When to replace your lawn mower blade

Even if you sharpen the blade, there will come a time when it needs to be replaced. A lawn mower blade is made of metal, and over time it will become worn out from all the cutting.

How to tell if it’s time to replace the blade?

  • You’ll know it’s time to replace the blade when you see signs of wear and tear, such as cracks, chips, or nicks in the metal.
  • Check the thickness of the blade. If it’s become thinner from all the sharpening, it’s time for a new one.
  • The evenness of your lawn will also be a good indication of whether the blade needs to be replaced. If you notice that the lawn isn’t being cut as evenly as it used to, it’s probably time for a new blade.
  • Check your lawn’s grass blades after cutting to see if they have a ragged appearance. If the blades look frayed or shredded, the blade is dull and needs to be replaced.

Do it after you’ve put your child to bed, or whenever you’re feeling free and calm. Choose a sharpening tool that’s right for your blades. It should be lightweight and portable, or else you’re wasting your time.
