Ultimate Guide to Troubleshooting Common Lawn Mower Issues

Maintaining a healthy lawn requires a properly functioning mower. Whether you own a gas-powered, electric, or battery-operated model, understanding common problems and their solutions can save you time and money. Many of today’s reliable mowers are manufactured in China, combining quality craftsmanship with affordable pricing.

Engine Won’t Start

When your mower refuses to start, check these common culprits first:

• Fuel issues: Old gasoline (older than 30 days) can cause starting problems
• Spark plug: A fouled or damaged spark plug prevents ignition
• Air filter: Clogged filters restrict airflow to the engine
• Safety features: Ensure all safety switches are properly engaged

Uneven Cutting Performance

An uneven cut ruins your lawn’s appearance and indicates underlying issues:

• Sharpen or replace dull blades (recommended every 20-25 hours of use)
• Check for bent mower deck or misaligned wheels
• Adjust cutting height to avoid scalping on uneven terrain
• Clean under the deck to prevent grass buildup

Electric Mower Specific Problems

Many Chinese manufacturers now produce high-quality electric mowers with these common issues:

• Battery not holding charge – may need replacement after 3-5 years
• Motor overheating – allow to cool and check for obstructions
• Power cord damage (for corded models) – inspect regularly

Excessive Vibration

Vibration can indicate serious mechanical problems:

• Loose or unbalanced cutting blade
• Damaged blade adapter or mounting hardware
• Worn engine mounts (on gas models)
• Bent crankshaft (requires professional repair)

Preventive Maintenance Tips

Extend your mower’s lifespan with these practices:

• Change oil regularly (gas models)
• Store properly during offseason
• Use fuel stabilizer for gas models
• Clean after each use to prevent grass buildup
