72511-VR8-M00 Bottom Blade and 72531-VR8-M00 Upper Blade Set Replacement for Honda HRN216 VKA PKA VLA VYA PKAA 21-Inch Deck

What It Is

This is a genuine OEM blade set for Honda HRN216 series mowers, designed to replace both the lower (72511-VR8-M00) and upper (72531-VR8-M00) blades on select 21-inch deck models. It’s intended for residential mulching and bagging use, not for heavy commercial cutting.

Fitment & Compatibility

• Deck size: Fits 21-inch Honda HRN216 decks only. Not compatible with other deck sizes or brands.
• Model variants: Confirmed fit for HRN216VKA, HRN216PKA, HRN216VLA, HRN216VYA, HRN216PKAA. Check your model number on the mower’s ID tag (under the rear flap or on the frame).
• OEM vs aftermarket: This is a genuine Honda part. Aftermarket blades may require spacer adjustments or not match the blade offset—stick with OEM for guaranteed fit.
• Measurement check: Lower blade is ~21” long, upper is ~15.5” long. Both have a 5-point star center hole. Measure your existing blades to confirm length and hole shape before ordering.

Key Things to Know

• Installation is straightforward if you’ve changed blades before—just remove the center bolt (likely 14mm or 15mm), swap blades, and torque to 35-45 ft-lbs. No special tools needed beyond a socket wrench and blade stop.
• Upper blade orientation matters: The upper blade’s cutting edge faces the direction of rotation (clockwise when viewed from above). Install it upside down and you’ll get poor cutting and vibration.
• Blade set includes both blades, but no hardware. If your bolts are rusted or stripped, order new ones (Honda part 90111-VR8-M00).
• Quality is typical Honda OEM—balanced, sharp, and durable for residential use. Expect 25-50 hours of cutting life depending on grass type and debris.

Should You Buy It

Buy this if you own one of the listed HRN216 models and want a hassle-free, guaranteed fit with OEM durability. Skip it if you’re on a budget—aftermarket sets cost about half as much but may require filing or shimming. For most homeowners, the extra cost is worth avoiding vibration and poor cut quality.
