Understanding Pull Cords
A pull cord is an essential component of your lawn mower’s starting mechanism. Grasping its function simplifies understanding how to change it, a key task for maintaining your mower.
What Is a Pull Cord?
A pull cord, often found on handheld lawn mowers, connects to the engine’s flywheel. When you pull the cord, it engages the starter, allowing the engine to turn over. This action creates the necessary momentum for starting the mower. If the cord is frayed or broken, the engine won’t start, and you’ll need to replace it.
Importance of a Functional Pull Cord
A functional pull cord is crucial for your lawn mower’s reliability. If the cord snaps or becomes hard to pull, you can’t effortlessly start the engine. A smoothly operating pull cord allows for quick starts and prevents unnecessary frustration. Regularly checking the cord for wear ensures your mower remains ready when you need it. Taking care of this small but vital component keeps your mowing task efficient and hassle-free.

Preparing the Lawn Mower

Removing the Old Pull Cord
- Access the starter cover: Use a screwdriver to remove the screws securing the starter cover. Keep screws in a safe place.
- Take off the starter: Carefully lift the starter assembly out of its housing. This reveals the pull cord mechanism.
- Detach the old cord: Locate the knot holding the old cord in place. Cut the cord near the knot and pull the remainder out of the starter assembly.
- Remove the recoil spring: If it’s necessary, gently unwind the spring. Be cautious, as it may snap back.
Installing the New Pull Cord
- Measure the new cord: Cut a new pull cord to the appropriate length. Use the old cord as a reference, or measure enough to accommodate the starting mechanism.
- Thread the new cord: Insert one end of the new cord through the starter assembly’s hole. Pull enough through for a secure knot.
- Secure the cord: Tie a knot at the end of the cord to secure it in place. Ensure it’s tight and won’t slip.
- Reattach the spring: If removed, carefully wind and reattach the recoil spring. Make sure it’s positioned correctly.
- Reassemble the starter cover: Replace the starter assembly, aligning it properly. Secure it with screws.
- Reconnect the spark plug wire: Attach the wire back to the spark plug to enable starting.
- Test the pull cord: Give the cord a firm pull to check its working condition. If the engine engages smoothly, the installation’s successful. If not, double-check the cord’s installation and tension.
