Honda Genuine OEM HRX217 (HRX2172HMA) (HRX2172HXA) (HRX2172VKA) Walk-Behind Lawn Mowers Rotary Blade Set

What It Is

This is a genuine Honda factory replacement blade set designed specifically for the HRX217 walk-behind mowers, including models HRX2172HMA, HRX2172HXA, and HRX2172VKA. It includes the main cutting blade and the dedicated rear discharge blade (MicroCut twin-blade system) for mulching, bagging, or discharging.

Fitment & Compatibility

Before buying, confirm your mower model number (found on a label under the rear flap or on the engine shroud). This set fits only 21-inch deck HRX217 series mowers with the Versamow system. It will not fit older HRX models (e.g., HRX217HYA, HRX217K9) or any non-Honda mowers. The blade measures 21 inches long with a 1-inch center hole and five-point star drive pattern. Do not assume aftermarket “compatible” blades are identical—OEM ensures proper balance and discharge performance.

Key Things to Know

• Quality: Honda OEM blades are heat-treated and sharpened for optimal cut quality and longer edge retention compared to most aftermarket options.
• Installation: Requires basic tools (socket wrench, torque wrench). Torque the center bolt to 30–35 ft-lbs. Blade orientation matters—the curved side faces upward toward the deck.
• Gotchas: The rear discharge blade must be installed in the correct position (rear slot) or the mower won’t mulch properly. Avoid over-tightening, which can strip the adapter.
• Frequency: Replace when blades are nicked, rounded, or after 25–30 hours of mowing for best results.

Should You Buy It

If you own a compatible HRX217 model and want factory-grade performance, durability, and guaranteed fit, this is the right choice. It’s ideal for owners who prioritize cut quality and don’t want to gamble with aftermarket blades that may cause vibration or poor mulching.
