How to Repair a Lawn Mower Pull String: A Step-by-Step Guide?

The warm weather has arrived, and your lawn is looking a little unkempt. You reach for your trusty lawnmower, only to find the pull string is broken. A frustrating situation, isn’t it? But don’t despair! This guide will walk you through the steps on how to repair a lawn mower pull cord, so you can get your lawn looking pristine in no time. We’ll cover everything from identifying common problems to replacing the cord itself.

The pull cord, also known as the recoil starter, is a vital component of your lawnmower. It provides the initial force to turn the engine, allowing you to start the machine. Over time, the pull cord can become worn, frayed, or even break completely, making it impossible to start the mower.

Identifying the Problem

Before you dive into the repair, you need to identify the exact issue. Is it a simple matter of a broken string, or is something more serious causing the problem? Here are some common scenarios:

  • The pull string is broken: This is the most common problem. The string may be frayed, worn, or even snapped entirely.
  • The pull string is stuck: The string may be tangled or caught on the recoil mechanism, preventing it from retracting.
  • The recoil mechanism is damaged: The recoil spring or other components may be worn or broken, preventing the string from pulling properly.

Tools and Materials

Before you begin, gather the following:

  • New pull cord: Make sure the new string is compatible with your lawnmower model. You can find these at most hardware stores or online.
  • Phillips screwdriver: You’ll need this to remove the recoil housing.
  • Needle-nose pliers: For manipulating and securing the string.
  • Safety glasses: Always wear safety glasses when working with tools.
  • Gloves: Protect your hands from any sharp edges.

How to Repair a Broken Pull String

1. Remove the Recoil Housing

  • Locate the recoil housing: The recoil housing is a round, plastic or metal housing that houses the pull cord mechanism. It is typically located on the top of the lawnmower engine.
  • Remove the screws: Use the Phillips screwdriver to remove the screws holding the recoil housing in place. These screws may be located around the perimeter of the housing.
  • Remove the housing: Carefully lift the recoil housing off the engine.

2. Inspect the Recoil Mechanism

  • Check for damage: Inspect the recoil mechanism for any damage, such as a broken spring, worn gears, or a tangled cord.
  • Clean the mechanism: Use a soft cloth to wipe away any dirt or debris.

3. Replace the Pull String

  • Remove the old string: Locate the end of the old pull cord and gently pull it out of the recoil housing. You may need to use the needle-nose pliers to help extract it.
  • Thread the new string: Feed the new pull string through the hole in the recoil housing and onto the recoil spring.
  • Secure the string: Use the needle-nose pliers to secure the new string to the recoil spring. Make sure it’s attached firmly.

4. Reassemble the Recoil Housing

  • Reinstall the housing: Place the recoil housing back onto the engine and align it with the mounting holes.
  • Secure the screws: Use the Phillips screwdriver to re-secure the screws holding the recoil housing in place. Tighten them snugly.

5. Test the New Pull String

  • Pull the string: Gently pull the new pull string to ensure it is retracting properly and the engine is turning over.
  • Repeat if necessary: If the string isn’t retracting correctly, you may need to adjust the tension on the recoil spring or re-thread the string. Refer to your lawnmower’s owner’s manual for specific instructions.

Fixing a Stuck Pull String

If your pull string is stuck, it may be tangled in the recoil mechanism. Here’s how to fix it:

  • Remove the recoil housing: Follow the instructions above to remove the recoil housing.
  • Untangle the string: Carefully untangle the string from the recoil mechanism.
  • Re-thread the string: Re-thread the string through the recoil mechanism, ensuring it’s properly secured to the spring.
  • Reassemble the housing: Put the recoil housing back on and re-secure the screws.

Repairing a Damaged Recoil Mechanism

If the recoil mechanism is damaged, replacing the entire assembly is often the best option. Here’s what you’ll need to do:

  • Remove the old mechanism: Follow the steps above to remove the recoil housing and remove the old recoil mechanism.
  • Install the new mechanism: Purchase a new recoil assembly that is compatible with your lawnmower model. Install the new mechanism in the housing.
  • Reassemble the housing: Secure the housing back onto the engine.

Tips for Maintaining Your Lawn Mower Pull Cord

  • Regularly inspect the pull cord: Check the cord for any signs of wear, fraying, or damage. Replace it as needed.
  • Keep the recoil mechanism clean: Remove dirt and debris from the mechanism to prevent it from jamming.
  • Store your mower properly: Store your mower in a dry place to prevent corrosion.
  • Use the proper starting procedure: Start your lawnmower correctly to avoid putting unnecessary stress on the pull cord.

Troubleshooting Common Pull Cord Problems

  • The pull string is too loose: Adjust the tension on the recoil spring by turning the adjustment screw located on the housing.
  • The pull string is too tight: Loosen the tension on the recoil spring by turning the adjustment screw in the opposite direction.
  • The pull string is not retracting: This could be due to a damaged spring, a tangled string, or a problem with the recoil mechanism. Refer to the troubleshooting section above or consult your owner’s manual.

When to Seek Professional Help

While many pull cord repairs are relatively simple, some situations may require professional assistance. If you encounter any of the following problems, it’s best to seek help from a qualified mechanic:

  • The recoil spring is broken: Replacing the spring can be difficult, especially on some models.
  • The recoil mechanism is severely damaged: If you are not comfortable working with machinery or if the damage is extensive, a mechanic can help you repair or replace the mechanism.
  • You are unsure of the repair process: If you are unsure about any step in the repair process, it’s best to consult a professional.
