8TEN LawnRAZOR Mulching Blade Set for Honda HRC216K2 HRC216K3 Walk Behind 72531-VK6-010 72511-VK6-000

What It Is

This 8TEN LawnRAZOR mulching blade set is designed for the Honda HRC216K2 and HRC216K3 walk-behind mowers. It replaces OEM part numbers 72531-VK6-010 and 72511-VK6-000, delivering fine grass clipping mulching for commercial-grade residential use.

Fitment & Compatibility

Before buying, confirm your mower deck is 21 inches—these blades fit Honda models with that deck size. Verify your mower’s model number (HRC216K2 or HRC216K3) on the chassis tag. The set includes two blades, each with a 3.25-inch center hole and a 4.5-inch blade length from center to tip. They are aftermarket replacements for OEM Honda blades, so check that your current blade mounting pattern matches (two blades, opposed orientation). Measure your old blade’s width (1.75 inches) and thickness (0.1875 inches) to ensure compatibility—these match Honda’s spec.

Key Things to Know

• Quality: 8TEN uses heat-treated steel, but some users report slightly less durability than OEM Honda blades—expect 2-3 seasons of regular use.
• Installation: Simple bolt-on swap with a 15/16-inch socket; torque to 40-50 ft-lbs. No special tools needed, but always disconnect the spark plug first.
• Balance: These blades come pre-balanced, but check with a blade balancer after installation—unbalanced blades cause vibration and uneven cuts.
• Gotcha: The lift angle is slightly lower than OEM, which may reduce bagging performance. Best for mulching only, not side-discharge or bagging.

Should You Buy It

If you own a Honda HRC216K2 or K3 and primarily mulch clippings, this set is a solid budget-friendly option at $35.95—about half the cost of OEM blades. It’s not for heavy commercial use or if you need perfect bagging performance, but for homeowners maintaining a medium-sized lawn, it delivers good mulching results with straightforward installation.
