In a nutshell, there are several reasons why you can’t pull the lawn mower cord. The most common include a tangled pull cord, a stuck recoil spring, a worn-out starter rope, or a problem with the engine itself.
Common Reasons Why Your Lawn Mower Pull Cord Won’t Pull
1. Tangled Pull Cord
The most straightforward reason for a stuck pull cord is a simple tangle. The cord can become knotted within its housing, preventing it from pulling freely.
Solution:
- Inspect the cord: Carefully inspect the pull cord for any knots or tangles. You might need to use a small tool like a pair of pliers to gently disentangle the cord.
- Release the tension: If the cord is tangled, you might need to release the tension on the recoil spring. This is usually done by loosening a screw or nut located on the recoil housing. Once the tension is released, you can carefully untangle the cord.
2. Stuck Recoil Spring
The recoil spring is responsible for storing energy and retracting the pull cord. If this spring becomes stuck or jammed, it can prevent the cord from pulling.
Solution:
- Check for obstructions: Examine the recoil housing for any debris or obstructions that might be preventing the spring from moving freely. Use a small brush or compressed air to clear out any blockage.
- Lubricate the spring: Apply a few drops of light oil to the recoil spring to reduce friction. This can help to free up a stuck spring.
- Replace the spring: If the spring is severely damaged or worn out, it will need to be replaced. You can purchase a replacement spring online or at your local hardware store.
3. Worn-Out Starter Rope
The starter rope is the part of the pull cord that you actually pull. Over time, it can become frayed, worn, or even broken.
Solution:
- Inspect the rope: Examine the starter rope for any signs of wear or damage. If it’s frayed or broken, it needs to be replaced.
- Replace the rope: You can purchase a replacement starter rope at most hardware stores or online. Make sure to get a rope that is the correct length and diameter for your mower model.
- Properly install the new rope: Most starter ropes have a knot at one end. This knot should be inserted into the recoil housing before the rope is threaded through the starter mechanism.
4. Engine Problems
While the problem might seem related to the pull cord, the culprit could be a deeper issue with the engine itself.
H4: 1. Seized Engine:
This occurs when the engine’s internal components become stuck due to lack of lubrication or other issues.
- Solution:
- Try to manually rotate the crankshaft: Try to manually rotate the crankshaft using a wrench or socket. If the engine is seized, you’ll feel significant resistance.

- Professional repair: If you suspect a seized engine, it’s best to seek professional help.
H4: 2. Defective Spark Plug:
A faulty spark plug can prevent the engine from starting, making the pull cord seem stuck.
- Solution:
- Inspect the spark plug: Remove the spark plug and visually inspect it for signs of damage or carbon buildup.
- Replace the spark plug: If the spark plug is faulty, replace it with a new one that matches your mower’s specifications.
- Gap the spark plug: Ensure the spark plug gap is set to the manufacturer’s recommendation.
H4: 3. Fuel Issues:
Problems with fuel delivery, such as clogged fuel lines or a bad fuel filter, can also hinder engine start-up, making the pull cord feel stuck.
- Solution:
- Check the fuel lines and filter: Inspect the fuel lines for any cracks, kinks, or clogs. Replace the fuel filter if it is dirty or damaged.
- Flush the fuel system: If you suspect fuel system contamination, you may need to flush the system with a fuel system cleaner.
Troubleshooting Tips for a Stuck Pull Cord
- Check the spark plug: Before you start troubleshooting, ensure the spark plug is connected and in good condition. A spark test will determine if the spark plug is working correctly.
- Inspect the fuel line and filter: Check for any blockage or damage to the fuel line and ensure the fuel filter is clean.
- Inspect the air filter: A clogged air filter can restrict airflow to the engine, preventing it from starting.
- Don’t force it: If the pull cord feels unusually stiff, don’t force it. Pushing too hard could damage the recoil mechanism.
When to Seek Professional Help
While many pull cord issues can be resolved with DIY solutions, it’s best to call in a professional for more complex problems:
- Seized engine: If you suspect a seized engine, it’s best to have a mechanic diagnose and repair the issue.
- Damaged recoil housing: If the recoil housing is cracked or broken, it will need to be replaced.
- Complex internal engine problems: If you’re not comfortable working on the engine, it’s best to let a professional handle it.
Maintaining Your Lawn Mower
Regular maintenance is crucial for preventing pull cord problems and ensuring your lawn mower runs smoothly.
- Change the oil regularly: This ensures the engine is properly lubricated and prevents wear and tear.
