New lawn mower blades come pre-sharpened from the factory, so immediate sharpening is usually unnecessary. However, even new blades can become dull over time due to exposure to debris.
Maintaining sharp lawn mower blades is essential for keeping your lawn healthy and attractive. Dull blades tear and shred the grass, which results in uneven grass height and frayed tips on the grass blades.
The first sign is uneven grass height. When your blades are dull, they may leave behind uneven patches of grass, which can make your lawn look patchy and unkempt.
- Avoid mowing over rocks or other debris - Adjust your mower’s height settings - Clean your mower after each use
