742P05086 High-Lift Lawn Mower Blade Set for 54" Zero-Turn Mower, Replaces 742-05086 CMXGZAM110194, Compatible with XT1-GT54 XT1-ST54 ZT1-54 ZT2-54 (3 Pack)

What It Is

This is a three-pack of high-lift lawn mower blades designed for 54-inch zero-turn mowers, intended to improve grass clipping discharge and bagging performance by creating stronger upward airflow. They replace OEM part 742-05086 and are compatible with Cub Cadet and similar models in the XT1, XT2, and ZT series.

Fitment & Compatibility

• Deck size: Only for 54-inch cutting decks. Measure your deck width to confirm.
• Model compatibility: Fits Cub Cadet XT1-GT54, XT1-ST54, ZT1-54, ZT2-54, and other models using OEM 742-05086 or CMXGZAM110194.
• OEM vs aftermarket: These are aftermarket replacements, not genuine Cub Cadet parts. Check blade length, center hole diameter, and thickness against your current blade (typically 18.25” long, 1” center hole, 0.25” thick).
• What to verify before buying: Remove one existing blade and measure length, width, and hole pattern. Also confirm your mower uses a three-blade set—some 54” decks use two blades.

Key Things to Know

• High-lift design improves bagging and side discharge but may reduce engine power slightly in thick, wet grass.
• Installation is straightforward—use a socket wrench and thread locker on the blade bolt. Torque to 70-90 ft-lbs (check your manual).
• Watch for balance issues—aftermarket blades can be slightly off. Check balance with a blade balancer before installing to avoid vibration.
• Replace in sets—mixing old and new blades can cause uneven cut and strain the spindle.

Should You Buy It

If you own a 54” Cub Cadet zero-turn and want better bagging or discharge performance without paying OEM prices, this set is a solid value. It’s best for homeowners who mow regularly and don’t mind a slight power draw in heavy grass. Skip it if you need exact OEM fit or have a different deck size.
