How Often To Sharpen Mower Blades? (Overview)
A general rule is to sharpen your lawn mower blades at least once a year or after every 10 hours of use to keep them sharp. However, this time frame can vary depending on factors like grass type, blade condition, and mowing frequency.
4 Signs That Tell You When to Sharpen Lawn Mower Blades
Personally, I make sure to sharpen my lawn mower blades when getting my mower ready for spring or when winterizing my mower. But beyond that, instead of relying solely on a schedule, it’s important to pay attention to your mower’s performance and watch for signs that your blades need sharpening. Here are some common signs to look out for:
Uneven cuts
If your mower is leaving behind uneven patches of grass or it seems like the blades are spinning but not cutting, then it’s a sign that your blades are dull and not working properly. This can be especially noticeable if you have a pattern or stripes in your lawn.
Ragged Edges
Dull blades can tear the grass instead of making clean cuts, which can lead to ragged edges and a brown appearance. This is because torn grass blades are more susceptible to disease and pests, which can further damage your lawn.
Grass Clippings
If you see more clippings than usual or they’re not discharging evenly, it’s a sign that your blades are struggling to cut the grass cleanly. This can also lead to clumps of grass clippings on your lawn, which can block sunlight and nutrients from reaching the grass.
Vibrations
A vibrating mower can indicate that the blades are unbalanced or damaged, which can lead to uneven cuts and damage to the mower. If you notice vibrations while mowing, it’s important to check your blades for damage or balance issues.
Factors that Can Affect How Often to Sharpen Lawn Mower Blades

So, understanding your lawn, the mowing conditions, and when you last sharpened your lawn mower blade will help to determine when your blade needs sharpening. Here’s a list of some common factors that can affect how often a lawn mower blade needs to be sharpened.
- Type of grass being mowed
- Frequency of mowing
- Condition of the blades
- Height of the grass being mowed
- Terrain or slope being mowed
- Blade quality
- Amount of debris in the yard
- Whether the blades hit rocks or other objects during use
