Honda 72511-VK6-000 & 72531-VK6-010 Mower Blade Set

What It Is

This is an OEM Honda two-blade set (part numbers 72511-VK6-000 for the left blade and 72531-VK6-010 for the right blade) designed specifically for Honda HRX217 series mowers. These blades are the factory-recommended replacement for the “MicroCut” twin-blade system that provides finer clipping and better bagging performance.

Fitment & Compatibility

Before buying, verify your mower model. This set fits Honda HRX217 models with the Versamow system, including HRX217HYA, HRX217HZA, HRX217K4, HRX217TDA, and HRX217VKA. Do not assume fitment for other Honda models – the twin-blade system is unique to the HRX217 series. Measure your existing blades: each blade is approximately 21 inches long, with a 6-point star center hole and a 90mm blade bolt pattern. If your deck is 21 inches and uses two separate blades (not a single bar), you’re likely compatible. Always cross-reference your mower’s serial number with Honda’s parts diagram – mismatched blades can cause excessive vibration or poor cut quality.

Key Things to Buy

• OEM vs. aftermarket: These are genuine Honda blades, so you get exact fit, balanced weight, and the same heat treatment as factory originals. Aftermarket “universal” sets often lack the precise star pattern or balance, leading to vibration and uneven cuts.
• Installation difficulty: Moderate. You’ll need a socket wrench (usually 14mm or 15mm) and a block of wood to jam the blade. Torque bolts to 30-35 ft-lbs – overtightening can strip the blade adapter. Mark which blade goes left vs. right before removal.
• Common gotchas: The blades are not interchangeable left-to-right – installing them reversed will ruin cut quality and may damage the deck. Also, these are not for mulching or side-discharge only; they work best with the HRX217 bagging system. If you use the Versamow lever for mulching, expect slightly less lift than a dedicated mulching blade.
• Sharpness: They come sharp but not razor-edged. For best results, sharpen after 10-15 hours of use or if you notice tearing instead of cutting grass.

Should You Buy It

If you own a Honda HRX217 and want the same cut quality and bagging performance as when the mower was new, this set is the right choice. It’s pricier than aftermarket options, but the precise fit and OEM reliability eliminate guesswork. Skip it if you have a different Honda model (e.g., HRR or HRS series) or if you’re looking for a heavy-duty mulching blade – in those cases, a single-blade aftermarket option will serve you better.
