Hipa 08720-vh7-000 Mulching Blade Set for Hon-da HRR2169 HRR2169VKA HRX217 HRX537 GCV160 Series 21 Inch Walk-Behind Mower 72531-VH7-000 & 72511-VH7-000 Blade Kit

What It Is

This is a three-blade mulching kit designed to replace the OEM Honda blades on 21-inch walk-behind mowers. It’s specifically for fine grass clipping shredding and nutrient recycling, not bagging or side-discharge.

Fitment & Compatibility

Before buying, verify your mower has a 21-inch cutting deck. This set fits Honda HRR2169, HRR2169VKA, HRX217, HRX537, and GCV160 series models. The kit replaces OEM part numbers 72531-VH7-000 (left) and 72511-VH7-000 (right). Measure your existing blade length and center hole diameter — these are typically 21 inches long with a 7-point star center hole. Check your mower’s model number on the deck sticker; cross-reference with Hipa’s compatibility list if unsure. This is an aftermarket set, not OEM Honda, so blade thickness and balance may differ slightly.

Key Things to Know

• Installation requires a torque wrench. Tighten the blade bolt to 35-40 ft-lbs (Honda spec). Over-torquing can strip the adapter; under-torquing risks blade detachment.
• Balance-check before mounting. Hipa blades sometimes need minor balancing. Use a blade balancer or a nail in the wall; file the heavy end if needed.
• Mulching performance is best with dry, short grass. Wet or tall grass will clump and strain the engine. Raise deck height to 2-3 inches for first pass.
• Sharpening is possible but limited. The blade’s heat-treated edge can be filed, but the thin profile wears faster than OEM. Expect 1-2 seasons of moderate use before replacement.

Should You Buy It

Buy this if you own a compatible 21-inch Honda and want a cost-effective mulching upgrade that outperforms standard bagging blades. Skip it if you need OEM durability for heavy commercial use or prefer a universal blade set.
