8TEN LawnRAZOR 18.5" Ultra High-Lift Mower Blade 3-Pack for 54" Decks — 6-Point Star Fit, OEM-Style

The 8TEN LawnRAZOR Ultra High-Lift 18.5" mower blade 3-pack is a direct-fit replacement designed to restore lift, discharge and bagging performance for 54-inch decks using MTD/ Cub Cadet/ Troy-Bilt compatible spindles.

When your mower’s cut quality or bagging efficiency drops, worn or bent blades are often the cause. These 8TEN LawnRAZOR blades reproduce the original blade geometry and lift profile so collectors and rear discharge systems keep working as intended. Each blade in this three-pack is stamped to match common OEM center hole patterns and thickness for a straightforward swap on many 54" residential and commercial lawn tractors.

Which machines will these blades fit?

These blades are built to match a broad list of 54-inch-deck tractors from popular brands. They are compatible with many Cub Cadet, MTD, Troy-Bilt, Craftsman, Huskee and other machines that use the 6-point star center hole and similar blade dimensions.

• Fits Cub Cadet models: SLTX1054, SLT1554, RZT-S54, RZT-L54, RZT54, LGTX1054, LGT1054, GTX1054, GT1554, GT1054

• Matches OEM part numbers including 742-0679, 942-0679 and related 742/942 series

What are the blade specifications and why they matter?

Each LawnRAZOR blade measures 18.5 inches long, 3 inches wide and 0.1875 inches thick, with an ultra high-lift profile. That combination produces a strong upward airflow that helps lift grass for a cleaner cut and moves clippings into the mower’s collection or discharge system more effectively.

• Length: 18 1/2" — matches standard 54" deck blade span
• Width: 3" and thickness 0.1875" — balances rigidity and clearance
• Center: 6-point star hole — fits specified spindle mounts
• Lift type: Ultra High-Lift with solid foil — optimized for bagging and discharge

How do I install these blades and what should I check first?

Installation is a routine task for most DIYers but requires safety precautions. Always disconnect the spark plug, raise and support the mower safely, and use the correct socket for the spindle nut. Verify blade orientation and torque to the manufacturer’s spec for secure, balanced operation.

• Disconnect spark plug and stabilize mower before starting
• Compare new blade center hole and mounting pattern to old blade
• Install cutting edge orientation as originally mounted (leading edge forward)
• Tighten to your deck’s recommended torque and check blade balance

Will these blades improve mowing results or just replace worn parts?

Replacing dull, bent or undersized blades with properly fitted LawnRAZOR blades restores airflow and cutting geometry, which usually yields noticeably better cut quality and bagging performance. While blades don’t change engine power, correct lift and sharpness let your mower reach intended performance levels again.

• Sharper edges and correct lift reduce tear and striping
• Improved airflow helps bagging systems collect more clippings
• Proper thickness resists premature bending or fatigue
• Sold as a 3-pack to service multiple spindles or keep spares on hand

Who is this for: The 8TEN LawnRAZOR 18.5" Ultra High-Lift 3-pack is aimed at homeowners and lawn-care pros running 54-inch deck tractors from Cub Cadet, MTD, Troy-Bilt, Craftsman and similar brands who need a reliable, OEM-compatible blade replacement. Choose this set if you want like-for-like dimensions, a high-lift profile for better bagging and a three-blade supply for complete deck service or future replacement.
