Rotary Item 2160, Mulching Blade 20-7/8-in X .845-in, Replaces Honda 72511-960-004, 72511-VA2-690

What It Is

The Rotary 2160 is a 20-7/8-inch mulching blade designed for Honda lawn mowers. It replaces OEM part numbers 72511-960-004 and 72511-VA2-690, and is ideal for homeowners who want fine grass clipping recycling rather than side discharge or bagging.

Fitment & Compatibility

Before buying, confirm three things:

1. Blade length: Must be exactly 20-7/8 inches from tip to tip. Measure your current blade or check your mower deck size (typically 21-inch or 22-inch decks use this length).
2. Center hole & drive: The blade has a 0.845-inch center hole and a 5-point star drive pattern – verify your mower’s spindle matches this. Common on Honda HRX217, HRC216, and HRR216 series.
3. Model check: This replaces Honda OEM 72511-960-004 (used on many Honda mowers from 2000–2015) and 72511-VA2-690 (found on newer HRX217 models). Cross-reference your mower’s model number with Honda’s parts diagrams if unsure.

Avoid assuming “universal fit” – Honda blades have a specific drive pattern that standard blades may not match.

Key Things to Know

• Mulching performance: The blade’s high-lift design and curved wings chop clippings finer than standard blades, but only works well if you mow regularly and keep the blade sharp.
• Installation: Simple – remove the old blade (use a socket wrench), install the new one with the wings pointing upward toward the deck. Torque the bolt to 35–45 ft-lbs. No special tools needed.
• Balance check: After install, spin the blade by hand to ensure it’s balanced. An unbalanced blade will vibrate, stress the spindle, and leave an uneven cut.
• Common gotcha: The blade may not fit mowers with a smaller center hole (e.g., 0.750-inch). Measure before buying if your mower is older than 2000.

Should You Buy It

Buy this if you own a compatible Honda mower (especially HRX217 or HRR216 series), want superior mulching without upgrading to a dedicated mulching system, and you mow weekly. It’s a reliable OEM-replacement blade at a fair price, with solid user reviews. Skip it if you need a standard lift blade for bagging or if your mower uses a different drive pattern.
