72511-VE1-020 & 72531-VE2-020 21" Lawn Mower Blade Set for HRB215 HRB216 HRB217 HRM215 HRR216 HRS216 HRT216 HRZ216, Replace 72511-VE1-010(Upper),72531-VE2-010(Lower)

What It Is

This is a two-blade set (upper blade 72511-VE1-020 and lower blade 72531-VE2-020) designed for Honda 21-inch walk-behind mowers. It’s a direct replacement for OEM blades, suited for standard residential lawn cutting and mulching on Honda HRB, HRM, HRR, HRS, HRT, and HRZ series mowers.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck and is one of these Honda models: HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, HRT216, or HRZ216. This set replaces OEM part numbers 72511-VE1-010 (upper) and 72531-VE2-010 (lower). Measure your existing blades: the upper blade is typically 21 inches long with a 5-point star center hole; the lower blade is shorter (about 15 inches) with the same star hole. Check the blade mounting bolt pattern—these use a 5-point star, not a round hole. This is an aftermarket set, not genuine Honda, so verify blade thickness (around 0.135 inches) matches your OEM specs to avoid fitment issues with the spindle.

Key Things to Know

• Quality vs OEM: These are aftermarket blades, likely steel with a painted finish. They may not hold an edge as long as genuine Honda blades, but they’re a budget-friendly alternative for regular use.
• Installation difficulty: Easy—requires a socket wrench and a block of wood to lock the blade. Torque bolts to 30-40 ft-lbs. Note the upper and lower blades are different lengths; don’t swap them.
• Common gotcha: The 5-point star hole can be tight on some Honda spindles. If it doesn’t seat fully, don’t force it—file the hole slightly or return the set.
• Balance check: Aftermarket blades are often unbalanced out of the box. Always balance the set before installing to avoid vibration and spindle wear.

Should You Buy It

This set is a solid choice if you own a compatible Honda 21-inch mower and need a cost-effective replacement for worn OEM blades. It’s not ideal for heavy-duty mulching or commercial use—stick with genuine Honda blades for that. For standard residential cutting, this is a reliable, budget-friendly option that fits well and performs adequately.
