Troy-bilt 742-0742a-0637 Lawn Mower Blade 22 in

Product Description

The TROY-BILT 742-0742a-0637 is a replacement cutting blade designed for 22-inch deck lawn mowers. This OEM-style blade mounts to the spindle assembly and delivers the cutting action required for clean, even grass trimming across a standard residential mowing deck. The MTD Star designation refers to the center hole pattern used for spindle fitment. Licensed HVAC techs do not install this part — it is serviced by equipment technicians and knowledgeable homeowners maintaining walk-behind mowers in residential lawn care applications.

This blade is suited for walk-behind mowers equipped with a 22-inch cutting deck using the MTD Star center mounting configuration. It is a direct-replacement part for TROY-BILT branded outdoor power equipment and is consistent with MTD-platform mower designs that share the same deck and spindle geometry. Typical installation occurs during seasonal maintenance, after blade impact damage, or when blade wear reduces cutting performance.
