What It Is

This is a 2-pack of 21-inch replacement blades designed for select Honda walk-behind mowers. They’re meant for standard mulching and bagging on residential lawns, not commercial or heavy-duty use.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck and is one of these Honda models: HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, or HRT216. This kit replaces OEM part numbers 72511-VE1-020 and 72531-VE2-020 (and their -010 predecessors). Measure your existing blade’s center hole diameter (should be roughly 1 inch) and overall length (21 inches from tip to tip). These blades are not compatible with 20-inch or 22-inch decks, nor with Honda models outside the listed series. If your mower uses a different blade shape (e.g., “Gator” or high-lift), this standard flat blade won’t perform the same.

Key Things to Know

• Quality: Aftermarket blades are typically thinner and less durable than OEM Honda steel. They’ll cut fine but may dull faster, especially on rocky or sandy soil.
• Installation: Straightforward—remove the center bolt, swap blades, and torque to 30-40 ft-lbs. No special tools beyond a socket wrench. Always disconnect the spark plug first.
• Balance: These blades often come slightly unbalanced out of the pack. If you notice vibration after install, balance them with a simple blade balancer or file the heavy side.
• Common gotcha: The 2-pack includes one left-hand and one right-hand blade (marked L and R). Don’t mix them up—the wrong orientation will cause poor cut and vibration.

Should You Buy It

Buy this if you own a compatible Honda 21-inch mower, want a budget-friendly replacement for light-to-moderate residential use, and don’t mind slightly reduced longevity compared to OEM. Skip if you need commercial durability, have a different deck size, or prefer premium steel that holds an edge longer.
