KBZ 72511-VK6-000 and 72531-VK6-010 Lawn Mower Blades Fits for Hon-da HRC216K2 HXA, HRC216K2 PDA, HRC216K3 HXA, HRC216K3 PDA3 Mulching Blade Set

What It Is

This is a set of two mulching blades (OEM references 72511-VK6-000 and 72531-VK6-010) designed for specific Honda HRC216 commercial mower models. They cut grass into fine clippings that decompose quickly, eliminating bagging.

Fitment & Compatibility

Check your model number exactly. These fit:

• Honda HRC216K2 HXA
• Honda HRC216K2 PDA
• Honda HRC216K3 HXA
• Honda HRC216K3 PDA3

Critical measurements:

• Blade length: ~21 inches (center hole to tip)
• Center hole: 1-inch diameter with a 5-point star pattern (Honda-specific)
• Thickness: ~0.1875 inches

OEM cross-reference: 72511-VK6-000 (left blade) and 72531-VK6-010 (right blade). These are aftermarket replacements, not Honda genuine. Confirm your deck size is 21 inches—any other deck will not fit.

Key Things to Know

• Quality concerns: Rating is 3.3/5 with only 3 reviews—limited feedback. Some aftermarket blades may be thinner or less balanced than OEM.
• Installation: Requires a torque wrench. Honda spec is 40–50 ft-lbs. Use thread locker on blade bolts.
• Star pattern check: The 5-point star center must match your spindle. Aftermarket blades sometimes have slightly loose fitment here.
• Mulching vs. bagging: These are mulching blades—they won’t discharge well if you use a side-discharge chute. Keep blades sharp for proper mulching.

Should You Buy It

Buy these only if you need to save money over OEM Honda blades (typically $45–60/set) and you own one of the exact HRC216 models listed. If you mow commercially or want guaranteed balance/longevity, stick with OEM. For light residential use on a commercial mower, these are a budget-friendly option—but check fitment carefully before installing.
