There’s nothing quite like the feeling of a perfectly manicured lawn, but that sense of accomplishment can quickly turn to frustration when your lawn mower refuses to cooperate. One of the most common frustrations is a lawn mower cord that simply won’t pull. Whether you’re dealing with a stubborn electric start or a recoil that feels like it’s stuck in neutral, this article will guide you through the potential culprits and provide practical solutions to get your mower back in action. We’ll explore common causes, troubleshooting tips, and even offer a few preventative measures to keep your mower running smoothly in the future.
The short answer is that a lawn mower cord won’t pull for several reasons, including a tangled or worn-out cord, a faulty recoil spring, a jammed engine, or a lack of proper tension in the recoil system. Diagnosing the specific problem requires a step-by-step inspection process, which we’ll cover in detail in this article.
The Great Cord Pull Mystery: Where to Start
The first step to solving the “won’t pull” problem is to pinpoint the source of the issue. It’s tempting to immediately jump into repairs, but a methodical approach will save you time and potential frustration. Here’s how to approach the diagnosis:
1. Visual Inspection:
Examine the Cord: Look for any visible damage like cuts, fraying, or excessive wear and tear. A damaged cord can prevent the recoil system from functioning correctly.
* Check for Tangling: The cord can become entangled within the housing or with other components. Carefully untangle any knots or twists.
* Inspect the Recoil Assembly:* The recoil assembly houses the spring and the mechanism that pulls the cord. Look for any visible damage, wear, or signs of excessive rust.
2. Testing the Recoil:
* Engage the Recoil: Try pulling the cord gently, feeling for resistance. If you feel a springy “snap” or a smooth pull, the recoil system is likely functioning properly.
* Listen for Sounds: Pay attention to any clicking or grinding noises. These could indicate a worn-out spring or a problem with the recoil assembly.
3. Investigating the Engine:
* Engine Jams: If you feel excessive resistance when pulling the cord, the engine might be jammed. Try turning the crankshaft by hand (using a wrench if necessary) to see if it’s free to rotate.
Common Culprits and Solutions
Now that you have a better idea of the possible problems, let’s dive into the specific culprits and their solutions:
1. Tangled or Worn-out Cord
H3. Why It Happens: The cord, especially in older mowers, can become tangled within the housing or worn down due to repeated use.

4. Lack of Tension in the Recoil System
H3. Why It Happens: The recoil assembly might lose tension due to:
* Worn-out Parts: The recoil pawls, which engage with the recoil spring, can wear down over time.
* Improper Installation: The recoil assembly might have been incorrectly installed during previous repairs or maintenance.
H4. The Fix:
* Adjust Tension: Some lawn mowers have adjustable tension screws on the recoil assembly. Refer to your mower’s manual to locate and adjust these screws for optimal tension.
* Replace Recoil Assembly: If the tension adjustment doesn’t solve the problem, the recoil assembly itself might be worn out and need replacement.
5. Other Possible Issues
While the most common culprits have been discussed, a few other issues could cause your cord to not pull.
H3. Damaged or Worn-out Parts:
* Clutch Assembly: A worn-out or malfunctioning clutch can prevent the engine from engaging.
* Flywheel: The flywheel may be damaged or worn down.
H3. Environmental Factors:
* Extreme Temperatures: Extremely cold or hot temperatures can affect the performance of the recoil system.
H4. The Fix:
* Repair or Replace: Damaged parts should be repaired or replaced by a qualified mechanic.
* Adjust to Environment: If environmental factors are the culprit, you may need to wait for more favorable temperatures or consider using a different type of lawn mower.
