Honda Genuine OEM HRX217 (HRX2173HYA) (HRX2173HZA) (HRX2173VKA) Walk-Behind Lawn Mowers Rotary Blade Set

What It Is

This is a genuine OEM rotary blade set designed specifically for Honda HRX217 walk-behind mowers, including the HRX2173HYA, HRX2173HZA, and HRX2173VKA models. It replaces the stock blades for standard mulching, bagging, or discharging tasks.

Fitment & Compatibility

• Deck size: Fits 21-inch cutting decks only. Measure your blade length—stock is about 21 inches from tip to tip.
• Model check: Confirmed for HRX2173HYA, HRX2173HZA, and HRX2173VKA. Not compatible with HRX217 other variants (e.g., HRX2174 or HRX2175) without verifying blade part number.
• OEM vs aftermarket: This is Honda genuine; aftermarket blades may have different hole patterns or thickness. Always match the center hole shape (keyed or round) and bolt hole spacing.
• What to measure: Blade length, width, center hole diameter, and offset (if any). Compare against your current blade’s part number stamped on the blade.
• Deck type: Works with Honda’s MicroCut twin-blade system—this set includes two blades and necessary hardware (bolts, washers).

Key Things to Know

• Quality: Honda OEM blades are heat-treated and precision-balanced for cleaner cuts and longer life than generic steel alternatives.
• Installation difficulty: Moderate. You’ll need a socket wrench and torque wrench (recommended 35–45 ft-lbs). Blade bolt is reverse-threaded on some models—check your manual.
• Common gotcha: These blades are directional; the “up” arrow must point toward the deck. Installing upside down causes poor cut and vibration.
• Tip: Replace hardware (bolts/washers) if worn or deformed—included in this set, so don’t reuse old bolts.

Should You Buy It

Buy this if you want guaranteed fit, consistent mulching performance, and maximum blade life for your HRX2173 mower. It’s the right choice for owners who prefer OEM reliability over cheaper aftermarket options that may require modifications or sacrifice cut quality.
