21'' Mower Blades Compatible Hond 72531-VH7-000 Blade & 72511-VL0-S00 21 inch Deck Compatible HRX217, HRX217K1, HRX217K2, HRX217K3, HRX217K4 Mower 21" Blade Set HRX217 HRR216, 2pck

What It Is

This is a 2-pack of 21-inch replacement blades designed for Honda HRX217 and HRR216 mowers. They match OEM part numbers 72531-VH7-000 and 72511-VL0-S00, making them a direct aftermarket alternative for standard mulching or bagging use on 21-inch deck Honda mowers.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 21 inches. Measure your blade length (tip to tip) – if it’s 21 inches, these will fit. If your deck is 20 or 22 inches, skip.
• Model list: Confirmed compatible with HRX217 (all variants: K1, K2, K3, K4, VKA, VLA, TDA, etc.) and HRR216 (K9, VKA, VLA, etc.). Not for HRX217HYA (hydrostatic) or older HR215 models.
• OEM cross-reference: Replacements for Honda 72531-VH7-000 and 72511-VL0-S00. Check your current blade part number stamped on the blade or in your manual. Aftermarket blades may have slightly different balance or steel thickness than OEM.

Key Things to Know

• Quality: At $31.99 for two, these are budget-oriented. Expect adequate sharpness and durability for residential use, but not the same edge retention or balance as OEM Honda blades. Inspect for burrs or uneven edges before installing.
• Installation: Standard 5/8-inch center hole, single bolt per blade. You’ll need a socket wrench and a block of wood to jam the blade. Torque to 40-50 ft-lbs. No special tools required.
• Common gotcha: These are not “Gator” or high-lift blades – they’re standard mulching/bagging profiles. If you need aggressive mulching or leaf shredding, consider a different blade type. Also, check that the blade’s curved shape matches your deck’s discharge opening – some aftermarket blades can be too wide or have a different airlift pattern.
• Balance: Always balance after installation. Use a simple blade balancer – an unbalanced blade will vibrate, damage the spindle, and cut unevenly.

Should You Buy It

Buy this if you have a 21-inch Honda HRX217 or HRR216, need a quick, affordable replacement for regular residential mowing, and don’t mind slightly shorter blade life compared to OEM. Skip if you want premium edge retention, need specialized blades (high-lift, mulching, or Gator), or have a different deck size or model. For the price, it’s a solid value for basic maintenance.
