The roar of a lawnmower, the fresh scent of cut grass – it’s a quintessential summer sound and smell. But what happens when that satisfying “vroom” turns into a frustrating “clunk” and your pull cord hangs limply? A broken pull cord can quickly turn your lawn mowing day into a nightmare. Luckily, it’s a common problem with an easy fix. This comprehensive guide will walk you through the steps of repairing a lawnmower pull cord, saving you time, money, and the frustration of a stalled lawn mowing session.
Understanding the Pull Cord System
The pull cord on your lawnmower is a simple but crucial component. It’s designed to transfer the force of your pull to the engine’s crankshaft, starting the engine. The system generally consists of a handle, a cord, a recoil spring, a starter pawl, and a starter housing. When you pull the cord, the recoil spring winds up, and then releases, spinning the starter pawl, which engages the engine crankshaft.
Diagnosing the Problem
Before you start tinkering with your lawnmower, it’s important to correctly diagnose the issue. A broken pull cord can manifest in a few different ways:
- The cord doesn’t retract properly: This is usually a sign of a worn or broken recoil spring.
- The cord feels loose or floppy: This could indicate a problem with the cord itself, or the connection between the cord and the handle.
- The cord snaps: This means the cord has broken and needs replacing.
- The engine doesn’t start even with a good pull: While this could be a pull cord issue, it’s also likely a problem with the engine itself.
Repairing a Broken Pull Cord
Now that you’ve identified the problem, let’s get into the repair process. Here’s a step-by-step guide on how to repair a broken pull cord:
Step 1: Disassembling the Starter Housing
- Remove the spark plug: This is an important safety precaution to prevent accidental starting.
- Locate the starter housing: It’s usually a round or rectangular plastic or metal housing located near the engine.
- Identify the screws holding the housing together: Use a screwdriver to loosen and remove these screws.
- Gently pry off the housing: Be careful not to damage the housing or the parts inside.
Step 2: Examining the Components
- Inspect the pull cord: Look for any tears, fraying, or broken sections.
- Check the recoil spring: Look for signs of wear, rust, or damage.
- Examine the starter pawl: This small metal piece should be intact and not stuck.
- Look for any broken or loose parts: Pay close attention to the connections between the pull cord, handle, and the starter pawl.
Step 3: Replacing the Pull Cord
- Remove the old cord: If the cord is broken, you’ll need to detach it from the handle and the starter housing.
- Install the new cord: Thread the new cord through the starter housing, making sure to follow the proper path.
- Connect the cord to the handle: Securely attach the new cord to the handle using the provided clips or connectors.
- Secure the cord to the starter housing: Make sure the cord is securely attached to the starter housing, often with a small hook or clip.
Step 4: Replacing the Recoil Spring (If Needed)
- Remove the old recoil spring: If the spring is damaged or worn, you’ll need to replace it.
- Install the new recoil spring: Carefully install the new recoil spring in the starter housing, making sure it’s properly seated.
Step 5: Reassembling the Starter Housing
- Replace the starter housing: Carefully position the housing back onto the engine.
- Secure the screws: Tighten the screws that hold the housing together.
- Reinstall the spark plug: Ensure the spark plug is securely tightened.

FAQs
Q1: What are the common signs of a broken pull cord on a lawnmower?
The most obvious sign of a broken pull cord is when the cord feels loose or doesn’t recoil properly. You may notice that it doesn’t pull back smoothly after starting the mower, or it might even slip out of the handle entirely. Another indication is if the mower starts with difficulty, requires multiple pulls, or doesn’t start at all.
These issues are usually caused by a worn or frayed cord, a broken spring, or a loose connection within the pull cord mechanism. Identifying the specific problem will help you determine the best course of action for repairing it.
Q2: Can I replace just the pull cord on my lawnmower?
It is possible to replace just the pull cord on your lawnmower, but it’s not always the most effective solution. If the cord itself is worn, replacing it with a new one will likely fix the issue. However, if the problem lies with the spring or other components, replacing the cord alone might not solve the issue.
In such cases, it’s generally recommended to replace the entire pull cord assembly for a more comprehensive repair. This assembly includes the cord, spring, and other essential parts, ensuring a complete and reliable fix for your lawnmower.
Q3: What tools do I need to repair a pull cord on a lawnmower?
To repair a pull cord on a lawnmower, you will need a few basic tools that are typically found in most home toolboxes. These tools include a screwdriver (Phillips head and flathead), a wrench, pliers, and a pair of wire cutters.
You may also need a new pull cord or pull cord assembly, depending on the extent of the repair. Having a clean workspace, a manual for your lawnmower, and a pair of gloves can also make the repair process easier and safer.
Q4: How do I disconnect the pull cord from the engine?
Before you can replace the pull cord, you need to disconnect it from the engine. This process involves releasing the tension on the cord and detaching it from the starter mechanism. To do this, you’ll need to locate the pull cord release lever, which is usually located on the side of the engine or beneath the recoil housing.
Engage the lever, which will release the tension on the cord and allow you to pull it free from the engine. Be careful not to pull too hard as you might damage the starter mechanism. Once the cord is disconnected, you can safely remove it from the lawnmower.
Q5: How do I replace the pull cord on a lawnmower?
Replacing the pull cord on a lawnmower involves a few simple steps. First, you need to detach the old cord from the engine, as explained earlier. Next, thread the new cord through the guide holes in the recoil housing and connect it to the starter mechanism.
Ensure the cord is properly routed and secured, then test the tension by pulling it back and forth. If the cord feels smooth and recoils properly, you’ve successfully replaced it. Finally, reassemble the pull cord housing and ensure all components are securely fastened.
Q6: What if I can’t find a replacement pull cord for my lawnmower?
If you can’t find a replacement pull cord for your lawnmower, you can try contacting the manufacturer or a local lawnmower repair shop. They may have a cord in stock or can order one for you. Alternatively, you could try finding a compatible pull cord from a third-party seller online.
However, ensure the replacement cord is the correct size and specifications for your lawnmower to ensure proper functionality and safety.
Q7: How can I prevent my pull cord from breaking in the future?
To prevent your pull cord from breaking in the future, it’s essential to maintain it properly. This includes checking the cord for wear and tear regularly, and replacing it as needed. Additionally, avoid pulling the cord too hard or abruptly.
Ensure that the engine is in neutral gear before pulling the cord, and don’t attempt to start the mower if it’s flooded or out of fuel. These precautions can help extend the life of your pull cord and prevent premature wear and tear.
