72531-VE2-020 & 72511-VE1-020 Mulching Mower Blade Kit Compatible with 21" Deck Hon-da HRB215 HRM215 HRB216 HRB217 HRR216 HRS216 HRT216 HRZ216 Lawn Mower，2 Pack

What It Is

This is a two-pack of mulching blades (part numbers 72531-VE2-020 and 72511-VE1-020) designed for 21-inch deck Honda mowers in the HRB, HRM, HRR, HRS, HRT, and HRZ series. They chop clippings finely for nutrient recycling, eliminating bagging on most residential lawns.

Fitment & Compatibility

• Deck size: Must be exactly 21 inches. Measure your mower’s deck width if unsure.
• Model check: Confirmed for HRB215, HRM215, HRB216, HRB217, HRR216, HRS216, HRT216, HRZ216. Not compatible with older HR214 or newer HRX models.
• OEM vs aftermarket: These are aftermarket replacements for Honda OEM blades. Verify your existing blade part number matches 72531-VE2-020 or 72511-VE1-020.
• Measurements: Each blade is about 21 inches long, with a 2.25-inch center hole and offset mounting tabs. Compare to your old blade’s length, hole diameter, and tab shape before installation.

Key Things to Know

• Quality: Made from hardened steel, but edges may dull faster than OEM Honda blades on heavy or rocky terrain. Check sharpness after 10-15 hours of use.
• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool (or wedge a block of wood against the blade to prevent spinning). Always disconnect the spark plug first.
• Common gotcha: These blades are not universal—they only fit the specific Honda models listed. Double-check your mower’s model number on the deck sticker before purchasing.
• Balance: After installing, spin the blade by hand to check balance. Unbalanced blades cause vibration and damage the spindle. If wobbling, replace.

Should You Buy It

If you own one of the listed Honda 21-inch mowers and want an affordable mulching upgrade without paying OEM prices, this two-pack delivers solid value for the money. However, if you mow very dense or damp grass regularly, invest in OEM blades for longer edge retention. For most homeowners, this kit is a practical, budget-friendly choice.
