8TEN LawnRAZOR mower blades 42-inch High-Lift 2-Pack — direct-fit, heat-treated for MTD/Cub Cadet/Troy-Bilt

8TEN LawnRAZOR High-Lift mower blades replace OEM 742-04308 and 942-04308 to restore cutting performance on compatible MTD, Cub Cadet and Troy-Bilt 42" decks. These two high-lift blades are engineered as direct-fit replacements for a wide range of lawn tractors and zero-turn mowers that originally used Cub Cadet/MTD/Troy-Bilt OEM numbers 742-04308, 942-04308 and related part codes. Each blade is heat-treated and precision-drilled to match mounting holes, blade length and the high-lift profile that improves grass lift for cleaner cuts and better bagging on 42-inch decks.

Which machines will these blades fit?

How do these high-lift blades affect mowing results?

The high-lift profile increases upward airflow under the deck, lifting grass stems before cutting for a more even, taller cut and improved bag filling. That lift also helps reduce clumping when bagging and produces a cleaner mulch when used with compatible decks.

• Higher suction for neater bagging and discharge.
• Improved grass stand-up yields more uniform cuts.
• Minimizes uncut strips at the blade ends on 42" decks.
• Designed to support mulching or side-discharge setups depending on deck.

What are the build and fit details I should check before ordering?

Confirm your mower’s part number and blade length before purchase; these blades are pre-drilled to match standard 42" mower hole patterns and center dimensions used by the listed models. Also check blade orientation and rotation direction on your deck to ensure the high-lift lip faces upward when installed.

• Verify OEM compatibility list or compare hole spacing and center bore.
• Ensure blade length and end-to-end profile match your original blade.
• Install with the cutting edge and lift lip oriented per manufacturer instructions.
• Replace blades in matched pairs for balanced performance on two-blade decks.

How should I maintain these replacement blades for longest life?

Regular sharpening, balancing and inspecting for nicks or bends keeps the LawnRAZOR performing well. Replace blades if they show significant damage; rotating and reusing sharpened blades helps maintain even wear across the deck.

• Sharpen edges periodically to preserve cut quality.
• Balance blades after sharpening to prevent vibration.
• Inspect blade mounting bolts and torque to spec when reinstalling.
• Replace both blades at once on two-blade decks for balance.

This 2-pack is aimed at homeowners and lawn care pros who need an affordable, OEM-fit replacement for worn or damaged 42" mower blades. If you operate any of the compatible Cub Cadet, MTD or Troy-Bilt models listed and want to restore mowing performance or improve bagging and mulching, these 8TEN LawnRAZOR high-lift blades are a ready, direct-fit option. Always follow your mower manufacturer’s safety and installation guidelines when changing blades.
