2. Un-Stain The Mower Blade

3. Rake The File Between The Blades

Push the metal mill’s sharp end onto the first blade’s dull edge slowly and cautiously. The blade edges should now be scratched with the file. To slide the file along the length of the blades, always be alert. Don’t attempt to create new cutting angles, either.

The dull cutting angle should only be decreased by one or two millimeters.

Repeat it multiple times. It is completely based on the state of the blade. However, we advise doing so seven times or more.

4. Repeat Previous Steps For all Blades

Now that you are done sharpening the blade’s edge, you can carefully remove the broomstick. Gently rotate the mower cylinder to access the next blade completely.

Then, secure the blades once more and go through the process again to sharpen any further dull blades.

5. Use Grease and Lubricate to Protect Blades After Sharpening
