72511-VR8-M00&72531-VR8-M00 Mower Blade Kit Compatible with Honda HRN216 HRN216VKA HRN216PKA Lawn Mower, 21" Microcut Twin Blade Kit with 17211-Z8B-901 Air Filter Spark Plug

What It Is

This is a genuine Honda MicroCut twin blade kit (part numbers 72511-VR8-M00 & 72531-VR8-M00) designed for 21-inch Honda HRN216 series mowers. It includes two blades, a blade bolt, and a washer, plus a 17211-Z8B-901 air filter and spark plug as a bundled maintenance kit.

Fitment & Compatibility

• Deck size: 21-inch cutting deck only. Measure your blade length—these are 21 inches total (each blade ~10.5 inches).
• Models confirmed: Honda HRN216VKA, HRN216PKA, HRN216VLA, HRN216VYA, HRN216VMA. Check your mower’s model number (sticker under seat or on deck).
• OEM vs aftermarket: These are genuine Honda parts, not aftermarket. They match OEM specs exactly.
• What to verify: Ensure your mower uses the MicroCut twin blade system (two overlapping blades, not a single bar blade). Also check that the center hole diameter is 1 inch and the bolt pattern matches your spindle.

Key Things to Know

• Installation difficulty: Easy—requires a wrench and blade removal tool. Torque blade bolt to 30–35 ft-lbs. The air filter and spark plug are straightforward swaps.
• Blade orientation: The curved edge faces upward toward the deck. Both blades must be installed with the cutting edge facing the same direction.
• Performance: MicroCut blades produce finer clippings for mulching and better bagging. They dull faster than standard blades on thick, wet grass.
• Bundled extras: The included air filter and spark plug are compatible with Honda GCV200 engines. If your mower uses a different engine, verify before buying.

Should You Buy It

Buy this if you own a Honda HRN216 series mower and want OEM-grade twin blades for the best mulching and bagging performance. It’s a solid value for a full maintenance kit, but skip it if you need a single bar blade or have a different deck size—measure first.
