50 Inch Deck High-Lift Mower Blades Fit for Cub Cadet ZT1 ZT2 XT1 XT2 LT50 GT50 RZT Troy-Bilt Super Bronco Mustang XP 50 Mower Replaces OEM 742-05052A 942-05052A with 6 Point Star 3 Pack

What It Is

This is a set of three high-lift mower blades designed for 50-inch cutting decks on select Cub Cadet, Troy-Bilt, and Roper-brand zero-turn and lawn tractors. High-lift blades create stronger airflow to lift grass for a cleaner cut and better bagging, making them ideal for tall or damp grass, but less suited for dusty or sandy conditions.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck and uses a 6-point star center hole (not a keyed or round hole). These blades replace OEM part numbers 742-05052A and 942-05052A. They fit Cub Cadet ZT1, ZT2, XT1, XT2, LT50, GT50, RZT series, plus Troy-Bilt Super Bronco and Mustang XP 50 models. Measure your existing blade length—these are 20.5 inches long, 2.75 inches wide, with a 0.25-inch thickness and a 0.625-inch center hole. If your deck uses a different spindle pattern or blade length, these will not work.

Key Things to Know

• Installation difficulty: Easy—remove the old blade, clean the spindle, and torque the center bolt to 70-80 ft-lbs. Use a blade removal tool or block the blade to prevent spinning.
• Quality: These are aftermarket blades, not OEM. They are made from heat-treated steel and should last a season with normal use, but may dull faster on rocky or sandy lawns.
• Common gotcha: The 6-point star must align perfectly with your spindle. Some Cub Cadet spindles use a 5-point star—verify before buying.
• Performance: High-lift blades increase engine load and may cause more vibration if not balanced after installation. Always check balance with a blade balancer.

Should You Buy It

Buy these if you own a 50-inch Cub Cadet or compatible Troy-Bilt mower, need a cost-effective replacement for worn OEM blades, and prioritize cutting and bagging performance over longevity in abrasive conditions. Avoid if your deck is smaller than 50 inches, uses a different spindle design, or if you mow in very sandy or dusty areas where standard blades last longer.
