What It Is

This 21.23-inch replacement blade set is designed for 42-inch decks on Cub Cadet Enduro XT1-LT42, XT2-LX42, and Ultima ZT1 lawn tractors. It cuts grass on residential properties and is a direct aftermarket alternative to OEM part numbers 742P05177A-X, CMXGZAM110202, 490-110-Y202, and 742-05177A-X.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 42 inches (not 46 or 50). Check your current blade length—these are 21.23 inches long with a 1-inch center hole and 5-point star drive. They fit Cub Cadet models listed in the title but will not work on older 42-inch decks using a different spindle or blade pattern (e.g., round center hole). Verify your OEM part number matches one of the listed cross-references. If your tractor uses a different blade mounting system (like a keyed or offset hole), these won’t fit.

Key Things to Know

• Quality: Made from heat-treated steel; reviews note decent durability for residential mowing, but not as thick as OEM blades. Expect to sharpen or replace after one season of heavy use.
• Installation: Straightforward swap—use a socket wrench and block the blade to prevent spinning. Torque bolts to 70-90 ft-lbs. No special tools required.
• Common Gotcha: These are sold as a set of two blades (not three). If your 42-inch deck uses three blades (like some AYP/MTD designs), these won’t work. Confirm your deck spindle count before ordering.
• Balance: Check balance after installation; some users report minor imbalance out of the box. A simple blade balancer ($10) can save vibration issues.

Should You Buy It

Buy these if you own a Cub Cadet XT1-LT42, XT2-LX42, or ZT1 with a 42-inch deck and want an affordable, direct-fit replacement for residential mowing. They’re a solid value for the price, but skip them if you need OEM durability for commercial use or a thicker blade for rough, rocky terrain.
