Sunbelt B1HS1008 18-1/2-in. XHT Mower Blade for 54-in. Decks is designed for mower decks with a 54-inch cut, specifically fitting models like the Hustler Fastrak (797696). This blade measures 18-1/2 inches in length and 2-1/2 inches in width, featuring a 5/8-inch diameter center hole and a medium lift design. Engineered with Sunbelt’s XHT (Xtreme Hardness & Toughness) technology, it uses a patented Marbain® heat-treated steel that delivers superior hardness and exceptional resistance to bending and impact damage. This innovative material keeps the cutting edge sharper for a longer time, making the blade approximately 25% to 40% harder than standard lawnmower blades. The Sunbelt B1HS1008 ensures precise cutting performance with tight tolerances, matching or exceeding equipment standards. It is equivalent to blades such as Hustler Fastrak (797696), Oregon 92-042, Rotary 11856, and Stens 350-695. Model Number: B1HS1008
