CUB CADET 490-110-F191 42" High-Lift Blade Set S-Shaped Mount Fab 42 ZTS1 ZT1 XT2 XT1 LX42 LT42B CMXGZAM110191 742P05576

What It Is

This is a set of three 42-inch high-lift blades designed for Cub Cadet zero-turn and lawn tractors. The high-lift profile increases airflow under the deck for superior bagging performance and cleaner cuts in tall or damp grass.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 42 inches. This set is OEM replacement for Cub Cadet models ZTS1, ZT1, XT2, XT1, LX42, LT42B, and CMXGZAM110191. It also replaces OEM part 742P05576. The blades use an S-shaped mounting pattern—check your existing blade’s center hole and mounting holes align with this design. Not compatible with universal or round-center blades. Verify your spindle spacing matches a 42-inch three-blade setup.

Key Things to Know

• Quality: OEM-grade steel with a hardened edge; holds sharpness longer than budget aftermarket sets.
• Installation: Straightforward bolt-on for most Cub Cadet decks—use a torque wrench to 55–65 ft-lbs. Lift deck safely and block wheels.
• Gotcha: High-lift blades increase engine load slightly; keep engine speed at full throttle during use. Not ideal for mulching—these are bagging/discharge optimized.
• Fitment check: Measure blade length from tip to tip: should be 21 inches per blade. Center hole diameter is 5/8 inch.

Should You Buy It

Buy this set if you own a compatible Cub Cadet 42-inch deck and prioritize bagging performance or clean discharge. It’s a direct OEM replacement, so no fitment guesswork, and the high-lift design handles thick grass better than standard blades. Skip it if you primarily mulch—look for a dedicated mulching blade set instead.
