Sharpening your push mower blades is an important part of lawn maintenance. Dull blades will not cut the grass cleanly, which can lead to a brown or uneven lawn. Sharpening your blades regularly will help your mower cut more efficiently, resulting in a healthier, greener lawn.
There are a few different ways to sharpen your push mower blades. You can use a file, a grinding wheel, or a sharpening stone. If you are not comfortable sharpening your blades yourself, you can take them to a lawn mower repair shop and have them sharpened professionally.
