How Often Should Mower Blades Be Sharpened?

All lawn care professionals know that a good mower blade is one of the most important things for a healthy, green lawn. The question is, when should you sharpen your lawnmower blades?

Let’s dig into the answer.

How Often Should You Sharpen Your Blades?

The short answer is:

A lawnmower blade should be sharpened after every 20 to 25 hours of usage time on average.

In reality, the best time to sharpen blades is when they start getting dull and it becomes more difficult to cut grass. Blades that have been sharpened too early will wear out faster than necessary which can cause problems with traction or other safety issues.

Sharpening blades in a timely manner will help to ensure your lawn is getting the best and most consistent cut possible.

There are many different types of mower blade sharpener tools on the market today, but if you’re not sure how to use one or aren’t comfortable doing so yourself, it may be better just to bring your lawn mower blades to a professional for sharpening.

Don’t Sharpen Your Mower Blades Too Often

Blades that are sharpened too often will actually do more harm than good, and they won’t last as long either. It can make them dull faster which makes for poor-quality cuts that could damage your lawn.

Sharpening blades too often can also cause excess wear on the engine since mower engines need to work harder to pull duller blades through the grass.
