8TEN LawnRAZOR Blade Kit for HRR216K9 HRR216K10 HRR216K11 21-Inch Decks 72531-VH7-000 72511-VL0-S00

What It Is

The 8TEN LawnRAZOR Blade Kit is a set of three high-lift replacement blades designed for Honda HRR216K9, HRR216K10, and HRR216K11 21-inch walk-behind mowers. It’s built for residential use where superior grass clipping discharge and bagging performance are needed.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 21-inch Honda decks. Measure your blade tip-to-tip if unsure.
• Model numbers: Confirmed fit for HRR216K9, HRR216K10, HRR216K11. Not for other HRR216 variants (e.g., K8 or K12) without checking blade shape and center hole size.
• OEM cross-reference: Replaces Honda part numbers 72531-VH7-000 and 72511-VL0-S00. Center hole is 1-inch diameter; blade length is 21 inches. Aftermarket, but direct-fit—no adapters needed.

Key Things to Know

• High-lift design: Curved blade tips create strong upward airflow for better bagging and side discharge, but increase engine load slightly. Not ideal for mulching unless you swap to a mulching blade.
• Installation: Straightforward with a socket wrench and torque wrench (recommended: 35-45 ft-lbs). Blades come with a center bolt, but reuse your original hardware if it’s in good condition.
• Balance: Pre-balanced out of the box, but check with a blade balancer after sharpening to avoid vibration.
• Sharpness: Factory edge is sharp but may need a quick hone after first use if you hit debris. Not hardened steel—resharpening is easy with a file.

Should You Buy It

If you own a compatible Honda HRR216 and want a cost-effective, direct-fit blade that maximizes bagging and discharge performance without paying OEM prices, this is a solid choice. Avoid if you primarily mulch—look for a dedicated mulching blade instead.
