Getting Started: Tools and Materials
Before diving into the replacement process, gather the following tools and materials:
- New pull cord: Make sure to purchase a cord specifically designed for your lawn mower model.
- Phillips screwdriver: This will be used to remove screws.
- Flat-head screwdriver: A flat-head might be needed to pry open certain parts or remove clips.

Step-by-Step Guide: Replacing the Pull Cord
1. Disconnect the Spark Plug
Safety first! Before you start dismantling your lawnmower, it’s crucial to disconnect the spark plug to prevent accidental starting. Locate the spark plug, usually near the engine cylinder, and unscrew it using a spark plug wrench.
2. Disassemble the Recoil Starter Housing
To access the pull cord, you’ll need to dismantle the recoil starter housing. This process varies slightly depending on the mower model, but the general steps are as follows:
- Remove the cover: Locate the cover that protects the recoil starter. It might be held in place by screws or clips. Carefully remove these fasteners and lift off the cover.
- Detach the housing: The recoil starter housing is usually connected to the engine by screws or a spring-loaded pin. Remove these fasteners to detach the housing.
3. Remove the Old Pull Cord
Once the housing is removed, the old pull cord should be visible. Inspect the cord and note how it’s attached to the recoil starter. You’ll need to replicate this attachment when installing the new cord.
- Locate the attachment: The old cord will likely be attached to the recoil starter with a small loop that fits into a hook or a clip.
- Detach the cord: Carefully remove the cord from its attachment point.
4. Install the New Pull Cord
With the old cord removed, you’re ready to install the new one.
- Thread the cord: Thread the new pull cord through the recoil starter, following the same path as the old cord.
- Attach the cord: Secure the new cord to the recoil starter using the same method as the old cord. This might involve attaching it to a hook, fitting it into a clip, or tying it to a specific point on the starter.
- Check for tension: Ensure the cord is properly tensioned. A good pull cord should have a slight resistance when pulled.
5. Reassemble the Housing
Now that the new cord is installed, you can reassemble the recoil starter housing.
- Attach the housing: Reattach the housing to the engine, securing it with the screws or pins you removed earlier.
- Reinstall the cover: Replace the cover over the recoil starter and secure it with the screws or clips.
6. Reconnect the Spark Plug
Finally, reconnect the spark plug, ensuring it’s securely tightened.
Troubleshooting Tips
If you’re experiencing issues with the new pull cord, here are some troubleshooting tips:
- Check for proper tension: The pull cord should have a slight tension, allowing for a smooth pull. If it feels too loose or too tight, adjust the cord’s attachment point.
- Inspect the recoil starter: A malfunctioning recoil starter can prevent the pull cord from operating correctly. Check for any damage or wear and tear, and consider replacing it if necessary.
- Look for obstacles: Ensure there are no obstructions blocking the pull cord’s movement.
- Consult your owner’s manual: Your lawnmower’s manual contains specific instructions for replacing the pull cord. Refer to it for detailed guidance tailored to your model.
Maintenance Tips
Here are some tips for keeping your lawnmower’s pull cord in good condition:
- Regular inspection: Inspect the pull cord for wear and tear. Replace it if you notice any fraying or damage.
- Lubrication: Lubricate the recoil starter mechanism with a light oil periodically. This will help prevent friction and ensure smooth operation.
- Avoid excessive force: Don’t pull the cord with excessive force, as this can damage the recoil starter mechanism.

FAQs
1. Why do I need to replace the pull cord on my lawn mower?
A worn or broken pull cord can make it difficult or impossible to start your lawn mower. The cord can fray, break, or become stretched, hindering its ability to engage the starter mechanism. Replacing the cord is a relatively simple task that can save you from frustration and potentially expensive repairs.
It is best to replace the cord as soon as it shows signs of wear. A frayed cord can easily break, leaving you stranded and unable to mow your lawn. Replacing it proactively ensures that your lawn mower remains functional and ready to tackle your yard work.
2. What tools do I need to replace the pull cord?
You will only need a few basic tools to replace the pull cord on your lawn mower. These include a flathead screwdriver, pliers, and a new pull cord. You may also need a pair of wire cutters or a utility knife if the old cord is difficult to remove.
The specific tools you require may vary depending on the make and model of your lawn mower. Always consult your owner’s manual for detailed instructions and recommended tools for your specific mower.
3. How do I remove the old pull cord?
To remove the old pull cord, you will need to access the starter housing. This usually involves removing a cover or panel on the side of the mower deck. Once you have access to the starter housing, you can identify the pull cord mechanism.
Typically, the cord is attached to a spring-loaded recoil assembly. You will need to carefully detach the cord from the assembly, often by releasing a clip or unthreading a nut.
4. How do I install the new pull cord?
Installing the new pull cord is essentially the reverse of the removal process. First, thread the new cord through the recoil assembly, ensuring it is properly seated. Then, reattach the cord to the spring-loaded mechanism using the same method used for the old cord.
Before securing the cord, make sure the spring is properly tensioned. This ensures that the cord recoils smoothly and effectively engages the starter mechanism.
5. What are some tips for replacing the pull cord?
When replacing the pull cord, it’s important to work carefully and avoid damaging the starter assembly. Be gentle when removing the old cord and ensure the new cord is properly installed. Make sure to test the cord after installation to confirm it is functioning correctly.
Additionally, it’s recommended to use a high-quality pull cord specifically designed for your lawn mower. This ensures compatibility and long-lasting performance.
6. Can I replace the pull cord myself, or should I take it to a mechanic?
Replacing the pull cord is a relatively straightforward task that most homeowners can handle themselves. However, if you are unfamiliar with mechanical repairs or feel uncomfortable working with tools, it’s best to take your lawn mower to a qualified mechanic.
A mechanic can quickly and efficiently replace the cord while ensuring that the starter assembly is properly adjusted and functioning correctly.
7. How often should I replace the pull cord?
While there is no set schedule for replacing the pull cord, it is recommended to inspect it regularly for signs of wear and tear. If you notice any fraying, stretching, or damage, it is time to replace the cord. This proactive approach ensures that your lawn mower continues to operate smoothly and avoids potential issues during your mowing sessions.
