72531-VR8-M00&72511-VR8-M00 21" Mower Blade Kit Compatible with Hon da HRB215 HRB216 HRB217 HRM215 HRR216 HRS216 HRT216 Push and Propelled Lawn Mower

What It Is

This is a set of two 21-inch mower blades (part numbers 72531-VR8-M00 and 72511-VR8-M00) designed to replace OEM blades on select Honda push and self-propelled mowers with a 21-inch cutting deck. It’s for standard mulching or bagging use, not for commercial zero-turn or riding mowers.

Fitment & Compatibility

• Deck size: Only fits 21-inch cutting decks. Do not use on 20-inch or 22-inch decks.
• Compatible Honda models: HRB215, HRB216, HRB217, HRM215, HRR216, HRS216, HRT216 (both push and self-propelled variants). Check your model number on the mower’s deck or frame—not just the engine.
• OEM vs aftermarket: These are aftermarket blades, not Honda Genuine. They match OEM dimensions and hole patterns (center hole and offset), but quality and steel thickness may vary slightly. If you need exact OEM fit, buy Honda-branded blades.
• Measure before buying: Lay your current blade flat. Measure length (must be 21 inches), center hole diameter (typically 7/8-inch), and offset (how much the blade is bent up at the ends). If these match, these blades will fit.

Key Things to Know

• Quality: At $30.39 for a pair, these are budget-friendly. Expect decent steel but possible faster dulling than OEM Honda blades. Sharpen after 10–15 hours of use.
• Installation difficulty: Easy—remove the bolt, replace the blade, torque to 30–35 ft-lbs. Use a blade stop or block of wood to prevent spinning. Always disconnect the spark plug first.
• Common gotchas: The blade set may not include a center bolt or washer—reuse your old hardware. Some users report the blades are slightly thinner than OEM, which can cause vibration if not balanced. Check balance with a blade balancer before installing.
• Performance: Works well for mulching and bagging on dry grass. Avoid heavy wet grass to prevent clumping—these blades lack the air-lift design of premium options.

Should You Buy It

Buy this if you own one of the listed Honda 21-inch mowers and want a low-cost replacement for standard residential mowing. Skip it if you need extreme durability for commercial use, or if you prefer exact OEM parts—spend extra on Honda brand blades for better steel and longer edge life.
