Dull mower blades are the most overlooked cause of an unhealthy lawn. Instead of cutting grass cleanly, dull blades tear and shred grass blades, leaving ragged edges that turn brown, invite disease, and stress roots.
Sharp mower blades can make all the difference between a pristine lawn and a damaged one. Sharpening your lawn mower blades takes about 30 minutes, requires no professional help, and saves you money on premature blade replacements.
