Decks, Set of 6","description":"Sunbelt B1SC3802 21-in. XHT Lawn Mower Blades for 61-in. Decks, Set of 6 are designed for heavy-duty use with Ferris, Scag, Wright, Exmark, and Toro commercial mowers featuring 61-inch decks. These blades measure 21 inches long, 2-1\/2 inches wide, and are .197 inches thick with a 5\/8-inch diameter center hole. Featuring a medium lift notched design, this set includes six blades crafted from Sunbelt's patented Marbain® heat-treated steel, which delivers extreme hardness and toughness. This advanced material enhances resistance to bending and impact damage, resulting in a cutting edge that remains sharper longer—approximately 25% to 40% harder than standard mower blades. These XHT blades provide the tightest tolerances when compared to original equipment blades and are equivalent to a wide range of part numbers across several brands, ensuring compatibility and reliable performance.\n\nModel Number: B1SC3802","brand":"Sunbelt","offers":[{"title":"Default Title","offer_id":47902656561315,"sku":"B1SC3802M6","price":111.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/f75dd38cbbcb37db36f3d9be120c191e1e2255a5_B1SC3802M6_1_H.png?v=1784359340","url":"https:\/\/www.hartvillehardware.com\/products\/sunbelt-b1sc3802-21-in-xht-lawn-mower-blades-for-61-in-decks-set-of-6","provider":"Hartville Hardware","version":"1.0","type":"link"}
