How to Fix a Lawn Mower Pull Cord: A Step-by-Step Guide?

The warm weather is finally here, and you’re ready to get your lawn looking its best. You grab your trusty lawn mower, pull the cord, and…nothing. The engine sputters, coughs, and refuses to start. The dreaded broken pull cord. A common problem, but one that can be easily fixed with the right knowledge. This guide will walk you through the common issues that can cause a broken pull cord and how to repair them, saving you time and money.

In essence, a lawn mower pull cord is a simple but critical component, responsible for transferring the user’s force to the engine’s crankshaft. It consists of a cord, a handle, a spring, and a recoil assembly. When the cord is pulled, the spring unwinds, providing the necessary force to spin the engine. A broken pull cord can be caused by a variety of issues, from a worn-out cord to a broken spring or a damaged recoil assembly. By understanding the common problems and troubleshooting techniques, you can quickly restore your lawn mower to its former glory.

Identifying the Problem: What’s Wrong with Your Pull Cord?

The first step in fixing a broken lawn mower pull cord is to identify the problem. This can be done by observing the symptoms and performing some basic checks. Here’s how to diagnose the issue:

1. Inspect the Pull Cord:

  • Check for fraying or breaks: The pull cord itself can wear out over time, especially if it’s frequently used. Look for frayed or broken fibers, which can indicate a weak or damaged cord. If the cord is frayed, it’s best to replace it altogether.
  • Ensure the cord is securely attached to the handle: The cord should be firmly attached to the handle. If the cord is loose or detached, it won’t be able to transfer the pulling force effectively.
  • Check for excessive slack: A loose pull cord can be a sign of a worn spring, making it difficult to start the engine. The cord should have a slight amount of tension when pulled, but not so much that it feels stiff.

2. Check the Recoil Assembly:

The recoil assembly is the mechanism that stores and releases the spring tension. It’s housed within the engine casing and contains a series of gears and a spring.

  • Look for damage or wear: Inspect the recoil assembly for any signs of damage, such as cracks, broken teeth, or excessive wear. If you see any signs of damage, the assembly may need to be replaced.
  • Ensure the spring is intact and functioning correctly: The spring is responsible for providing the force to spin the engine. Check that the spring is not broken or damaged.

3. Inspect the Engine Starter:

  • Examine the starter for damage or wear: The engine starter is the component that connects the pull cord to the crankshaft. Check for any signs of damage or wear, such as broken teeth or a loose connection. If you find any issues, the starter may need to be replaced.

FAQ

What should I do if the pull cord won’t recoil?

If the pull cord won’t recoil, it likely means the spring is broken or has come unhooked. To fix this, you’ll need to access the spring mechanism by removing the housing covering the pull cord. Inspect the spring for any breaks or signs of wear and tear. If the spring is broken, you’ll need to replace it. If it’s simply unhooked, carefully reattach it to the appropriate hook.

Once you’ve addressed the spring issue, reassemble the housing and test the pull cord. It should recoil smoothly and easily. If not, there may be a more significant problem with the recoil system that requires professional attention.

How do I know if the pull cord is broken?

A broken pull cord will often have a visible tear or fraying, making it easy to identify. If you can’t see any damage, try pulling the cord and see if it feels weak or snaps back easily. A broken pull cord will feel loose and might even break completely when pulled.

Another sign is if the cord feels stiff or doesn’t move at all when you try to pull it. This could indicate the cord has become tangled inside the housing or has been damaged in a way that prevents it from moving freely.

What if the pull cord is stuck?

If your pull cord is stuck, the issue might be a tangled cord, a jammed starter mechanism, or a problem with the recoil spring. Begin by gently tugging on the cord to see if you can free it. If the cord doesn’t move, you’ll need to open the housing.

Once inside, inspect the cord and remove any tangles. Check the starter mechanism for any obstructions. If you find any issues, address them accordingly. If the spring is the culprit, it might need to be replaced.

Why does the pull cord feel stiff or hard to pull?

A stiff or hard-to-pull cord can be caused by several factors. The most common issue is a worn or damaged recoil spring. A weakened spring won’t provide enough force to pull the cord back smoothly. Another possibility is a clogged or dirty starter mechanism, which can impede the cord’s movement.

To resolve this, you can try cleaning the starter mechanism and applying a lubricant like WD-40. If the problem persists, it’s likely the spring needs replacement.

Can I replace the pull cord myself?

Replacing a pull cord is generally a straightforward task. However, the process can vary depending on the mower model and the type of cord. It’s best to consult your mower’s manual for specific instructions.

Essentially, you’ll need to remove the housing covering the cord, detach the old cord, and install the new one. Ensure you follow the instructions carefully and use the correct type of cord. If you’re not comfortable with DIY repairs, it’s always best to seek help from a professional.

What tools do I need to fix the pull cord?

The necessary tools for fixing a pull cord depend on the specific issue you’re dealing with. However, some basic tools will come in handy:
