Lawn Mower Blades for Honda HRR216 HRR216K9 VKA VYA, HRX217, High Lift Mulching Blades for Walk Behind Mowers, 21" Twin Blade Set Replaces OEM no. 72531-VH7-000 & 72511-VH7-000 (Set of 2)

What It Is

This is a high-lift mulching blade set for select Honda walk-behind mowers. It uses a twin-blade design to create a vacuum that lifts grass for finer clipping and better bagging, ideal for mulching or side-discharge use.

Fitment & Compatibility

Before buying, confirm your mower model matches: this set fits Honda HRR216 (models VKA, VYA, K9, TDA, TLA, VLA), HRR216K9, and HRX217 (HZA, HYA, K4, TDA, VLA, VYA). The blades are 21 inches long, sold as a pair, and replace OEM part numbers 72531-VH7-000 (right) and 72511-VH7-000 (left). Check your deck’s spindle bolt pattern—these use a standard 1-inch center hole with a 5-point star drive. Measure your existing blade length and hole size before ordering; not compatible with 20-inch or 22-inch decks.

Key Things to Know

• Mulching vs. bagging: High-lift blades improve bagging and mulching, but increase engine load and may reduce runtime on battery models.
• Installation: Requires a torque wrench (set to 35-40 ft-lbs) and a blade removal tool to lock the spindle. Sharpening is possible, but replacement every 25 hours of use is recommended.
• Material: Made from heat-treated steel; less durable than hardened alloy blades but still solid for residential use.
• Common gotcha: The left and right blades are not interchangeable—mark them during removal to avoid mixing up.

Should You Buy It

If you have a compatible Honda HRR216 or HRX217 and want OEM-level performance at a lower price, this set is a reliable choice. It’s best for homeowners who mow weekly and need consistent mulching or bagging results, not for heavy-duty commercial use where longer blade life is critical.
