GANCO 72511-VH7-000 72531-VH7-000 72511-VL0-S00 Mulching Blades Set Replacement Part for Honda HRX217 HRX217K1 HRX21K2 Lawn Mower with 21" Deck (Pack of 2 Lawn Mower Blades)

What It Is

This is a set of two OEM-grade mulching blades designed for Honda HRX217 mowers with a 21-inch deck. They replace part numbers 72511-VH7-000, 72531-VH7-000, and 72511-VL0-S00, optimized for fine grass clipping mulching rather than bagging or side discharge.

Fitment & Compatibility

• Deck size: Must be exactly 21 inches. Measure your deck width before ordering.
• Models: Fits Honda HRX217, HRX217K1, HRX217K2, HRX21K2, and similar HRX series with the same deck. Not for HRX models with different deck sizes or older non-HRX models.
• OEM vs aftermarket: These are Honda-branded blades, not third-party. That means exact match, but higher price than generic options.
• Measurements: Each blade is roughly 21 inches long with a specific center hole and offset pattern. Check your existing blade for part number stamped on it to confirm compatibility.

Key Things to Know

• Mulching performance: Designed for fine cutting and recirculation; they won’t bag or side-discharge well. If you need versatility, consider a 3-in-1 blade set.
• Installation: Requires a socket wrench and torque to 45-55 ft-lbs. Use a blade removal tool or block the blade to prevent spinning. Easy for DIY with basic tools.
• Balance: Each blade is pre-balanced, but always check after sharpening. An unbalanced blade causes vibration and deck damage.
• Gotcha: These are sold as a pair, but some HRX models use a single blade. Verify your mower uses two before buying.

Should You Buy It

Buy these if you own a Honda HRX217 with a 21-inch deck, want genuine OEM fit and mulching performance, and don’t need bagging or discharge options. They’re reliable, easy to install, and perfect for maintaining a clean, mulched lawn. Skip them if you need multi-purpose blades or have a different deck size.
