8TEN LawnRAZOR Blade for Cub Cadet MTD XT2-LX46 XT1-LT46 ZTS1-46 46-Inch 742-05510 742P05510 742-05573 Ultra High Lift 2 Pack

What It Is

This is a set of two ultra-high-lift replacement blades for 46-inch Cub Cadet and MTD lawn tractors. Designed for bagging, mulching, or side-discharge cutting on larger properties, the aggressive lift profile pulls grass upward for a cleaner cut and better debris evacuation.

Fitment & Compatibility

Before buying, verify three things: deck size must be exactly 46 inches (blade length is 20.5 inches, with a 5-point star center hole and 0.5-inch diameter). Model fit includes Cub Cadet XT2-LX46, XT1-LT46, ZTS1-46, and many MTD 46-inch decks. OEM cross-references are 742-05510, 742P05510, and 742-05573. Check your current blade’s part number or measure your blade—if it’s a different length or hole pattern, this won’t fit. Aftermarket, but built to OEM spec—no adapter needed.

Key Things to Know

• Installation is straightforward: use a torque wrench to 70-90 ft-lbs. No special tools beyond a socket and breaker bar.
• Ultra-high lift means better bagging and discharge, but it creates more drag and may slightly reduce engine RPM on thick, wet grass—skip if you only mulch.
• Material is hardened steel with a painted finish; expect good durability for residential use but not commercial abuse.
• Balance check is recommended before mounting—slight imbalances can cause vibration and bearing wear. File off any heavy side.

Should You Buy It

Yes, if you own a Cub Cadet or MTD 46-inch tractor and primarily bag or side-discharge. It’s a solid aftermarket upgrade that matches OEM performance at a fair price. Skip it if you only mulch or have a smaller deck—this blade is purpose-built for lift and airflow.
