BGD 08720-VR8-M00 21" Mower Blades for Honda HRB215 HRB216 HRB217 | Replaces 3 Part Numbers, Fits Honda HRB Mowers, Upper + Bottom Blades, Hardened Steel, Precision Balanced, Bolt-On Install

What It Is

This is a matched set of two hardened steel blades (upper and lower) for 21-inch Honda HRB walk-behind mowers. Designed for the Honda HRB215, HRB216, and HRB217 series, it replaces three OEM part numbers and delivers a bolt-on upgrade for mowing thick or wet grass on residential and commercial properties.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches and that your model is one of the following: HRB215, HRB216, or HRB217 (check the model tag under the seat or on the deck). This set replaces OEM part numbers 08720-VR8-M00, 08720-VR8-M01, and 08720-VR8-M02. It includes both the upper and lower blades, so you don’t need to buy them separately. Measure your existing blade length (approximately 21 inches) and center hole diameter (usually 7/8-inch) to verify fit. If you have an older HRB model not listed, cross-reference your blade’s part number with the replacements above.

Key Things to Know

• Installation difficulty: Easy bolt-on. Requires a socket or wrench to remove the center bolt and blade nut. No special tools needed beyond a blade removal tool or block of wood to hold the blade.
• Precision balanced: Blades are factory-balanced, which reduces vibration and strain on the spindle. No need to rebalance unless you damage them during installation.
• Hardened steel edge: Stays sharp longer than standard steel, but still requires periodic sharpening (every 5-10 hours of use) for clean cuts.
• Common gotcha: The upper and lower blades are different lengths. The upper blade is shorter; do not swap them. Mark or label each before removal to avoid mix-ups.

Should You Buy It

If you own a Honda HRB215, HRB216, or HRB217 and want a direct OEM-replacement blade set with proven durability and a perfect fit, this is a solid buy. The hardened steel and balanced design make it ideal for homeowners or pros who mow frequently and want consistent cuts without aftermarket guesswork.
