LawnRAZOR Blade for Cub Cadet MTD Craftsman XT1-LT42 XT2-LX42 Z5200 42-Inch Deck 742-05177-L 742P05177-L Low Lift 2 Pack

What It Is

The LawnRAZOR blade (742-05177-L / 742P05177-L) is a low-lift replacement blade for 42-inch decks on select Cub Cadet, MTD, and Craftsman lawn tractors and zero-turn mowers. It’s designed for standard mulching and bagging on flat, dry turf—not for heavy wet grass or thick brush.

Fitment & Compatibility

• Deck size: 42 inches (3 blades per set, each 15.75 inches long, center hole 1 inch, star pattern).
• Direct OEM replacement for Cub Cadet/MTD part numbers 742-05177-L and 742P05177-L.
• Fits models: XT1-LT42, XT2-LX42, Z5200, plus many other Cub Cadet, MTD, and Craftsman 42-inch decks using the same blade pattern.
• Check before buying: Measure your existing blade length (center hole to tip) and hole shape (star vs. oval). Confirm your deck is 42 inches—not 46 or 50. Verify the part number on your current blade or in your owner’s manual.

Key Things to Know

• Low lift: Produces less airflow than a high-lift blade, so it’s quieter and uses less engine power, but it won’t discharge wet grass as well. Best for dry, short grass.
• Installation: Easy swap with a socket wrench (5/8-inch or 3/4-inch bolt). Torque to 50-70 ft-lbs. No special tools needed.
• Common gotcha: The star center hole fits most Cub Cadet/MTD spindles, but some older Craftsman decks use a different hole pattern—measure before ordering.
• Quality: Heat-treated steel, balanced out of the box. Some users report slight wobble if the deck isn’t level—check blade alignment after install.

Should You Buy It

If you have a 42-inch Cub Cadet, MTD, or Craftsman tractor/zero-turn and need a budget-friendly low-lift blade for light mulching and bagging on dry lawns, this 2-pack is a solid choice. Skip it for heavy wet grass or if you need high-lift discharge—go with a standard OEM or high-lift blade instead.
