72511-VE1-020 72531-VE2-020 21" Micro Cut Twin Blade Kit for HRR216 HRX217 HRR216K9VKAA HRR216K2 PDAA SDAA

What It Is

This is a twin-blade kit (two blades) designed for Honda HRR216 and HRX217 series mowers with 21-inch decks. The Micro Cut design uses a smaller, high-lift upper blade and a larger, flat lower blade to create a vacuum that lifts grass for a finer, mulched cut—ideal for frequent mowing and leaf mulching.

Fitment & Compatibility

Check your mower model and deck size. This kit fits 21-inch Honda decks only. Compatible models include HRR216K9VKAA, HRR216K2 PDAA, SDAA, and all HRR216/HRX217 variants that accept OEM part numbers 72511-VE1-020 (upper blade) and 72531-VE2-020 (lower blade). Measure your existing blade length—upper blade is ~18 inches, lower is ~21 inches. Verify the center hole diameter (usually 1 inch) and that your spindle can accept two blades stacked. Not compatible with older HRR216 models (e.g., HRR216K1) that use single-blade systems. Cross-check with your owner’s manual or Honda’s parts diagram.

Key Things to Know

• Installation: Requires removing the single blade, then stacking the upper blade (with the curved lift facing up) and lower blade (flat side down) on the spindle. Torque to 30-40 ft-lbs. Use threadlocker on bolts.
• Cut quality: Produces finer clippings than a standard blade, but may struggle with tall, wet grass—mulch in passes for best results.
• Durability: OEM-equivalent steel, but aftermarket blades can dull faster than Honda genuine parts. Sharpen or replace every 2-3 seasons.
• Gotcha: The upper blade’s high lift can cause vibration if not balanced. Check blade balance after installation.

Should You Buy It

Buy this if you own a compatible Honda HRR216 or HRX217 and want a finer, mulched cut for regular mowing—especially for leaf mulching. Skip it if you mow infrequently or in tall, wet grass; a standard single blade will be more forgiving. For the price, it’s a solid upgrade over a worn OEM blade.
