21-Inch Twin Blades for Honda HRN216 Mower, Compatible with 06725-VR8-M00 72511-VR8-M00 72531-VR8-M00, Fits HRN216VKA HRN216VYA HRN216PKA, 21" Mulching Blades (2-Pack)

What It Is

This is a 2-pack of 21-inch twin mulching blades designed for Honda HRN216 series mowers. They replace worn factory blades to improve grass clipping shredding and recirculation, ideal for regular lawn maintenance where bagging isn’t the priority.

Fitment & Compatibility

Check deck size first: Your mower deck must be exactly 21 inches. Measure blade tip-to-tip if unsure—these are 21" long, 2.5" wide, with a 6-point star center hole and 0.5" diameter.

Model compatibility: Fits Honda HRN216VKA, HRN216VYA, and HRN216PKA. Also matches OEM part numbers 06725-VR8-M00, 72511-VR8-M00, and 72531-VR8-M00.

Aftermarket vs. OEM: These are genuine Honda blades, not third-party. No fitment adapters or modifications needed—direct bolt-on for listed models.

What to verify before buying: Check your mower’s model number (stamped under seat or on deck). Confirm you have the HRN216 series, not the HRR216 or HRX217—those use different blade lengths or hole patterns.

Key Things to Know

• Installation is straightforward with a socket wrench and blade removal tool (or a block of wood to hold blade). No special skills required.
• Sharpening vs. replacing: These are pre-sharpened; once dull, replace rather than sharpen—mulching blades lose effectiveness quickly when edge is gone.
• Common gotcha: Torque the center bolt to 35-40 ft-lbs. Overtightening can strip threads; undertightening can cause blade to loosen during operation.
• Mulching performance is good for dry grass but may struggle with very wet or tall grass—consider bagging or side-discharge in those conditions.

Should You Buy It

If you own an HRN216 and want OEM-quality mulching blades that fit without hassle, this 2-pack is a solid choice. It’s best for regular mowing on standard lawns where mulching is preferred. Skip it if you need bagging or lift blades, or if your deck isn’t exactly 21 inches.
