This comprehensive guide will walk you through the process, providing step-by-step instructions, troubleshooting tips, and important safety considerations. By the end, you’ll be equipped to tackle this common lawn mower issue with confidence.
A Quick Overview
Replacing a lawn mower pull cord is a straightforward process that involves detaching the old cord, threading the new one through the recoil housing, and attaching it to the engine. While the specific steps may vary slightly depending on your mower’s model, the overall principles remain the same. This article will guide you through each stage, offering practical tips and addressing potential challenges you might encounter.
Step 1: Gathering Your Supplies
Before you start, ensure you have the following:
- A new pull cord: Choose a cord specifically designed for your lawn mower. It should match the length and thickness of the original cord.
- A Phillips screwdriver: This will be used to remove screws and access the recoil housing.
- A pair of pliers: These will come in handy for manipulating the cord and holding parts in place.
- Work gloves: Protect your hands from any sharp edges or potential oil spills.
Step 2: Disconnecting the Old Pull Cord
- Locate the recoil housing: This is the round, usually black, housing on the side of your mower where the pull cord is attached.
- Release the tension: Look for a small spring-loaded button or lever near the recoil housing. Press or pull it to release the tension on the cord.
- Remove the old cord: Once the tension is released, gently pull the cord out of the housing. You might need to use pliers to help remove it if it’s stuck.
Step 3: Preparing the New Pull Cord
- Inspect the new cord: Ensure it’s in good condition with no frays or breaks.
- Thread the cord: Locate the opening on the recoil housing where the cord attaches. It will usually be near the bottom or the side of the housing.
- Feed the cord through: Carefully thread the new pull cord through the opening and into the housing. This part might require a little patience, and you may need to use pliers to guide the cord through tight spaces.
Step 4: Attaching the New Pull Cord
- Identify the attachment points: The new pull cord will typically have two ends. One end will have a small hook or loop for attaching to the recoil spring, while the other end will have a smaller hook or loop to be attached to the engine shaft.
- Attach the recoil end: Locate the recoil spring, which is a metal spring inside the recoil housing. Hook the larger end of the new cord onto the recoil spring. This will require some strength to pull the cord tight.
- Attach the engine end: Locate the engine shaft on the other side of the housing. It will have a small hole or slot where the cord’s smaller end needs to be attached. Securely hook the small end of the cord onto the shaft.
Step 5: Testing and Final Adjustments
- Rewind the pull cord: Once the cord is attached, pull it out completely and then allow it to rewind back into the housing. Make sure it rewinds smoothly without any snags.
- Test the pull start: Attempt to start your mower using the new pull cord. It should start smoothly without excessive effort.
- Adjust as needed: If the pull cord is too loose or too tight, you may need to make minor adjustments to the recoil housing. Consult your owner’s manual or search for specific instructions online for your mower model.
Troubleshooting Common Issues
While installing a new pull cord is generally straightforward, you might encounter some hiccups along the way. Here are some common issues and their solutions:
The Pull Cord Doesn’t Rewind Smoothly
- Problem: The cord might be tangled or stuck inside the housing.
- Solution: Carefully remove the cord and rethread it, making sure it’s properly aligned and untangled. If the issue persists, check for obstructions or damage inside the recoil housing.
The Pull Cord Is Too Tight or Too Loose
- Problem: Improper tension adjustment can cause the cord to be too difficult or too easy to pull.
- Solution: Most recoil housings have an adjustment mechanism. Consult your owner’s manual to find out how to adjust the tension. You might need to loosen or tighten screws to achieve the desired tension.
The Pull Cord Breaks Soon After Installation
- Problem: A faulty cord, poor quality, or improper installation can cause premature breakage.
- Solution: Ensure you are using a high-quality cord specifically designed for your mower model. Double-check your installation process and make sure the cord is securely attached to both the recoil spring and engine shaft. If the issue persists, it might be a sign of a faulty recoil housing, which may require professional repair.
Safety Considerations
- Disconnect the spark plug: Always disconnect the spark plug before working on your mower’s engine. This will prevent accidental starting and potential injuries.
- Wear safety glasses: Protect your eyes from any potential debris or flying objects.
- Work in a well-ventilated area: Avoid working on your mower in enclosed spaces to prevent inhaling harmful fumes.
- Use caution when handling sharp objects: Be careful when working with the recoil housing and other parts that may have sharp edges.

3. How often should I replace my lawn mower pull cord?
The lifespan of a lawn mower pull cord varies depending on usage and the quality of the cord itself. A general rule of thumb is to replace it every few years or whenever it starts to fray, show signs of wear and tear, or becomes difficult to pull.
You can also check the condition of the recoil spring, which is responsible for retracting the pull cord. If the spring is weak or broken, you’ll need to replace it as well. This will help ensure your lawn mower starts smoothly and reliably.

If your lawn mower pull cord breaks while you’re mowing, it’s important to stop the engine immediately and assess the situation. If the cord has completely detached, you may be able to manually pull the engine over to get it running. However, this is not recommended as it can be dangerous.
If the cord has snapped, but is still attached to the recoil spring, you can try to use a piece of rope or wire to connect the cord to the engine. This will allow you to pull the engine over and start the lawn mower. However, it’s crucial to be extremely cautious and ensure that the rope or wire is securely attached before attempting to start the engine.
5. Can I use any type of cord for my lawn mower?
No, not all cords are created equal. It’s important to use a cord specifically designed for lawn mowers. These cords are typically made of durable materials that can withstand the wear and tear of repeated use.
