The cutting edges are painted to prevent rust and protect your hands during installation. The paint will wear off as you mow the grass. 2-IN-1 BLADE: Serves 2 purposes (bagging and side discharging) at the same time. Perfect for cutting tall or wet grass, the high-lift blade design creates powerful airflow and suction, providing the fastest mowing speed and propelling clippings into the collection bag or discharge chute.
