3PCS 942-05052A Mower Blades for Cub Cadet 50 Inch Deck XT1 XT2 50 LT50 ZT1 ZT2 GT50 RZT50 LX50 MTD Troy Bilt 50" Zero Turn Enduro Lawn Mower 742-05052A High Lift 2-in-1 Blades(6 Point Star)

What It Is

This is a set of three high-lift 2-in-1 mower blades designed for 50-inch cutting decks on select Cub Cadet, MTD, and Troy-Bilt lawn tractors and zero-turn mowers. They are aftermarket replacements for OEM part numbers 942-05052A and 742-05052A, intended for bagging or side-discharge use.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 50 inches from blade tip to blade tip. These blades fit Cub Cadet XT1, XT2, LT50, ZT1, ZT2, GT50, RZT50, and LX50 models, plus MTD and Troy-Bilt 50-inch Enduro series zero-turn mowers. The mounting hole is a 6-point star (commonly called a “star center”) – measure your spindle’s drive hole shape to verify it matches. Blade length is 20.5 inches, width 2.5 inches, with a 0.25-inch thickness and a 1-inch center hole diameter. Always cross-reference your OEM part number (942-05052A or 742-05052A) against your mower’s manual to avoid spindle or clearance issues.

Key Things to Know

• Quality vs OEM: These are aftermarket blades; they may be slightly thinner or less durable than genuine Cub Cadet parts, but many users report them lasting a full season with regular use.
• Installation difficulty: Easy swap if you have a socket set and jack stands. Torque blade bolts to 70-90 ft-lbs. Use thread locker on bolts to prevent loosening.
• Common gotchas: High-lift blades create more suction – good for bagging, but can cause clumping in damp grass or leave scalping marks on uneven terrain. Not ideal for mulching.
• Balance check: Aftermarket blades sometimes arrive out of balance. Always balance them before installing to avoid vibration and spindle wear.

Should You Buy It

Buy this set if you need an affordable, direct-fit replacement for bagging or side-discharge mowing on a 50-inch Cub Cadet or compatible MTD/Troy-Bilt deck, and you don’t mind checking balance yourself. Skip it if you primarily mulch or want OEM-grade longevity – invest in genuine Cub Cadet blades instead.
