What can happen if the blades on a lawn mower are not sharpened regularly?

Regularly sharpening the blades of a lawn mower is crucial for maintaining its performance. When mower blades are dull, rather than cutting the grass cleanly, they tend to tear or rip it. This tearing can cause multiple issues: it creates jagged edges on the grass blades, which makes them more susceptible to diseases and pests. Additionally, torn grass can lead to an uneven appearance in the lawn and may require more frequent mowing due to reduced growth vigor. A clean cut from sharp blades, on the other hand, promotes healthier turf since the grass can recover more effectively. Therefore, ensuring that blades are kept sharp is essential for both the health of the grass and the efficiency of the mower.
