72531-VH7-000 & 72511-VL0-S00 Mulching Blades Kit Compatible with Honda HRR216 HRX217 HRN216, Complete Maintenance Kit with Air Filter Spark Plug Oil Filter Tool

What It Is

This is a complete maintenance kit for Honda walk-behind mowers, combining two mulching blades (OEM part numbers 72531-VH7-000 and 72511-VL0-S00) with an air filter, spark plug, and oil filter. It’s designed for one-stop service on Honda HRR216, HRX217, and HRN216 series mowers.

Fitment & Compatibility

• Deck size: Fits 21-inch cutting decks only. Check your deck’s stamped size before ordering.
• Model series: Confirmed for HRR216 (all sub-models), HRX217 (all sub-models), and HRN216 (all sub-models). Not compatible with HRC, HRS, or commercial-series mowers.
• OEM vs aftermarket: These blades are genuine Honda parts, not aftermarket copies. The air filter, spark plug, and oil filter are also OEM-spec (filter part 15400-PLM-A02, plug part 98079-55856, spark plug gap 0.028-0.031 in).
• Measurements: Blade length is 21 inches, center hole diameter is 1 inch, with a 5-point star drive. Verify your current blades match these dimensions.

Key Things to Know

• Low rating warning: 2.8 stars from 6 reviews suggests inconsistent quality control or packaging issues. Some buyers report blades arriving bent or with dull edges.
• Installation difficulty: Moderate. You’ll need a socket wrench and torque wrench (blade bolt torque: 33-37 ft-lbs). The star drive requires a compatible tool (often a 5-point star bit). Not a quick swap if you’re new.
• Common gotcha: The kit includes mulching blades only. If you need bagging or side-discharge blades, this won’t work. Also, the oil filter is for the GCV160/190 engine—double-check your engine model (stamped on the blower housing).
• Value check: At $44, buying the blades alone costs ~$30, so the filters and plug add ~$14. Decent value if all parts are genuine and functional.

Should You Buy It

Buy this kit only if you need a complete, OEM-spec refresh for your Honda HRR/HRX/HRN and want the convenience of one order. But given the low ratings, inspect everything immediately upon arrival—return it if blades are damaged or parts are wrong. For a simpler mulching blade upgrade, consider a standalone set from Oregon or Maxpower with better reviews.
