In essence, replacing a lawn mower pull string is a straightforward process. You’ll need to access the engine’s recoil assembly, remove the old string, and install a new one. While the specific steps might vary slightly depending on your mower’s model, the core principles remain consistent.
Identifying the Correct Pull String
Before embarking on the replacement process, it’s essential to ensure you have the right pull string for your mower. The wrong size or type of string can lead to improper tension or even damage to the recoil assembly.
Understanding Pull String Specifications

- Diameter: Pull strings typically have a diameter of 1/8 inch or 3/16 inch.
Finding the Right Replacement
- Refer to your mower’s manual: The manual should specify the exact pull string length and diameter required for your model.
- Check the old string: Measure the length and diameter of the existing string for reference.
- Contact your mower’s manufacturer: If you can’t locate the information in the manual or on the old string, contacting the manufacturer directly is always a reliable option.
