The sun is shining, the grass is growing, and you’re ready to tackle your lawn. But when you pull the cord on your trusty lawn mower, it just… doesn’t start. You pull and pull, but all you hear is a faint click or nothing at all. The dreaded “broken pull cord” scenario. This article will guide you through diagnosing the problem, replacing the cord, and potentially preventing future issues. We’ll cover everything from common signs of a broken cord to detailed instructions on how to repair it yourself, saving you time, money, and frustration.
Understanding the Issue
The pull cord on a lawnmower is responsible for transmitting power from the user to the engine. This power activates the starter mechanism, which in turn ignites the spark plug, allowing the engine to run. When the pull cord breaks, it’s typically due to wear and tear, improper use, or damage from external factors.
Signs of a Broken Pull Cord
- No resistance: When you pull the cord, it feels loose and offers no resistance.
- The cord snaps: You hear a distinct snap or a loud pop as you pull the cord.
- The cord unravels: The cord starts to unravel or fray, making it impossible to pull.
- The engine doesn’t start: The engine doesn’t start even after repeated pulls, and you hear no clicking or cranking sound.
What You’ll Need to Fix Your Lawn Mower Pull Cord
Before you start, gather the following tools and materials:
- New pull cord: It’s important to get a new pull cord that’s specifically designed for your lawn mower model.
- Phillips screwdriver: For removing screws and accessing the recoil housing.
- Needle-nose pliers: For working with the cord and securing it to the starter mechanism.
- Scissors or wire cutters: For trimming excess cord.
- A small flat-head screwdriver: For prying the recoil housing apart.

Frequently Asked Questions
1. What are the signs of a broken lawn mower pull cord?
If your lawn mower pull cord is broken, you’ll notice a few key signs. The most obvious is that the cord will not recoil back into the housing after pulling. Additionally, the engine may not start, as the cord is responsible for activating the starter mechanism. If you hear a loud snapping sound when pulling the cord, this is a strong indication of a broken cord.
You might also notice fraying, tearing, or excessive wear on the cord. These issues can lead to a complete break, so it’s important to address them as soon as possible. If you suspect a broken pull cord, it’s crucial to stop using the lawn mower and address the problem before any further damage occurs.
2. What tools do I need to fix a broken lawn mower pull cord?
You will need a few basic tools to fix a broken lawn mower pull cord. The most essential is a new pull cord, which you can usually find at your local hardware store or online. Additionally, you’ll need a pair of pliers or wire cutters to cut the old cord and a small screwdriver to remove the pull cord housing.
It’s also helpful to have a pair of gloves to protect your hands from sharp edges. By gathering these simple tools, you’ll be well-equipped to tackle the task of replacing a broken pull cord.
3. Can I use a different type of cord for my lawn mower?
While it may seem tempting to use an alternative cord, it’s generally not recommended. Different cords are designed for specific purposes and using the wrong type can lead to malfunctions. It’s best to stick with a replacement cord that’s specifically made for lawn mowers.
This ensures proper fit and compatibility with the starter mechanism. If you’re unsure about the correct type of cord, consult your lawn mower manual or reach out to the manufacturer for guidance.
4. Can I repair a broken pull cord instead of replacing it?
While it’s possible to repair a slightly damaged cord, it’s usually more practical to replace the entire cord. Repairing a broken cord can be difficult and may not be a long-term solution.
For example, splicing a broken cord can lead to weak points that may break again quickly. A new pull cord is relatively inexpensive, making it the most efficient and reliable approach to resolving a broken cord.
5. How do I know if the problem is with the pull cord or the starter?
A broken pull cord is typically the culprit when the engine won’t start. However, if the cord is intact, but you still can’t start the engine, then the problem may lie with the starter mechanism itself.
To determine the issue, you can inspect the pull cord for any visible damage, and if the cord is in good condition, you can carefully check the starter mechanism for any signs of wear or damage.
6. Should I attempt to fix the pull cord myself, or should I take it to a professional?
Replacing a broken pull cord is a relatively simple task that can be done by most people with basic DIY skills. However, if you’re uncomfortable with mechanical repairs or if you’re unsure about the process, it’s always best to take your lawn mower to a qualified technician.
They will have the tools and expertise to diagnose and repair the issue efficiently and safely.
7. Can I use a rope instead of a pull cord?
While rope may seem like a suitable substitute for a broken pull cord, it’s not recommended. Rope is not designed for the specific tension and wear and tear required for a lawn mower pull cord.
Using rope could lead to breakage, slipping, or even damage to the starter mechanism. Stick to using a specifically designed pull cord for best results and longevity.
