Honda Genuine OEM Harmony II HRR216 (HRR2166PDA) (HRR2166VKA) (HRR2166VXA) Walk-Behind Lawn Mowers Rotary Blade Set

What It Is

This is a Genuine Honda OEM rotary blade set designed specifically for the Harmony II HRR216 walk-behind mowers. It’s the factory replacement blade for cutting grass on residential lawns, not for mulching or bagging heavy debris.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., HRR2166PDA, HRR2166VKA, HRR2166VXA) on the engine cowling or under the rear flap. This set fits only 21-inch deck Honda Harmony II HRR216 series mowers with the “Versamow” system—it will not fit older HRR215, HRR217, or non-Harmony models. Measure your current blade’s length (21 inches tip-to-tip) and center hole diameter (usually 1 inch). If you have an aftermarket blade, check that the offset and wing profile match; OEM blades have a specific curve for proper airflow. Do not use on decks larger or smaller than 21 inches.

Key Things to Know

• Quality: Honda OEM steel is heat-treated for durability and balanced out of the box. Aftermarket blades may be thinner or unbalanced, causing vibration.
• Installation Difficulty: Easy—requires a socket wrench (usually 14mm or 15mm) and a block of wood to lock the blade. Torque the bolt to 35-40 ft-lbs; overtightening can strip the adapter.
• Common Gotcha: This is a standard blade, not a mulch or high-lift blade. If you want better bagging, you need Honda’s high-lift blade (part 72511-VH2-000). For mulching, use the dedicated mulching blade (part 72511-VH2-010). Mixing blade types with the Versamow system reduces performance.
• Set Contains: Two blades (one for each spindle on dual-blade models) and a bolt/washer kit—check your mower uses two blades (HRR2166PDA does; some single-blade variants exist).

Should You Buy It

If you own a Honda Harmony II HRR216 with the Versamow system and want a reliable, factory-fit replacement for standard cutting, this is the right choice. It’s ideal for DIY homeowners who prioritize longevity and vibration-free operation over cheap aftermarket options. Skip it if you need a dedicated mulching or high-lift bagging blade—buy the specific Honda accessory instead.
