The roar of a freshly-started lawn mower is a satisfying sound for any homeowner. But what happens when that familiar pull-cord snaps, leaving you stranded with an uncooperative machine? Don’t despair! Installing a new pull cord is a relatively simple DIY project that can save you time and money. In this comprehensive guide, we’ll walk you through the process step-by-step, from identifying the right cord to successfully attaching it.
A Quick Overview
Replacing a broken pull cord involves removing the old cord, attaching the new one to the recoil starter, and then reassembling the entire mechanism. While the specific steps may vary depending on your mower’s model, the general principles remain the same. This guide provides a general outline, but always consult your lawn mower’s manual for specific instructions and illustrations.
Getting Started: Preparation and Tools
Before diving into the replacement process, make sure you have the following items on hand:
- A new pull cord: Measure the length of your old cord and purchase a compatible replacement.
- A screwdriver: Choose a screwdriver that matches the screws holding your mower’s engine cover.
- Wire cutters or pliers: These will help you trim the pull cord to the correct length.
- Work gloves: Protect your hands from potential sharp edges.
- Your lawn mower’s manual: It contains model-specific instructions and diagrams.
Step 1: Disconnecting the Spark Plug
Safety comes first! Disconnect the spark plug wire to prevent accidental starts while you work on the engine. Locate the spark plug, usually on the side of the engine, and gently pull the wire off the plug.
Step 2: Removing the Engine Cover
To access the recoil starter, you’ll need to remove the engine cover. This typically involves a few screws. Consult your manual for specific instructions and use the screwdriver to carefully remove these screws. Once the screws are out, gently lift the engine cover off and set it aside.
Step 3: Detaching the Old Pull Cord
The old pull cord will be connected to the recoil starter, usually by a small clip or spring. Carefully detach the cord from the starter. You may need to use pliers or wire cutters to cut through any remaining cord material if it’s stuck.
Step 4: Attaching the New Pull Cord
Now it’s time to install the new pull cord. Refer to your lawn mower’s manual for the specific placement and attachment method for your model.
- For most mowers: The new cord will have a loop at one end. Slide this loop over the hook or clip on the recoil starter.
- Some models: May require you to thread the new cord through a small hole in the recoil starter.
Step 5: Winding the Cord and Reassembling
Once the new pull cord is securely attached, wind it around the recoil starter.
- Start at the outer edge: Wind the cord around the starter, keeping it tight and even.
- Secure the cord: When you reach the end, use the provided clip or tie to secure the cord to the starter.
After winding the cord, reassemble the engine by placing the engine cover back on and securing it with the screws. Ensure all screws are tight.
Step 6: Reconnecting the Spark Plug
Now that the engine is reassembled, you can reconnect the spark plug wire. Carefully slide the wire back onto the spark plug, ensuring it’s secure.
Step 7: Testing the New Pull Cord
With the spark plug wire reconnected, it’s time to test your new pull cord. Give the cord a few gentle pulls to ensure it’s functioning correctly.
Important Tips and Troubleshooting
- Use the right cord: Always choose a pull cord that’s compatible with your lawn mower. Check the length and material of the original cord to ensure a proper replacement.
- Lubricate the recoil starter: Apply a small amount of lubricant to the recoil starter mechanism to ensure smooth operation.
- Don’t overtighten the screws: Tighten the engine cover screws securely but avoid overtightening, which could damage the engine.
- Troubleshooting: If the new pull cord isn’t working, double-check the following:
- Proper attachment: Ensure the cord is securely attached to the recoil starter.
- Winding tension: Make sure the cord is wound tightly and evenly around the starter.
- Spark plug connection: Verify that the spark plug wire is securely connected.

By following these steps and taking the time to do it right, you’ll get your mower back in action in no time, ready to conquer your lawn.
