8TEN LawnRAZOR Blade for Honda HRR216K9 HRR216K10 HRR216K11 72511-VL0-S00 (Mulching) 2 Pack

What It Is

The 8TEN LawnRAZOR blade is an aftermarket mulching blade designed to replace the OEM Honda part 72511-VL0-S00. It’s intended for Honda HRR216K9, HRR216K10, and HRR216K11 walk-behind mowers, cutting grass into fine clippings for nutrient recycling.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., HRR216K9) is stamped on the deck or under the rear flap. This blade fits Honda 21-inch steel decks only—not aluminum or older HRR216 series. Measure your current blade: OEM length is 21 inches, center hole is 1-inch diameter with a 5-point star pattern. The 8TEN blade matches these dimensions but uses a universal star hole that may not align perfectly with Honda’s OEM spindle. If your mower has a different hole pattern (e.g., oval or round), this won’t fit. Check the part number on your old blade—72511-VL0-S00 is the direct reference.

Key Things to Know

• Quality concerns: With a 2.7/5 rating from only 5 reviews, reports of premature dulling, warping, or imbalance are common. Expect shorter lifespan than OEM Honda blades.
• Installation difficulty: Moderate. You’ll need a socket wrench and blade removal tool (or block the blade). Torque the center bolt to 30-40 ft-lbs—overtightening can warp the blade. Always sharpen or replace in pairs for balance.
• Mulching performance: The LawnRAZOR design has extra lift fins, but on damp or tall grass, it may clog or leave clumps. Works best with the mulch plug installed.
• Warranty: No known warranty; inspect for cracks or uneven edges before each use.

Should You Buy It

This blade is a budget option if you need a quick replacement and can accept lower durability and inconsistent performance. For reliable mulching and longer life, spend more on the genuine Honda 72511-VL0-S00 blade. Avoid if you mow thick, wet grass or want a balanced cut from a trusted brand.
