Dull mower blades tear off grass rather than cutting it clean, leaving ragged tips that invite disease to set in. Holding the blade in a vise, sharpen it with long, smooth strokes using a Dremel blade sharpener or a 10-inch bastard mill file, following the manufacturer's instructions for the proper angle. During the growing season, sharpen the blade after you've used your mower for about 8 to 12 hours.
