8TEN LawnRAZOR Mower Blade for Cub Cadet RZT MTD LT2000 42 Inch Deck 942-04308 742-04308 742-04312 (High-Lift) 6 Pack

What It Is

The 8TEN LawnRAZOR Mower Blade is a high-lift, aftermarket replacement blade designed for 42-inch cutting decks on Cub Cadet RZT, MTD, and LT2000 series lawn tractors. It’s built for heavy lifting and discharge performance, making it ideal for thick or wet grass where bagging or side-discharge efficiency matters.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 42 inches. Measure your deck’s cutting width if unsure.
• OEM part numbers: Cross-references with Cub Cadet/MTD 942-04308, 742-04308, and 742-04312. Check your current blade’s stamped number.
• Blade measurements: Each blade is 21 inches long, 2.5 inches wide, with a 7-point star center hole and 0.25-inch thickness. Measure your old blade’s length and hole shape—standard for most MTD/Cub Cadet 42-inch decks.
• Model compatibility: Fits Cub Cadet RZT 50, RZT 54, LT2000, LT1042, and many MTD 42-inch models. Not for zero-turns with 46-inch or 54-inch decks.

Key Things to Know

• High-lift design: Creates strong airflow for bagging and side discharge but increases engine load slightly. Expect higher power draw in thick grass.
• Installation: Direct bolt-on for most compatible decks. Use a torque wrench—tighten to 70–90 ft-lbs. Check blade bolts for wear; replace if rounded.
• Quality: 8TEN uses heat-treated steel with a coated finish to resist rust. Edge retention is solid for the price, but avoid hitting rocks or stumps.
• 6-pack value: Priced at ~$10.67 per blade. Sharpening each set twice before replacement is typical for residential use.

Should You Buy It

If you need reliable, high-lift blades for a Cub Cadet or MTD 42-inch deck and want to save over OEM prices, this 6-pack is a strong choice. It’s best for homeowners with thick lawns who bag or side-discharge regularly. Avoid if you mulch exclusively—high-lift blades don’t chop clippings as finely as dedicated mulching blades.
