8TEN LawnRAZOR Blade for Honda Walk Behind 21 inch Decks 72511-960-000 72511-VA2-690 72511-VA4-000 (High-Lift) 2 Pack

What It Is

The 8TEN LawnRAZOR Blade is a high-lift aftermarket replacement blade designed for Honda walk-behind mowers with 21-inch decks. It is intended for mulching and bagging, providing increased airflow to lift grass for a cleaner cut.

Fitment & Compatibility

Before buying, verify your mower deck is exactly 21 inches (measure diagonally from blade tip to tip). This blade replaces OEM Honda part numbers 72511-960-000, 72511-VA2-690, and 72511-VA4-000. It fits most Honda HRX, HRC, and HRS series models with these part numbers, but double-check your mower’s model number (e.g., HRX217) against Honda’s compatibility chart. Measure the blade length (21 inches), center hole diameter (usually 1 inch), and thickness (0.1875 inches) to match your original. Not for non-Honda decks or other sizes.

Key Things to Know

• High-lift design: Excellent for bagging and mulching, but creates more drag, which may reduce engine RPM on smaller engines or wet grass.
• Installation: Easy swap with a socket wrench; torque bolts to 30-40 ft-lbs. Use thread locker if bolts are loose.
• Balance: These blades are pre-balanced, but check with a blade balancer after sharpening to avoid vibration.
• Durability: Made from heat-treated steel, but sharpening may wear faster than OEM due to thinner profile.

Should You Buy It

If you need a cost-effective high-lift blade for bagging or mulching on a Honda 21-inch walk-behind, this 2-pack offers good value. It’s best for DIY users who want OEM-level performance without the OEM price, but ensure your deck is 21 inches and your model uses the listed part numbers. Skip it if you prefer standard lift or have a non-Honda mower.
