72511-VL0-S00 & 72531-VH7-000 Mower Blade Set，Lawn Mower Mulching Blades 21 in. Compatiable with Honda Push and Propelled Mower

What It Is

This is a set of two 21-inch mulching blades designed for Honda push and self-propelled lawn mowers. They replace OEM part numbers 72511-VL0-S00 and 72531-VH7-000, and are intended for fine grass clipping recycling rather than bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches wide. These blades fit most Honda HRX217, HRR216, and HRS216 series mowers, but verify your model number—especially the suffix—as some older or non-Honda decks may require different blade shapes. Measure the blade length, center hole diameter (typically 1 inch), and the distance between the two outer mounting holes (around 3 inches). These are OEM Honda blades, not universal or aftermarket, so fitment is precise but limited to compatible Honda decks.

Key Things to Know

• Quality: OEM Honda steel blades, pre-sharpened and balanced. Expect consistent performance and durability similar to original equipment.
• Installation: Easy if you’ve done it before. Use a socket wrench to remove the blade bolt, note the orientation (sharp edge forward), and torque to 35-40 ft-lbs. No special tools needed.
• Common gotcha: These are mulching blades only—they won’t work well for bagging or side discharge. If you need a convertible blade, look for a 3-in-1 design.
• Maintenance: Sharpen every 10-15 hours of use or after hitting rocks/stumps. Replace if bent or chipped.

Should You Buy It

If you own a compatible 21-inch Honda mower and primarily mulch grass, this set is a direct, reliable replacement. It’s not for universal fit or mixed-use cutting, but for Honda owners who want OEM quality without hunting for aftermarket alternatives, it’s a solid, straightforward buy.
