How and Why should I sharpen my lawn mowers blade?
Every month or two, you should sharpen the lawn mower’s blade. The reason for sharpening lawn mower blades is that dull blades have a tendency to rip grass blades instead of cutting cleanly, leaving grass susceptible to diseases. Here’s how to sharpen a lawn mower blade: • First remove the spark plug wire to ensure the lawn mower doesn’t start up accidentally, resulting in injury. • With a wrench, remove the nut that holds the lawn mower blade up against the deck, then remove the blade. • Use a file to do the sharpening. Follow the angle of the cutting edge that’s already there (the angle will be roughly 45 degrees).
