Tired of battling your lawn mower’s balky pull cord? A broken or worn-out pull string is a common issue, but it’s a simple fix that can save you a trip to the repair shop. This article will walk you through the process of replacing your lawn mower’s pull string, step-by-step. We’ll cover everything from identifying the right replacement string to ensuring a smooth, reliable starting experience for your mower.
A Quick Overview:
Replacing a pull string is a straightforward process involving removing the old string, threading a new one, and reassembling the starter assembly. The specific steps may vary slightly depending on your mower’s model, but the fundamental principles remain the same.
Identifying the Right Pull String
Before you begin, it’s essential to identify the correct replacement pull string for your lawn mower. The string’s length, thickness, and material are crucial for ensuring proper operation.
Determining the Correct Length
The pull string’s length is crucial for maintaining proper tension and ensuring a smooth pull. The string should be long enough to extend from the recoil housing to the handle without excessive slack or stretching.
Finding the Right Thickness and Material
The thickness of the pull string influences its durability and the force required to pull it. A thicker string is more durable but may require more effort to start the mower. Thinner strings are lighter and easier to pull but may not last as long.
The material of the pull string is also important. Most pull strings are made of nylon or polyester, which offer good durability and flexibility.
Sourcing a Replacement Pull String
You can find replacement pull strings at most hardware stores, home improvement centers, and online retailers. When purchasing, bring your mower’s model number to ensure you get the correct string.
Tools Needed for the Job
Before you start, gather the following tools:
- Phillips head screwdriver: This is used to remove the screws holding the recoil housing in place.
- Needle-nose pliers: These are helpful for maneuvering the pull string and securing the ends.
- Scissors or a utility knife: For cutting the pull string to the correct length.
- Replacement pull string: Make sure to have the correct length, thickness, and material.
Replacing the Pull String – Step by Step
Now that you have the right tools and a new pull string, you can get started with the replacement process.
Step 1: Disassemble the Starter Housing
- Locate the starter housing: This is usually a cylindrical unit located on top of the engine near the pull handle.
- Remove the screws: Using your Phillips head screwdriver, remove the screws that hold the recoil housing in place.
- Remove the housing: Carefully lift the recoil housing off the engine.
Step 2: Remove the Old Pull String
- Locate the pull string attachment points: The pull string is typically attached to the recoil spring and the handle assembly.
- Release the string from the handle: The pull string is usually secured to the handle using a small metal clip or a screw.
- Remove the string from the spring: The string may be attached to the recoil spring with a small metal loop or a knot. Carefully release the string from the spring.
Step 3: Install the New Pull String
- Thread the new pull string: Thread the new pull string through the spring, ensuring it’s correctly positioned in the grooves or loops.
- Attach the string to the handle: Secure the new pull string to the handle using the same method as the old one.
- Secure the string to the spring: Make sure the new string is properly attached to the recoil spring, using the same method as the old string.
Step 4: Reassemble the Starter Housing
- Position the recoil housing: Carefully place the recoil housing back onto the engine, ensuring it’s aligned correctly.
- Secure the screws: Replace the screws that hold the recoil housing in place, tightening them securely.
Step 5: Test the New Pull String
- Pull the handle: Pull the handle to test the new string’s operation. Ensure it retracts smoothly and the engine cranks over.
- Adjust tension if needed: If the string is too tight or too loose, adjust it by loosening or tightening the screws holding the handle assembly to the recoil housing.
Tips for Success
- Lubricate the recoil spring: Before installing the new string, apply a light coating of lubricant to the recoil spring to ensure smooth operation.
- Inspect the starter assembly: While you’re replacing the pull string, take the time to inspect the entire starter assembly for signs of wear or damage.

Frequently Asked Questions
What tools do I need to replace a lawnmower pull string?
You’ll need a few basic tools to replace a lawnmower pull string. These include:
- A Phillips screwdriver: This is used to remove the screws holding the recoil housing cover in place.
- A pair of pliers: These will be helpful for gripping and pulling the old string.
- A new pull string: Make sure you purchase the correct string for your model of lawnmower.
How do I know if my lawnmower pull string is broken?
A broken pull string can be easily identified by observing the symptoms. Firstly, if you try to start the lawnmower and the string doesn’t retract back into the housing after pulling, it’s a clear sign that it’s broken. Secondly, if you hear a snapping or tearing sound when pulling the string, it signifies a damaged or broken string.
How do I remove the old pull string?
The first step in removing the old pull string is to locate the recoil housing cover, usually found at the top of the engine. Carefully remove the screws holding the cover in place. Next, you’ll need to access the string itself. This might involve removing a spring or a small metal clip. Once the old string is exposed, use a pair of pliers to carefully pull it out from the housing.
How do I install the new pull string?
Installing the new string involves reversing the removal process. First, thread the new string through the housing, ensuring it’s securely attached to the recoil spring. Once the string is properly threaded, guide it through the handle and pull it back into the housing.
How do I adjust the tension of the new pull string?
The tension of the pull string determines how easily the lawnmower starts. To adjust it, locate the tension adjustment screw on the recoil housing. By turning this screw, you can increase or decrease the tension of the string. A properly adjusted string should offer resistance when pulled but not be overly tight.
What should I do if the new pull string breaks?
It’s not uncommon for a new pull string to break, especially if it’s not properly installed or if the recoil spring is faulty. If your new string breaks, inspect the installation to ensure it’s correctly threaded and secured. If everything appears to be in order, you might need to replace the recoil spring.
How do I know if I need to replace the recoil spring?
A worn-out or broken recoil spring can also cause issues with your pull string. If you’ve replaced the string multiple times and it continues to break, the spring is likely the culprit. You can check the spring for signs of damage, such as rust, cracks, or stretching. If the spring is damaged, it will need to be replaced.
