Honda Genuine OEM Blade Set 72511-VR8-M00 and 72531-VR8-M00 for HRN216 Series Lawn Mowers

What It Is

This is the official Honda OEM blade set for the HRN216 series walk-behind mowers, consisting of two separate blades (part #72511-VR8-M00 for the left and #72531-VR8-M00 for the right) that work together in a twin-blade cutting system. Designed for mulching and bagging on residential lawns, it replaces worn blades to restore clean cuts and prevent grass tearing.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 21-inch Honda HRN216 decks (e.g., HRN216VKA, HRN216VLA, HRN216VMA). Not compatible with HRX, HRR, or other Honda series.
• Model verification: Look at your mower’s serial number plate or owner’s manual to confirm “HRN216” is in the model number.
• OEM vs. aftermarket: These are genuine Honda parts, not generic replacements. They match factory dimensions exactly—no need to measure bolt patterns or offset if your mower is an HRN216.
• Bolt hardware: The blades use two 5/16-inch bolts (not included). Reuse your existing bolts if they’re in good shape, or buy new ones (Honda part #95701-06040-00) to prevent stripped threads.

Don’t assume fitment for non-Honda mowers—this set is strictly for HRN216 models.

Key Things to Know

• Quality: Heat-treated steel with a factory-balanced edge. Expect 25–40 hours of cutting life on typical lawns before dulling.
• Installation difficulty: Easy—requires a socket wrench (10mm or 13mm, depending on bolt size), a block of wood to jam the blade, and 10 minutes. Torque bolts to 30–35 ft-lbs.
• Common gotcha: The blades are handed (left vs. right). The curved side must face up toward the deck, and the longer cutting edge goes outward. Mixing them up causes vibration and poor cut.
• Sharpening vs. replacement: Don’t sharpen these—the heat-treating can be ruined. Replace when nicked or rounded.

Should You Buy It

Yes, if you own an HRN216 mower and want a guaranteed fit, consistent cut quality, and no balancing hassle. At $41, it’s a premium price over generic $15–20 sets, but you avoid vibration, uneven wear, and premature deck damage. Skip it only if you’re on a tight budget and willing to risk aftermarket fitment issues.
