How to Choose the Right File for Sharpening Your Lawn Mower Blade

1. Consider the type of blade on your lawn mower

The type of blade on your lawn mower will determine the type of file needed to sharpen it. Rotary mower blades have a curved cutting edge and require a curved file, while reel mower blades are straight and require a straight file. Using the wrong file can result in damaging the blade or even the file.

2. Take note of the level of dullness

The level of dullness of the blade dictates the type of file grit to use. For blades heavily damaged, a coarse file is recommended. For minor touch-ups, a finer file would suffice. Ensuring the proper grit level for your file ensures an efficient and effective sharpening process.

3. Choose the right file size

To avoid uneven sharpening or damaging the blade, choosing the right file size is essential. It is recommended that the file’s length should exceed the width of the blade, which can provide a balance in sharpening the blades.

4. Check the file’s teeth count

The number of teeth in different files may vary depending on the manufacturer. Using different teeth counts may deliver varying results. For a lawn mower blade, a file with around 8-10 teeth per inch is the ideal choice.

5. Select the appropriate file handle

Using a file with the right handle is essential for a comfortable grip and efficient use. A rubberized handle, when available, is recommended to provide a sturdy grip and safety from slipping. A comfortable grip ensures a smooth and safer sharpening process.

Picking the right file for sharpening your lawn mower blade is essential for efficient and safe results and the tips above should help with that.
