The sweet hum of an electric lawn mower is music to the ears of any homeowner looking for a quick and quiet way to maintain their yard. But what happens when that hum turns into a sputtering cough or a complete silence? Don’t despair! While electric lawn mowers may seem complex, many common issues can be fixed with a little bit of know-how and some basic tools. This comprehensive guide will walk you through troubleshooting and fixing your electric mower, from identifying the problem to replacing parts, so you can get back to enjoying a pristine lawn.
A Quick Overview
Electric lawn mowers, though generally reliable, can experience a range of problems. Common culprits include dead batteries, faulty cords, clogged blades, and issues with the motor. This article will cover the most frequent problems and provide detailed instructions on how to diagnose and fix them. We will also explore how to maintain your mower to prevent issues in the first place.
Identifying the Problem: A Troubleshooting Guide
The first step in fixing your electric lawn mower is pinpointing the problem. Ask yourself these questions:
- Does the mower turn on at all? If not, you might have a battery issue, a faulty cord, or a problem with the motor.
- Does the mower run but not cut grass effectively? This could indicate a clogged blade, a dull blade, or a problem with the motor.
- Does the mower make strange noises? Grinding, clicking, or humming noises can point to a variety of issues, from a damaged blade to a faulty motor.
Once you’ve identified the problem, you can move on to the specific troubleshooting steps outlined in the following sections.
Battery Issues: The Power Source
Electric lawn mowers powered by rechargeable batteries rely on a healthy battery to function properly. If your mower isn’t turning on, the first place to look is the battery.
Checking the Battery
- Charge the Battery: Start by plugging your battery into the charger and letting it charge for the recommended amount of time. Most batteries take several hours to fully charge.
- Check the Battery Connections: Ensure the battery is securely connected to the mower. Examine the terminals for corrosion or loose connections, and clean them if necessary.
- Test the Battery: If the battery still doesn’t seem to hold a charge, you may need to replace it. Look for compatible batteries from the manufacturer or a reputable online retailer.
Cord Problems: The Lifeline
Cordless electric lawn mowers are convenient, but corded mowers offer consistent power. If you have a corded mower that isn’t working, the problem could be with the cord itself.
Inspecting the Cord
- Check for Damage: Visually inspect the cord for any signs of damage, such as cuts, frays, or exposed wires. If you find any damage, replace the cord immediately.
- Test the Outlet: Plug the mower into a different outlet to ensure the original outlet is working. If the mower works in a different outlet, the original outlet may be faulty.
- Check the Cord Connection: Make sure the cord is securely connected to the mower and the outlet.
Blade Problems: The Cutting Edge
A dull or clogged blade can significantly impact your mower’s cutting performance.
Sharpening and Cleaning the Blade
- Remove the Blade: Disconnect the mower from the power source and use a wrench to remove the blade.
- Sharpen the Blade: Use a file or sharpening stone to sharpen the blade. Ensure a consistent sharpening angle along the entire cutting edge.
- Clean the Blade: Wipe the blade clean with a rag to remove any debris or grass clippings.
- Reinstall the Blade: Reinstall the blade, making sure it’s properly secured and aligned.
Motor Issues: The Heart of the Mower
The electric motor is the heart of your lawn mower. If the motor isn’t working, your mower will not operate.
Diagnosing Motor Issues
- Check the Motor Connection: Ensure the motor is properly connected to the power source or battery.
- Check for Obstructions: Inspect the motor for any obstructions or debris that could be preventing it from running.
- Check the Brushes: In some motors, carbon brushes wear down over time. Check the brushes and replace them if they are worn.
- Test the Motor: If the motor still isn’t working, you may need to replace it.
Maintaining Your Electric Mower: Prolonging its Life
Preventive maintenance can extend the life of your electric lawn mower and prevent future issues.
Regular Maintenance Tasks
- Clean the Mower: After each use, wipe down the mower with a damp cloth to remove any dirt or debris.
- Check the Blade: Regularly inspect the blade for signs of dullness or damage. Sharpen or replace the blade as needed.
- Clean the Motor: Periodically clean the motor to prevent dirt or debris from accumulating.
- Store the Mower Properly: Store the mower in a dry, clean place when not in use.
Additional Tips for Troubleshooting
- Read the Owner’s Manual: Consult your mower’s owner’s manual for specific instructions and troubleshooting tips.
- Seek Professional Help: If you are unable to diagnose or fix the problem yourself, it is best to seek professional help from a qualified repair technician.

FAQs
Why is my electric lawn mower not starting?
There are a few reasons why your electric lawn mower might not start. First, check to make sure the mower is plugged in and that the outlet is working. You should also check the circuit breaker to see if it has tripped. If the circuit breaker is tripped, reset it and try starting the mower again.

In this case, you’ll need to take the mower to a qualified repair shop to have it inspected and repaired.
How often should I replace the blade on my electric lawn mower?
The frequency of blade replacement on an electric lawn mower depends on usage and the type of grass you’re mowing. However, a general guideline is to replace the blade every 1-2 seasons. Signs of a worn-out blade include dulling, chipping, or uneven cutting. It’s crucial to replace a worn blade as it can affect the quality of your cut and potentially damage the mower.
Can I use a regular extension cord with my electric lawn mower?
Using a regular extension cord with your electric lawn mower can be dangerous and potentially damage your mower. The cord might not be able to handle the power requirements of the mower, leading to overheating or even a fire.
