8TEN LawnRAZOR Blade Set for Cub Cadet LT1050 GT2050 50 Inch Deck MTD 742-04068 (Notched High Lift)

What It Is

The 8TEN LawnRAZOR Blade Set is a set of three notched high-lift blades designed for 50-inch cutting decks on select Cub Cadet LT1050 and GT2050 models. These blades replace OEM part 742-04068, intended for heavy lifting and improved grass discharge in tall or thick grass.

Fitment & Compatibility

• Deck size: Only fits 50-inch decks; verify your deck width before purchase.
• Models: Cub Cadet LT1050, GT2050, and other MTD-built 50-inch deck tractors using 742-04068 OEM blades.
• Measurements: Each blade is 19.75 inches long, 2.5 inches wide, with a 1-inch center hole and 0.25-inch thickness. Confirm your spindle mount matches (three-point star pattern, 5.5-inch center-to-center).
• Check: Compare your old blade’s length, hole size, and notch pattern. Notched high-lift blades require sufficient deck clearance—measure blade-to-deck clearance (minimum 1/2 inch) to avoid contact.

Key Things to Know

• Quality: Made from heat-treated steel, but some users report slightly thinner metal than OEM—inspect for bending after heavy use.
• Installation: Easy DIY job; use a blade removal tool or wrench. Torque bolts to 70–90 ft-lbs. Notched edge must face upward toward the deck.
• Gotchas: High-lift blades increase engine load and may reduce fuel efficiency. Not suitable for mulching or bagging unless your deck has a high-lift design.
• Noise: Louder than standard blades due to increased airflow—normal for high-lift style.

Should You Buy It

Buy this set if you need affordable, high-lift blades for a Cub Cadet LT1050 or GT2050 with a 50-inch deck and primarily cut thick or tall grass. Avoid if you prefer OEM durability or run a mulching setup—standard or mulching blades will be quieter and put less strain on the engine.
