50-Inch Mower Blades for Cub Cadet Ultima ZT1 ZT2 and Enduro XT1 XT2, Fits Riding Mowers and Zero-Turn Tractors, Replaces OEM 942-05052A 742-05052A, 6-Star Center Hole, High-Lift for Cleaner Cuts

What It Is

A set of three 50-inch high-lift mower blades designed for Cub Cadet Ultima ZT1, ZT2, and Enduro XT1, XT2 zero-turn and riding mowers. They replace OEM part numbers 942-05052A and 742-05052A, and the high-lift design improves airflow for cleaner, more even cuts in dense or tall grass.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch cutting deck (not 46 or 54 inches). These blades fit Cub Cadet Ultima ZT1, ZT2, and Enduro XT1, XT2 models with a 50-inch deck, plus select other riding mowers using the same OEM pattern. The center hole is a 6-star shape—measure your spindle’s star pattern to ensure it matches. They are aftermarket replacements for 942-05052A and 742-05052A; check your current blade’s part number on the stamped metal. Also verify blade length (approx. 16.5 inches each), thickness (0.25 inches), and that your deck uses three blades, not two.

Key Things to Know

• High-lift design increases vacuum for better grass clipping discharge, but may wear faster in sandy or rocky soil.
• Installation is straightforward: lift the mower, remove the old blade bolt (use a block of wood to hold the blade), and torque the new blade bolt to 40-50 ft-lbs.
• Balance check recommended: even with good reviews, aftermarket blades can be slightly off-balance; use a blade balancer to avoid vibration.
• Star fitment is critical: the 6-star center hole must align with your spindle’s drive pattern—if your OEM blade has a round or different star hole, these won’t work.

Should You Buy It

Buy these if you own a Cub Cadet with a 50-inch deck, need to replace worn or dull OEM blades, and want a cost-effective aftermarket option with strong user feedback. They’re ideal for homeowners who mow thick grass and want a cleaner cut, but skip them if your deck size differs or your spindle uses a non-star pattern.
