The whirring blades of your lawn mower are ready to tackle your overgrown grass, but suddenly, silence. You pull the cord, but instead of the satisfying roar of the engine, you’re met with a limp, lifeless rope. A broken pull cord can quickly turn your lawn care routine into a frustrating experience. But don’t fret! This article will guide you through the steps to diagnose and fix a broken pull cord, helping you get back to mowing in no time. We’ll explore common issues, like a frayed cord, a broken spring, or a stuck recoil mechanism, and walk you through the necessary repairs.
Overview:
A broken pull cord on your lawnmower is often a simple issue that can be fixed with basic tools and a bit of know-how. The pull cord system relies on a spring, a recoil mechanism, and a cord that connects to the engine. When the cord is pulled, the spring releases its tension, rotating the engine crankshaft and starting the mower.
Identifying the Problem:
Before diving into the repair, it’s crucial to pinpoint the exact cause of the broken pull cord. The most common culprits are:
1. Frayed or Broken Pull Cord:
- Signs: The cord is visibly frayed, ripped, or completely broken.
- Reason: Constant use, exposure to weather, or accidental snags can damage the cord.
2. Broken or Worn-Out Spring:
- Signs: The cord pulls easily with minimal resistance, or the engine struggles to start even with a new cord.
- Reason: The spring weakens over time, losing its ability to provide enough tension to start the engine.
3. Stuck Recoil Mechanism:
- Signs: The cord feels stiff or difficult to pull, or it doesn’t retract fully after pulling.
- Reason: Dirt, debris, or wear and tear can cause the mechanism to jam.
Fixing a Frayed or Broken Pull Cord:
Replacing a broken or frayed pull cord is a simple fix:
1. Locate the Pull Cord Housing: This is typically located under a cover or behind a panel on the mower’s engine.
2. Remove the Old Cord: The cord is usually attached to the recoil mechanism with a clip or a knot. Gently unfasten the cord from the recoil mechanism and remove the old cord.
3. Install the New Cord: Thread the new cord through the housing and attach it to the recoil mechanism using the same method as the old cord. Ensure the cord is securely fastened.
4. Reassemble the Housing: Securely replace the cover or panel and test the new cord.
Fixing a Worn-Out Spring:
A worn-out spring requires a more involved repair:
1. Access the Recoil Mechanism: Locate the recoil housing and remove the cover or panel.
2. Remove the Old Spring: The spring is usually held in place by a retaining clip or a small bolt. Remove the spring carefully.
3. Install the New Spring: Insert the new spring into the mechanism, ensuring it’s properly seated and aligned.
4. Secure the Spring: Reinstall the retaining clip or bolt to secure the new spring.
5. Reassemble the Housing: Replace the cover or panel, and test the repaired pull cord system.
Troubleshooting a Stuck Recoil Mechanism:
A jammed recoil mechanism can be a bit trickier to fix:
1. Clean the Mechanism: Carefully remove the recoil housing cover. Use a brush, compressed air, or a vacuum cleaner to remove any dirt, debris, or grass clippings that might be jamming the mechanism.
2. Lubricate the Mechanism: Apply a few drops of light oil to the moving parts of the mechanism, such as the spring and the pawl. This helps reduce friction and prevent future jamming.
3. Test the Mechanism: Reassemble the housing and test the pull cord. If the cord still feels stiff, you may need to further inspect the mechanism for any internal damage or wear and tear.
Preventing Future Issues:
Taking a few preventative steps can help you avoid a broken pull cord in the future:
- Regular Maintenance: Inspect the pull cord for wear and tear after each use.
- Clean Regularly: Remove any dirt, debris, or grass clippings from the pull cord housing and the recoil mechanism.
- Lubricate the Mechanism: Apply a small amount of oil to the moving parts of the mechanism to keep it smooth and prevent jamming.
Conclusion:
A broken pull cord can be a frustrating inconvenience, but it’s usually an easy fix. By following the steps outlined in this article, you can quickly diagnose and repair the problem, getting your lawn mower back in action and keeping your lawn looking its best. Remember to always practice safety when working on your lawn mower, and consult your owner’s manual for specific instructions and diagrams for your model.
FAQs
1. What are the signs of a broken pull cord?
The most obvious sign of a broken pull cord is that the engine won’t start when you pull the cord. You might hear a clicking sound or feel resistance as you pull, but the engine won’t turn over. Another sign is if the cord feels loose or doesn’t retract properly after pulling. If you notice any of these signs, it’s time to inspect your pull cord and potentially replace it.
2. Can I just replace the broken part of the pull cord?
While it might seem like you can simply replace the broken part of the cord, it’s generally not recommended. The cord is designed as a single unit, and replacing just a portion can lead to inconsistent tension and potential future problems. It’s best to replace the entire pull cord for a reliable and long-lasting fix.
3. What tools do I need to replace the pull cord?
You’ll need a few basic tools to replace the pull cord on your lawnmower. These include a screwdriver (typically Phillips head), a pair of pliers, and potentially a wrench. Some lawnmowers may require specialized tools, but most can be repaired with these basic tools.
4. How long does it take to replace a pull cord?
The time it takes to replace a pull cord varies depending on the type of lawnmower and your familiarity with the process. For most models, it should take around 15-30 minutes. However, some mowers may require more time due to complicated housings or difficult access to the pull cord mechanism.
5. Can I do this myself, or should I call a professional?
Replacing a pull cord is a relatively simple repair that most homeowners can handle themselves. However, if you’re not comfortable working on mechanical equipment or if your mower has a particularly complicated design, it’s best to consult a professional mechanic. They can ensure the repair is done correctly and prevent potential damage to your lawnmower.
6. How often should I inspect my pull cord?
While you should inspect your pull cord regularly, especially if you notice any issues, a good rule of thumb is to check it once or twice a year, especially before the start of mowing season. This will help you catch any potential problems early and avoid unexpected breakdowns.
7. Can I use a different type of pull cord for my mower?
It’s generally not recommended to use a different type of pull cord for your mower. Pull cords are specifically designed for each mower model, and using an incompatible one could lead to improper tension, reduced lifespan, and potential damage to the engine. Always refer to your mower’s owner’s manual for the correct pull cord type and replacement instructions.
