CUB CADET 490-110-F108 High Lift Blade Set Star Mount 42" Deck RZT LTX EFI 42 ZT1 XT2 XT1 SX42 S42 LX42 CMXGZAM110108

What It Is

This is a set of three high-lift blades for Cub Cadet 42-inch decks, designed to increase airflow and suction for superior bagging and side-discharge performance. It’s ideal for mulching or collecting leaves and grass in heavy conditions.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 42 inches (measured blade tip to tip). This set fits Cub Cadet RZT, LTX, ZT1, XT2, XT1 Enduro Series, SX42, S42, LX42, and CMXGZAM110108 models with a star mount (5-point star center hole). Check your deck’s spindle mount type—star mount is not interchangeable with a standard oval or 5-point round hole. OEM part number is 490-110-F108; aftermarket equivalents may differ in thickness or balance. Measure your old blade length (20.5 inches typically) and verify the offset (1.5-inch lift) matches your deck’s clearance.

Key Things to Know

• Lift design: High-lift blades create strong suction but increase engine load and may throw debris; not ideal for dry, dusty conditions or if you prefer fine mulching.
• Installation: Requires a torque wrench (40-50 ft-lbs) and a star socket or adapter. Reverse thread on some spindles—check before tightening.
• Balance: Out-of-box balance can vary; always check with a blade balancer and file the heavy side if needed to avoid vibration.
• Durability: Heat-treated steel with a painted finish; expect 15-25 hours of heavy use before dulling. Sharpen with a file, but don’t overheat.

Should You Buy It

Buy this if you need aggressive bagging or side-discharge on a 42-inch Cub Cadet zero-turn or tractor with star mount spindles, and you’re willing to trade slightly higher power draw for superior lift. Skip if you only mulch or cut dry grass—standard lift blades will last longer and vibrate less.
