The sound of a lawn mower struggling to start can be a frustrating and even ominous sound, especially when you’re in the middle of a weekend yard work session. If your Toro lawn mower is refusing to cooperate, one of the most common culprits is a faulty pull cord. Fortunately, fixing a broken pull cord is often a straightforward DIY repair that can save you a trip to the repair shop. In this comprehensive guide, we’ll walk you through the steps on how to identify a broken pull cord, diagnose the problem, and get your Toro lawn mower back in action.
The Basics of a Pull Cord
A pull cord is a vital component in the starting mechanism of your lawn mower. It’s a simple but effective system that uses a cord and a spring to engage the engine. When you pull the cord, you wind the spring, and the stored energy from the spring is then used to rotate the engine crankshaft, ultimately starting the engine.
Here’s a quick overview of the most common problems with Toro lawn mower pull cords:
- The cord is frayed or broken: This is the most obvious problem, and it usually makes itself known by a snapping sound when you pull the cord.
- The spring is worn out: A worn-out spring won’t have enough power to start the engine. You might notice the cord pulls easily but the engine doesn’t start.
- The cord is stuck in the recoil housing: This could happen due to debris or a build-up of dirt and grime in the housing.
H2: Diagnosing a Pull Cord Problem
Before you dive into replacing the pull cord, it’s crucial to correctly identify the source of the problem. Here’s a step-by-step guide to help you diagnose your Toro lawn mower’s pull cord issue:
H3: Inspecting the Pull Cord
- Check for visual damage: Examine the pull cord for any signs of fraying, tearing, or breakage. If the cord looks damaged, it’s likely the culprit.
- Pull the cord and listen: Pull the cord gently a few times and listen for any snapping sounds. A snapping sound often indicates a broken cord.
- Look for signs of a stuck cord: If the cord feels stuck or doesn’t move freely, there could be an obstruction in the recoil housing.
H3: Testing the Spring
- Disconnect the spark plug: Safety first! Disconnect the spark plug wire to prevent accidental starting.
- Pull the cord several times: Listen for the “click” or “whirr” of the spring engaging. If you don’t hear this sound or the cord pulls easily with no resistance, the spring might be worn out.
H2: Replacing the Pull Cord
Now that you’ve diagnosed the problem, it’s time to replace the pull cord. Here’s a step-by-step guide on how to do it:
H3: Gathering Your Tools
- Replacement pull cord: Make sure to get a pull cord that’s specifically designed for your Toro model.
- Screwdriver: You’ll need a screwdriver that fits the screws on the recoil housing.
- Pliers: A pair of pliers will help you with removing the old cord.
- Gloves: Protecting your hands is always a good idea when working with mechanical parts.
H3: Replacing the Pull Cord
- Remove the recoil housing: Locate the screws holding the recoil housing in place. Use your screwdriver to remove the screws, and carefully lift off the housing.
- Remove the old pull cord: Remove the old cord from the recoil assembly. You may need to use your pliers to help pull it free.
- Install the new pull cord: Feed the new cord through the recoil assembly, making sure it’s properly routed and secured.
- Reattach the recoil housing: Align the recoil housing back in place and secure it with the screws.
- Test the pull cord: Connect the spark plug wire, then pull the cord a few times to ensure the engine starts and the cord operates smoothly.
H2: Troubleshooting and Tips
While replacing the pull cord is often a simple fix, there might be other factors contributing to the problem.
H3: Additional Troubleshooting Steps
- Clean the recoil housing: Accumulated debris can cause the cord to snag or stick. Remove the housing and clean it thoroughly.
- Lubricate the recoil assembly: A few drops of oil on the recoil assembly can help ensure smooth operation and reduce friction.

You may also need a pair of wire cutters to trim the old cord and a lubricant to help with the reassembly process.
Q4: How do I replace the pull cord on a Toro lawn mower?
A: Replacing a pull cord on a Toro lawn mower involves a few steps. First, you’ll need to remove the old cord by releasing the tension on the recoil spring. Then, you can install the new cord by threading it through the recoil assembly and attaching it to the engine crankshaft. Finally, you’ll need to wind the recoil spring and test the new cord to ensure it’s working properly.
Q5: How do I know if the recoil spring is also faulty?
A: If you have a faulty recoil spring, you might notice that the pull cord doesn’t retract smoothly or that the engine doesn’t start easily. The spring might also be visibly broken or worn out.
