72531-VH7-000 & 72511-VL0-S00 Mulching Blades Kit Compatible with Honda HRR216 HRX217 21 Inch Mower, with Air Filter and Fuel Filter

What It Is

This is a three-piece kit that includes two mulching blades (OEM part numbers 72531-VH7-000 and 72511-VL0-S00) plus an air filter and fuel filter, designed for Honda HRR216 and HRX217 series 21-inch walk-behind mowers. The blades are meant for mulching—chopping clippings finely and recirculating them into the lawn—rather than bagging or side-discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch deck—this kit will not fit 20-inch or 22-inch Honda models. It’s compatible with HRR216 (all sub-models: VKA, VLA, VYA, etc.) and HRX217 (all sub-models: VKA, HYA, etc.). The blades are OEM-style replacements, not aftermarket universal fit. If your mower uses a different blade shape (e.g., the GCV160 engine with a different spindle), these won’t work. Check your owner’s manual or the existing blade’s part number to ensure 72531-VH7-000 and 72511-VL0-S00 match. The included air and fuel filters are generic replacements—verify your engine’s filter part numbers (typically 17210-Z0L-000 for air, 16910-Z0L-000 for fuel) to confirm compatibility.

Key Things to Know

• Installation difficulty: Moderate—you’ll need a socket wrench and a blade removal tool or block of wood to prevent spinning. Torque the blade bolts to 35–40 ft-lbs.
• Mulching only: These blades are not designed for bagging or side-discharge. Using them for those tasks will leave clumps and uneven cuts.
• Filters are a bonus, not premium: The air and fuel filters are basic aftermarket replacements. They work, but don’t expect OEM longevity or fit precision.
• Single review: The 5.0 rating is from one review—take it with a grain of salt. No widespread user feedback yet.

Should You Buy It

If you own a Honda HRR216 or HRX217 and want a one-stop kit for mulching blades plus routine filter replacements, this is a convenient, cost-effective option. It’s ideal for DIY homeowners who mulch regularly and prefer OEM-spec blades without the hassle of buying separately. Skip it if you need bagging blades, have a different deck size, or want premium OEM filters.
