Replacing the pull string on your Craftsman lawn mower involves a few key steps. You will carefully detach the recoil starter, feed in a new rope, and then reassemble everything. It is a common repair that many homeowners tackle themselves, saving both time and money (Consumer Reports).
We found that a methodical approach makes this task much easier to manage. Just take your time with each step, especially when handling the recoil spring, and you will be back to mowing in no time.
Is Your Pull String Broken?
Has your Craftsman lawn mower’s pull string snapped, frayed, or simply lost its tension? It is a common problem, often happening right when you need to mow your yard. Many homeowners face this inconvenience, wondering if they need a costly repair.
Before you toss out your trusty mower, consider that a broken pull string is usually a straightforward fix. It is like replacing a shoelace; a minor part, but essential for function. You just need to know the right steps.
Why Does a Pull String Break?
Pull strings endure a lot of stress with every start. Over time, constant pulling and friction against the housing can cause wear and tear. We found that environmental factors like humidity or extreme temperatures can also weaken the rope material.
Sometimes, improper starting techniques, like pulling too hard or letting the rope snap back quickly, contribute to early breakage. A poorly maintained recoil system can also cause the rope to fray faster.
Gathering Your Tools
Before you begin, gather everything you will need. Having your tools ready prevents frustrating interruptions during the repair. It is like preparing ingredients before cooking; everything runs smoother.
- New pull string (appropriate length and diameter for your Craftsman model)
- Replacement starter handle (optional, if yours is also damaged)
- Socket wrench set or nut drivers
- Screwdrivers (Phillips and flathead)
- Needle-nose pliers
- Utility knife or sharp scissors
- Work gloves
We recommend checking your mower’s manual for specific rope dimensions if you are unsure. A quick online search with your mower model number often provides this information.
Safety First: Preparing Your Mower
Safety is not just a suggestion; it is a necessity when working with power equipment. Neglecting proper safety steps can lead to serious injury. Think of it as putting on a seatbelt before driving.
Always ensure your workspace is well-lit and clear of clutter. This helps prevent trips or fumbling with tools. Wearing work gloves protects your hands from sharp edges or grime.
Disconnecting the Spark Plug
This is arguably the most important safety step. Before touching anything else, locate the spark plug wire and pull it off the spark plug. Many experts say this prevents the engine from accidentally starting while you work (Occupational Safety and Health Administration).
Securing the wire away from the spark plug terminal is a good practice. You can even tape it to the engine housing or place a rag over it. This gives you peace of mind as you proceed.

Remember, patience is key. If you feel stuck, take a break and then revisit the step. You have got this, and many people have successfully done it before you!
Removing the Recoil Starter Assembly
Your recoil starter is typically mounted on the engine with several bolts or screws. Use your socket wrench or screwdriver to carefully remove these fasteners. Keep them organized; a small magnetic tray works wonders.
Once the fasteners are out, gently pull the entire recoil starter assembly away from the engine. Sometimes, it might be a bit snug, so a slight wiggle helps. Do not force it; look for any hidden clips or attachments.
Cutting the Old Rope
If there is still a piece of the old rope visible, use your utility knife or scissors to cut it. Then, remove any remaining rope from the handle and the recoil pulley. You want a clean slate for your new rope.
Make sure no frayed bits are caught in the recoil mechanism. These small fibers could cause issues later. A pair of needle-nose pliers can help fish out stubborn pieces.
Winding the Recoil Spring
This is often the trickiest part, but it is totally manageable with care. The recoil spring is under tension, so always handle it carefully. You need to wind the spring to create tension for the new rope.
Many experts suggest winding the pulley clockwise until you feel resistance, usually about 3-5 full turns. Hold it in place while you prepare to thread the new rope. If the spring comes loose, it can be frustrating to re-seat, but not impossible.
Aligning the Rope Pulley
While holding the wound pulley, align the hole in the pulley with the hole in the recoil starter housing. This is where your new rope will pass through. It is like lining up a key with a keyhole.
Some assemblies have a notch or guide for the rope. Make sure everything is aligned perfectly before proceeding. Proper alignment prevents the rope from rubbing or snagging during operation.
Threading the New Pull String
Now, take your new pull string and carefully thread one end through the hole in the recoil starter housing. Then, push it through the corresponding hole in the pulley. This might require a little patience and the help of needle-nose pliers to guide it.
Once threaded, tie a secure knot, like an overhand or figure-eight knot, at the end of the rope inside the pulley. Make sure the knot is large enough not to pull back through the hole. Trim any excess rope.
Tying the Starter Handle
With the new rope threaded and knotted inside, slowly release the tension on the pulley until the rope is fully retracted into the housing. Now, thread the other end of the rope through your starter handle.
Pull the rope taut and tie another strong knot on the handle side. Ensure the knot is flush against the handle and will not slip. You want about 6-12 inches of rope extending from the housing when the handle is against it.
Reattaching the Recoil Starter
Place the recoil starter assembly back onto the engine, aligning it with the mounting holes. Reinstall all the bolts or screws you removed earlier. Make sure they are snug, but avoid overtightening, which can strip threads.
Give the starter handle a gentle pull to ensure everything feels secure and moves freely. The rope should retract smoothly without sticking. This is your first check for proper assembly.
Testing Your New Pull String
Once the assembly is firmly back in place, reattach the spark plug wire to the spark plug. Now, give the pull string a few practice pulls. It should feel smooth, with good tension, and the rope should retract fully.
Then, try starting your Craftsman lawn mower. Does it start up on the first or second pull? If so, you have successfully completed the repair! If not, recheck your steps, especially the recoil spring tension.
| Issue | Possible Cause | Solution |
|---|---|---|
| Rope does not retract fully | Insufficient spring tension | Rewind the recoil spring with more turns (1-2 extra). |
| Rope feels loose after replacement | Not enough initial tension on spring | Repeat spring winding, ensuring proper pre-tension. |
| Rope gets stuck or rubs | Incorrect threading or damaged pulley | Check rope path; inspect pulley for cracks or rough spots. |
| Engine will not turn over with new rope | Spark plug wire not connected / other engine issue | Verify spark plug connection. Check fuel, oil, air filter. |
When to Call a Professional
While replacing a pull string is generally a DIY-friendly task, there are times when seeking professional help is the smarter choice. No shame in knowing your limits, right?
If you encounter significant resistance when winding the spring, or if the spring itself appears broken or severely corroded, it might be best to consult a small engine mechanic. They have specialized tools and expertise for more complex repairs (Briggs & Stratton).
Common Pitfalls to Avoid
Want to make sure your repair goes smoothly? Avoid these common issues that some people run into:
- Forgetting the spark plug: Always disconnect it first!
- Overtightening screws: Stripped threads are a pain to fix.
- Incorrect rope length: Too short, and it will not engage; too long, and it wraps poorly.
- Improper spring tension: Too little, it will not retract; too much, and it breaks easily.
- Losing small parts: Keep screws and springs organized.
By being mindful of these points, you set yourself up for a successful and frustration-free repair. A little foresight goes a long way!
Conclusion
Replacing the pull string on your Craftsman lawn mower is a repair you can absolutely manage with the right tools and a careful approach. By prioritizing safety, systematically removing the old rope, and patiently installing the new one, you restore your mower’s starting power.
This repair not only saves you money but also gives you a real sense of accomplishment. Your lawn mower is ready to tackle that grass once again, all thanks to your efforts. Happy mowing!
What is the correct length for a Craftsman lawn mower pull string?
The correct length for a Craftsman lawn mower pull string typically ranges from 7 to 8 feet (around 84 to 96 inches) for most standard models. However, it is always best to check your specific mower’s owner’s manual or measure the old string to ensure accuracy. A string that is too short will not allow full engagement, and one too long can cause tangling.
Can I use any type of rope for my lawn mower pull string?
No, you should not use just any type of rope. Lawn mower pull strings are made from specialized, heavy-duty material, often nylon or polyester, designed to withstand high friction, oil, fuel, and the constant stress of pulling. Using a regular rope could lead to quick breakage, fraying, and potential safety hazards. Always opt for a high-quality replacement pull starter rope.
How do I know if my recoil spring is broken or just needs re-tensioning?
If your pull string does not retract at all, or retracts very slowly after being pulled, the recoil spring might be the culprit. If the spring feels completely loose or you can see visible breaks or deformation within the spring assembly once the starter is open, it is likely broken and needs replacement. If it has some tension but not enough to fully retract, it often just needs to be re-tensioned properly.
What should I do if the engine still will not start after replacing the pull string?
If the engine still will not start after replacing the pull string, the issue is likely elsewhere. First, double-check that the spark plug wire is securely connected. Then, consider common starting problems: ensure there is fresh fuel, the oil level is correct, the air filter is not clogged, and the carburetor is not gummed up. If these basic checks do not resolve it, a deeper diagnostic might be needed, possibly involving the spark plug itself or the fuel system.
Is it possible to replace the recoil spring without buying a whole new assembly?
Yes, it is often possible to replace just the recoil spring without buying an entire new starter assembly. Many replacement springs are available for purchase separately. However, replacing the spring itself requires careful handling, as they are under significant tension and can be difficult to re-seat properly. If you are uncomfortable working with spring tension, replacing the whole assembly might be a simpler, albeit costlier, option.
