Honda HRX Blade Kit, (1) 72511-VH7-000 Blade & (1) 72531-VH7-000 Blade

What It Is

This is an OEM Honda two-blade kit for the HRX mower series, designed to replace the factory-installed dual blades that work together to create a finer, more consistent cut and improve mulching performance.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch deck and is a Honda HRX model (not HRR, HRS, or other series). This kit fits all HRX models with the MicroCut twin-blade system, including HRX217, HRX217HYA, HRX217K4, HRX217VKA, and similar variants. Measure your existing blade length: each blade is approximately 21 inches long from tip to tip. Check the center hole diameter (usually 1-inch) and ensure the blade offset matches your deck. Always verify your model number against Honda’s official parts diagram—some early HRX models may use different blade part numbers.

Key Things to Buy

• Quality & Durability: Honda OEM blades are heat-treated and balanced from the factory. They last longer than most aftermarket options and hold an edge better, but they cost more.
• Installation Difficulty: Easy for a DIYer with basic tools. You’ll need a socket wrench and a torque wrench (recommended torque: 40-50 ft-lbs). Use a blade removal tool or block the blade to prevent spinning.
• Common Gotchas: These blades are directional—install them with the cutting edge facing the direction of rotation. Mixing up left and right blades (the two part numbers are not interchangeable) will cause poor cutting and vibration. Always replace both blades as a set to maintain balance.
• Sharpening vs. Replacement: Resharpening OEM blades is possible, but the hardened steel can be tough to sharpen well. Most users replace them once a season or after hitting a large rock.

Should You Buy It

Buy this kit if you own a Honda HRX mower and want guaranteed fit, reliable performance, and minimal hassle. It’s the right choice for anyone who prioritizes cut quality and mower longevity over saving a few dollars on generic blades. Avoid it if you have a non-HRX model or are looking for budget aftermarket options.
