8TEN LawnRAZOR Blade Set for MTD Cub Cadet RZT L46 46 inch 942-04290 942-04244 742-04244 942-04244A (Notched High Lift)

What It Is

The 8TEN LawnRAZOR Blade Set is a high-lift, notched blade set designed for 46-inch MTD and Cub Cadet zero-turn mowers, optimized for superior grass clipping discharge and bagging performance in thick or wet conditions.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch cutting deck and accepts three blades with a 1-inch center hole and 3.25-inch center-to-center notch spacing. This set directly replaces OEM part numbers 942-04290, 942-04244, 742-04244, and 942-04244A. It fits Cub Cadet RZT L46 and similar MTD-built models (e.g., RZT 50, LX46). Measure your existing blade length (should be 18 inches) and notch pattern—the notched high-lift design is specific to decks with a center discharge or bagger chute. Verify your spindle bolt size (usually 5/8-inch) and torque spec (typically 70-90 ft-lbs). Not compatible with standard or low-lift decks.

Key Things to Know

• Quality & durability: Made from 5/16-inch thick heat-treated steel with a hardened edge; holds up well against rocks and roots, but inspect after heavy use for bending.
• Installation difficulty: Easy to swap with basic tools (socket wrench, torque wrench, blade removal tool). Use a blade balancer after install to avoid vibration.
• Common gotcha: The high-lift design increases engine load and can throw clippings farther—ensure your deck is clean and your bagger is attached securely. Not ideal for mulching; use only for discharge or bagging.
• Fitment check: Always measure your old blade’s length, hole size, and notch alignment—some MTD decks use a different notch pattern (e.g., 2.5-inch center-to-center).

Should You Buy It

Buy this set if you need a durable, high-performance replacement for your MTD/Cub Cadet 46-inch deck that prioritizes bagging or side discharge over mulching. It’s a solid value at $29.95 with strong user ratings, but skip it if you primarily mulch or have a non-MTD deck.
