46" Lawn Mower Deck Blades Fits for Cub Cadet XT1-LT46 XT2-LX46 Craftsman Z5400 Z5450 T2400 T3000 Replaces OEM 742-05510 742-05573 742P05510 (High-Lift) 2 Pack

What It Is

This is a set of two high-lift 46-inch mower deck blades designed for cutting grass on residential zero-turn and lawn tractors. They are intended for owners of Cub Cadet XT1-LT46, XT2-LX46, and Craftsman Z5400, Z5450, T2400, T3000 models, replacing OEM part numbers 742-05510, 742-05573, and 742P05510.

Fitment & Compatibility

Before buying, measure your existing blade length (must be exactly 46 inches tip-to-tip) and verify the center hole diameter (typically 1-inch or 7/16-inch, but confirm on your spindle). Check that your deck is a standard 46-inch stamped or fabricated deck—not a 42-inch or 54-inch. The blades fit Cub Cadet XT1-LT46 and XT2-LX46, and Craftsman Z5400, Z5450, T2400, T3000. They are aftermarket replacements for OEM parts 742-05510, 742-05573, and 742P05510. Do not assume fit for other Cub Cadet or Craftsman models without cross-referencing your OEM part number.

Key Things to Know

• High-lift design improves grass clipping discharge and bagging performance, but may create more noise and vibration on light-duty decks.
• Installation is straightforward but requires a torque wrench; tighten blade bolts to 70-90 ft-lbs (check your deck manual). Use thread locker if bolts are loose.
• Check blade balance after installation—unbalanced blades cause deck vibration and uneven cuts. If needed, balance with a simple blade balancer.
• Sharpness out of the box is adequate for seasonal use, but these are not premium hardened steel; expect to sharpen every 10-15 hours of mowing under normal conditions.

Should You Buy It

Buy these if you own a compatible 46-inch Cub Cadet or Craftsman tractor and want a budget-friendly high-lift blade set for residential mowing, especially if you bag clippings. They are a solid value for the price, but if you need longer life or mulch better, consider OEM or premium aftermarket blades.
