Replacing the Blade

If your string trimmer head isn’t cutting the grass as well as it used to, it might be time to replace the blade. You can do this with just a few simple tools and supplies, and it’ll save you time and hassle in the long run.


1 Start by unplugging the string trimmer. Make sure you have the right tools before you start—you’ll need a Phillips head screwdriver and a wrench.
