You’re out there, ready to tackle the overgrown lawn, but the pull string on your lawn mower snaps. Now, you’re facing a frustrating delay and a tangled mess of cord. Don’t worry, replacing a lawn mower pull string is a surprisingly simple task that you can handle yourself! This article will guide you through the process, step-by-step, equipping you with the knowledge to get your mower up and running again in no time. We’ll cover everything from identifying the right parts to the proper tools and techniques, ensuring a smooth and successful repair.
A Quick Overview
Changing the pull string on your lawn mower involves a few key steps. First, you’ll need to identify the right replacement cord and ensure you have the proper tools. Then, you’ll detach the old string, attaching the new one, and finally, reassemble the starter mechanism. With a little patience and these simple instructions, you’ll be back to mowing in no time.
Identifying the Right Parts
Before diving into the replacement process, it’s crucial to ensure you have the right parts. The pull string, also known as the starter rope, is a vital component of your lawn mower’s starting system. It connects to the recoil spring mechanism, responsible for spinning the engine’s crankshaft and igniting the combustion process.
What to Look For
- Starter Rope Length: The length of the pull string is essential. Measure the existing string from the end of the handle to the point where it disappears into the engine housing. Choose a replacement cord of the same length or slightly longer to allow for some slack.
- Starter Rope Material: Most pull strings are made of durable nylon, providing a good balance of strength and flexibility. However, some models might utilize specialized materials like Kevlar or other high-performance fibers. If you can’t determine the material of your original string, it’s best to err on the side of caution and choose a nylon replacement.
- Starter Rope Diameter: The diameter of the pull string is also crucial, ensuring a snug fit within the starter housing. Measure the diameter of the existing string or check the specifications for your specific lawn mower model.
Gathering Your Tools
For a successful pull string replacement, you’ll need a few basic tools:
Essential Tools
- Flathead Screwdriver: This will be used to remove the screws holding the starter housing in place.
- Pliers: Pliers will help you grip the pull string firmly for detachment and reattachment.
- Scissors or Utility Knife: These will come in handy for trimming excess string length.
The Replacement Process
Now that you have the right parts and tools, you can begin the replacement process:
Step 1: Disassembly
- Locate the starter housing: The starter housing is typically located on the side of the engine, often featuring a handle attached to the pull string.
- Remove the screws: Using your flathead screwdriver, carefully remove any screws holding the starter housing in place.
- Detach the starter housing: Gently pull the starter housing away from the engine, revealing the internal components.
Step 2: Replacing the Pull String
- Unhook the old string: Locate the point where the old pull string is attached to the starter mechanism. Using your pliers, carefully unhook the string from its attachment point.
- Remove the old string: Carefully remove the old pull string from the starter housing. If the string is frayed or broken, discard it.
- Attach the new string: Thread the new pull string through the starter mechanism, following the path of the old string. Make sure the new string is securely attached to the starter mechanism.
Step 3: Reassembly
- Reattach the starter housing: Carefully align the starter housing with the engine and gently push it back into place.
- Secure the screws: Use your flathead screwdriver to re-insert and tighten the screws that hold the starter housing in place.
- Trim the excess string: Use your scissors or utility knife to trim any excess string length, leaving a manageable loop at the handle end.
Troubleshooting and Tips
While replacing a pull string is a straightforward task, there might be a few hurdles to overcome. Here are some troubleshooting tips to keep in mind:
Common Problems and Solutions
- The new string is too short: If the new string is too short, you might need to purchase a longer replacement or consider a different length option.
- The string is tangled: If the string becomes tangled, carefully untangle it before proceeding with the reassembly process.
- The starter mechanism is jammed: If the starter mechanism is jammed, you might need to use a small screwdriver or pliers to carefully dislodge any obstructions.
Tips for Success
- Work in a clean area: Ensure you have a clean workspace to avoid any debris from falling into the starter mechanism.
- Be careful with the starter housing: Handle the starter housing with care to avoid damaging the delicate components.
- Test the new pull string: After reassembly, test the new pull string to ensure it operates smoothly and starts the engine.

Frequently Asked Questions
Q1: Why would I need to change the pull string on my lawnmower?
The pull string on your lawnmower is a crucial component that allows you to start the engine. Over time, the string can fray, break, or become stretched, making it difficult or impossible to pull the engine. A worn-out string can also cause the recoil spring to lose tension, leading to a sluggish or inconsistent start. Replacing the pull string ensures a smooth and reliable starting experience for your lawnmower.
Q2: What tools do I need to change the pull string?
Changing the pull string is a relatively straightforward process that requires basic tools. You’ll need a flathead screwdriver, a pair of pliers, and a new pull string that’s compatible with your lawnmower model. It’s also helpful to have a pair of safety glasses to protect your eyes from any potential debris. Make sure to unplug the spark plug before beginning the repair to prevent accidental starting.
Q3: How do I locate the pull string on my lawnmower?
The pull string is typically located on the top of the engine housing, near the recoil starter assembly. Look for a small handle or grip that’s attached to a rope or cable. The rope or cable will connect to the recoil spring and starter mechanism inside the housing. It’s important to identify the correct pull string and ensure it’s compatible with your lawnmower model before purchasing a replacement.
Q4: Can I reuse the old pull string after detaching it?
Reusing the old pull string is not recommended. Even if the old string appears intact, it may have internal damage or weakened fibers that can cause problems in the future. A fresh, high-quality pull string will ensure a smooth and reliable starting mechanism for your lawnmower.
Q5: What if I can’t find a replacement pull string for my lawnmower?
If you’re having trouble finding a specific replacement pull string for your lawnmower, you can consult a local lawnmower repair shop or contact the manufacturer directly.

It’s essential to use a compatible pull string to ensure proper functionality and prevent damage to the starting mechanism.
Q6: How do I know if the new pull string is installed correctly?
Once you’ve replaced the pull string, it’s crucial to check that it’s installed correctly and functioning properly. Make sure the string is securely attached to the recoil spring and the handle. When you pull the string, you should feel a smooth and consistent resistance. If the string feels loose or binds, you may need to adjust the installation or contact a professional for assistance.
