LawnRAZOR Blade for Cub Cadet MTD XT1-LT42 XT2-LX42 42-Inch Deck 742-05177 742P05177 490-110-C191 Ultra High Lift 2 Pack

What It Is

The LawnRAZOR Ultra High Lift Blade (2-pack) is a direct-replacement mulching/performance blade for 42-inch deck Cub Cadet XT1-LT42 and XT2-LX42 lawn tractors. It’s designed for heavy grass, bagging, or improved airflow in high-cut conditions.

Fitment & Compatibility

• Deck size: 42-inch (measured cutting width, not deck shell).
• Models: Cub Cadet XT1-LT42, XT2-LX42 (also fits some MTD-built units with 42” decks).
• OEM part cross: 742-05177, 742P05177, 490-110-C191.
• Measurements: Blade length 20.5”, center hole 7/8” round, thickness 0.25”.
• Check before buying: Confirm your deck spindle pattern (oval or round? this is round hole only). Verify blade offset (this is a high-lift, not standard low-lift). Not for 46” or 50” decks.

Key Things to Know

• Quality: High-lift design moves more air, improving bagging and discharge, but creates more drag and may need more engine power.
• Installation: Moderate difficulty. Use a torque wrench (40-50 ft-lbs) and anti-seize on spindle bolts. Sharp edges – wear gloves.
• Gotcha: High-lift blades can cause rough cutting in very dry, dusty conditions (they lift debris). Best for damp grass or bagging.
• Pack size: 2 blades – enough for one full deck swap (no need for a third center blade on 42” decks with 2-blade spindles).

Should You Buy It

Buy if you need better bagging or discharge performance on a 42” Cub Cadet/MTD tractor and don’t mind slightly increased engine load. Skip if you mostly cut dry, short grass (a standard lift blade is smoother) or have a 46”/50” deck – this won’t fit.
