The gentle hum of a lawnmower, the satisfying scent of freshly cut grass – these are the hallmarks of a well-maintained lawn. But what happens when that familiar hum turns into a strained groan, and the pull cord stubbornly refuses to start your mower? This is often a sign of a worn-out or improperly wound pull cord. Fear not, fellow green thumbs! This comprehensive guide will equip you with the knowledge and skills to tackle this common lawnmower issue with confidence. We’ll walk you through the process of identifying the problem, choosing the right cord, and mastering the art of winding a pull cord – all while ensuring your mower roars back to life in no time.
A Short Overview:
Winding a lawnmower pull cord is a straightforward process that involves replacing a worn or tangled cord with a new one. This involves understanding the different types of cords, knowing how to identify the components, and carefully following the steps for winding the cord onto the recoil spring.
Identifying the Problem: Why is Your Pull Cord Not Working?
Before diving into the winding process, it’s crucial to pinpoint the source of the issue. There are a few common culprits:
1. Worn-Out Pull Cord:
The most obvious reason for a non-functional pull cord is simply wear and tear. Over time, the cord’s fibers can fray, break, or become stretched, hindering its ability to engage the recoil spring.
2. Tangled Pull Cord:
If the cord becomes tangled within the recoil mechanism, it won’t be able to fully extend and pull the starter rope, resulting in a sluggish or unresponsive start.
3. Damaged Recoil Spring:
The recoil spring is responsible for retracting the pull cord. If it’s broken, weakened, or rusted, it won’t provide enough tension to effectively start the engine.
4. Engine Issues:
Sometimes, a non-functional pull cord is a symptom of a deeper problem within the engine itself. A flooded carburetor, a lack of fuel, or a faulty ignition system can prevent the engine from starting, giving the impression that the pull cord is at fault.
Troubleshooting Tips:
- Visual Inspection: Carefully examine the pull cord for any signs of wear, fraying, or tangling.
- Test the Recoil Spring: Pull the cord firmly and release it. The recoil spring should retract the cord smoothly and with a noticeable resistance.
- Engine Check: If the pull cord feels normal, consider troubleshooting any engine-related issues, such as fuel supply or spark plug functionality.
Choosing the Right Pull Cord: Understanding the Options
Not all pull cords are created equal! When replacing your worn-out cord, you need to ensure you’re selecting the correct type for your specific mower. Here’s a breakdown of the key factors:
1. Cord Length:
The length of the cord is crucial for proper operation. A cord that’s too short will make starting the mower difficult, while a cord that’s too long can lead to tangling and even damage to the recoil mechanism.
Tip: Measure the length of your existing cord and look for a replacement with a similar length.
2. Cord Material:
Pull cords are typically made of either nylon or polyester. Nylon cords are generally more durable and resistant to wear, while polyester cords are known for their flexibility.
Tip: Choose a nylon cord if you need a durable option, or opt for polyester if you prefer a more flexible cord.
3. Cord Diameter:
The diameter of the cord, measured in millimeters, determines its thickness. A thicker cord will generally provide more starting power but may be more difficult to wind.
Tip: Choose a cord diameter that matches your existing cord or consult your mower’s manual for the recommended diameter.
