Understanding the Pull Cord System
The pull cord is the lifeline to your Craftsman lawn mower’s engine. It’s a simple but crucial component that transforms your physical effort into the power needed to start the engine. Here’s how it works:
- Pulling the cord: When you pull the cord, you engage a spring-loaded mechanism that rotates a small flywheel.

FAQ
Why is my Craftsman lawn mower pull cord so stiff?
The most likely culprit for a stiff Craftsman lawn mower pull cord is a buildup of dirt and debris in the recoil assembly. Over time, grass clippings, dust, and other particles can accumulate around the spring and other moving parts, creating friction and making it difficult to pull. Another possibility is that the spring itself has become worn or weak, leading to increased resistance.
Inspecting the recoil assembly is the best way to determine the cause. If there is a visible accumulation of dirt, you can try cleaning it with compressed air or a small brush. If the spring appears damaged, it’s best to replace it with a new one.
Can I fix a broken Craftsman lawn mower pull cord myself?
Yes, you can usually fix a broken Craftsman lawn mower pull cord yourself. Most models have a simple design that allows you to easily replace the cord. The process typically involves removing the recoil housing, detaching the old cord, and attaching a new one.
However, if the break is within the recoil assembly, you might need to replace the entire unit. In this case, it’s essential to follow the specific instructions for your model. You can find helpful videos and diagrams online to assist you.
Why is my Craftsman lawn mower pull cord slipping?
A slipping Craftsman lawn mower pull cord indicates that the rope has become worn or that the mechanism that grips the cord is failing. The rope can become frayed or thin over time, causing it to lose its grip and slip when pulled. The grip mechanism, often a small spring-loaded pawl, can also become worn or damaged, leading to slippage.
To fix this problem, start by inspecting the cord for any signs of damage. If it’s frayed or worn, replace it with a new one. If the pawl appears worn, you might need to replace the entire recoil assembly.
How can I prevent my Craftsman lawn mower pull cord from breaking?
Taking proper care of your Craftsman lawn mower can significantly extend the life of your pull cord. Regularly cleaning the recoil assembly to prevent dirt and debris buildup can help reduce friction and strain on the cord.
Additionally, avoid pulling the cord too quickly or forcefully, as this can put extra stress on the mechanism. Always use a firm, consistent pull to start the engine. Remember to keep the cord lubricated with a light oil to reduce friction and extend its lifespan.
What should I do if my Craftsman lawn mower pull cord won’t retract?
A Craftsman lawn mower pull cord that won’t retract might be due to a malfunctioning recoil spring or a blockage in the mechanism. The recoil spring is responsible for retracting the cord after pulling. If it’s broken or worn, the cord won’t retract.
A blockage in the recoil assembly can also prevent retraction. Inspect the mechanism for any signs of debris or obstruction. If the spring appears damaged, you’ll need to replace it. Removing any obstructions might require disassembly of the recoil assembly.
How do I know if I need to replace the entire Craftsman lawn mower pull cord assembly?
If your Craftsman lawn mower pull cord is showing multiple signs of wear and tear, such as excessive stiffness, slippage, or inability to retract, it might be a good idea to replace the entire assembly.
Attempting to fix individual components can lead to further damage or create a temporary fix that won’t last. Replacing the entire assembly ensures a reliable and smooth operation of your mower.
