742-04308 Mower Blades 42in Deck Replacement - Reliable Cut

In this review the 742-04308 mower blades are evaluated for owners of 42in deck riding mowers who need a straightforward, reliable replacement. The bottom line: these two-pack blades deliver sharp cutting edges and a secure fit for compatible Cub Cadet, Troy-Bilt and Craftsman models, making them a practical choice when the original blades wear out. The review focuses on real-world fit, cutting quality and ease of installation so a mower owner can decide quickly whether these blades match their spindle pattern and part number before buying.

Key Features

• Compatibility check: The listing emphasizes verifying model, part number and spindle type so buyers avoid ordering the wrong blade for their 42in deck.
• Broad model fit: These blades are compatible with many Cub Cadet, Troy-Bilt and Craftsman 42in tractors, covering common part numbers used by MTD and Toro.
• Durable construction: Heavy duty metal and a 6-point star center hole design provide a secure connection to matching spindle hubs for consistent operation.
• Ready to use: The pair ships already sharpened so users can reinstall and mow immediately without additional work.
• Standard dimensions: At about 21-1/4in long, 2.45in wide and 0.157in thick, the blades match common replacement sizes for 42in decks.

Who It's For

The blades are best for owners of Cub Cadet XT1-LT42 or XT2-LX42, Troy-Bilt Bronco or Pony 42, and Craftsman LT1500 style mowers who confirm a 6-point star spindle and one of the listed part numbers. If a mower uses the 942-04308, 742-04308 or similar MTD/Troy-Bilt part numbers, these blades are a cost-effective replacement that installs easily.

Shoppers who are unsure about their spindle hole shape, have uncommon model years, or need specialty mulching or high-lift blades should look elsewhere until they verify exact fit and function. The listing itself asks buyers to double-check hole shape and dimensions before ordering.
