MaxPower's 561657B 2 Blade Set for 21" Honda Mowers, Replaces OEM Numbers 72511-VK6-000, 72531-VK6-010

What It Is

MaxPower’s 561657B is a set of two replacement blades designed for 21-inch Honda walk-behind mowers. These are standard lift blades for medium-duty residential cutting, not mulching or high-lift blades.

Fitment & Compatibility

Deck size: Must be exactly 21 inches. Measure your deck width—blades are 20.5 inches tip-to-tip.
Honda models: Fits most HRX217, HRR216, HRS216, and HRS215 series from the 2000s onward. Check your model number on the deck sticker.
OEM replacement: Replaces Honda parts 72511-VK6-000 and 72531-VK6-010. If your mower originally used either of these numbers, these fit.
Measurements: Center hole is 1 inch diameter with a 5-point star pattern. Blade thickness is 0.150 inches.
Aftermarket note: Not compatible with Honda’s “Versamow” system or mulching-only decks. If your mower has a separate mulching blade, this set is for the standard cutting blade position.

Key Things to Know

• Quality: Heavy-duty steel with hardened edge. Good balance between durability and sharpness retention. Not as premium as OEM Honda but fine for regular mowing.
• Installation: Straightforward—use a torque wrench to 30-35 ft-lbs. The star pattern centers the blade automatically; no balancing required if you buy as a set.
• Common gotcha: These are NOT for Honda’s 21-inch self-propelled models with the “MicroCut” twin-blade system (e.g., HRX217VKA). Those use different blade shapes.
• Performance: Good lift for bagging and side discharge. Slightly less aggressive than OEM for thick or wet grass.

Should You Buy It

Buy these if you need a reliable, budget-friendly replacement for a standard 21-inch Honda mower and don’t need mulching capability. Skip them if you have a Versamow deck or want OEM-grade longevity—stick with genuine Honda blades for heavy use.
