Sharpening mower blades is important for several key reasons:
1. Cleaner Cuts
- Sharp blades cut grass cleanly, like scissors, instead of tearing it.
- Torn grass blades are more prone to disease, browning, and stress.
2. Healthier Lawn
- Clean cuts heal faster, reducing the chance of pests and fungal infections.
- It promotes thicker, more even grass growth.
3. Improved Efficiency
- Sharp blades reduce the strain on your mower’s engine because it doesn't have to work as hard.
- You’ll use less fuel or electricity and get the job done faster.
4. Better Appearance
- A dull blade makes grass look frayed and uneven, giving your lawn a ragged or patchy look.
- Sharp blades give that clean, manicured finish.
5. Prolongs Mower Life
- Less strain on the motor and components means less wear and tear over time.
- Sharp blades are easier on belts and spindles too.
How Often to Sharpen:
- Every 20–25 hours of mowing time (or at least once or twice per mowing season, depending on use and terrain).
If your lawn looks uneven or starts browning after mowing, it’s a clear sign your blades might need sharpening.
