What It Is

This is a set of three OEM Honda mulching blades designed for 21" Honda walk-behind mowers, specifically the HRR216, HRX217, and select HRN216 series. They replace part numbers 72511-VL0-S00, 72531-VH7-000, and 72511-VH7-000, and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Your mower must have a 21-inch cutting deck. These blades will not fit 20" or 22" decks.
• Model compatibility: Confirmed fit for Honda HRR216VKA, HRR2169VYA, HRR216K10VKAA, HRR216K9VKAA, HRN216, and HRX217 series (including VKA, VYA, VLA, TDA, TTA, PHA). Double-check your mower’s model number on the deck or under the seat.
• OEM vs aftermarket: These are genuine Honda blades, not aftermarket. They match OEM specs exactly—no need to adjust blade length or center hole size. The center hole is 1" with a 5-point star pattern. Blade length is 21.75" (end to end), and thickness is 0.125".
• What to measure: If your current blade is bent or worn, measure from the center hole to the tip (should be 10.875") and compare.

Key Things to Know

• Quality: Honda OEM blades are heat-treated and balanced from the factory. They last longer than most aftermarket mulching blades and resist chipping on rocks or roots.
• Installation: Easy for DIYers—just a 5/8" socket and a torque wrench (tighten to 35-40 ft-lbs). Use a blade removal tool or block the blade with wood to prevent spinning. Always lift the mower deck or tip it on its side (fuel cap up) for safety.
• Common gotcha: These are mulching blades, not bagging or side-discharge. If you switch between mulching and bagging, you’ll need a separate set of bagging blades. Also, mulching works best with dry grass—wet clippings clump and require more passes.
• Maintenance: Sharpen after 25 hours of use or when you see frayed grass tips. Replace if bent or cracked—never straighten a bent blade.

Should You Buy It

Buy these if you own a compatible Honda 21" mower and want OEM-quality mulching blades that fine-cut clippings for a clean, natural look. They’re a direct, no-mod fit for your deck, and the price is fair for genuine Honda durability. Skip if you need bagging or side-discharge blades, or if you’re on a tight budget—aftermarket mulching blades cost less but may not last as long.
