8TEN LawnRAZOR Blade for Toro LX423 LX427 119-8456 42 Inch Deck Lawn Tractors (High Lift) 2 Pack

What It Is

The 8TEN LawnRAZOR High Lift Blade (2-pack) is a direct aftermarket replacement for Toro LX423 and LX427 lawn tractors with a 42-inch cutting deck. Designed for high-lift performance, it improves grass clipping discharge and bagging efficiency compared to standard blades.

Fitment & Compatibility

• Deck size: 42-inch cutting deck only; verify your deck measures exactly 42 inches.
• Model compatibility: Fits Toro LX423 and LX427, plus other Toro models using OEM part #119-8456 (check your owner’s manual or current blade part number).
• OEM vs aftermarket: This is an aftermarket blade, not Toro OEM. It matches the OEM dimensions (length, width, center hole) but may have slight finish differences.
• Measurements: Blade length is 21.5 inches, center hole diameter is 7/8 inch, and it uses a 5-point star drive adapter (common on Toro 42-inch decks). Confirm your blade mounting system matches before purchase.

Key Things to Know

• High lift = more power needed: The aggressive lift design increases air flow and bagging performance but can strain the engine on thick, wet grass. Keep blades sharp and mow at moderate speeds.
• Installation: Straightforward swap—remove the old blade, clean the spindle, and torque the bolt to 70-80 ft-lbs. Use a blade removal tool or block of wood to prevent spinning.
• Common gotcha: The star drive adapter must be in good condition; worn or plastic adapters may not engage properly with these aftermarket blades. Replace if cracked.
• Durability: Heat-treated steel holds an edge well but may dull faster than OEM if you hit rocks or debris. Inspect after each season.

Should You Buy It

Yes, if you own a Toro LX423 or LX427 with a 42-inch deck and want better bagging or discharge performance at a lower price than OEM blades. It’s a solid upgrade for homeowners who mow weekly and prioritize clean cuts. Avoid if you need OEM-exact fitment or mow in very wet, heavy conditions where high-lift blades can bog down the engine.
