A broken pull cord can be a major inconvenience, leaving you with a lawn that’s overgrown and a sense of frustration. But don’t despair! Replacing a pull cord is a relatively simple task that most homeowners can tackle themselves.
This article will guide you through the process of putting a pull cord on a lawnmower, step by step. We’ll cover everything from identifying the right replacement cord to understanding the different types of pull cord systems. By the time you’re done reading, you’ll be equipped with the knowledge and confidence to fix your lawnmower and get back to enjoying a perfectly manicured lawn.
A Brief Overview
The pull cord on a lawnmower is a vital component that allows you to start the engine. It’s connected to a recoil starter mechanism, which in turn engages the flywheel and ignites the spark plug. When the pull cord breaks, it disrupts this chain of events, making it impossible to start the mower. Replacing the pull cord involves removing the old one, installing the new one, and ensuring proper tension and alignment.
Identifying the Right Replacement Cord
Before you embark on replacing the pull cord, the first step is to identify the correct replacement part. This seems obvious, but a quick and simple check will save you a lot of frustration later.
Understanding Different Types of Pull Cord Systems
Not all pull cord systems are created equal. There are two primary types:
1. Single-Cable System: This is the most common type and consists of a single cable that runs from the handle to the recoil starter. The cable is typically made of nylon or steel, and it’s connected to a spring-loaded mechanism within the starter.
2. Dual-Cable System: In this type of system, there are two cables running to the recoil starter. One cable is used for pulling, while the second cable acts as a return spring. This system is often found on heavier-duty lawnmowers.
3. Identifying Your Type: Take a close look at the pull cord system on your mower. Does it have one or two cables? This will help you identify the appropriate replacement part.
Measuring the Pull Cord
After you’ve determined the type of system you have, you need to measure the length of the existing pull cord. This is crucial to ensure that you purchase a replacement cord that is the right size.
1. Disconnect the Old Pull Cord: Before measuring, you’ll need to disconnect the old pull cord from the recoil starter. You may have to remove the handle or some other components to access the cord.
2. Measure the Length: Once the cord is disconnected, use a tape measure to determine its length. Measure from the end of the cord where it attaches to the handle to the point where it connects to the recoil starter.
3. Ordering the Replacement Cord: With the type of system and the length of the cord in hand, you can order a replacement from your local hardware store, an online retailer, or a lawnmower repair shop.
Replacing the Pull Cord: A Step-by-Step Guide
With the right replacement cord in hand, you’re ready to tackle the repair. Follow these steps to ensure a successful installation:
1. Preparing the Lawn Mower
- Disconnect the spark plug: Safety first! Disconnect the spark plug wire from the spark plug to prevent accidental starting. This will also help you avoid any electrical shocks.
- Remove the handle: You’ll need to remove the handle to access the pull cord mechanism. The handle is typically held in place by screws or bolts.
- Locate the pull cord assembly: Once the handle is removed, you’ll see the pull cord assembly, which includes the recoil starter and the pull cord.
2. Removing the Old Pull Cord
- Release the tension: The old pull cord will be under tension. Locate the tension adjustment screw or nut and loosen it. This will release the tension on the cord and make it easier to remove.
- Disconnect the cord: Unhook the old pull cord from the recoil starter. This may involve a simple clip or a more complex mechanism.
- Remove the cord from the handle: Slide the old cord out of the handle.
3. Installing the New Pull Cord
- Attach the cord to the handle: Thread the new pull cord through the handle. If there’s a special attachment mechanism, make sure the new cord fits securely.
- Attach the cord to the recoil starter: Connect the new pull cord to the recoil starter. Again, make sure it’s securely attached, using the appropriate clip or mechanism.
- Adjust the tension: Tighten the tension adjustment screw or nut to provide the correct amount of tension on the cord. Too much tension can make it difficult to pull, while too little tension can cause the cord to slip.
4. Testing and Reassembly
- Test the pull cord: Before reassembling the lawnmower, give the pull cord a few test pulls to ensure it’s operating properly. Make sure it pulls smoothly and the recoil mechanism is working correctly.
- Reassemble the lawnmower: Reattach the handle and tighten all screws and bolts. Reconnect the spark plug wire.
5. Final Touches
- Dispose of the old pull cord properly: Dispose of the old pull cord responsibly. It’s best to recycle it if possible.
- Enjoy your repaired lawnmower: You’ve successfully replaced the pull cord and your lawnmower is ready to tackle those overgrown patches.
Troubleshooting Common Issues
While replacing a pull cord is generally straightforward, you may encounter some issues:
1. The Recoil Starter Won’t Engage:
- Check the tension: Make sure the pull cord has the correct tension. Too much tension can prevent the recoil starter from engaging.
- Inspect the spring: The spring inside the recoil starter may be broken or worn out. If so, you’ll need to replace the entire recoil starter assembly.
2. The Pull Cord Breaks Again:
- Inspect the cable: The new pull cord may be defective. Ensure it’s properly installed and not frayed or damaged.
- Check the recoil starter: If the recoil starter is worn out, it may cause the pull cord to break prematurely. You may need to replace the entire assembly.
3. The Lawn Mower Still Won’t Start:
- Check the spark plug: A faulty spark plug can prevent the engine from starting. Replace the spark plug if necessary.
- Inspect the fuel system: Ensure the fuel lines are clear and the fuel tank is full.
Tips for Maintaining Your Lawn Mower
Regular maintenance is crucial to keeping your lawnmower in top working condition. Here are a few tips:
1. Clean the Air Filter: A dirty air filter can restrict airflow to the engine, causing it to run poorly. Clean or replace the air filter regularly.
2. Change the Oil: Changing the engine oil regularly helps keep the engine clean and lubricated. Check your owner’s manual for recommended oil change intervals.
3. Inspect the Blades: Sharp blades are essential for a clean cut. Sharpen or replace the blades as needed.
Conclusion
Replacing a pull cord is a relatively simple repair that most homeowners can tackle themselves. By following the steps outlined in this guide, you can confidently fix your lawnmower and get back to enjoying a well-maintained lawn. Remember to use caution, wear safety glasses, and always disconnect the spark plug before working on any lawnmower component. With a little patience and the right tools, you can overcome this common lawnmower issue and keep your lawn looking its best.
