72531-VH7-000 & 72511-VL0-S00 Mulching Blades Kit for Honda HRX217, Complete Tune-Up Kit with 2 Air Filters 17211-ZL8-023, Spark Plug, Bolts, Washer & Socket Tool

What It Is

This is a complete tune-up kit for Honda HRX217 mowers, combining two OEM-style mulching blades (72531-VH7-000 & 72511-VL0-S00) with two air filters (17211-ZL8-023), a spark plug, blade bolts, washers, and a socket tool. It’s designed for owners who want to refresh cutting performance and engine maintenance in one purchase.

Fitment & Compatibility

• Mower models: Honda HRX217 series (all sub-models: VKA, VLA, TDA, TYA, HYA, HMA, etc.). Not for HRX216 or older HRX versions.
• Deck size: 21-inch stamped steel deck. Confirm your deck is 21” and not the 20” variant found on some older HRX models.
• OEM vs aftermarket: Blades are genuine Honda parts; air filters and spark plug are OEM-spec replacements. Aftermarket blades may fit but won’t match the exact balance or lift profile.
• Measurements: Blade length is 21 inches, center hole diameter is 1 inch. Bolt size is 5/16” x 1” with flange lock washer. Check your current blade bolts for wear—this kit includes new ones.
• Air filter compatibility: 17211-ZL8-023 fits HRX217 and many Honda twin-blade mowers. Not for HRX217 with the older foam-only filter.

Key Things to Buy

• Quality: Blades are OEM Honda—sharp, balanced, and coated for rust resistance. Air filters are paper-element, not reusable foam. Spark plug is standard NGK or equivalent.
• Installation difficulty: Easy for a DIYer with basic tools (socket wrench, torque wrench recommended). The included socket tool helps with the blade bolt.
• Common gotchas:
  • Torque blade bolts to 30-35 ft-lbs—under-torquing can cause blade detachment, over-torquing strips threads.
  • Mulching blades are not for bagging or side-discharge; they rely on the deck’s internal baffle.
  • Air filter orientation matters—arrow on filter points toward carburetor.
  • Spark plug gap is pre-set, but verify it’s 0.028-0.031” before installing.

Should You Buy It

If you own a Honda HRX217 and want a one-stop tune-up with genuine mulching blades, this kit saves money over buying parts separately and ensures everything fits. It’s ideal for homeowners who mulch regularly and want reliable performance without hunting for individual pieces. Skip it if you need bagging or side-discharge blades, or if your HRX217 is a pre-2010 model with a different deck.
