8TEN LawnRAZOR Mower Blade Set for MTD 942-0677B Cub Cadet 942-0677A 742-0677A RZT54 RZT 54 inch (Notched High Lift)

What It Is

This is a set of three notched high-lift blades designed to replace OEM MTD/Cub Cadet blades on 54-inch zero-turn mowers. The aggressive lift profile improves grass clipping discharge and bagging performance, making it ideal for thick or damp grass.

Fitment & Compatibility

• Deck size: 54 inches (three blades, each ~18 inches long, with a 1-inch center hole and 7-point star drive).
• OEM cross-reference: MTD 942-0677B, Cub Cadet 942-0677A, 742-0677A. Also fits many RZT54 models (check your deck part number).
• Before buying: Measure your blade length (center hole to tip) and confirm the drive pattern (star vs. oval). Verify your deck’s spindle orientation—these are notched, so they require notched spindles. Check your mower’s manual or existing blade part number.
• Not compatible: With 54-inch decks using a different blade pattern (e.g., oval hole or non-notched spindles).

Key Things to Know

• Lift vs. mulching: High-lift blades create strong airflow for bagging but leave a rougher cut if you mulch. Swap to mulching blades if you always mulch.
• Installation: Easy if you have a blade removal tool and torque wrench (tighten to 70-80 ft-lbs). The star drive fits securely, but ensure the notch aligns with the spindle tab.
• Durability: 8TEN blades are heat-treated steel; they hold an edge well but may dull faster in sandy soil. Check for balance after sharpening.
• Common gotcha: Some users report the blades are slightly thinner than OEM—fine for residential use, but not ideal for commercial mowing or heavy debris.

Should You Buy It

Buy these if you have a 54-inch Cub Cadet or MTD zero-turn with notched spindles, want better bagging or discharge, and are okay swapping blades seasonally. Skip them if you primarily mulch or need commercial-grade thickness.
