Before sharpening it, clean or wash your mower blades with the help of the brush or washer to remove all possible dirt and debris; it will prevent any hurdle during the sharpening of the blade.
Step 2. Start With the Sharpening of the Blade
You can use the sharping of the mower blade by using the best blade sharpeners available on the market. But it would help if you chose the sharpener considering the mower blade’s design, which one will suit you the best.
Once you balance the blade, take the blade grinder and start sharpening the edge of one side of the blade. You must not stop the process until and unless you get the perfect result.
Once you get the sharp and fine edge of the blade on one side, you can switch to the other.
For proper and uniform sharpening, you need to maintain the appropriate angle. When drawing away from the center, you must use consistent strokes; drawing backward is unnecessary while sharpening.

Honing the blade up and down will look fabulous if you maintain the balance and the right angle.

To install a sharpening stone into it, you need a drilling machine. Then turn on the drill, increase the speed, and expose the dull blades.
Apply a few strokes while using the blades, then determine when it is finished. Apply a few more strokes and finish the job if the blades are not sharp enough.
