Why Electric Lawn Mowers Need Maintenance

Electric lawn mowers might seem maintenance-free compared to their gas-powered counterparts, but they still need care to function well. Here are the key reasons why:

Maintenance Essentials

Regular maintenance is crucial for any machine, and electric lawn mowers are no exception. Even though they don’t need oil changes or spark plug replacements, they do require tasks like cleaning, lubrication, and inspections to keep them running smoothly.


Proper maintenance can significantly extend the life of your electric mower. José R. Mendoza, a home improvement expert, says, “Lawn mowers typically last five to ten years, depending on the model, use, and maintenance.” Regular care ensures that your investment lasts as long as possible.


A well-maintained mower performs better. Dirt and grass clippings can clog the undercarriage and vents, reducing efficiency. Sharpening the blade and keeping the battery in good condition ensure that your mower cuts grass effectively and runs longer on a single charge.


Safety is another critical reason for regular maintenance. Loose bolts, worn-out blades, and clogged vents can be hazardous. Laura Daily, a consumer advocate, notes, “Check all bolts and fasteners. Grass cutting causes a lot of vibrations. These vibrations can sometimes cause screws, fasteners or bolts to come loose.” Tightening these parts helps prevent accidents.

In summary, do electric lawn mowers need maintenance? Absolutely. Regular upkeep ensures longevity, optimal performance, and safety. Let’s move on to the specific tasks you should perform to keep your mower in top shape.

Regular Maintenance Tasks

Cleaning Your Electric Lawn Mower

Keeping your electric lawn mower clean is crucial for its performance and longevity. Start with the undercarriage—the part where the blade is housed. Grass clippings can build up here and affect the mower’s efficiency. Use a plastic brush to scrape off dried clippings. Be careful not to use water, as it can cause corrosion in the motor.

Next, focus on the motor vents. Dust and debris can clog these vents, causing the motor to overheat. Use an air blower to clear out any particles. This simple step can extend the life of your mower.

Lubricating Moving Parts

Lubrication is key to keeping the moving parts of your mower in good condition. A light squirt of WD-40 on the wheels and other metal parts like the blade can make a big difference. This prevents rust and ensures smooth operation.

Be careful not to overdo it. Too much lubricant can attract dust and debris, causing more harm than good.

Inspecting and Tightening Parts

Grass cutting causes a lot of vibrations, which can loosen bolts, screws, and fasteners. Regularly check these parts and tighten them as needed. Laura Daily, a consumer advocate, emphasizes, “Check all bolts and fasteners. Grass cutting causes a lot of vibrations. These vibrations can sometimes cause screws, fasteners or bolts to come loose.”

Battery Maintenance

Battery care is vital for electric lawn mowers. Always inspect the battery for cracks or other issues before storing it. Batteries should be stored fully charged and kept in a warm, dry place. Extreme temperatures can ruin the battery.

Charging is also important. Most batteries have a power level indicator. If the charge drops, top it up to maintain its health. Regular checks every six weeks during the off-season can ensure your battery is ready when you need it.

Seasonal Maintenance Tips

End-of-Season Tasks

As grass-cutting season winds down, it’s crucial to prepare your electric lawn mower for winter storage. Here’s a simple checklist:

  1. Clean the Undercarriage: Grass clippings can cause rust and damage. Use a brush to scrape off any dried clippings from the mower’s undercarriage. Avoid using a hose or pressure washer on electric mowers to prevent water from getting into the motor.

  2. Lubricate Moving Parts: Apply a light coat of lubricant, like WD-40, on the wheels and blade. This prevents rust and keeps parts moving smoothly. A gentle squirt is enough—don’t overdo it.

  3. Inspect and Tighten Parts: Vibration from mowing can loosen bolts, screws, and fasteners. Check and tighten everything to ensure your mower is safe and ready for the next season.

  4. Battery Care: Fully charge your batteries before storing them. Inspect the battery housing for cracks and store them in a warm place. Avoid freezing temperatures to maintain battery life.

Proper Storage Techniques

Storing your electric lawn mower correctly can extend its lifespan and keep it in good working condition. Here are some tips:

  1. Indoor Storage: Keep your mower in a dry, indoor space like a garage or shed. Moisture can damage the motor and other components, leading to costly repairs.

  2. Temperature Control: Avoid extreme temperatures. Batteries and other electrical components perform best when stored in moderate conditions. If you live in a cold climate, bring the batteries indoors.

  3. Moisture Protection: Use a cover to protect your mower from dust and moisture. This keeps both the external and internal parts in good condition.

Sharpening the Blade

A sharp blade is essential for a clean cut and healthy lawn. Here’s how to sharpen your mower blade:

  1. Removal: Disconnect the spark plug and remove the blade. This ensures safety while you work.

  2. Sharpening Tools: Use a bench grinder for the best edge. If you don’t have one, a special hand tool designed for sharpening lawn mower blades will work.

  3. Rust Prevention: After sharpening, apply a thin coat of WD-40 to the blade. This prevents rust from forming during storage.

  4. Reinstallation: Reattach the blade securely. Double-check that all bolts are tight to avoid any issues when you start mowing again.

By following these seasonal maintenance tips, you’ll keep your electric lawn mower in peak condition year-round. Proper end-of-season care, correct storage, and regular blade sharpening ensure your mower is always ready for action when spring arrives.

Common Issues and Troubleshooting

Even with regular maintenance, you might encounter some common issues with your electric lawn mower. Here’s how to troubleshoot and fix them.

Battery Problems

Charging Issues: If your battery isn’t charging properly, first check the charger and the power source. Ensure the connections are secure. If the problem persists, the battery might be faulty and need replacing.

Storage Tips: Always store your battery in a warm, dry place. Cold temperatures can damage the battery, reducing its lifespan. Check the battery charge every six weeks during storage and recharge if necessary.

Replacement: If your battery loses its charge quickly or doesn’t hold a charge at all, it might be time for a replacement. Inspect the battery housing for cracks or other damage, which can also indicate the need for a new battery.

Motor Issues

Cleaning: Grass clippings and debris can clog the motor vents, leading to overheating. Use an air compressor or blower to clean out these areas regularly.

Debris Removal: Ensure there’s no debris stuck in the undercarriage or around the blades. This can cause the motor to work harder than necessary, reducing its efficiency.

Professional Servicing: If the motor still has issues after cleaning, it might need professional servicing. Contact the manufacturer or an authorized dealer for assistance.

Unusual Vibrations

Inspection: Unusual vibrations often indicate loose parts. Inspect all bolts, screws, and fasteners. Tighten anything that’s come loose due to the mower’s vibrations during use.
