72511-VH7-000 & 72531-VH7-000 Lawn Mower Blade Kit - 21" Dual Mulching Blades for Honda HRX217 HRX217K1 HRX217K2 HRX217K3 HRX217K4 HRX217HXA HRX217VKA - Replace Upper & Lower Blades

What It Is

This is a genuine Honda OEM dual-blade kit (upper blade 72511-VH7-000, lower blade 72531-VH7-000) designed for the HRX217 series’ Versamow system. The two blades work together to mulch or bag—switching between cutting and lifting action depending on deck position.

Fitment & Compatibility

Only fits Honda HRX217 models with the Versamow deck: HRX217K1, K2, K3, K4, HXA, VKA, and earlier HRX217 variants. Does not fit HRX216, HRR216, or any non-Versamow deck.

• Deck size must be 21 inches.
• Measure your existing upper blade length (approx. 21”) and lower blade (approx. 16.5”) to confirm.
• Check your model number on the deck’s sticker or under the seat—this kit replaces only OEM Honda parts, not aftermarket “universal” blades.
• If you’re swapping from a single-blade setup, you need the entire Versamow system, not just blades.

Key Things to Know

• Installation is moderate – you must align both blades and the drive plate correctly; the lower blade has a specific offset. Tighten bolts to 35-40 ft-lbs.
• Mulching quality is excellent – the dual-blade design creates a fine cut, but only if the deck is clean and blades are sharp. Dull blades will tear grass.
• Beware of counterfeit – genuine Honda blades have a distinct blue coating and stamped part numbers. Cheap knockoffs may not balance correctly.
• Use only OEM hardware – the included bolts and washers are torque-to-yield; reuse them at your own risk. Replace every season or after hitting a large obstacle.

Should You Buy It

If you own an HRX217 with Versamow and want factory-grade mulching performance without guesswork, this kit is the right choice. It’s pricier than aftermarket sets, but the fit, balance, and cut quality are proven. Skip it if you have a different model or prefer single-blade bagging—you’ll need a different setup.
