Only then should you begin undoing the blade’s retaining bolt. Once the bolt is loose, you can remove the blade and proceed with sharpening or replacement.

What is the best way to loosen a lawn mower blade?

Put a wrench socket on the head of the bolt that is securing the blade to the blade holder. To loosen the blade bolt, turn the wrench handle counterclockwise.
