50 Inch Deck Mower Blade Replacement 6 Pack - Durable Cut Performance

Our review of these 50 in deck mower blades finds them best suited to owners of 50 in MTD, Cub Cadet and Troy-Bilt zero turn and lawn tractor decks who want a cost-effective blade refresh. The biggest reason to buy is straightforward: they replace common OEM numbers (742-05052, 942-05052, 942-05052A, 742-05052A, CMXGZAM110155) and match the 6 point star center hole pattern, so installation is simple for compatible machines. Out of the box the blades show a sharp edge and solid heft, offering an immediate improvement in cutting performance for many mowing conditions.

Key Features

• OEM compatibility: Replaces multiple OEM numbers so users can fit many 50 in MTD, Cub Cadet and Troy-Bilt decks without hunting for an exact original part.
• Exact center fit: The 6 point star center hole matches the factory spindle interface to reduce play and make installation straightforward.
• Cut dimensions: With a length of 17.25 in, width of 2.5 in and thickness of 0.156 in, these blades provide the profile expected for 50 in decks for predictable blade-to-deck clearance.
• Value pack: Sold as a 6 pack which is convenient for multi-blade zero turn decks or keeping spares on hand, lowering per-blade cost.
• Broad model fit: Listed compatibility includes many XT1, XT2, RZT and ZT series models, plus several Super Bronco and Mustang variants to cover a wide range of mowers.
• Support and warranty: Backed by a one year warranty and seller support, giving buyers recourse if a blade is defective or has fit issues.

Who It's For

This pack is ideal for homeowners and small property managers who maintain zero turn mowers or lawn tractors with a 50 in cut and a 6 point star center spindle. It is especially useful for owners of post-2015 MTD, Cub Cadet and Troy-Bilt models who need a matched set for multi-blade decks or prefer keeping spare blades on hand for seasonal swaps.

Users who should look elsewhere include those with nonstandard or older deck spindle holes, or anyone requiring proprietary aftermarket features such as extended wear coatings or precision balanced specialty blades; for those needs a model-specific OEM specialty blade is a better option.
