72531-VR8-M00 & 72511-VR8-M00 Mower Blades Set Compatible with Hon da HRB215 HRB216 HRB217 HRM215 HRR216 HRS216 HRT216, Fit 21" Deck Push and Propelled Lawn Mower, 2 Pack

What It Is

This is a 2-pack of replacement mower blades (part numbers 72531-VR8-M00 and 72511-VR8-M00) designed for 21-inch deck Honda push and self-propelled mowers, specifically the HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, and HRT216 series. They serve as a direct cut-and-lift replacement for worn OEM blades.

Fitment & Compatibility

Before buying, measure your existing blade length—must be exactly 21 inches (from tip to tip). Confirm your mower deck is 21 inches (not 20” or 22”). These are aftermarket blades, not Honda OEM, but match the original mounting hole pattern and offset. Check that your mower model is one of the listed series (e.g., HRB215, HRR216, HRT216—check the model tag under the seat or on the deck). Do not use on older Honda models with different blade part numbers (e.g., 72511-VE2-000). Verify your blade bolt size (usually 5/16” or 3/8”) fits the center hole—these blades typically use a 5/16” bolt.

Key Things to Know

• Quality: Aftermarket steel, likely not heat-treated as aggressively as OEM. Expect shorter edge life but acceptable cutting for residential use.
• Installation: Straightforward if you have a socket wrench and blade removal tool. Note the blade orientation—the curved ends must face upward toward the deck for proper lift.
• Common Gotcha: The set includes one left-hand and one right-hand blade (marked L and R). Install the correct side—mixing them up causes severe vibration and poor cutting.
• Bolt Torque: Tighten to 30-40 ft-lb. Overtightening can strip the blade adapter; under-tightening risks the blade flying off.

Should You Buy It

Buy this set if you have a compatible 21-inch Honda push or self-propelled mower and want a budget-friendly replacement that matches OEM specs. It’s a solid value for residential lawns, but if you mow heavy grass weekly or need maximum durability, consider OEM blades for longer life.
