Wadoy 72511-VK6-000 & 72531-VK6-010 Lawn Mower Blades Compatible with Hondaa HRC216K2 HXA, HRC216K2 PDA, HRC216K3 HXA, HRC216K3 PDA3 Mulching Blade Set（Not Fit for VH7-000 Blade） | Mulching Blade Set

What It Is

This is a set of two mulching blades designed to replace the OEM Honda blades (part numbers 72511-VK6-000 and 72531-VK6-010) on select Honda HRC216 commercial walk-behind mowers. The curved, multi-surface design cuts grass into fine clippings that can be left on the lawn.

Fitment & Compatibility

• Exact models: Honda HRC216K2 HXA, HRC216K2 PDA, HRC216K3 HXA, HRC216K3 PDA3. Does not fit models using the VH7-000 blade (check your current blade part number).
• Deck size: 21-inch cutting deck only. Measure your blade length – OEM is 21 inches tip-to-tip. Center hole is 1 inch (standard Honda pattern).
• OEM vs aftermarket: These are a direct replacement for the two listed Honda OEM blades. Not compatible with Honda’s GCV or other engine series.
• What to check before buying: Remove one blade and verify the part number stamped on it. Measure blade length, center hole diameter, and ensure you have a two-blade (not single-blade) setup. Confirm your mower model number from the data plate under the seat or on the deck.

Key Things to Know

• Material: Heat-treated steel, balanced for reduced vibration. Reviews note they feel slightly lighter than OEM but cut well.
• Installation: Straightforward bolt-on job. Requires a 15/16-inch socket (or 24mm) and torque to 35–45 ft-lbs. Use a blade stop or wedge to prevent spinning. Sharpening is possible but not recommended more than twice.
• Mulching performance: Works best with dry, short grass. Wet or tall grass may clump. The lift is moderate – good for bagging or side discharge, but optimized for mulching.
• Common gotcha: These blades are sold as a set of two; ensure your deck uses both. Some HRC216 models have a single long blade – verify your setup before ordering.

Should You Buy It

If you own a Honda HRC216K2 or K3 with the two-blade system and need an affordable, solid mulching blade set that matches OEM fitment, this is a good value. Not ideal for heavy-duty commercial use or if you prefer OEM-only parts, but fine for residential or light commercial mowing at half the OEM price.
