Honda 72511-VA2-690 PK2 Lawnmower Blades

What It Is

The Honda 72511-VA2-690 PK2 is a set of two OEM (Original Equipment Manufacturer) mulching blades designed specifically for select Honda HRX-series lawn mowers. These blades are engineered to chop grass clippings finely for mulching, leaving no visible clumps behind.

Fitment & Compatibility

Before buying, confirm your mower model. These blades fit Honda HRX217 models with a 21-inch deck, including HRX217HMA, HRX217VKA, HRX217VLA, HRX217VYA, and HRX217K5VKAA. They will not fit HRX models with a 20-inch deck or any non-Honda mower. Measure your existing blade length—it must be 21 inches (533 mm) from tip to tip. The center hole is a standard 1-inch (25.4 mm) diamond shape. These are genuine Honda parts, so aftermarket blades (e.g., Oregon, Stens) may differ in thickness or balance. Always check your mower’s serial number or owner’s manual for exact model compatibility.

Key Things to Know

• Quality: These blades are heat-treated, hardened steel with a balanced design. They last longer than most aftermarket options and resist bending or chipping.
• Installation: Moderate difficulty. You’ll need a socket wrench (usually 15mm or 5/8 inch) and a blade removal tool or block of wood to prevent spinning. Torque to 30-35 ft-lbs. Always disconnect the spark plug and drain fuel first.
• Common Gotchas: These are mulching blades only—they don’t bag or side-discharge well. If you switch to bagging, you’ll need Honda’s separate bagging blade set. Also, check the blade adapter (part 72531-VA2-000) for wear; a worn adapter can cause vibration or uneven cut.
• Sharpness: Blades come sharp but dull faster in sandy soil or with frequent mulching. Sharpen or replace every 25-30 hours of use.

Should You Buy It

Buy this if you own a compatible Honda HRX217 with a 21-inch deck and want OEM-quality mulching performance with minimal clumping. It’s ideal for homeowners who prioritize a clean, finely mulched lawn and are willing to pay a premium for genuine Honda reliability. Skip it if you need bagging or side-discharge blades, or if you have a different mower brand.
