A Brief Overview of Electric Lawn Mower Repairs
Electric lawn mowers, while generally simpler than their gasoline counterparts, can still develop problems. Common issues include battery problems, motor malfunctions, blade issues, and clogged cutting decks. Thankfully, most repairs can be tackled by a homeowner with basic tools and a bit of knowledge. This article will delve into identifying common problems, understanding safety precautions, and providing step-by-step instructions for fixing your electric mower.
Diagnosing the Problem: The First Step
Before you start taking apart your mower, it’s crucial to pinpoint the source of the problem. This can save you a lot of time and effort in the long run.
1. The Mower Won’t Start: A Checklist of Possibilities
- Battery Issue: The most common reason an electric mower won’t start is a dead battery. Check the battery charge level and recharge it if necessary. If the battery is fully charged, test its terminals for corrosion and clean them if required.
- Safety Switch: Electric mowers have safety switches that prevent accidental starting. Check the safety switch is engaged and not faulty.
- Power Cord: Make sure the power cord is properly plugged in and not damaged. Check for frayed wires or loose connections.
- Circuit Breaker: If you have an electric mower with a circuit breaker, check if it’s tripped. Reset the breaker if necessary.
- Motor Failure: If you’ve ruled out all other possibilities, the problem may be with the motor. In this case, you might need to consult a professional repair technician.
2. The Mower Runs but Won’t Cut: Exploring the Potential Causes
- Blade Issues: Examine the blade for dullness, damage, or misalignment. A dull blade will not cut effectively, and a damaged or misaligned blade can pose safety hazards.
- Clogged Cutting Deck: Grass, leaves, and other debris can build up in the cutting deck, hindering the blades. Clean the deck thoroughly to remove any obstructions.
- Motor Overload: If the motor is struggling to power the blades due to heavy grass or debris, it might be overloaded. Consider adjusting the cutting height or mowing in smaller sections.
Basic Repairs: Solving Common Problems
Now that you’ve diagnosed the issue, let’s explore some common repairs you can do yourself.
1. Replacing a Dead Battery
- Safety First: Always disconnect the mower from the power source before working on the battery.

- Install the New Battery: Align the new battery terminals with those in the compartment and gently secure it.
- Reconnect Power: Plug the mower back into the power source and test it.
2. Sharpening the Blades
- Safety Measures: Wear thick gloves and eye protection to avoid cuts.
- Disengage the Blade: Disconnect the mower from the power source and use a wrench to disengage the blade.
- Sharpen the Blades: Use a sharpening file or a sharpening stone to hone the cutting edges of the blades. Maintain a consistent angle and ensure both sides are sharpened equally.
- Clean and Lubricate: Clean the blade surface with a wire brush to remove debris and apply a light layer of lubricant.
- Reinstall and Test: Reinstall the sharpened blade, ensuring it’s properly aligned, and test the mower.
3. Cleaning the Cutting Deck
- Disconnect the Power: Unplug the mower before starting cleaning.
- Remove Debris: Use a brush, scraper, or vacuum to remove grass clippings, leaves, and other debris from the cutting deck.
