XHT Mower Blades for 21-in. Decks, Set of 12 are designed specifically for mower decks with a 21-inch cut, making them an ideal replacement for MTD 21-inch Walk-Behind Mowers such as models 742-0741 and 942-0741. Each blade measures 21 inches in length and 2-1\/4 inches in width, featuring a 59\/64\" by 11\/16\" center hole and a medium lift, notched design. These blades utilize Sunbelt’s patented Marbain® heat-treated steel, which has been independently tested to deliver extreme hardness and toughness. This advanced treatment results in blades that are approximately 25% to 40% harder than standard lawnmower blades, ensuring a sharper cutting edge that lasts longer and resists bending and impact damage. The Sunbelt B1MA2417 blades provide tight manufacturing tolerances comparable to original equipment blades and are equivalent to MTD, Cub Cadet, White, Oregon, Rotary, and Stens part numbers.\n\nModel Number: B1MA2417","brand":"Sunbelt","offers":[{"title":"Default Title","offer_id":47902646599843,"sku":"B1MA2417M12","price":98.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/d426154049e59db9e44c0e3c48161af103c955cf_B1MA2417M12_1_H.png?v=1784358392","url":"https:\/\/www.hartvillehardware.com\/products\/sunbelt-b1ma2417-21-in-xht-mower-blades-for-21-in-decks-set-of-12","provider":"Hartville Hardware","version":"1.0","type":"link"}
