Q: What can I do to help my lawn during the winter? A: Sharpen your mower blades and be aware of the signs for additional sharpening

The frequency with which you should sharpen your lawn mower blades depends on various factors, including the size of your lawn, the type of grass, and the condition of your lawn mower blades. However, a general guideline is to sharpen your mower blades at least two to three times during the mowing season.

In the Midwest, where cool-season grasses like Kentucky bluegrass, fine fescue, and perennial ryegrass are common, the growing season typically spans from late spring through early fall. Here are some considerations for sharpening mower blades in the Midwest:

1. Frequency of mowing: If you mow your lawn frequently, you may need to sharpen the blades more often. For lawns that require weekly mowing, consider sharpening the blades every 8-10 hours of use.
2. Type of grass: Different grass varieties have different blade-wearing characteristics. Fine-textured grasses may dull blades more slowly than coarse-textured grasses. Pay attention to the condition of the grass after mowing—if it looks torn or ragged, it’s a sign that the blades may need sharpening.
3. Mower usage: If you regularly mow over rough terrain, encounter sticks or debris, or accidentally hit rocks, the mower blades can dull more quickly. In such cases, check the blades for damage and sharpen as needed.
4. Blade condition: Inspect your mower blades regularly for signs of dullness, nicks, or damage. Dull blades can tear the grass rather than cutting it cleanly, leading to a less healthy lawn appearance.
5. Seasonal maintenance: It’s a good practice to sharpen your mower blades at the beginning of the mowing season and again midway through the season. This ensures that your blades are in good condition to provide a clean cut, promoting the overall health of your lawn.

Remember, a sharp mower blade contributes to a healthier lawn by cutting grass cleanly, reducing stress on the grass plants, and preventing disease. If you’re not comfortable sharpening the blades yourself, you can take them to a professional mower service or hardware store for sharpening. Additionally, always follow safety guidelines and disconnect the spark plug before removing or working on mower blades.
