72511-VE1-020 & 72531-VE2-020 Lawn Mower Blade Set, Compatible with Hon da 21" HRB215 HRB216 HRB217 HRM215 HRR216 HRS216 HRT216, Replace 72511-VE1-010 72531-VE2-010 2-Pack

What It Is

This is a 2-pack of replacement blades for Honda 21-inch walk-behind mowers. Designed for mulching, bagging, and side-discharge cutting on residential lawns, it directly replaces OEM part numbers 72511-VE1-010 and 72531-VE2-010.

Fitment & Compatibility

• Deck size: Only fits 21-inch cutting decks. Measure your blade length (end to end) before buying—must be exactly 21 inches.
• Compatible Honda models: HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, HRT216. Check your mower’s model plate (usually under the rear flap or on the deck) to confirm.
• OEM vs aftermarket: This is a non-OEM set. It matches the original dimensions and mounting hole pattern (center hole size, 5-point star shape), but verify your blade adapter type—some Honda decks use a different drive pin arrangement.
• What to measure: Blade length (21"), center hole diameter (typically 1-1/8"), and thickness (approx. 0.110"). If your current blade has a different center hole or offset, this set won’t fit.

Key Things to Know

• Quality: Made from hardened steel with a painted finish. Users report good balance and edge retention for standard residential use, but not as durable as OEM for heavy or rocky terrain.
• Installation difficulty: Easy if you have a socket wrench and blade removal tool. Torque bolts to 40-50 ft-lbs. Use a thread locker if bolts loosen over time.
• Common gotcha: The star-shaped center hole may not align with all Honda blade adapters. If your mower uses a “dogbone” or pin-style adapter, this set is incompatible. Also, these blades are not reversible—install with the cutting edge facing the direction of rotation.
• Sharpness: Out of the box, they are sharp but may need a quick touch-up for best performance. Dull blades tear grass, so sharpen after ~10 hours of use.

Should You Buy It

Buy this set if you have a compatible 21-inch Honda mower, want a budget-friendly replacement for normal home lawn care, and don’t need OEM durability for frequent commercial use. Avoid it if your mower uses a non-standard blade adapter or you cut heavy, debris-filled grass regularly.
