72531-VH7-000 & 72511-VH7-000 Mower Blades Kit, HRX Mulching Blades Set for 21" Deck, Compatible with Hon da HRX217 HRX217K1 HRX217K2 HRX217K3 HRX217K4 HRX537, 2 Pack

What It Is

This is a 2-pack of mulching blades (part numbers 72531-VH7-000 and 72511-VH7-000) designed for 21-inch Honda HRX mower decks. They replace OEM blades on HRX217 and HRX537 series mowers, cutting grass into fine clippings for natural lawn feeding.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 21 inches (measure from blade tip to tip). These blades fit Honda HRX217 models: HRX217K1, K2, K3, K4, and HRX537 series. They are direct replacements for OEM Honda blades—no modifications or adapters needed. Check your current blade’s part number: if it’s 72531-VH7-000 or 72511-VH7-000, these are identical. Not compatible with other brands (e.g., Toro, Craftsman) or non-HRX Honda models.

Key Things to Know

• Quality: Aftermarket blades; some users report slightly thinner steel than OEM, but durability is adequate for residential use.
• Installation: Easy—remove the center bolt, swap blades, torque to 40-50 ft-lbs. Use a blade removal tool or block wood to prevent spinning.
• Gotcha: These are mulching blades only (not high-lift for bagging). If you bag often, consider a dedicated bagging blade set.
• Balance: Check blade balance after mounting; an unbalanced blade vibrates and can damage the spindle.

Should You Buy It

Buy this kit if you own a Honda HRX217 or HRX537 with a 21-inch deck and want an affordable mulching blade set for fine clippings. It’s a solid value for homeowners who mow weekly and prefer mulching over bagging. Skip it if you need OEM-grade steel for heavy-duty commercial use or require high-lift blades.
