72531-VH7-000 72511-VL0-S00 Mulching Blades Filter Kit for Honda HRX217/HRR216 21" Microcut Twin Blade Kit Replace 17211-Z8B-901,Spark Plug,Bolts Fuel Filter,and Spacer

What It Is

This is a kit that bundles mulching blades, a fuel filter, a spark plug, bolts, and a spacer for Honda HRX217 and HRR216 21-inch walk-behind mowers. It’s designed to replace the OEM MicroCut twin blade system (part 17211-Z8B-901) and includes the necessary tune-up items for a single service.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch steel deck (not a composite deck). The kit fits HRX217 (all variants like VKA, HMA, etc.) and HRR216 (VKA, VLA, etc.) models. Check your existing blade part number—if it’s 17211-Z8B-901 (the MicroCut twin blade set), this is a direct replacement. The included spark plug fits most Honda GCV engines (e.g., GCV190, GCV200). The fuel filter is a generic replacement for Honda’s in-line filter on these models. Do not use on HRX models with the “Versamow” system that uses a single blade—this is strictly for the twin-blade MicroCut setup.

Key Things to Know

• Quality: Blades are OEM Honda, but the filter and plug are aftermarket. Some users report the fuel filter’s fit is slightly looser than OEM; consider using a zip tie if it doesn’t snug tight.
• Installation: Easy for the blades—just remove the center bolt, swap blades, and torque to 35-45 ft-lbs. The spacer must be placed between the two blades (thin metal disc). The spark plug and fuel filter are straightforward but require a socket and pliers.
• Common gotcha: The kit includes two blades and one spacer. If your mower uses a different blade orientation (e.g., left-hand vs. right-hand thread), verify the bolt pattern—this kit uses standard 5/16-24 bolts.
• Performance: Mulching quality is good for grass up to 4 inches tall. For tall or wet grass, you may need to slow your pace or double-cut.

Should You Buy It

Buy this if you own a Honda HRX217 or HRR216 with the MicroCut twin blade system and want a single kit for blades, air filter, and spark plug. It’s a decent value for the convenience, but if you prefer premium fuel filters or plugs, you might source those separately. For most owners, it’s a solid all-in-one maintenance solution.
