Honda Genuine 72511-VG4-K00 & 72531-VE2-020 Mower Blade Set OEM

What It Is

This is a genuine Honda OEM 2-blade set (part numbers 72511-VG4-K00 and 72531-VE2-020) designed for select Honda HRX and HRS mower models. It replaces the factory blades on 21-inch deck Honda walk-behind mowers, ensuring a precise fit and optimal cutting performance.

Fitment & Compatibility

Before buying, confirm your mower deck size is 21 inches and your model is from the HRX217 (e.g., HRX217HYA, HRX217VKA, HRX217K5) or HRS216 series. This blade set is OEM-only; aftermarket “universal” blades may not match the blade length (21 inches), center hole diameter (usually 1 inch), or offset. Check your current blade’s part number or use Honda’s online lookup with your mower’s serial number. Not compatible with HRR, HRS215, or older HRX models with different blade part numbers.

Key Things to Know

• Quality & Sharpness: Honda factory blades come pre-sharpened and balanced, with a hardened steel edge that holds up longer than most aftermarket options. Expect a clean, mulching or bagging cut depending on blade design (the set includes a standard blade and a mulching blade).
• Installation: Moderate difficulty. Requires a socket wrench (usually 15mm or 5/8-inch) and a blade removal tool or block of wood to prevent rotation. Torque bolts to 35-45 ft-lbs (check your manual). Reinstall with the “up” arrows facing the deck.
• Common Gotchas: The mulching blade (72531-VE2-020) is often shorter and has a curved design—do not install it on the wrong side. Also, these blades are not for use with Honda’s “MicroCut” system on some HRX models (requires a different part).
• Set vs. Single: This is a two-blade set; if you only need one, check your deck type. Most HRX 21-inch decks use two blades.

Should You Buy It

Yes, if you own a compatible Honda HRX or HRS 21-inch mower and want a guaranteed fit, long-lasting edge, and OEM reliability. It’s ideal for homeowners who value a precise cut and don’t want to risk cheap aftermarket blades that may vibrate or dull quickly. Skip it if you have a different deck size or model—cross-check your serial number first.
