John Deere lawn mower blades are manufactured with a combination of carbon and boron to provide hardness for a long life and sharp edge without breakage.

John Deere mower blades are designed to exact specifications to achieve the best performance and cut quality. We use high quality steel that stays sharper longer. A flat mounting surface reduces blade stress for long life and excellent cut quality. The properly sized center hole provides for less vibration and increased machine life. Use John Deere mower blades for the best life and performance.
