3 Pack 942-05052A High Lift Mower Blades with Nuts for Cub Cadet 50 Inch ZT1 RZT ZT2 XT1 RZT-L50 S50 GT50 LT50 LT50 LX50 Replaces 742-05052A for MTD Troy-Bilt Craftsman Lawn Tractors

What It Is

This is a 3-pack of high-lift mower blades (model 942-05052A) designed to replace the OEM 742-05052A on Cub Cadet 50-inch zero-turn and lawn tractors, plus compatible MTD, Troy-Bilt, and Craftsman models. High-lift blades create stronger airflow to lift grass for a cleaner cut and better bagging, ideal for tall or damp grass.

Fitment & Compatibility

• Deck size: Only fits 50-inch cutting decks. Measure your deck width before ordering; these won’t work on 42-inch or 54-inch decks.
• Models confirmed: Cub Cadet ZT1, RZT, ZT2, XT1, RZT-L50, S50, GT50, LT50, LX50. Also fits many MTD, Troy-Bilt, and Craftsman tractors with a 50-inch deck that use OEM part 742-05052A.
• OEM vs aftermarket: These are aftermarket replacements, not genuine Cub Cadet. Check blade thickness, center hole size (typically 1-inch), and overall length (likely 18 inches) against your current blades.
• What to verify: Look up your mower’s model number (on deck or frame) and cross-reference with 742-05052A or 942-05052A. The nuts included are standard 5/16-24, but confirm your spindle threads match.

Key Things to Know

• Installation: Easy bolt-on job with basic tools (socket and torque wrench). Torque nuts to 75-85 ft-lbs. Use thread locker if not included.
• Lift vs standard: High-lift blades improve bagging and clipping dispersal but increase engine load and can throw debris. Not ideal for mulching unless your deck has a mulch kit.
• Durability: These are hardened steel but not as thick as OEM. Expect 20-30 hours of use before dulling, depending on grass conditions. Sharpen or replace as needed.
• Common gotcha: Ensure blades are mounted with the lift wings facing upward (toward deck). Reversing them will cause poor cut and vibration.

Should You Buy It

If you own a 50-inch Cub Cadet or compatible MTD/Troy-Bilt/Craftsman and want better bagging or lift for tall grass, this 3-pack is a solid budget option. It’s not for mulching or heavy commercial use, but for home lawn care at $25.99, it’s a good value. Double-check deck size and spindle nut thread first.
