The dreaded snap. You pull the cord, and instead of the satisfying “thunk” of the engine starting, you hear a sickening pop and feel the cord slip right through your hand. This means your lawn mower’s pull cord has given up the ghost, leaving you stranded in the middle of a burgeoning jungle of grass. Don’t despair! Replacing a pull cord is a surprisingly simple repair that even a novice can tackle. In this comprehensive guide, we’ll walk you through the entire process, from identifying the problem to putting everything back together, ensuring you’ll be back to mowing in no time.
A Quick Overview
Replacing a lawn mower pull cord is a DIY project that involves removing the old cord, attaching the new one, and reinstalling the recoil assembly. The process involves a few simple steps, typically requiring only basic tools and a bit of patience.
Identifying the Issue
Before diving into the replacement process, it’s important to confirm that the problem truly lies with the pull cord and not with something else. Here’s how to isolate the issue:
1. Check for Obvious Damage
- Visual Inspection: Look closely at the pull cord. Is it frayed, broken, or missing a section? If so, the cord itself is likely the culprit.
- Recoil Spring: If the cord is intact, examine the recoil spring, located within the recoil housing. A broken or worn-out spring can also prevent the cord from pulling back properly.
2. Test the Engine
- Manual Start: If the cord feels loose or unresponsive, try manually turning the engine’s crankshaft by using the blade’s nut or a socket wrench. If the engine turns over smoothly, the problem is likely with the pull cord assembly.
- Fuel and Spark: Ensure the lawn mower has enough fuel and that the spark plug is functioning correctly. A lack of spark or fuel can also prevent the engine from starting.
If these checks confirm that the pull cord is the culprit, you’re ready to move on to the replacement process.
Gathering Your Tools and Supplies
Before starting the repair, ensure you have the following tools and materials at hand:
- New Pull Cord: Purchase a replacement cord specifically designed for your lawn mower model.
- Screwdriver: A Phillips head screwdriver is typically needed for removing screws.
- Wrench: A socket wrench or adjustable wrench might be required for removing the recoil housing depending on the mower model.
- Gloves: Protect your hands from potential cuts or scrapes.
- Safety Glasses: Protect your eyes from flying debris.
Step-by-Step Guide to Replacing the Pull Cord
Now, let’s get into the nitty-gritty of the pull cord replacement process:
1. Disconnect the Spark Plug
Safety first! Disconnect the spark plug wire from the spark plug to prevent accidental ignition while working on the engine.
2. Remove the Recoil Housing
- Locate the Recoil Housing: The recoil housing is usually located on the engine’s top or side. It’s typically a round or oval-shaped cover with a handle attached.
- Remove Screws: Use the screwdriver to remove the screws holding the recoil housing in place. The number of screws varies depending on the mower model.
- Detach the Housing: Carefully lift the recoil housing off the engine, taking care not to damage any surrounding parts.
3. Remove the Old Pull Cord
- Identify the Cord Attachment: The pull cord will be attached to the recoil assembly, which is housed within the housing you just removed. You’ll see the cord connected to a small hook or spring-loaded pin.
- Release the Cord: Carefully detach the cord from the attachment point.
4. Attach the New Pull Cord
- Matching the Attachment: The new pull cord will come with a similar attachment point.
- Secure the Cord: Attach the new pull cord to the recoil assembly using the hook or pin.
5. Reinstall the Recoil Housing
- Reverse the Process: Carefully align the recoil housing back onto the engine, making sure the screws line up correctly.
- Tighten the Screws: Use the screwdriver to tighten the screws, ensuring a secure fit.
6. Reconnect the Spark Plug
- Reconnect the Wire: Connect the spark plug wire back to the spark plug.
7. Test the Pull Cord
- First Pull: Give the new pull cord a few gentle pulls to ensure it’s functioning properly.
- Start the Engine: Once you’re satisfied with the cord’s operation, try starting the engine. If it starts without any issues, your replacement is complete.
Troubleshooting and Maintenance
If you encounter any difficulties during the replacement process or if the engine still won’t start, here are some potential troubleshooting tips:
- Check for Proper Attachment: Ensure the new pull cord is securely attached to the recoil assembly.
- Recoil Spring Tension: The recoil spring should be taut enough to pull the cord back in properly. If the spring is weak, it might need replacement.
- Engine Issues: If the engine still won’t start, the problem might be unrelated to the pull cord. Check the fuel supply, spark plug, and other engine components.
Preventative Maintenance:
- Regular Inspections: Check the pull cord for wear and tear periodically.
- Keep It Clean: Clean the recoil assembly and surrounding areas to prevent dust and debris buildup.
- Lubrication: Apply a small amount of lubricant to the recoil spring and other moving parts to reduce friction.

Q2: What are the dangers of using a lawn mower with a broken pull cord?
A broken pull cord can lead to a variety of problems, including injury. If the cord breaks while you’re pulling it, you could be thrown off balance or even injured by the moving parts of the mower. Additionally, a broken cord can make it difficult or impossible to start the mower, which can be frustrating and time-consuming. It’s best to replace a worn cord before it breaks to avoid any potential accidents or delays.
