Repost via Carolawna. "Did you know that we replace our mower blades regularly to ensure the sharpest cut possible? A dull blade rips and pulls the grass blades, leaving ragged tears that both weaken the plant and promote fungal growth and other grass diseases. A sharp blade, on the other hand, cuts cleanly, allowing the plant to heal and recover quickly. This is just one of the ways that we stay 'a cut above our competition!'"
