A dull lawnmower blade leads to a really poor cut on your grass. If the blade is dull enough instead of cutting cleanly the blade will just tare and crush the grass plants.

You only need 2 tools to sharpen your lawnmower blade. First, you will need a properly sized socket wrench to remove the blade from the mower.
Second, you will need a good quality metal file to do the actual sharpening.
Removing the blade from your mower
It is easiest to sharpen your lawn mower blade if it has been removed from the mower. For most mowers all this will require is removing one bolt using a wrench or socket set. Depending on how long it has been since the blade was last removed you may need to use some good force to get the bolt loose. Hold the blade from turning with one hand (keeping your hand off the sharp part of the blade) and loosen the bolt with the other hand.
Once the center bolt has been removed the blade should slide downwards off the blade shaft.

Once the blade has been removed sharpen with the metal file. Use forward strokes only (don’t file back and forth) towards the factory edge. For most lawn mowers only the end 4 to 6 inches of the blade will need to be sharpened. Using the file remove any burs or dented spots on the blade and then file a nice sharp edge all along the cutting surface.
Once the blade is sharpened put it back on the mower and tighten the bolt to the manufactures specifications in your owners manual.
