Mulching Blades for Honda HRN216 Series Lawn Mowers, High Lift Mulching Blades for Walk Behind Mowers, 21" Twin Blade Set Replaces OEM no. 72511-VR8-M00, 72531-VR8-M00 (Set of 2)

What It Is

This is a set of two high-lift mulching blades designed for Honda HRN216 series walk-behind mowers. They replace OEM part numbers 72511-VR8-M00 and 72531-VR8-M00, and are intended for fine mulching (chopping clippings into small bits) rather than bagging or side-discharge.

Fitment & Compatibility

• Deck size: Only fits 21-inch cutting decks.
• Model check: Confirmed for Honda HRN216VKA, HRN216VLA, HRN216VMA, and HRN216VYA. Not for older HRX or HRC series.
• OEM vs aftermarket: These are genuine Honda blades—same as factory. No fitment guesswork.
• Measurements: Each blade is ~21" long, 1.25" wide, with a 1" center hole and a 0.5" offset. Center hole must match your spindle; if your mower uses a star-shaped or keyed hole, these won’t work.
• Check before buying: Remove one blade and verify hole shape and overall length. Also confirm your mower takes a twin-blade set (two blades mounted on two separate spindles).

Key Things to Know

• High-lift design creates strong airflow to suck grass upward for a cleaner cut, but increases engine load slightly—expect a minor drop in run time.
• Installation difficulty: Easy—requires a socket wrench and blade removal tool (or block of wood to jam the blade). Torque blades to 35-40 ft-lbs.
• Common gotcha: These are not universal. Do not use on single-blade decks or models with a different mounting pattern. Also, high-lift blades can throw debris; always wear eye protection.
• Sharpness: Come sharp from factory, but pre-sharpening isn’t needed. Resharpen after ~25 hours of use.

Should You Buy It

Buy this if you own a Honda HRN216 and want OEM-quality mulching performance with less clumping and finer clippings. It’s a direct drop-in replacement that works well for frequent mowing on thick or damp grass. Skip it if you primarily bag or side-discharge—standard lift blades are better for that.
