72531-VH7-000 72511-VL0-S00 Mulching Blades for Honda HRR2169VKA HRR216 HRR2169VYA HRR216VKA HRR216k10VKAA HRR216k9VKAA HRN216 HRX217 21" Walk-Behind Mower (2pack)

What It Is

This is a 2-pack of OEM Honda mulching blades (part numbers 72531-VH7-000 and 72511-VL0-S00) designed for 21-inch Honda walk-behind mowers. They chop grass clippings finely and recirculate them into the lawn, eliminating bagging.

Fitment & Compatibility

• Deck size: 21-inch cutting deck only. Do not use on 20-inch or 22-inch decks.
• Models confirmed fit: HRR2169VKA, HRR2169VYA, HRR216VKA, HRR216k10VKAA, HRR216k9VKAA, HRN216, HRX217 (most variants). Also fits HRR216 series with 21" steel decks.
• Check before buying: Measure your existing blade length (must be exactly 21 inches). Verify your mower uses two blades (not one long blade or a single mulching blade). Confirm your model number on the engine cowling or under the rear flap—HRR216 models with aluminum decks may use a different blade.
• OEM vs aftermarket: These are genuine Honda, not aftermarket copies. Aftermarket blades often have different hole patterns or thicknesses—stick with OEM for guaranteed fit.

Key Things to Know

• Installation difficulty: Easy. Requires a socket wrench (usually 15mm or 5/8 inch) and a block of wood to lock the blade. Torque to 35-40 ft-lbs.
• Sharpness out of box: They come sharp but not razor-edged. Expect a break-in cut on the first mow.
• Common gotcha: These are mulching-only blades—they have a curved, high-lift design. Do not use for bagging or side discharge; they will clog and leave clumps.
• Durability: Good for one season of regular mowing on a typical lawn. Replace if nicked, bent, or after 25 hours of use.

Should You Buy It

Buy this if you own a compatible 21-inch Honda HRR216, HRN216, or HRX217 mower, want OEM reliability, and primarily mulch your grass. Avoid if you bag or side-discharge—you need standard or high-lift blades for those tasks.
