What It Is

This is an OEM replacement lower mulching blade for select Honda HRC216 commercial mowers, designed to pair with the 325-104 upper mulching blade. It fits models HRC216K2 HXA, HRC216K2 PDA, HRC216K3 HXA, and HRC216K3 PDA, and replaces Honda part number 08720-VH7-000.

Fitment & Compatibility

Before buying, confirm your mower deck is the 21-inch Honda HRC series (not the residential HRR or other models). Check your mower’s model number on the frame tag—this blade only fits the K2 and K3 variants listed. You must also verify you have or will purchase the upper mulching blade (OPE# 325-100), as this lower blade works only as part of a two-blade mulching system. Measure your existing blade length (approx. 21 inches overall) and center hole diameter (typically 1 inch) to ensure match. This is an OEM Honda part, so aftermarket alternatives may differ in thickness or balance.

Key Things to Know

• Low review rating (3.1/5) – Only 2 reviews exist, so take the score with caution; OEM quality is generally reliable but limited feedback means unknown long-term performance.
• Installation difficulty – Moderate. You’ll need a socket wrench and blade removal tool. Torque the blade bolt to 35-45 ft-lb. Always disconnect spark plug first.
• Common gotcha – Forgetting the upper blade. This lower blade alone won’t mulch effectively; it’s designed as a set. Using just one blade may cause poor cut or vibration.
• Sharpening – OEM blades are heat-treated; sharpening is possible but reduces lifespan. Replace if bent or chipped.

Should You Buy It

Buy this if you own one of the listed Honda HRC216 models and need an exact OEM replacement for the lower mulching blade in a two-blade setup. It’s right for users prioritizing factory fit and durability over aftermarket cost savings. Skip it if you don’t have the upper blade or if you’re looking for a single-blade mulching solution—this part requires the pair to function properly.
