The first warm days of spring bring with them the joyous task of tending to our lawns. But what happens when that beloved lawnmower, the one that hums a satisfying tune as it mows the perfect stripes, suddenly refuses to start? A frustratingly limp pull cord can turn a simple chore into a battle of wills. But fear not, fellow lawn enthusiasts! This guide will walk you through the process of recoiling your lawnmower pull cord, empowering you to tackle this common problem and get back to the satisfying rhythm of mowing.
In a nutshell, recoiling a lawnmower pull cord involves rewinding the cord back onto the recoil spring, ensuring a smooth and efficient pull for starting the engine. This process typically requires removing the pull cord assembly from the mower, carefully unwinding the cord, and then winding it back onto the spring in the correct direction.
Understanding the Mechanics: The Recoil System
Before diving into the steps, it’s helpful to grasp the basic workings of a recoil system. It’s a beautifully simple yet effective mechanism that transforms the pull of the cord into the rotational energy needed to spin the engine’s crankshaft.
The Components of the Recoil System
- Pull Cord: This is the rope you pull. It’s attached to a spool that winds around the recoil spring.
- Recoil Spring: The heart of the system. This spring is coiled within the recoil housing and stores energy when pulled.
- Recoil Housing: A protective casing that houses the spring and the mechanism for winding and unwinding the cord.
- Pawl and Ratchet: These components prevent the recoil spring from unwinding too quickly, ensuring a controlled pull.
How it Works
- When you pull the cord, the spool rotates, stretching the recoil spring.
- The stored energy in the spring is then released, causing the spool to spin rapidly, engaging the engine’s crankshaft.
- The pawl and ratchet mechanism ensure a controlled unwinding of the spring, preventing it from abruptly releasing all its stored energy.
Recoil a Lawn Mower Pull Cord – Step-by-Step
Now, let’s get our hands dirty and tackle the process of recoiling that stubborn lawnmower pull cord.
1. Gather Your Tools and Prepare the Area
You’ll need a few basic tools for this job.
- Screwdriver: A Phillips head screwdriver is usually needed to remove the recoil housing screws.
- Work Area: Choose a clean and well-lit space to work on the mower.
2. Remove the Recoil Housing
- Locate the Recoil Housing: It’s typically found on the top of the engine, housing the pull cord.
- Remove Screws: Using your screwdriver, carefully remove the screws holding the recoil housing in place.
- Lift the Housing: Once the screws are out, gently lift the recoil housing away from the engine.
3. Unwinding the Cord
- Inspect the Cord: Look for any signs of damage to the cord or the spool. If the cord is broken or severely frayed, you’ll need to replace it.
- Start Unwinding: Gently pull the cord out of the housing, unwinding it from the recoil spring.
4. Winding the Cord Back Onto the Spring
- Positioning the Cord: Hold the end of the cord and the spool in your hands.
- Winding the Cord: Carefully begin winding the cord back onto the spring, ensuring it’s wound in the same direction as the original winding. The spool should rotate smoothly without any resistance.
- Maintain Tension: Apply gentle tension to the cord as you wind it. This helps to ensure a secure winding and a smooth pull later on.
5. Reassemble the Recoil Housing
- Secure the Housing: Once the cord is fully wound, carefully align the recoil housing back onto the engine.
- Replace the Screws: Secure the housing by reinstalling the screws.
6. Test Your Work
- Pull the Cord: Give the pull cord a few test pulls to ensure it’s winding and unwinding smoothly.
- Check for Resistance: There should be a slight resistance as you pull the cord, but it should not feel excessively stiff or loose.
Common Problems and Solutions
While recoiling a lawnmower pull cord is a straightforward process, you might encounter some challenges.
1. The Cord is Stuck or Jammed
Possible Causes:
* Foreign Debris: Dust, dirt, or grass clippings can accumulate within the recoil housing and jam the cord.
* Worn Pawl or Ratchet: These components can wear out over time, causing the cord to stick.
Solutions:
* Clean the Housing: Remove any debris from the recoil housing and the pawl and ratchet mechanism.
* Replace Worn Parts: If the pawl or ratchet is worn, it may need to be replaced.
2. The Spring is Weak or Broken
Possible Causes:
* Excessive Use: Frequent use of the lawnmower can cause the spring to lose tension over time.
* Incorrect Winding: Winding the cord in the wrong direction can damage the spring.
Solutions:
* Replace the Spring: If the spring is weak or broken, it’s essential to replace it with a new one.
Tips for Maintaining Your Lawn Mower Pull Cord
- Regular Cleaning: Clean the recoil housing regularly to prevent debris from accumulating.
- Proper Storage: Store your lawnmower in a dry, dust-free area to prevent damage to the pull cord and recoil system.
- Avoid Over-Stretching: Do not pull the cord excessively beyond its intended range.
Wrapping Up: The Power of a Smooth Pull
With a little bit of patience and these simple instructions, you’ll be able to revive that tired pull cord and get your lawnmower humming again. A smooth, responsive pull cord not only makes starting your mower a breeze, but it also ensures proper engine operation, contributing to a healthy and well-maintained lawnmower.
Remember, a well-maintained lawnmower is a joy to use, so take care of its vital components and enjoy the satisfying symphony of your garden as you tackle those lush green patches!
FAQs
What is a recoil starter, and how does it work?
A recoil starter is a mechanism on a lawnmower that utilizes a spring to start the engine. When you pull the cord, it winds up the spring, storing energy. Then, as the cord is released, the stored energy in the spring rotates the engine’s crankshaft, turning the engine over and initiating combustion.
Why does the pull cord need to be recoiled?
The pull cord can become stretched or worn out over time, which can make it difficult to start the engine. Rewinding the cord ensures that it maintains its tension and can effectively engage the recoil starter mechanism.
How do I know if my pull cord needs to be recoiled?
If you notice that the pull cord is loose, has lost its springiness, or doesn’t retract smoothly, it’s a good indicator that it needs to be recoiled. You might also have trouble starting your mower, or the cord might feel like it’s slipping.
How often should I recoil the pull cord?
There’s no set schedule for recoiling the pull cord. However, you should check it periodically, especially if you use your lawnmower frequently or notice any signs of wear and tear. Regular checks help ensure that your lawnmower starts easily and efficiently.
What tools do I need to recoil the pull cord?
You’ll typically need a few basic tools, such as a flathead screwdriver, a Phillips screwdriver, and a pair of pliers. The specific tools you’ll need will depend on the design of your mower’s recoil starter.
What if I’m not comfortable recoiling the pull cord myself?
If you’re not comfortable performing this task, it’s always best to take your lawnmower to a qualified mechanic. They’ll be able to safely recoil the pull cord and ensure that it’s properly adjusted. They can also inspect your mower for any other issues that may be affecting its performance.
What can I do to prevent the pull cord from stretching or wearing out?
You can help extend the lifespan of your pull cord by maintaining it properly. Avoid pulling the cord forcefully, and make sure that the recoil starter mechanism is lubricated as needed. Be sure to store your lawnmower in a clean and dry place to prevent rust and corrosion.
