100 hours.
Problem: Hard Starting
Solution: For gas mowers, check fuel line, spark plug, and carburetor. Many Chinese carburetors benefit from annual cleaning.
Professional Maintenance Tip
Have your mower serviced by a certified technician every 2-3 years. For China-made equipment, ensure they’re familiar with local manufacturing specifications.
