The satisfying roar of a lawn mower engine is a summer soundtrack we all know and love. But what happens when that familiar pull cord starts to fray, snap, or simply refuse to pull? A broken pull cord can quickly turn a simple lawn care task into a frustrating ordeal. Fear not, fellow gardeners! This comprehensive guide will walk you through the process of changing your lawn mower’s pull cord, ensuring you’re back to mowing your perfect lawn in no time. We’ll cover everything from identifying the necessary tools and parts to troubleshooting common issues, making this DIY repair a breeze.
Essentially, changing a pull cord involves disconnecting the old cord, attaching a new one, and reconnecting the components. This process varies slightly depending on your specific lawn mower model, but the core steps remain the same.
Getting Started: Tools and Parts You’ll Need
Before diving into the task, it’s crucial to have the right equipment on hand. Here’s a list of the tools and parts you’ll need to successfully replace your lawn mower’s pull cord:
- New pull cord: Make sure to purchase a cord specifically designed for your lawn mower model. You can find replacement cords at most hardware stores, lawn care centers, or online retailers.
- Phillips screwdriver: This is essential for removing screws that secure the recoil assembly.
- Needle-nose pliers: These are helpful for manipulating the pull cord and connecting it to the recoil assembly.
- Wire cutters or scissors: These are used to cut the old pull cord.
- Work gloves: Wear gloves for added protection and grip while working with the pull cord.
Step 1: Disassembling the Recoil Assembly
- Locate the Recoil Assembly: The recoil assembly is usually located on the top of the engine, housing the pull cord and spring mechanism.
- Remove the Housing Cover: Depending on your lawn mower model, there may be screws or clips securing the housing cover. Use a Phillips screwdriver to remove any screws, or carefully pry open the cover using a flathead screwdriver if clips are present.
- Disconnect the Old Cord: The old pull cord will be attached to the recoil assembly, typically with a loop or a small metal clip. Using needle-nose pliers, gently remove this connection.
- Remove the Old Cord: Carefully pull the old cord out of the housing. If the cord is completely frayed or tangled, use wire cutters to cut it into manageable sections for easier removal.
Step 2: Installing the New Pull Cord
- Prepare the New Cord: If the new pull cord comes with a metal end loop, attach it to the recoil assembly using the existing hook or loop. If your cord doesn’t have a pre-attached loop, you’ll need to create one using a small piece of wire or a metal ring.
- Thread the New Cord: Carefully thread the new cord through the recoil assembly, following the path of the old cord. Ensure it passes through all the necessary guides and pulleys.
- Connect to the Recoil Assembly: Attach the free end of the new cord to the recoil assembly. Use needle-nose pliers to secure it properly.
Step 3: Reassembling and Testing
- Reinstall the Housing Cover: Once the new cord is securely in place, carefully replace the housing cover and tighten the screws or clips.
- Test the Pull Cord: Gently pull the new cord a few times to ensure it operates smoothly and engages the engine properly.
- Troubleshooting: If the engine doesn’t start, check for any loose connections or obstructions within the recoil assembly.
Common Issues and Troubleshooting Tips
- Cord Doesn’t Engage the Engine: Ensure the cord is securely attached to both the recoil assembly and the engine crank. Check for any obstructions that might prevent the cord from fully retracting.
- Cord Snaps or Breaks Easily: Replace the cord with a heavier-duty option designed for your lawn mower model.
- Spring Tension Issues: The spring inside the recoil assembly might be worn or broken, causing the cord to feel loose or difficult to pull. Consider replacing the spring if necessary.
- Engine Doesn’t Start After Replacing the Cord: Check the spark plug, fuel line, and carburetor to ensure they are functioning correctly. A malfunctioning spark plug or clogged carburetor can prevent the engine from starting even with a new pull cord.

Frequently Asked Questions
1. What tools do I need to change a pull cord on a lawn mower?
You’ll need a few basic tools to change a pull cord on your lawn mower. The most important is a Phillips-head screwdriver as many mowers use these screws to hold the pull cord housing in place. You may also need needle-nose pliers to help remove the old cord and install the new one. Finally, a small pair of scissors or a utility knife can be helpful for trimming excess cord length.
Having the right tools makes the process smoother and prevents frustration. You can likely find these tools around your home or at a local hardware store. Ensure you have these handy before beginning the replacement process.
2. How do I know if my pull cord needs to be replaced?
There are a few signs that indicate your lawn mower’s pull cord needs replacement. The most obvious is if the cord breaks or frays. You might also notice the cord becoming stiff or difficult to pull, which could indicate internal wear and tear. If the engine starts with a weak pull, it could mean the cord isn’t transferring enough force to the engine.
Finally, if you see the cord slipping out of the housing when you pull it, it’s a clear indication that the cord needs to be replaced. These signs are all indicators that the cord may be worn out and requires replacement to ensure proper engine starting.
3. Where can I find a replacement pull cord for my lawn mower?
You can find replacement pull cords at several places. The most convenient option is often your local hardware store, as they usually stock common parts for lawn mowers. You can also search for replacement cords online through retailers like Amazon or eBay, often with a wider selection and potential for better pricing.
Finally, you can check the manufacturer’s website for the specific model of your lawn mower, which might list authorized dealers or online retailers where you can purchase a replacement cord.
4. Can I use any pull cord for my lawn mower?
While most pull cords are relatively universal, it’s essential to ensure you get a cord specifically designed for your lawn mower model. Different models can have varying lengths, diameters, and connections to the engine. Using a wrong size or type of pull cord could lead to problems starting the engine or damage to the pull start system.
To find the right cord, check the manufacturer’s specifications or the original cord for details like the length, diameter, and connection type. If you are unsure, consult with a lawn mower repair professional for advice.
5. How often should I replace the pull cord on my lawn mower?
There’s no set timeline for replacing a pull cord. Its lifespan depends on factors like usage, quality, and how well it’s been maintained. If you notice signs of wear and tear, such as fraying or stiffness, it’s a good idea to replace it. Generally, most pull cords last for several years with regular use and proper care.
However, excessive use or harsh conditions can shorten the lifespan of a pull cord. If you use your lawn mower frequently or in demanding conditions, it’s wise to inspect the cord regularly for signs of wear and tear and replace it when necessary.
6. Can I lubricate the pull cord to make it easier to pull?
Lubricating a pull cord is not recommended. While it might seem like a good idea to make pulling easier, lubricants can attract dirt and debris, creating a sticky mess and eventually interfering with the cord’s function. Instead, focus on ensuring the pull start mechanism is clean and free of obstructions, which will provide the most smooth and easy pull.
If you find the cord is stiff, inspect the pull start housing for any clogs or buildup, and clean it using a soft brush or compressed air. A clean and unobstructed pull start mechanism will make starting your mower much smoother.
7. What should I do if I encounter any problems while changing the pull cord?
If you encounter any difficulties while changing the pull cord, it’s best to seek assistance from a qualified mechanic or repair professional. They can diagnose the issue, provide proper guidance, and potentially fix any underlying problems with the pull start mechanism.
Trying to force or manipulate parts can lead to further damage. Consulting a professional ensures that the repair is done correctly and safely, preventing future issues and ensuring your lawn mower’s longevity.
