Replacement 72511-VK6-000(Lower) & 72531-VK6-010(Upper) Mulching Mower Blade Kit, Compatible with Hon da HRC216K2, HRC216K2 HXA, HRC216K3, HRC216K3 PDA, HRC216K3 HDAH Lwan Mower, 2 Blades

What It Is

This is a two-blade mulching kit (lower blade 72511-VK6-000 and upper blade 72531-VK6-010) designed specifically for select Honda HRC216 commercial mowers. It replaces the standard discharge blades to finely chop clippings for nutrient recycling, ideal for frequent mowing or clean mulching.

Fitment & Compatibility

• Exact models: Honda HRC216K2, HRC216K2 HXA, HRC216K3, HRC216K3 PDA, HRC216K3 HDAH. Double-check your mower’s model number on the deck sticker—HRC216 variants with different suffixes (e.g., K4) may not match.
• Deck size: Fits 21-inch cutting decks. Measure your blade length (should be ~21 inches tip-to-tip) before ordering.
• OEM vs aftermarket: These are aftermarket replacements for OEM Honda parts 72511-VK6-000 and 72531-VK6-010. They match the original design but are not Honda-branded.
• What to verify: Ensure your mower currently uses a two-blade mulching setup—some HRC216 models ship with a single blade. Check blade thickness (approx. 0.187 inches) and center hole diameter (20mm or 0.787 inches) to confirm fit.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (recommended 30-40 ft-lbs), and thread locker (Loctite) to prevent loosening. The blades are handed—upper and lower are different, so label them during removal.
• Mulching performance: Works best with sharp blades and dry grass. Damp or tall grass may clump under the deck; mow more frequently for optimal results.
• Common gotcha: These blades are thinner than OEM Honda blades (0.187 vs 0.250 inches). They cut well but may wear faster or bend on rocky terrain. Inspect regularly for damage.
• Balance check: Always balance after sharpening or installation to avoid vibration that can damage the spindle.

Should You Buy It

Buy this kit if you own a compatible HRC216 model and want an affordable mulching upgrade for cleaner, nutrient-rich clippings. It’s a solid value at $27.59, but skip it if you need heavy-duty durability for rocky yards or prefer OEM thickness.
