21 Inch Mower Blade Kit 72511-VE1-020 72531-VE2-020 Compatible with Honda HRB215 HRB216 HRB217 HRM215 HRR216 HRS216 HRT216 Push & Self Propelled Lawn Mowers

What It Is

This is a 21-inch replacement blade kit for Honda push and self-propelled mowers, designed to cut grass by spinning at high RPM. It fits models with a 21-inch cutting deck, including HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, and HRT216 series.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches (measure blade tip to tip). This kit includes OEM part numbers 72511-VE1-020 and 72531-VE2-020, which are direct replacements for Honda OEM blades. Check your mower’s model number (stamped on the deck or under the seat) against the listed series—HRB, HRM, HRR, HRS, HRT. It works for both push and self-propelled versions. Aftermarket compatibility is not guaranteed for non-Honda decks, so stick to the listed models.

Key Things to Know

• Blade type: These are standard straight blades (not mulching or high-lift), ideal for general cutting. Not for bagging heavy grass or mulching leaves.
• Installation difficulty: Easy—requires a socket wrench and blade removal tool (or a block of wood to lock the blade). Torque blade bolt to 30-40 ft-lbs.
• Common gotcha: The blade center hole is 7/8-inch, and the drive pin/dowel is offset—ensure alignment before tightening. Re-sharpen or replace after 25-50 hours of use.
• Durability: Priced under $30, these are mid-range; expect to replace annually with regular use.

Should You Buy It

Buy this kit if you own one of the listed Honda models and need a direct OEM-fit blade for standard mowing. It’s a solid value for the price, with easy installation and reliable performance for average lawns. Skip it if you need mulching or bagging blades—look for a dedicated set.
