08720-VR8-M00 HRN Blade Set

What It Is

The 08720-VR8-M00 HRN Blade Set is a replacement blade set designed for Honda HRN series walk-behind mowers. It includes two blades specifically engineered for Honda’s MicroCut twin-blade system, which lifts and cuts grass for a finer clip and better bagging performance.

Fitment & Compatibility

• Deck size: Fits Honda HRN mowers with 21-inch decks (e.g., HRN216VKA, HRN216VLA, HRN216TDA).
• OEM vs aftermarket: This is an OEM Honda part (part number 08720-VR8-M00). Aftermarket equivalents exist but may not match the exact blade geometry or balance.
• Measurements: Each blade is approximately 20.5 inches long, 2 inches wide, with a 1.0-inch center hole and a 0.5-inch offset. Verify your current blade’s length and hole size before ordering.
• Check before buying: Confirm your mower model number (on the deck or manual) and that you’re replacing both blades—this set includes two, not one.

Key Things to Know

• Quality: OEM Honda blades are made from heat-treated steel; they hold an edge well but will dull faster in sandy or rocky soil. Sharpen after 10-15 hours of use.
• Installation: Requires removing two bolts per blade. Use a torque wrench (25-30 ft-lbs recommended). The offset must face upward toward the deck—reverse installation will cause vibration and poor cut.
• Common gotchas: The set includes a thin washer for each blade; don’t skip it. Overtightening can strip the spindle threads. If your mower has a “Versamow” system, ensure the blade stop is not damaged before installing.
• Balance: After sharpening, check blade balance on a nail or balancer. An unbalanced blade will shake the mower and damage the spindle over time.

Should You Buy It

If you own a Honda HRN mower and want a reliable, factory-spec cut and bagging performance, this set is a no-brainer at $22.58. It’s especially worth it for homeowners who mow weekly and want consistent results without tweaking aftermarket blades. Skip it if you mow rough terrain that regularly dents blades—cheaper aftermarket sets may be more cost-effective for frequent replacement.
