Spring is here, and with it comes the joy of maintaining your lush green lawn. However, just like any other piece of machinery, your lawn mower can encounter problems, and one common issue is a malfunctioning spring. From the recoil spring to the blade engagement spring, these essential components are crucial for smooth operation. This article will guide you through the process of diagnosing and fixing a broken spring on your lawn mower, saving you time, money, and frustration.
A broken spring in your lawn mower can manifest in several ways. You might experience difficulty starting the engine, the blade might not engage properly, or the mower might be difficult to maneuver. Identifying the specific spring causing the issue is crucial for successful troubleshooting and repair.
Identifying the Culprit: Which Spring Is Giving You Trouble?
To tackle the problem head-on, you need to pinpoint the exact spring that’s causing the issue. Here’s a breakdown of common lawn mower springs and their roles:
1. Recoil Spring:
This spring is responsible for retracting the starter rope after you pull it, enabling the engine to crank and start. A broken or weakened recoil spring can prevent the starter rope from retracting smoothly, making starting the engine a strenuous task.
Symptoms of a Broken Recoil Spring:
- Difficulty pulling the starter rope.
- The starter rope doesn’t retract properly.
- A loud “clunk” or “bang” sound when pulling the starter rope.
2. Blade Engagement Spring:
This spring is essential for engaging and disengaging the mower blade. A broken blade engagement spring will prevent the blade from rotating properly, hindering your lawn mowing efforts.
Symptoms of a Broken Blade Engagement Spring:
- The blade does not spin when the engine is running.
- The blade engages and disengages inconsistently.
- The blade spins uncontrollably when the engine is stopped.
3. Other Springs:
While the recoil and blade engagement springs are the most common culprits, other springs within your lawn mower can also malfunction. These include springs that:
- Control the height adjustment lever.
- Maintain tension on the drive system.
- Support the deck of the mower.
Identifying these springs requires careful inspection of your mower and its components.
Troubleshooting a Broken Spring: The “How-To”
Now that you’ve identified the problematic spring, let’s dive into the troubleshooting process:
1. Safety First:
Before you begin working on your lawn mower, always disconnect the spark plug wire to prevent accidental starting. Additionally, wear protective gear such as gloves and safety glasses.
2. Locate the Spring:
Identify the spring that needs attention. It’s often located in a visible area of the mower deck or engine housing. If the spring is hidden, refer to your mower’s user manual for detailed diagrams and instructions.
3. Inspect the Spring:
Examine the spring for any signs of damage. Look for cracks, breaks, or worn-out sections. If the spring is visibly broken or heavily corroded, it needs to be replaced.
4. Measure the Spring:
If you are replacing the spring, take accurate measurements of the old one before removing it. These measurements include:
- Length: The distance between the ends of the spring when it’s fully extended.
- Wire Diameter: The thickness of the spring wire.
- Inside Diameter: The diameter of the spring’s coil.
- Number of Coils: The number of individual coils in the spring.
This information will help you find a compatible replacement spring from your local hardware store or online retailer.
5. Remove the Broken Spring:
Carefully remove the broken spring from the mower. Depending on the location and type of spring, you might need to use pliers, screwdrivers, or other tools. Consult your mower’s manual for specific instructions for removing the spring.
6. Install the New Spring:
Once you have a new spring, install it in the same location as the old one. Make sure to align the spring correctly and securely fasten it to the mower’s components.
7. Test the Mower:
After installing the new spring, reconnect the spark plug wire and start the engine. Test the mower’s functionality to ensure the spring is correctly installed and working properly.
Don’t Neglect Regular Maintenance
Regular maintenance can significantly prevent spring problems and ensure your lawn mower operates smoothly. This includes:
- Cleaning: Clean the underside of the mower deck, remove grass clippings, and lubricate moving parts regularly.
- Inspecting: Inspect the springs periodically for signs of wear or damage.
- Replacing: Replace springs before they break completely to prevent potential damage to other components.
When to Seek Professional Help
While most lawn mower spring repairs can be done at home, some situations may require professional assistance. If you encounter:
- Severe damage to the spring or other mower components.
- Difficulty identifying the specific spring causing the problem.
- Lack of confidence in your repair skills.
Seeking professional assistance from a qualified mechanic is advisable.

Frequently Asked Questions
What are the common signs that my lawn mower spring is out of order?
The most obvious sign is that your lawn mower won’t start or won’t stay running. This is because the spring is responsible for returning the engine’s recoil to its starting position, and if it’s broken, the engine won’t be able to crank. You might also hear a clicking or clunking sound when you try to start the mower, which is another sign of a broken spring.
Additionally, if the spring is stretched or worn out, it might not be providing enough tension to properly start the engine. This can lead to difficulty starting the mower, or the engine might stall after a few seconds. If you notice any of these problems, it’s best to check your lawn mower’s spring and replace it if necessary.
How do I know if my lawn mower spring is broken?
There are a few ways to check if your lawn mower spring is broken. First, you can visually inspect the spring for any signs of damage, such as cracks, breaks, or rust. If the spring looks damaged, it’s likely broken. You can also test the spring by pulling on it gently. If it doesn’t spring back into place, it’s also likely broken.
If you’re not sure if your spring is broken, you can take your mower to a qualified mechanic to have it inspected. They will be able to determine if the spring needs to be replaced.
How do I replace my lawn mower spring?
Replacing a lawn mower spring is a relatively simple process that can be done with a few basic tools. You will need a screwdriver, a wrench, and a new spring. First, disconnect the spark plug to prevent accidental starting. Then, remove the recoil housing by unscrewing the screws holding it in place. Once the housing is removed, you can access the spring.
Remove the old spring by carefully pulling it out of the housing. Be careful not to lose any small parts. Once the old spring is removed, you can install the new spring by inserting it into the housing and attaching it to the recoil mechanism. Reassemble the recoil housing and reconnect the spark plug.
How often should I replace my lawn mower spring?
The lifespan of a lawn mower spring depends on the quality of the spring and how often you use the mower. However, it’s a good idea to inspect the spring at least once a year for signs of wear and tear. If the spring is showing signs of damage or is becoming less effective, you should replace it.
Regular maintenance is key to keeping your lawn mower in good working order, and replacing the spring when necessary is an important part of that process.
What happens if I don’t replace a broken lawn mower spring?
If you don’t replace a broken lawn mower spring, you’ll likely not be able to start your mower at all. This is because the spring is essential for returning the engine to its starting position, and without it, the engine won’t be able to crank.
Even if you manage to start the mower, a broken spring could lead to other problems, such as engine damage or a fire hazard. Therefore, it’s important to replace a broken spring as soon as possible.
Can I use any type of spring to replace my lawn mower spring?
No, you can’t use any type of spring to replace your lawn mower spring. The spring needs to be the correct size and tension for your specific model of lawn mower. If you use a spring that’s too weak or too strong, it could damage your mower or cause it to malfunction.
Always consult your lawn mower’s manual or contact the manufacturer for information on the correct spring type for your model.
