Honda 08720-VH7-000 Mulching Blade Set

What It Is

The Honda 08720-VH7-000 is a set of three OEM mulching blades designed for select Honda 21-inch steel-deck walk-behind mowers. It replaces standard side-discharge blades to produce finer clippings for better lawn nutrition and a cleaner look.

Fitment & Compatibility

• Deck size: 21-inch cutting width only. Do not use on 20-inch or 22-inch decks.
• Model fit: Fits HRX217 (e.g., HRX217VKA, HRX217HYA, HRX217TDA) and HRS216 models with the 21-inch steel deck. Does not fit plastic-deck HRR216 or older HR214 models.
• OEM vs aftermarket: This is genuine Honda. Aftermarket blades (Oregon, MaxPower) cost less but may require rebalancing and can vary in thickness or hole alignment. Stick with OEM for guaranteed fit and balance.
• Measurement check: Blade length is 21 inches, center hole is 1 inch with a 5-point star drive. Verify your spindle’s star pattern matches—some aftermarket spindles use a round hole with a separate adapter.

Key Things to Know

• Installation difficulty: Moderate. Requires a socket wrench and blade-stopping tool (or wood block). Torque bolts to 30–35 ft-lbs—over-tightening can strip the spindle.
• Balance: Pre-balanced from Honda. Still, check balance after any sharpening or if you drop a blade.
• Common gotcha: These blades are directional—the “up” arrow must face the deck. Install upside-down and the mower will vibrate and cut poorly.
• Lift vs mulching: The mulching wing design is less aggressive than standard lift blades. On tall, wet grass, you may need to overlap passes to avoid clumping.

Should You Buy It

If you own a compatible Honda 21-inch steel-deck mower and want OEM-quality mulching performance with zero guesswork, this set is your best bet. It’s ideal for homeowners who mow weekly and value a clean, bag-free finish. Skip it if you only side-discharge or mow infrequently in heavy growth—standard blades will handle that better.
