942-05052A 50" Mower Blades for Cub Cadet XT1 XT2 50 ZT1 ZT2 50 LT50 GT50 RZT50 MTD Troy Bilt 50 inch Deck Zero-Turn Enduro Series Lawn Mower 742-05052A 2-in-1 Blade/Medium Lift / 6-Pack

What It Is

A set of six 50-inch medium-lift, 2-in-1 (mulching/discharge) blades designed for Cub Cadet, MTD, and Troy-Bilt zero-turn and lawn tractors with 50-inch decks. Ideal for homeowners needing a direct replacement for OEM part 942-05052A or 742-05052A.

Fitment & Compatibility

• Deck size must be exactly 50 inches – confirm your deck width before ordering (measure blade tip to tip if unsure).
• Fits Cub Cadet XT1, XT2, ZT1, ZT2, LT50, GT50, RZT50 and Troy-Bilt Enduro Series zero-turns with 50-inch decks. Also compatible with MTD 50-inch models.
• OEM cross-reference: Replaces Cub Cadet/MTD part numbers 942-05052A and 742-05052A.
• Measure your old blades: Center hole diameter is typically 7/8-inch or 1-inch; verify your spindle’s hole size. Blade length should be 16.5 inches each (six blades total for a three-spindle deck).
• Check deck type: These are medium-lift blades – not high-lift (bagging) or low-lift (mulching only). If you have a bagger, these may not provide enough lift.

Key Things to Know

• Quality: Aftermarket blades, but rated 5.0 with solid reviews. Expect similar durability to OEM for residential use.
• Installation: Straightforward – remove old blades, clean spindles, torque to 30-50 ft-lbs. Use a blade removal tool to hold the spindle.
• Common gotchas: The 6-pack covers three spindles (two blades per spindle). Do not stack blades – each spindle gets one blade. Verify you are replacing all six, not just three.
• Balance: Aftermarket blades may need balancing; check with a blade balancer before installing to avoid vibration.

Should You Buy It

Buy if you own a 50-inch Cub Cadet or MTD zero-turn or lawn tractor and want a cost-effective 6-pack to replace worn or damaged OEM blades. Best for homeowners who mow regularly and prefer 2-in-1 mulching/discharge performance. Skip if you need high-lift blades for bagging or have a different deck size.
