Detailed Review
The MaxPower 331528B mulching blade is a replacement cutting component designed for 21-inch walk-behind mowers. Made in the USA, it provides a direct swap for worn or damaged factory blades on a wide variety of machines from MTD, Cub Cadet, Troy-Bilt, and Craftsman.
This blade features a distinct bow tie center hole configuration paired with outside holes measuring 5/16 inches in diameter, spaced 2.5 inches center-to-center. It is built to replace several common OEM numbers, including 742-0741, 742-04276, 942-0741, and Craftsman CMXGZAM100067, making it an accessible maintenance option for homeowners maintaining compatible equipment.
During manufacturing, the blade is sharpened and then finished with a protective powder coating. This layer safeguards hands during handling and installation, wearing away naturally during the initial cut to expose the precision sharpened edge underneath.
Because fitment is specific, this blade will not work on decks requiring round center holes or different cutting widths. Owners must verify their existing blade OEM number and mounting pattern before purchasing, as it is limited to specific series such as Cub Cadet CC, SC, and S/SR lines, or Troy-Bilt TB, Tru-Cut, Tuff Cut, and Pro-Cut models.
Verdict: The MaxPower 331528B is a dependable, direct-fit replacement for anyone maintaining a compatible 21-inch mower. If your machine matches the bow tie pattern and listed OEM part numbers, it delivers a straightforward installation with a factory-sharpened edge.
