2511-VR8-M00 Bottom Blade and 72531-VR8-M00 Upper Blade Set Kit for Hon da HRB215 HRB216 HRB217 HRM215 HRR216 HRS216 HRT216 Push and Propelled Lawn Mower

What It Is

This is a two-blade set (bottom blade 2511-VR8-M00 and upper blade 72531-VR8-M00) designed for Honda HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, and HRT216 walk-behind mowers. It replaces the OEM Honda blades for both standard push and self-propelled models with a 21-inch cutting deck.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 21 inches—this set will not fit 20-inch or 22-inch decks. Verify your Honda model number (e.g., HRB215SDA) and check that your mower uses a two-blade system (some Honda models use a single blade). The set is aftermarket, not OEM Honda, so it may not match the exact balance or thickness of factory blades. Measure the existing blade length and mounting hole pattern (usually a 1-inch center hole with a 5-point star or keyed slot) to ensure compatibility.

Key Things to Know

• Quality: These are budget aftermarket blades; they may be thinner or less durable than OEM Honda blades, especially on heavy grass or rocks.
• Installation: Straightforward with basic tools (socket wrench, torque wrench recommended). Torque the center bolt to 30-40 ft-lbs. No special adapters needed.
• Balance: Always check blade balance after installation—unbalanced blades cause vibration and deck damage. Use a blade balancer or nail-in-wall method.
• Gotcha: The bottom blade (2511-VR8-M00) is the “mulching” blade; the upper blade (72531-VR8-M00) is the “lift” blade. Installing them reversed will ruin cut quality and may damage the deck.

Should You Buy It

This kit is a solid budget option if you need a quick, functional replacement for a 21-inch Honda mower and don’t mind slightly less longevity than OEM blades. It’s best for homeowners with light-to-medium duty mowing on small lawns. Avoid it if you mow professionally, need premium cut quality, or want maximum durability—spend the extra on genuine Honda blades.
