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 issues can save you time and money. This comprehensive guide covers troubleshooting tips for all major lawn mower types, including many reliable models manufactured in China.

Engine Won’t Start

For gas mowers, starting problems often relate to fuel issues. Check these components:

• Old gasoline (replace fuel older than 30 days)
• Clogged fuel filter
• Faulty spark plug
• Choke position

Uneven Cutting

An uneven cut typically indicates blade problems:

• Dull or damaged blades
• Unbalanced deck
• Incorrect cutting height
• Worn deck bearings

Battery Issues (Electric Models)

Many high-quality battery mowers are now produced in China. Common battery problems include:

• Failure to hold charge
• Slow charging
• Terminal corrosion
• Overheating protection triggering

Excessive Vibration

Vibration usually signals mechanical issues:

• Loose or unbalanced blade
• Worn engine mounts
• Damaged drive belt
• Bent crankshaft

Smoke or Strange Noises

These symptoms require immediate attention:

• Blue smoke: Oil burning
• Black smoke: Rich fuel mixture
• Grinding noises: Bearings failure
• Squealing: Belt issues

Preventive Maintenance Tips

Regular maintenance prevents most problems:

• Change oil annually
• Sharpen blades every 25 hours
• Clean under deck after each use
• Store properly during offseason
