Product Description
Sold as a set of 3 aftermarket replacement blades for MTD / Cub Cadet / Troy-Bilt-family 21″ walk-behind mower applications using blade family 742-0741 / 942-0741 / 742-04100. Each blade measures 21″ in length and 2-1/4″ in width. The source file also provides 5/16″ outside-hole diameter and 2-1/2″ outside-hole center-to-center spacing. External search results consistently support this family as using a bow-tie center hole. Most 21″ applications in this family use 1 blade per mower, so this 3-piece listing should be understood as a bulk pack rather than a single mower set.

Installation Tips
Confirm your mower’s required blade quantity before ordering. Confirm the center-hole and outer-hole pattern match your original blade before installation. Always disconnect the spark plug wire before removing or installing blades. Replace bent, cracked, or badly worn blades immediately.
