Installation: Designed for quick, hassle-free installation – the blades fit directly into place. Just remove the old blade, secure the new one, and your mower is ready for clean, efficient cutting.
Sharpness: Each new blade is pre-sharpened but covered with safety paint that wears off during initial operation. For continued peak performance, the blade can be safely resharpened whenever the cutting edge becomes dull.
