72511-VE1-020 (Lower) Honda Genuine Lawn Mower Blade for Honda Mowers HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, HRT216, HRZ216

What It Is

This is a Honda Genuine lower blade (OEM part 72511-VE1-020) designed for Honda walk-behind mowers with a 21-inch cutting deck. It’s the lower blade in a twin-blade “MulchCommand” or “MicroCut” system, used for mulching, bagging, or discharging grass.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This blade fits Honda HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, HRT216, and HRZ216 series—all with 21-inch decks. Measure your existing blade length: this one is 20.75 inches long, 2.25 inches wide, with a 1-inch center hole and a 0.25-inch offset. It works only as the lower blade in a twin-blade setup—do not use it alone. Check your owner’s manual or existing part number to ensure you need the lower, not the upper blade (72511-VE1-010).

Key Things to Know

• OEM quality: Made by Honda to factory specs—sharper out of the box and lasts longer than most aftermarket blades. Expect consistent balance.
• Installation difficulty: Easy with a socket wrench and blade removal tool. Torque the center bolt to 35-40 ft-lbs. Always replace both blades as a set for even cutting.
• Common gotcha: This is the lower blade only. If you accidentally buy two of these, your mower won’t cut properly—you need the upper blade for the top position.
• Blade orientation: The curved side faces up toward the deck. Installing it upside down will cause poor cutting and vibration.

Should You Buy It

Buy this if you own a compatible Honda mower and want a direct OEM replacement that guarantees fit, balance, and cutting performance. It’s ideal for users who prioritize reliability over saving a few dollars on generic blades. If you need a budget option, aftermarket blades exist, but expect shorter life and possible imbalance.
