Decks, Set of 2 are designed for mower decks with a 42-inch cut, including popular models like Scotts, Sabre, and John Deere L and 100 series. These blades measure 21-1/2 inches long by 2-1/2 inches wide and are .156 inches thick. The center hole diameter is 11/16 inch, with outer holes measuring 13/32 inch in diameter and spaced 3-3/4 inches apart from center to center. Featuring a medium lift design, the set includes two blades. Sunbelt’s XHT (Xtreme Hardness & Toughness) blades utilize a patented Marbain® heat-treated steel, independently tested to ensure increased hardness and superior resistance to bending and impact damage. This technology keeps the cutting edge sharper for longer, making XHT blades approximately 25% to 40% harder than standard lawnmower blades. They offer the tightest tolerances when compared to original equipment blades across all makes. These blades are equivalent to John Deere GX20249, GX20433, GX20819, GY20567; Oregon 91-139; Rotary 10635; and Stens 330-615. Model Number: B1JD6015
