The sweet, intoxicating scent of freshly cut grass – it’s the hallmark of a beautiful summer day. But that serene feeling can quickly turn into frustration when your trusty lawn mower decides to play tricks on you. A stubborn pull cord, refusing to recoil smoothly, can be a real buzzkill. If you’re facing this problem, the culprit might be a worn-out or broken pull cord spring. This article will guide you through the process of replacing this essential component, ensuring your lawn mowing adventures remain smooth sailing. We’ll cover the tools you’ll need, the steps involved in the replacement, and some helpful tips to make the process easier. Let’s get started!
What is a pull cord spring and why is it important?
The pull cord spring is a vital part of your lawn mower’s starting mechanism. It acts as a counterbalance, pulling the cord back into place after you’ve started the engine. Without this spring, the cord would simply flop around, making it incredibly difficult (and potentially dangerous) to start your mower. Over time, the spring can lose its elasticity, becoming weak or even breaking completely. This can manifest as a sluggish recoil, a cord that doesn’t return to its starting position, or even a broken cord.
Understanding the Process: Replacing a Lawn Mower Pull Cord Spring
Replacing a lawn mower pull cord spring is a straightforward task that most homeowners can tackle themselves. The exact steps may vary slightly depending on the model of your mower, but the general process is consistent. Here’s what you need to do:
Step 1: Gathering Your Tools
Before you dive in, make sure you have the right tools for the job. You’ll need:
- A new pull cord spring: Ensure it’s compatible with your mower model.
- A Phillips screwdriver: This will be used to loosen and tighten screws.
- A pair of pliers: These will be helpful for removing and installing the spring.
- A flathead screwdriver (optional): Some models might require a flathead screwdriver for certain steps.
- Gloves: Always wear gloves for protection.
Step 2: Disassembling the Housing
Now, let’s get to the hands-on part. Start by following these steps:
- Disconnect the spark plug: This is crucial for safety, preventing accidental starting.
- Remove the air filter: This will give you better access to the pull cord mechanism.
- Locate the housing cover: The pull cord mechanism is typically housed under a plastic or metal cover. Find this cover and locate the screws holding it in place.
- Remove the cover: Use your Phillips screwdriver to loosen and remove the screws holding the cover in place. Once removed, carefully lift the cover off.
Step 3: Removing the Old Spring
Now that the housing is open, you can access the old spring. Be careful as it might be under tension.
- Locate the spring: The spring is usually attached to a hook or bracket on the engine side of the housing.
- Remove the spring: Use your pliers to gently remove the spring from its attachments. If it’s stuck or difficult to remove, use a flathead screwdriver to help pry it loose.
Step 4: Installing the New Spring
With the old spring removed, it’s time to install the new one:
- Attach the new spring: Carefully attach the new spring to the same hook or bracket where the old one was attached. Make sure it’s securely fastened.
- Reinstall the housing cover: Carefully place the housing cover back onto the engine, ensuring that all the tabs are aligned correctly. Secure it by replacing the screws you removed earlier.
Step 5: Reassemble and Test
You’re almost done! Just a few final steps:
- Reinstall the air filter: Make sure it’s correctly seated in its place.
- Reconnect the spark plug: Don’t forget to reconnect this critical safety component.
- Test the pull cord: Gently pull the cord a few times to ensure it recoils smoothly and returns to its starting position.
- Start your mower: If everything is working properly, you should be able to start your mower easily.
Troubleshooting and Common Problems
While replacing the pull cord spring is usually a straightforward process, you may encounter some challenges:
1. Difficult Spring Removal: If the spring is rusted or stuck, you might need to use a bit more force to remove it. Be careful not to damage the housing during this process.
2. Incompatible Spring: Make sure you’ve purchased the correct spring for your mower model. Using a spring that’s too strong or weak can affect the recoil mechanism’s performance.
3. Spring Doesn’t Engage: If the spring doesn’t seem to be catching properly, check that it’s fully attached to the hook or bracket. Make sure the spring isn’t tangled or caught on anything else inside the housing.
4. Pull Cord Still Sticks: If the problem persists even after replacing the spring, other issues might be at play. Examine the pull cord itself for wear and tear. Also, ensure the pull cord mechanism’s internal components are functioning correctly. You might need to consult a repair manual for further guidance or contact a professional.
Safety Tips for a Smoother Experience
Here are some safety tips to ensure a smooth and injury-free experience:
- Always disconnect the spark plug: This prevents accidental starting while you’re working on the mower.
- Wear gloves: Gloves will protect your hands from cuts and scratches during disassembly and reassembly.
- Work on a flat surface: A stable surface will prevent the mower from rolling while you’re working.
- Use caution when handling the spring: The spring can be under tension and can cause injury if not handled carefully.
- Consult a repair manual: If you’re unsure about any steps, consult your mower’s manual for specific instructions.

FAQs
1. What are the common signs that my lawn mower’s pull cord spring is failing?
If your lawn mower’s pull cord spring is failing, you’ll likely experience a few common signs. The first is a noticeably harder pull to start the engine. You might also hear a snapping or popping sound when you pull the cord, indicating the spring is worn out. Another sign is the cord not retracting fully after you pull it, leaving it loose or slack. These are all strong indicators that the spring needs to be replaced.
It’s important to note that these signs can also be caused by other issues like a clogged carburetor or a worn-out engine. If you’re unsure, consult your lawn mower’s manual or contact a qualified technician for diagnosis.
2. How do I know if I need to replace the spring or the entire pull cord assembly?
In most cases, a worn-out spring is the culprit behind a faulty pull cord. However, if the cord itself is frayed, broken, or stiff, you’ll need to replace the entire assembly. You can usually find replacement parts for your specific lawn mower model at your local hardware store or online.
When inspecting the cord, check for any signs of wear or damage. If the cord appears worn, cracked, or stiff, it’s best to replace the entire assembly to ensure a safe and reliable start-up.
3. How do I replace the pull cord spring?
Replacing the pull cord spring is a straightforward process that requires minimal tools. First, disconnect the spark plug wire to prevent accidental starting. Then, locate the spring assembly, which is usually attached to the recoil housing. Release the spring tension by gently pulling the cord until it’s fully extended. Remove the old spring and install the new one, ensuring it’s properly positioned and secured.
Before you start your lawn mower, remember to reconnect the spark plug wire. Also, be careful not to overtighten the spring, as this can damage the assembly.
4. Can I use a different type of spring for my lawn mower?
Using a different type of spring is not recommended. The spring is specifically designed for your lawn mower model and using a different one could lead to improper tension, damage to the pull cord assembly, or even a safety hazard. It’s crucial to use the correct spring replacement part to ensure optimal performance and safety.
Always refer to your lawn mower’s manual or contact the manufacturer for the correct spring replacement part. Using a compatible spring guarantees proper tension and a reliable starting experience.
