In this article, we’ll cover the common issues that can arise with your lawn mower pull cord, identify the tools you’ll need, and provide step-by-step instructions on how to replace the cord and get your mower running smoothly again. Let’s dive in!
Understanding Your Lawn Mower Pull Cord: A Quick Overview
The pull cord is a vital part of your lawn mower’s starting system. It’s the physical link between you and the engine, transferring the energy of your pull to the starter mechanism, ultimately turning the engine over. The cord itself is usually made of nylon or rope, and it runs through a series of components, including a spring, a recoil housing, and a starter pawl.
Common issues with pull cords can include:
- Snapped or frayed cord: This is the most frequent problem, caused by wear and tear from repeated use.
- Stuck or damaged recoil spring: The spring can become stuck or lose its elasticity, preventing the cord from retracting properly.
- Broken starter pawl: This small, toothed component engages with the engine’s flywheel to initiate rotation. A broken or worn pawl will prevent the engine from turning.
Tools You’ll Need for the Job
Before you begin, gather the following tools:
- New pull cord: You’ll find replacement cords at most hardware stores, often labelled with the make and model of your lawn mower.
- Philips screwdriver: Used to remove and re-attach screws.
- Flathead screwdriver: For prying open components and removing clips.
- Pliers: To grip and pull the old cord, and to secure the new cord.
- Safety glasses: To protect your eyes from potential debris.
- Work gloves: To provide grip and protect your hands.
Step-by-Step Guide to Replacing Your Lawn Mower Pull Cord
1. Disconnect the Spark Plug
- Safety First: This step is crucial to preventing accidental starting. Locate the spark plug on your engine, usually a black, cylindrical component with a wire connected to it.
- Disconnect: Carefully remove the spark plug wire by pulling it off the spark plug. Set the wire aside to prevent it from accidentally coming into contact with the plug.
2. Remove the Recoil Housing Cover
- Locate the Cover: The recoil housing is the plastic or metal casing that encloses the pull cord mechanism. It’s usually located near the top of the engine.
- Remove Screws: Use a Philips screwdriver to loosen and remove the screws holding the cover in place. The number of screws will vary depending on your mower model.
- Remove the Cover: Once the screws are removed, gently pry off the cover. It may be held in place by clips or tabs.
3. Inspect and Replace the Pull Cord
- Inspect the Old Cord: Carefully examine the old pull cord for any signs of wear, fraying, or breakage.
- Remove the Old Cord: Most lawnmower pull cords are held in place by a knot or a small clip. You’ll need to carefully work the cord free from the recoil mechanism.
- Install the New Cord: Thread the new pull cord through the recoil mechanism, following the path of the old cord. Be sure to orient the cord so that it wraps correctly around the spring.
- Secure the Cord: Once the new cord is threaded, secure it using the knot, clip, or other method used by the old cord.
4. Reassemble the Recoil Housing
- Replace the Cover: Align the recoil housing cover with the housing and carefully reattach it.
- Replace the Screws: Tighten the screws holding the cover in place, ensuring a secure fit.
- Reconnect the Spark Plug: Reconnect the spark plug wire to the spark plug, ensuring a snug connection.
5. Test the Pull Cord
- First Pull: Pull the cord slowly a few times to ensure it’s moving freely and retracting correctly.
- Engine Test: With the spark plug wire securely connected, gently pull the cord to start the engine. If the engine starts without any issues, you’ve successfully replaced the pull cord.
Troubleshooting Common Issues:
- Cord Won’t Retract: If the cord fails to retract after replacing it, inspect the spring for damage or binding. You may need to replace the spring if it’s broken or no longer retracting properly.
- Engine Doesn’t Start: If the engine doesn’t start after replacing the cord, double-check the spark plug connection, and ensure the engine is getting fuel. You may need to troubleshoot other engine-related issues.
Safety Tips for Replacing Your Lawn Mower Pull Cord:
- Always disconnect the spark plug wire before working on the engine: This will prevent accidental starting.
- Wear safety glasses and gloves: This protects you from potential debris and injury.
- Use the right tools: Using the correct tools will make the job easier and safer.
- Never attempt to modify or repair the recoil mechanism if you are not familiar with the process: Improper modifications can lead to serious injury.
- If you are unsure about any aspect of the repair, consult a qualified technician.

FAQs
What is a pull cord and why does it break?
The pull cord is a long, braided rope attached to the engine of your lawnmower. When you pull it, it engages the engine’s starter, allowing you to start the machine. The pull cord can break for several reasons, such as wear and tear from frequent use, being stretched too far, or getting snagged on something.
What are the steps involved in fixing a pull cord?
Fixing a broken pull cord is a simple repair that can be done in a few steps. First, you’ll need to detach the old cord from the starter. Then, you’ll need to feed the new cord through the starter and reattach it securely. Finally, you’ll need to attach the end of the new cord to the handle. If the cord is frayed, you’ll need to replace it with a new one.
What tools do I need to fix a pull cord?
To fix a pull cord, you’ll only need a few basic tools. You’ll need a Phillips screwdriver to remove the screws holding the starter cover in place. You’ll also need a pair of pliers to help you feed the new cord through the starter. If the cord is frayed, you’ll also need a new pull cord.
How do I know if I need to replace the pull cord?
If the pull cord is frayed, broken, or worn out, you’ll need to replace it. If the cord is still intact but feels weak or stretched, you may need to replace it as well. If you can’t start your lawnmower and you’ve checked other potential problems, a broken pull cord may be the culprit.
What kind of pull cord should I use?
It’s important to use a pull cord that is compatible with your lawnmower. The best way to find the right cord is to consult your owner’s manual or to contact the manufacturer. You can also find compatible cords at most hardware stores.
Can I use a different type of rope as a replacement?
You can try using a different type of rope as a replacement, but it’s not recommended. A standard pull cord is designed to withstand the forces involved in starting a lawnmower engine. Using a different type of rope could lead to the cord breaking prematurely or even causing damage to the starter.
What other tips should I consider?
To prevent future pull cord issues, be sure to properly store your lawnmower when not in use. Also, avoid pulling the cord too forcefully. If the engine doesn’t start on the first pull, try again a few times before pulling harder. Be mindful of any obstructions that could snag the pull cord.
