Mower Blades 742P05510-X / 742P05510 for Cub Cadet / Troy-Bilt / MTD 46-Inch Deck

Overview

These 742P05510-X / 742P05510 aftermarket mower blades fit select Cub Cadet, MTD, Craftsman, and Troy-Bilt mowers using the newer 46-inch deck system with S-shaped blade centers.

This listing includes two mulching-style mower blades, providing one complete blade replacement for a supported two-blade 46-inch mower deck.

The supplier cross-references these aftermarket blades to 742P05510-X, 742P05510, 742-05510, and 490-110-C192. They use the same 23.25-inch S-shaped mounting path but may change the cutting and discharge characteristics compared with an original standard ultra-high-lift blade.

Important: Do not order by deck width or mower name alone. Confirm the original blade number, 23.25-inch blade length, S-shaped center pattern, and two-blade deck configuration before installation.
