Sunbelt B1SC3800 16-1/2 in. XHT Mower Blade for 32-in. & 48-in. Decks is designed for superior performance and durability. This newer style blade features a longer air lift, making it i for decks with a 32" or 48" cut, especially those by Scag. Measuring 16-1/2" long by 2-1/2" wide with a 5/8" diameter center hole, it a medium lift with a notched design. The blade is crafted from Sunbelt's patented XHT (Xtreme Hardness & Toughness) Marbain® heat-treated steel, which has been independently tested to provide increased hardness and exceptional resistance to bending and impact damage. This results in a cutting edge that stays sharper longer, with XHT blades being approximately 25% to 40% harder than standard lawnmower blades. The blade maintains tight tolerances, making it an excellent equivalent to Scag 482877, Toro 107-3192-03, Oregon 91-621, Rotary 3403, and Stens 340-874. Each package includes one blade.
