Ever tried to start your lawnmower, only to find the pull cord feeling limp and unresponsive? It’s a frustrating experience, leaving you stranded with a lawn that’s starting to resemble a jungle. Don’t worry, a broken pull cord is a common issue, and it’s often a simple fix! This comprehensive guide will walk you through the process of changing a lawn mower pull cord, step-by-step, so you can get your mower back in action quickly. We’ll cover everything from identifying the problem to finding the right replacement parts, making sure you have all the tools and knowledge needed to tackle this task with confidence.
A Quick Overview of Replacing a Lawn Mower Pull Cord
Replacing a broken lawn mower pull cord is a relatively straightforward DIY project. You’ll need a few basic tools, a new pull cord, and a little bit of time. The process involves disconnecting the old cord, detaching it from the engine, installing the new cord, and reconnecting it to the engine.
Identifying the Problem: Is It Really the Pull Cord?
Before diving into the replacement process, it’s important to ensure the problem truly lies with the pull cord. Here are a few things to check:
- Check the Recoil Starter: The pull cord is connected to a recoil starter assembly. A malfunctioning recoil starter, such as a broken spring, could be the source of the problem, making it seem like the cord itself is broken.
- Inspect the Cord for Tears or Breaks: Visually examine the pull cord for any obvious tears, frays, or breaks. If you see any damage, it’s likely the cord is the culprit.
- Check for Binding or Sticking: If the cord feels stiff or stuck when you pull it, there might be an issue with the recoil starter mechanism. This could be due to debris or corrosion.
Note: If you discover a problem with the recoil starter, you might need a replacement. However, this guide focuses on replacing the pull cord itself.
Tools and Materials You’ll Need
To replace your lawn mower pull cord, you’ll need the following:
- A New Pull Cord: Ensure you purchase a cord specifically designed for your lawn mower model.
- Phillips Screwdriver: This is used to remove and reattach the recoil starter cover.
- Wire Cutters or Pliers: These are helpful for trimming the excess cord.
- Gloves (Optional): Wearing gloves can protect your hands from cuts or scrapes while working.
- Work Area: Choose a clean, well-lit space for the repair.
Step-by-Step Guide to Replacing a Lawn Mower Pull Cord
Now that you’ve identified the problem and gathered the necessary tools, let’s tackle the replacement process:
1. Disconnecting the Pull Cord
Safety First: Before beginning, disconnect the spark plug wire to prevent accidental starts.

- Remove the Old Cord from the Engine: The old pull cord is usually held in place by a clip or a nut. Locate this point and remove the cord from the engine.
- Inspect the Old Cord: Examine the old cord to determine the cause of the failure. This will help you understand if there was a problem with the cord itself or the recoil starter mechanism.
3. Installing the New Pull Cord
- Thread the New Pull Cord: Thread the new pull cord through the engine housing, following the path of the old cord. Ensure the cord runs smoothly without any snags or kinks.
- Attach the New Pull Cord to the Engine: Secure the new pull cord to the engine using the clip or nut that held the old cord in place. Ensure it’s firmly attached.
4. Attaching the New Pull Cord to the Recoil Starter
- Locate the Recoil Starter Hook: The new pull cord has a hook or loop designed to attach to the recoil starter mechanism.
- Connect the New Pull Cord: Connect the new pull cord to the recoil starter mechanism, ensuring it’s securely attached.
5. Reassemble the Recoil Starter
- Reconnect the Pull Cord: Reattach the pull cord to the recoil starter mechanism.
- Replace the Recoil Starter Cover: Reinstall the recoil starter cover and secure it with the screws you removed earlier.
6. Test the New Pull Cord

- Test the New Cord: Try starting the lawnmower using the new pull cord. If it works properly, you’ve successfully replaced the pull cord!
Troubleshooting Common Issues
While replacing a pull cord is generally straightforward, sometimes you might encounter issues:
- The New Cord Won’t Pull Smoothly: Ensure the cord is properly threaded through the engine housing and there are no kinks or snags.
- The Engine Doesn’t Start: Check that the spark plug wire is properly connected and that the spark plug itself is working.
- The Recoil Starter Feels Stiff: If the recoil starter feels stiff or doesn’t retract properly, there might be an issue with the recoil starter mechanism. This could require further inspection or replacement.

FAQs
Q1: What are the common signs of a problem with the pull cord?
The most obvious sign is that your lawnmower won’t start when you pull the cord. You might also notice that the cord feels stiff or doesn’t recoil properly. Additionally, if the cord feels loose, you might have a broken spring. If the cord is frayed or broken, this could be another sign of a problem. If you experience any of these issues, it’s best to address them before your lawnmower stops working completely.
Q2: What is the first thing I should do to try and fix the pull cord?
The first step is to check the recoil spring. Over time, this spring can become weak or stretched. If the spring is not working correctly, it will make it difficult to start your lawnmower. You can often fix a weakened spring by tightening it. If the spring is broken, you’ll need to replace it.
Q3: What if the pull cord is frayed or broken?
A frayed or broken cord can be a safety hazard and needs to be replaced. The pull cord is attached to the recoil starter, and the cord could become entangled in the moving parts if it’s damaged. Replacing the cord is a relatively simple task, and you can find instructions online or in your lawnmower’s manual.
Q4: How do I tighten the recoil spring?
You’ll need a wrench and a flathead screwdriver for this task. Find the tension screw on the recoil starter and loosen it with the screwdriver. Then, using the wrench, turn the adjustment nut clockwise to tighten the spring. Make sure to test the cord after tightening to ensure it’s not too stiff.
Q5: What if the pull cord won’t come back after pulling it?
This usually indicates a problem with the recoil assembly. The rope is likely tangled or the pawl has become damaged. You will need to remove the cover to access the recoil assembly and check for any damage. You may need to replace the pawl or the entire recoil assembly.
Q6: Do I need to replace the entire pull cord system if one part is broken?
Often, you can replace only the broken part, such as the cord itself or the spring. However, if the entire recoil assembly is damaged, you will need to replace it. If you’re unsure, it’s best to consult with a qualified mechanic for advice.
Q7: Can I fix a broken pull cord myself?
In most cases, yes, you can fix a broken pull cord yourself. The process involves removing the recoil housing, replacing the broken component, and reassembling the housing. However, if you are not comfortable working with mechanical devices, it is best to seek professional help.
