John Deere Self-Sharpening Mower Blade For 60-Inch Decks
The John Deere self-sharpening blade is a patented technology that applies a layer of extremely hard material on the bottom side cutting edge of the mower blade. Mower blades have a significant impact on the cut quality and require regular maintenance to keep the blades sharp. The layer of hard material applied to the bottom of the blade wears at a slower rate than the standard steel mower blade. By creating a different wear pattern, the hard material is exposed continuously creating a sharp edge. As the mower blade is used, the base steel of the mower blade continues to wear faster than the added material which provides a continuous edge that essentially self sharpens itself.
