Before you begin sharpening your mower blades, make sure you have the following tools on hand and within easy reach:

  • Safety kit
  • Googles/ gloves
  • A wire
  • A Wood block
  • Steel wire brush
  • A flat file
  • Putty knife
  • Penetrating oil

Steps To Clean The Mower Blades:

1)Unplug The Power Source:

To protect yourself from any accidental starting or turning while working, make sure you disconnect the lawnmower from all possible power sources. Moreover, double-check that the spark plug cable is unplugged from the spark plug or unplug the power cord.

Place your lawnmower on its side, with the carburetor facing up on a gas mower. Additionally, place a wood block underneath the engine or motor to improve stability while working on the mower. When sharpening your lawnmower without removing the blades, plugging off all the switches and power supplies is the primary step to consider.

2)Remove The Retaining Nuts Or Bolts:

To loosen the nut or bolt, use a big ratcheting wrench and socket. Apply some penetrating oil, such as Liquid Wrench, for the rusted fasteners. Let the oil sit on the surface for at least 10 minutes. Use a metal pipe over the wrench handle to enhance leverage when loosening a tough bolt.

Additionally, pull the mower blade off after removing the retaining nut or bolt, noting which side of the blade faces downward. Undoubtedly, it’s not as easy as one thinks to reinstall the blades in the same position.

3)Clean The Underside Of The Blades:

Take a minute to scrape the underside of the mowing deck clean with a putty knife after removing the blade. Grass, mud, leaves, and other debris should all be removed. Moreover, clean both sides of the lawnmower blade by scrubbing with a metal

-bristle brush after spraying with penetrating oil. A cutting edge on each end of a lawnmower blade is usually positioned on different sides of the blade. Each cutting edge is only a few inches long and does not extend the blade’s length. Clamp the blade at an angle in a vice, with one of the cutting edges facing up.

4)Sharp The Blades:

Now, it’s time to sharpen the blades after appropriate cleaning with the metal wire brush or penetrating oil. For sharpening the blades, take a flat file and place it over the blade’s cutting edge. Make sure to begin sharpening from the blade’s middle and maintain a suitable angle.

After sharpening one side of the blade appropriately, turn to the other side to complete the sharpening procedure. Repeat the process if needed.
