Replacement 72511-VE1-020 & 72531-VE2-020 21" Blade Kit Compatible with Hon da HRB215 HRB216 HRB217 HRM215 HRR216 HRS216 HRT216 Lawn Mower

What It Is

This is a two-blade 21-inch replacement kit (OEM equivalents 72511-VE1-020 and 72531-VE2-020) designed for select Honda walk-behind mowers. It’s a direct swap for worn original blades, restoring clean cuts on residential lawns.

Fitment & Compatibility

• Deck size: Only fits 21-inch Honda decks. Measure your blade length (from tip to tip) to confirm 21 inches—other sizes will not work.
• Model check: Compatible with HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, and HRT216 series. Cross-reference your mower’s model number (e.g., HRB216K9) on the blade part numbers 72511-VE1-020 and 72531-VE2-020.
• OEM vs aftermarket: This is a non-Honda brand replacement. It uses the same center hole and mounting pattern, but blade thickness and steel grade may differ slightly from OEM. Verify the blade’s center hole diameter (usually 1 inch) and that the blade’s lift matches your deck’s design.
• What to check: Remove one existing blade and compare shape, hole size, and thickness. If your deck uses a single long blade, this kit won’t fit—it’s a two-blade system.

Key Things to Know

• Quality: Aftermarket steel is generally adequate for regular mowing, but may dull faster than OEM Honda blades on tough or sandy grass.
• Installation: Simple bolt-on job. Requires a socket wrench (typically 13mm or 15mm). Use thread-locker on bolts and torque to 30-40 ft-lbs. Always disconnect spark plug first.
• Common gotcha: The two blades are not identical—one has a different lift or shape. Mark them left/right during removal to avoid mixing them up on reinstall.
• Balance: Aftermarket blades often need balancing. Use a blade balancer or a nail in the wall; add weight to the light side if needed to prevent vibration.

Should You Buy It

If you own one of the listed Honda models and want an affordable, functional replacement without paying OEM prices, this kit works well for routine mowing. It’s not ideal for heavy commercial use or rough terrain where blade durability matters most—but for a small residential lawn, it’s a solid value at $28.
