The sun is shining, the birds are singing, and you’re ready to tackle your lawn. But as you reach for the lawnmower cord, you hear a familiar, frustrating click – nothing. The cord won’t pull! This seemingly simple issue can quickly derail your mowing plans, leaving you wondering what went wrong.
This article dives into the common culprits behind a stubborn lawnmower cord, offering a step-by-step guide to troubleshooting and fixing the problem. We’ll explore the various potential causes, from simple fixes like a clogged recoil spring to more complex issues that may require professional attention.
A Quick Overview:
The most common reason why your lawnmower cord won’t pull is a problem with the recoil system. The recoil system, which consists of a spring, a rope, and a mechanism to retract the rope, is responsible for starting the mower’s engine. When the spring is worn out, broken, or clogged, it can prevent the cord from pulling. However, other factors can also cause this issue, such as a damaged starter or a problem with the engine itself.
Understanding the Recoil System
The recoil system is the heart of your lawnmower’s starting mechanism. It’s designed to transfer the energy from a pulled cord to a spinning flywheel, ultimately cranking the engine.
How Does it Work?
- Pulling the Cord: When you pull the cord, you wind up the recoil spring inside the housing.
- Spring Release: As the cord reaches the end of its pull, a mechanism releases the spring.
- Engine Engagement: The spring’s sudden release rotates the flywheel, which is connected to the engine’s crankshaft.
- Engine Start: The spinning flywheel engages the engine’s internal components, starting the combustion process.
Troubleshooting the Recoil System
If your lawnmower cord won’t pull, the problem likely lies within the recoil system. Here’s how to diagnose the issue:
1. Inspect the Recoil Housing
- Check for Obstructions: Look for any debris, grass clippings, or other foreign objects that might be interfering with the cord’s movement. Use a small brush or a vacuum cleaner to remove any obstructions.
- Examine the Recoil Spring: With the cord fully retracted, try to pull it slightly. If it feels tight or doesn’t move easily, the recoil spring might be worn out or stuck.
- Check the Rope: Ensure the rope is intact and not frayed or broken. A damaged rope will not be able to properly engage the recoil mechanism.
2. Testing the Spring Tension
- Hold the Cord: Grasp the cord firmly about halfway down its length.
- Pull and Release: Pull the cord a short distance and then release it quickly.
- Observe the Spring: If the cord recoils with force and returns to its starting position, the spring is likely in good condition. If it recoils weakly or doesn’t return at all, the spring might be worn or broken.
3. Lubricating the Recoil Mechanism
- Apply Lubricant: Use a light, general-purpose lubricant like WD-40 or a specialized recoil spring lubricant. Spray the lubricant into the recoil housing around the spring and the cord’s path.
- Rotate the Cord: Pull the cord a few times to distribute the lubricant.
Beyond the Recoil System
While the recoil system is the most common culprit, other factors can prevent your lawnmower cord from pulling:
1. Damaged Starter
- Inspect the Starter: The starter is a small, electric motor that engages the flywheel when you turn the key. If the starter is damaged, it might not be able to spin the flywheel, preventing the cord from pulling.
- Test the Starter: Try to start the mower by using the electric start button. If the starter clicks but doesn’t turn the engine, it’s likely faulty.
2. Engine Problems
- Check for Compression: Low engine compression can make it difficult or impossible to start the mower. This might prevent the cord from pulling because the engine isn’t receiving enough force to engage.
- Inspect the Spark Plug: A fouled or damaged spark plug can hinder engine ignition. A spark plug tester can help determine if the plug is working properly.
3. Fuel Issues
- Check the Fuel Lines: Ensure that the fuel lines are clear and not clogged.
- Inspect the Fuel Filter: A dirty fuel filter can restrict fuel flow to the engine, preventing it from starting.
When to Call a Professional
If you’ve checked all of the above and your lawnmower cord still won’t pull, it’s time to call a professional mechanic. Here are some situations where it’s best to leave the repairs to an expert:
- Engine Damage: If you suspect engine damage, such as a broken piston or a damaged crankshaft, it’s best to consult a professional.
- Complex Electrical Issues: If you’re not comfortable working with electrical components, it’s best to avoid attempting repairs on the starter or other electrical parts.
- Extensive Repairs: If the problem requires a complete overhaul of the recoil system or other significant repairs, it’s often more cost-effective to seek professional help.
Tips for Preventing Future Issues
- Regular Maintenance: Perform routine maintenance on your lawnmower, including cleaning the recoil housing, lubricating the spring, and checking the starter.
- Use High-Quality Fuel: Use fresh, clean gasoline to prevent fuel issues.
- Store Properly: Store your lawnmower in a dry, clean place to minimize the risk of corrosion and damage.
Conclusion
A stubborn lawnmower cord can be a frustrating obstacle, but with a little patience and troubleshooting, you can often get it working again. By understanding the recoil system and the other factors that can cause this issue, you’re equipped to diagnose and fix the problem yourself. Remember, if you’re unsure or the issue seems complex, don’t hesitate to seek professional help.
FAQ
Here are 7 FAQs with answers about why your lawn mower cord won’t pull:
1. What could be causing my lawn mower cord to not pull?
There are a few reasons why your lawn mower cord might not be pulling. The most common culprits are a broken or worn-out recoil spring, a clogged or jammed starter assembly, a damaged starter rope, or a seized engine. If the cord feels loose or floppy, it’s likely that the recoil spring has lost its tension. If the cord feels stiff or stuck, the starter assembly might be clogged or jammed. If the cord is frayed or broken, you’ll need to replace it. And if the engine is seized, you’ll need to address that issue before you can start the mower.
2. How can I tell if the recoil spring is broken?
To check if the recoil spring is broken, you’ll need to remove the starter cover. This will allow you to access the recoil spring. If the spring is broken, it will be obvious. The spring will either be completely broken or it will be missing coils. If you’re not comfortable working on your lawn mower, it’s best to take it to a qualified mechanic.
3. How do I clean the starter assembly?
To clean the starter assembly, you’ll need to remove it from the lawn mower. Once the assembly is removed, you can clean it with a brush and some compressed air. Be sure to remove any debris or dirt that you find. Once the assembly is clean, you can reassemble it and try starting the mower again.
4. How do I replace the starter rope?
To replace the starter rope, you’ll need to remove the starter cover. This will allow you to access the starter rope. Once the rope is removed, you can thread the new rope through the starter assembly. Be sure to follow the instructions that came with the new rope. Once the rope is installed, you can reassemble the starter cover.
5. How can I tell if the engine is seized?
A seized engine will feel very stiff when you try to turn the crankshaft. If the engine is seized, you’ll need to take it to a qualified mechanic to have it repaired.
6. Can I fix a seized engine myself?
It is possible to fix a seized engine yourself, but it is a difficult and time-consuming process. If you are not comfortable working on your lawn mower, it is best to take it to a qualified mechanic.
7. What are some tips for preventing my lawn mower cord from not pulling?
To prevent your lawn mower cord from not pulling, you should regularly maintain the starter assembly. Clean the assembly regularly and check the recoil spring for wear and tear. If the spring is worn out, replace it. You should also store your lawn mower in a dry place to prevent rust and corrosion.
