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

What It Is

This is a two-blade mulching kit (lower blade 72511-VK6-000 and upper blade 72531-VK6-010) designed to replace the factory blades on Honda HRC216 commercial-series mowers. It’s intended for mulching—chopping clippings fine and blowing them back into the turf—not for bagging or side-discharge.

Fitment & Compatibility

Before buying, confirm your mower’s model number is one of the following: HRC216K2, HRC216K2 HXA, HRC216K3, HRC216K3 PDA, HRC216K3 HXA. These are all 21-inch deck models. The blades are aftermarket replacements for OEM Honda part numbers 72511-VK6-000 and 72531-VK6-010. Measure your existing blades: lower blade should be roughly 21 inches long, upper blade shorter (about 16–17 inches). Center hole diameter is 1 inch, with a 5-point star drive pattern. If your deck uses a different blade retention system (e.g., a single flat washer and bolt), this kit won’t fit. Always verify deck serial number against Honda’s compatibility charts if you’re unsure.

Key Things to Buy

• Quality: Aftermarket blades, not OEM. Reviews note they’re slightly thinner than Honda originals but still durable for residential and light commercial use. Expect a bit less longevity under heavy daily cutting.
• Installation: Moderate difficulty. You’ll need to remove the center bolt and lower blade, then the upper blade. Use a blade stop or block of wood to prevent spinning. Torque lower bolt to 40–45 ft-lbs. Mark blade orientation before removal—they’re not interchangeable.
• Common Gotchas: The mulching design requires a clean, dry deck to work well. Wet grass will clump under the deck. Also, the blades are not reversible; replace when dull or nicked.
• Performance: Cuts fine and leaves a clean mulch pattern on dry, short grass. On tall or wet turf, you may need to slow down or double-cut.

Should You Buy It

Buy this kit if you own one of the listed Honda HRC216 models and want a budget-friendly mulching blade set that works well for regular residential mowing. Skip it if you need OEM durability for daily commercial use, or if your deck requires a different blade pattern or length.
