Have you ever wrestled with a stubborn lawn mower, struggling to get it started? You pull the cord, and it feels like you’re pulling a brick wall. Perhaps the cord snaps, leaving you with a broken lawn mower and a growing patch of unruly grass. Don’t despair! This article will walk you through the simple process of replacing a broken pull string on your lawn mower. We’ll cover everything from identifying the right string to the proper steps for installation, ensuring you can get back to mowing in no time.
Understanding the Pull String
The pull string, also known as the recoil starter rope, is an essential part of your lawn mower’s starting system. It’s connected to a spring-loaded mechanism that rotates the engine crankshaft, giving your mower the initial boost it needs to start. When the string breaks, it can make starting your lawn mower impossible.
Getting Started: Tools and Materials
Before diving into the replacement process, gather the following tools and materials:
- Replacement pull string: Ensure you purchase a string compatible with your lawn mower model.
- Phillips screwdriver: You’ll likely need this to remove the starter housing cover.
- Pliers: These can be handy for gripping the string and making adjustments.
- A pair of gloves: Protect your hands from potential scratches or dirt.
Step-by-Step Guide to Replacing Your Lawn Mower Pull String
1. Prepare the Mower:
- Safety First: Disconnect the spark plug wire to prevent accidental starting.
- Locate the Starter Housing: The starter housing is typically located on the top or side of the engine, near the pull handle.
2. Remove the Old Pull String:
- Remove the Cover: Use the Phillips screwdriver to remove any screws holding the starter housing cover in place.
- Access the String: Once the cover is removed, you should be able to see the old string connected to the starter mechanism.
- Release the String: Carefully unhook the string from the starter mechanism.
3. Install the New Pull String:
- Attach the String: Feed the new string through the starter mechanism’s guide holes, following the same path as the old string.
- Secure the String: Secure the string to the starter mechanism. This is typically done by wrapping the string around a small hook or peg, then securing it with a knot.
- Rewind the String: Hold the string taut, and slowly pull the handle to rewind the starter mechanism. This will ensure the string is properly wound and ready for use.
4. Reassemble and Test:
- Replace the Cover: Reinstall the starter housing cover and tighten the screws.
- Reconnect the Spark Plug Wire: Reconnect the spark plug wire.
- Test the Pull String: Carefully pull the string a few times to ensure it’s working correctly and the starter mechanism is functioning properly.
Troubleshooting Common Issues
The Pull String Won’t Rewind:
- Loose or Broken Spring: If the spring is loose or broken, the starter mechanism won’t wind the string properly. You may need to replace the spring.
- Damaged Starter Mechanism: If the starter mechanism itself is damaged, it may not rewind the string. This will require professional repair.
The Pull String Breaks Immediately:
- Incorrect String Type: Ensure you’ve purchased the correct type of string for your lawn mower.
- Improper Installation: Double-check that the string is properly installed and secured in the starter mechanism.
- String Tension: The string tension can affect its lifespan. Adjust the tension as needed.
Additional Tips for Success
- Choose Quality Pull String: A high-quality string is essential for longevity. Opt for a string made from durable materials like nylon or polyester.
- Avoid Over-Tightening: Tighten the starter housing cover screws firmly but avoid over-tightening, which can damage the housing.
- Regular Maintenance: Regularly inspect the pull string for signs of wear or damage. Replace it proactively to prevent unexpected issues.
When to Seek Professional Help:
If you encounter persistent problems with your lawn mower’s pull string or starter mechanism, it’s best to consult a qualified lawn mower repair technician. They can diagnose the issue and provide appropriate solutions.

FAQ
1. What tools do I need to change a pull string on a lawnmower?
You’ll need a few basic tools to change a pull string on your lawnmower. These include a Phillips-head screwdriver, a pair of pliers, a tape measure, and a new pull string. If your pull string has become frayed or broken, it’s essential to replace it for safe and efficient lawn mowing.

2. How do I identify the pull string on my lawnmower?
The pull string on a lawnmower is the rope you pull to start the engine. It’s usually connected to the recoil starter, a device that converts the pull force into rotating energy to crank the engine. It’s often located at the top or side of the lawnmower, and it may be enclosed in a housing or cover. The pull string typically has a loop or handle at the end for easy gripping.
If you are unsure where the pull string is located, consult your lawnmower’s manual or find an online video showing how to identify it for your specific model. Once you’ve located the pull string, you can begin the process of changing it.
3. Can I use any type of string for a pull string?
Using the wrong type of string can lead to problems, so it’s crucial to use a string specifically designed for lawnmower pull starts. Regular string or rope may be too thick or weak, which can cause it to break or fray during use.
It’s also important to consider the length of the new string. Measure the old string and ensure the new one is the same length. Using a string that’s too long or short can affect the recoil starter’s performance.
4. How do I know when to change a pull string?
There are a few signs that your lawnmower’s pull string needs to be replaced. If the string is frayed, worn, or broken, it’s time to replace it. This can lead to difficulty starting the lawnmower or even damage to the recoil starter.
You should also consider replacing the pull string if it feels weak or difficult to pull. A loose or worn-out pull string can also lead to problems starting the lawnmower. Taking preventative measures to replace the pull string when it shows signs of wear can help prevent more serious problems with your lawnmower.
5. Can I change a pull string without disassembling the lawnmower?
You can generally change a pull string without completely disassembling the lawnmower. However, you will need to remove the pull starter housing and access the recoil starter mechanism. The process involves releasing the old string from the recoil starter and attaching the new one.
You may need to loosen or remove some screws and clips to access the pull string. Be sure to consult your lawnmower’s manual or find a video tutorial online for detailed instructions specific to your model. With proper guidance and the right tools, changing the pull string can be a simple and straightforward task.
6. What if I can’t find a new pull string for my lawnmower?
If you can’t find a specific pull string for your lawnmower, consider using a compatible replacement string. Look for a string that is the same diameter and material as the original pull string. Be sure to measure the length of the old string and use a new string of the same length.
You may also want to contact the manufacturer of your lawnmower for assistance in finding a compatible replacement string. With some research, you can find the right replacement pull string and get your lawnmower back in working order.
7. Can I prevent my pull string from wearing out?
While you can’t entirely prevent pull string wear, you can extend its life. Start by using proper technique when pulling the string, avoid jerking or sudden movements, and ensure a smooth, consistent pull. Regularly inspect the pull string for signs of wear and replace it at the first sign of damage.
Keep the pull string clean and free of debris. Dirt and grime can accumulate on the string, which can cause it to fray or wear out faster. Proper maintenance and careful handling can help your pull string last longer and keep your lawnmower running smoothly.
