A quick overview: A stuck lawnmower pull cord often occurs when the recoil spring has lost its tension, the cord itself is tangled or frayed, or there’s a blockage in the recoil housing. Fortunately, most of these issues can be resolved with simple repairs and a few basic tools. Let’s dive in!
Understanding the Lawn Mower Pull Cord System
Before we get into fixing a stuck pull cord, it’s important to understand how the system works. The pull cord is connected to a recoil spring, housed within a metal casing. When you pull the cord, you wind the spring, storing energy. This stored energy is then released, causing the engine to turn over.
Troubleshooting the Stuck Pull Cord
The first step to fixing a stuck pull cord is to troubleshoot the problem. This will help you identify the root cause and determine the best course of action.
1. Check for Tangled or Frayed Cord
The most common culprit for a stuck pull cord is a tangled or frayed cord. The cord can get caught on itself or on other parts of the mower, preventing it from retracting smoothly.
Here’s how to check:
- Inspect the cord: Carefully look for any tangles or fraying, especially near the handle and the recoil housing.
- Gently pull the cord: Try to gently pull the cord out and back in to see if it moves freely.
- Look for any visible obstructions: Make sure there are no objects caught in the pull cord housing.
If you find any tangles or fraying, you’ll need to replace the cord. A new cord can be purchased from your local hardware store or online.
2. Examine the Recoil Spring
The recoil spring is responsible for storing and releasing the energy needed to start the engine. If the spring is worn out or has lost its tension, the pull cord won’t retract properly.
Here’s how to check the recoil spring:
- Remove the pull cord handle: This typically involves loosening a nut or screw on the handle.
- Inspect the spring: Look for any signs of wear, rust, or damage.
- Test the spring tension: Gently pull the cord out and let it retract. The spring should retract the cord smoothly and quickly.
If the spring is worn out, you’ll need to replace it. You can find replacement springs at most hardware stores.
3. Look for Obstructions
Sometimes, a stuck pull cord can be caused by something blocking the recoil housing. This could be debris, grass clippings, or even a small piece of metal.
Here’s how to check for obstructions:
- Remove the pull cord handle: This will give you access to the recoil housing.
- Inspect the housing: Look for any visible obstructions.
- Use a small tool to remove any debris: A small screwdriver or pliers can be helpful for removing any debris.
Once you’ve cleared any obstructions, test the pull cord again to see if it’s working properly.
Replacing the Lawn Mower Pull Cord
If the cord itself is frayed or damaged, you’ll need to replace it. Here’s a step-by-step guide:
- Disconnect the spark plug: This is a safety precaution to prevent accidental starting.
- Remove the old cord: Depending on your lawnmower, you may need to remove the pull cord handle or access the cord from the recoil housing.
- Unhook the old cord from the recoil spring: This involves removing a small clip or spring.
- Attach the new cord to the recoil spring: Make sure the cord is properly secured.
- Reattach the pull cord handle: Secure the handle with the nut or screw.
- Reconnect the spark plug: Make sure the spark plug wire is securely connected to the plug.
Replacing the Recoil Spring
If the recoil spring is worn out, you’ll need to replace it. Here’s how to do it:
- Disconnect the spark plug: This is a safety precaution to prevent accidental starting.
- Remove the pull cord handle: This will give you access to the recoil housing.
- Remove the old spring: This involves removing a few screws or clips that hold the spring in place.
- Install the new spring: Make sure the spring is properly installed and secured with the screws or clips.
- Reattach the pull cord handle: Secure the handle with the nut or screw.
- Reconnect the spark plug: Make sure the spark plug wire is securely connected to the plug.
Preventing Future Problems
You can take some steps to prevent future issues with your lawnmower pull cord:
- Inspect the cord regularly: Check for tangles, fraying, or any signs of wear.
- Keep the recoil housing clean: Remove any debris or grass clippings that can accumulate inside.
- Store the lawnmower properly: When not in use, store the lawnmower in a dry place and avoid exposing it to extreme temperatures.
Seeking Professional Help
If you’re still having trouble with your stuck pull cord, or if you’re not comfortable with the repairs, it’s best to seek professional help. A qualified mechanic can diagnose the problem and provide a solution.

FAQ
What is a stuck pull cord?
A stuck pull cord means that when you pull on the cord to start the lawnmower engine, it doesn’t recoil back into the housing. This indicates a problem with the mechanism that allows the cord to retract. The issue can be caused by various factors, including a broken spring, a tangled cord, or a jammed recoil assembly.
If the pull cord doesn’t return, the engine won’t start, as the cord is responsible for initiating the combustion process. To fix this, you’ll need to identify and address the cause of the stuck cord, which may require dismantling the housing and inspecting the internal components.
What are the possible causes of a stuck pull cord?
Several factors can contribute to a stuck lawnmower pull cord. A common culprit is a broken spring, which is responsible for pulling the cord back into the housing. Other potential causes include a tangled cord, a jammed recoil assembly, or excessive wear on the cord itself.
If the cord is frayed or worn, it can snag on the housing or the recoil assembly, preventing it from retracting properly. Additionally, dirt, debris, or excessive lubrication can accumulate in the recoil mechanism, interfering with its smooth operation.
How can I fix a stuck pull cord?
Fixing a stuck pull cord typically involves inspecting the recoil assembly and addressing any issues found. If the spring is broken, it will need to be replaced. If the cord is tangled, you’ll need to untangle it carefully. If the recoil assembly is jammed, you may need to clean it or replace worn parts.
For a broken spring, you will likely need to replace the entire recoil assembly. For a tangled cord, carefully untangle it, being mindful not to damage it further. If the recoil assembly is jammed, you can try cleaning it with compressed air or a small brush. If the parts are worn, they may need to be replaced.
How do I know if the spring is broken?
A broken spring is a common cause of a stuck pull cord. To determine if the spring is the problem, you can carefully remove the pull cord housing and inspect the spring itself. Look for any signs of breakage, such as a visible crack or a section that’s completely detached.
If the spring is broken, you will need to replace it. This usually requires replacing the entire recoil assembly, as the spring is often integrated into the assembly. You can find replacement recoil assemblies at most hardware stores and online retailers.
What if the cord is tangled?
A tangled cord can also prevent it from retracting properly. If you suspect a tangle, carefully remove the pull cord housing and inspect the cord. Try to gently untangle the cord, being cautious not to damage it.
Once you’ve untangled the cord, make sure to re-insert it correctly into the recoil assembly. Ensure the cord is properly seated and that there are no kinks or twists. If the cord is damaged, you may need to replace it.
What if the recoil assembly is jammed?
A jammed recoil assembly can be caused by dirt, debris, or excessive lubrication. To fix this, you can try cleaning the assembly with compressed air or a small brush. You can also apply a small amount of light oil to the moving parts to lubricate them.
If cleaning the assembly doesn’t solve the problem, you may need to replace the entire assembly. This is especially true if the parts are worn or damaged. Before replacing the assembly, make sure to disconnect the spark plug to prevent accidental starting.
What safety precautions should I take when fixing a stuck pull cord?
When working on a lawnmower, it’s essential to prioritize safety. Always disconnect the spark plug to prevent accidental starting. Wear safety glasses to protect your eyes from flying debris. Also, use a wrench to remove the recoil housing and be careful not to damage the components.
Always refer to the owner’s manual for specific instructions and safety precautions related to your particular lawnmower model. If you are uncomfortable working on the lawnmower yourself, it’s best to take it to a qualified mechanic.
