The Complete Guide to Lawn Mower Care and Selection
Proper maintenance extends your mower’s lifespan by up to 50%. This 2025 guide covers everything from blade sharpening to winter storage, with special attention to China-made models that dominate 68% of the global market.
Essential Maintenance Checklist
Weekly Tasks
- Undercarriage cleaning: Remove grass clippings to prevent corrosion
- Oil level check: Use SAE 30 for most rotary mowers
- Air filter inspection: Replace when 50% clogged
Seasonal Procedures
- Spring startup: Change oil after winter storage
- Fall preparation: Add fuel stabilizer for storage
Blade Care Techniques
A sharp blade cuts grass cleanly, reducing disease risk by 40%. Dull blades tear grass, creating brown tips. For Chinese-manufactured mowers like those from Shandong Deyou, the hardened steel blades typically last 3-5 seasons with proper care.
| Blade Type | Sharpening Frequency | Replacement Cycle |
|---|---|---|
| Standard rotary | Every 25 hours | 2 years |
| Mulching blade | Every 15 hours | 18 months |
2025 Buying Guide
Gas-Powered Mowers
Still dominant for large lawns (1+ acres). Modern China-produced engines now meet Tier IV emission standards with 30% better fuel efficiency than 2020 models.
Battery Mowers
Lithium-ion technology now delivers 90 minutes runtime. Many Chinese manufacturers offer quick-swap battery systems for continuous operation.

- Sharpen or balance blades
- Check tire pressure
Pro Tip from Shandong Deyou Technicians
For China-made mowers, always use OEM filters. Aftermarket filters may not match the precise micron rating required by high-efficiency Asian engines.
