Honda 72511-VG3-000 Lawn Mower Blade Genuine Original Equipment Manufacturer (OEM) Part

What It Is

The Honda 72511-VG3-000 is a genuine OEM mulching blade designed for select Honda HRX and HRS walk-behind mowers. It’s engineered for fine grass clipping mulching, not bagging or side-discharge.

Fitment & Compatibility

• Deck size: Fits 21-inch Honda mower decks only (not 20″ or 22″ models).
• Model check: Compatible with HRX217 (all sub-models like VKA, VLA, HMA) and HRS216 (e.g., VKAA, VLA). Also fits HRX217HYA, HRX217HZA, HRX217VKA, and HRX217VLA.
• OEM vs aftermarket: This is genuine Honda—identical to the blade that came with your mower. Aftermarket copies (e.g., Oregon, Stens) may have slightly different hole shapes or balance; if you want guaranteed fit, stick with OEM.
• Measurements: Blade length is 21 inches, center hole diameter is 1 inch, and it has two oblong mounting holes spaced 4 inches apart. Measure your old blade to confirm.
• Not for: Honda HRR, HRS215, or any non-HRX/HRS deck. Also incompatible with blade stop systems on some older models—check your mower’s blade bolt setup.

Key Things to Know

• Mulching only: This blade has a high-lift design with a curved wing on the back to recirculate clippings. It won’t bag well or discharge properly—use it only for mulching.
• Installation difficulty: Easy (15-30 minutes) with a socket wrench and blade removal tool. Torque the blade bolt to 30-40 ft-lbs. Use thread locker if your mower vibrates heavily.
• Common gotcha: The blade is directional—the angled wings must point up toward the deck when installed. Installing upside down will cause poor cut and vibration.
• Balance check: Even new OEM blades can be slightly off-balance. Test by balancing on a blade balancer; if it tips, file the heavy side lightly until level.

Should You Buy It

Buy this if you own a Honda HRX or HRS mower and want a perfect-fit, long-lasting mulching blade that delivers fine clippings without clogging. It’s the right choice for fine lawns where bagging isn’t needed. If you need a bagging or discharge blade, or if your mower isn’t an HRX/HRS model, look elsewhere.
