You’re ready to tackle your lawn, but your trusty mower isn’t cooperating. The pull string, the lifeline of your gas-powered mower, is acting up. It’s frayed, broken, or simply won’t recoil properly. This frustrating situation can leave you feeling helpless and stuck with an overgrown lawn. But fear not! Replacing your lawn mower pull string is a surprisingly simple task, even if you’ve never tackled a repair before. This guide will walk you through the process, step-by-step, so you can get your mower back in working order and your yard looking pristine in no time.
A Short Overview
Replacing a lawn mower pull string is a straightforward process that usually involves removing the old string, threading a new one through the mechanism, and reassembling the parts. You’ll need a new pull string and a few basic tools like pliers, a screwdriver, and a small wrench. With a little patience and this guide, you’ll be ready to tackle even the most stubborn lawn with a freshly-repaired mower.
Getting Started: Gathering Tools and Materials
Before you jump into the repair, you’ll need to make sure you have the right tools and supplies on hand. This will ensure a smooth and efficient repair process. Here’s a list of what you’ll need:
- New Pull String: The most important component, of course, is a replacement pull string. You can find these at your local hardware store or online. Make sure you get a string that’s compatible with your specific mower model.
- Pliers: A pair of pliers will come in handy for gripping and pulling components.
- Screwdriver: A standard screwdriver will be needed to loosen and tighten screws during the disassembly and reassembly process.
- Small Wrench: A small wrench might be necessary for loosening and tightening any nuts or bolts that secure the pull start mechanism.
- Work Area: Clear a clean and well-lit workspace where you can spread out your tools and parts.
Disassembling the Pull Start Mechanism
Now that you’ve got all your tools, it’s time to take your mower apart. This process might seem intimidating at first, but it’s actually quite simple.
1. Locate the Pull Start Housing
First, you’ll need to locate the pull start housing on your mower. It’s typically found on the top or side of the engine and looks like a small black or grey housing with the pull cord attached.
2. Remove the Housing Cover
Once you’ve located the housing, you’ll need to remove the cover. The cover usually has a few screws holding it in place. Carefully loosen and remove these screws using your screwdriver.
3. Release the Pull Cord
With the cover off, you’ll see the pull string mechanism. The pull cord is held in place by a spring-loaded hook or a similar mechanism. Gently pull the cord out, releasing it from its hook.
Installing the New Pull String
Now that you’ve removed the old pull string, you can install the new one. Follow these steps carefully:
1. Thread the New String
Take your new pull string and thread it through the pull start mechanism. The exact routing will vary depending on your specific mower model, but generally, you’ll need to thread the string through the following:
- The Starter Pawl: This is the small metal hook that engages with the starter gear.
- The Spring Housing: The spring housing guides the string and helps it recoil back into place.
2. Secure the New String
Once the string is threaded through the entire mechanism, secure it in place. This may involve:
- Hooking it onto the starter pawl.
- Tying a small knot at the end of the string.
- Securely winding the string around a spring or a retainer.
Reassembling the Pull Start Mechanism
With the new pull string installed, it’s time to put everything back together:
1. Replace the Housing Cover
Place the housing cover back on the pull start mechanism. Align the screws and tighten them securely.
2. Test the Pull String
Once the cover is back on, test the pull string to ensure it’s working correctly. Pull the string several times to ensure it recoils smoothly and the starter pawl engages properly.
Troubleshooting and Tips
While replacing your pull string is a fairly straightforward process, there are a few things to keep in mind:
- Incompatible String: If the new pull string doesn’t seem to fit or work correctly, you might have chosen the wrong type of string. Make sure to choose a string that’s compatible with your specific lawn mower model.
- Twisted String: If the string is twisted or tangled, it won’t recoil properly. Make sure the string is untangled before you install it.
- Spring Tension: If the spring tension is too weak or too strong, the pull string might not recoil properly. You can adjust the spring tension by loosening or tightening the screws that secure the spring housing.
Conclusion
Replacing a lawn mower pull string is a simple repair that can be done with a few basic tools and a bit of patience. With this guide, you should now be equipped to handle this common lawn mower problem, getting your mower back in working order and your lawn looking its best.

FAQ
Why is my lawnmower’s pull string so hard to pull?
There are a few reasons why your lawnmower’s pull string might be difficult to pull. The most common reason is that the engine is flooded with fuel. This can happen if you try to start the lawnmower when it’s cold or if you’ve left the choke on for too long. Another possibility is that the spark plug is fouled. This can happen if the lawnmower hasn’t been used in a while or if you’re using the wrong type of fuel. If the pull string is still hard to pull after checking these things, it might be a problem with the engine itself.
It’s important to note that a hard-to-pull lawnmower can also be a sign of a more serious problem. If you’ve checked the common causes and the pull string is still difficult to pull, it’s best to take your lawnmower to a qualified mechanic for diagnosis and repair.
What can I do to fix my lawnmower’s pull string?
There are a few things you can do to try to fix a lawnmower pull string that’s giving you trouble. First, try to start the lawnmower with the choke on. If that doesn’t work, try to start the lawnmower with the choke off. If neither of these methods works, you can try to clean the spark plug. To do this, remove the spark plug and use a wire brush to clean the electrodes. You can also try to adjust the carburetor. To do this, you will need to consult your lawnmower’s manual.
If none of these solutions work, it’s best to take your lawnmower to a qualified mechanic for diagnosis and repair.
How do I prevent my lawnmower’s pull string from breaking?
The best way to prevent your lawnmower’s pull string from breaking is to use it properly. Make sure you pull the string smoothly and steadily. Avoid jerking the string or pulling it too hard. You should also make sure that the string is properly lubricated. You can do this by using a few drops of oil on the string.
Another important factor is to keep the lawnmower clean. This includes removing any grass clippings or debris from the engine and around the pull string. By keeping the lawnmower clean and well-maintained, you can help prevent the pull string from breaking.
What should I do if my lawnmower’s pull string breaks?
If your lawnmower’s pull string breaks, don’t panic. You can usually replace the string yourself. First, you need to identify the type of string you have. Look closely at the end of the string – some strings are braided, some are solid. Depending on the type of string you have, you can purchase a new one at most hardware stores. To replace the string, you will need to remove the old string and then thread the new string through the pull starter assembly.
If you’re not comfortable replacing the string yourself, you can take your lawnmower to a qualified mechanic. They can replace the string for you and make sure that it’s properly installed.
How do I know if my lawnmower’s pull string is too short?
A too-short pull string can make it difficult to start the engine. It might be challenging to get a good pull, resulting in a weak start or not starting at all. If the pull string is too short, it might also be difficult to keep a good grip on the handle. When you pull the string, make sure it is extending out at least two-thirds of the way before the recoil spring engages. If it is not, your pull string may be too short.
If the string is too short, you can try to adjust it. To do this, you will need to remove the cover of the pull starter assembly and then loosen the tension on the string. You can then adjust the string length and then re-tighten the tension.
How often should I replace my lawnmower’s pull string?
The lifespan of a lawnmower pull string depends on various factors, including usage, maintenance, and the quality of the string itself. However, it’s generally recommended to replace the pull string every 2-3 years. You should also replace the pull string if it shows any signs of wear and tear, such as fraying, cracking, or breakage.
Regularly inspecting the string is essential. If you notice any wear or damage, it’s best to replace it immediately to prevent unexpected breakdowns and ensure a smooth and hassle-free lawnmowing experience.
What other problems can cause my lawnmower’s pull string to be difficult to pull?
While a difficult-to-pull lawnmower pull string often indicates an issue with the engine, there could be other factors at play. One possibility is that the recoil spring is worn out or broken. This spring is responsible for retracting the pull string, and if it’s not working properly, it can make the string harder to pull. Another potential cause is a buildup of dirt or debris in the pull starter assembly. This can impede the movement of the string and make it harder to pull.
In addition to these issues, the pull start cable itself might be tangled or knotted, making it stiff and hard to pull. Finally, a worn or damaged pull start handle could also contribute to the difficulty in pulling the string. If the pull string is consistently hard to pull despite addressing common problems, it’s best to seek professional help from a qualified mechanic.
