A Short Overview of Replacing a Lawn Mower Cord
Replacing a lawn mower cord is a relatively straightforward process that involves disconnecting the old cord, identifying the correct replacement, and securely connecting the new cord to the mower’s electrical components. This guide provides detailed instructions, safety precautions, and troubleshooting tips to ensure a smooth and successful repair.
Understanding Your Lawn Mower and Cord
Before you start tearing into your lawnmower, it’s essential to understand the type of cord you need and the basic components of your mower’s electrical system.
Identifying the Correct Cord Type
- Cord Length and Gauge: The replacement cord must match the length and gauge of the original cord. Measure the old cord for length and look for the gauge printed on the wire insulation. A thicker gauge, like 12 gauge, handles more power.
- Cord Type: Different types of cords are designed for different purposes. Ensure you choose a cord rated for outdoor use, moisture resistance, and the wattage of your mower. Look for the cord’s specifications on its label.
- Plug Type: The plug on the new cord must match the plug on the mower’s power outlet.
- Wire Insulation: The insulation on the new cord should match the material and color coding of the original cord.
Understanding Lawn Mower Electrical Components
- Power Switch: The power switch is usually located on the handle and controls the flow of electricity to the motor.
- Motor: The motor is the heart of your lawnmower, converting electrical energy into mechanical energy to drive the blades.
- Electrical Harness: The electrical harness is a bundle of wires that connect the power switch, motor, and other components.
Gathering Your Tools and Materials
Before you begin, gather the following tools and materials:
- Replacement cord: Ensure you have the correct length, gauge, type, and plug.
- Wire strippers: To remove insulation from the cord’s wires.
- Wire crimping tool: For attaching terminals to the cord’s wires.
- Wire connectors: To connect the new cord’s wires to the existing harness.
- Screwdriver: To loosen and tighten screws during the process.
- Electrical tape: For insulating exposed wire ends.
- Gloves: To protect your hands from potential electrical shocks.
Preparing Your Lawn Mower for the Replacement

- Attach Terminals: Use the wire crimping tool to attach terminals to the stripped ends of the new cord’s wires. The terminals will match the connectors on your lawnmower.
Connecting the New Cord
- Connect the New Cord to the Power Switch: Connect the new cord’s wires to the power switch using the appropriate terminals and connectors.
- Connect the New Cord to the Electrical Harness: Connect the remaining wires of the new cord to the corresponding wires in the electrical harness using the appropriate terminals and connectors.
- Secure the Connections: Ensure all connections are secure and properly insulated to prevent electrical shorts or malfunctions.
Testing and Finishing Touches
Once you’ve connected the new cord, it’s time to test your work and finish the repair.
Testing the Mower
- Reconnect the Spark Plug Wire: Make sure the spark plug wire is properly connected.
- Plug in the Mower: Reconnect the power source to the mower.
- Turn on the Power Switch: Turn on the power switch to test the motor.
- Check for Malfunctions: If the motor doesn’t run, or there are sparks or other issues, immediately disconnect the power source and check your connections.
Completing the Repair
- Secure the Electrical Harness: Make sure the electrical harness is properly secured and all components are in place.
- Replace Covers and Screws: Replace any covers or screws that were removed to access the electrical harness.
- Double-Check Connections: Ensure all connections are secure and insulated to prevent electrical hazards.
- Clean and Inspect: Clean any dirt or debris from the area around the electrical components.
Troubleshooting Tips

Frequently Asked Questions
What tools do I need to replace a lawn mower cord?
You will need a few basic tools to replace your lawn mower cord. You’ll need a wire stripper, a pair of pliers, a screwdriver, and a wire connector. Some lawn mowers also have a cord lock that you will need to remove. The wire stripper is used to expose the wires in the cord, while the pliers are used to crimp the connector onto the wires. A screwdriver is used to remove the screws that hold the cord in place. Lastly, the wire connector is used to connect the new cord to the lawn mower’s electrical system.
You may also need electrical tape or heat shrink tubing to insulate the wires after you have stripped them. If you are unsure about any of these tools, it is best to consult with a qualified technician before attempting to replace the cord yourself.
How do I disconnect the old cord from the lawn mower?
To disconnect the old cord from the lawn mower, you will first need to locate the cord’s connection point. This is usually located on the bottom or side of the mower. Once you’ve found it, carefully remove any screws or clips that are holding the cord in place. After you have removed the old cord, you can then start preparing the new cord for installation.
Before removing the old cord, ensure the power switch is off and the mower is unplugged from the power outlet. You should also be careful not to cut or damage the wires in the old cord, as this could make it difficult to install the new cord.
How do I connect the new cord to the lawn mower?
To connect the new cord to the lawn mower, you will first need to strip the insulation off the ends of the wires.
