UPGRADED 10B38 MANGANESE STEELForged from premium 10B38 high manganese steel with a heat-treated hardness of HRC 38-44. This professional-grade material provides superior impact resistance and durability, significantly reducing the risk of bending or cracking during heavy-duty mowing.
PRECISION DIMENSIONS & DIAMOND HOLEEach blade measures 21" in length, 2.300" in width, and 0.157" in thickness. Featuring the specialized Diamond Center Hole pattern, these blades are engineered to fit S-Pattern spindles precisely, eliminating the vibration and uneven cuts caused by loose fitting.
SUPERIOR MULCHING PERFORMANCEThe high-lift sharpened edges and optimized airflow design ensure clean cuts and efficient grass recycling. The precision-ground cutting surface reduces grass tearing, promoting a healthier, greener lawn while minimizing resistance for your mower engine.
COMPLETE INSTALLATION KITThe package includes 2 mulching blades, 2 nuts, and 2 washers for a hassle-free replacement. Each blade undergoes rigorous balance testing to 0.001" precision. A corrosion-resistant coating is applied to protect the steel; the paint will naturally wear off the cutting edge during initial use.
