One 21" Walk Behind Mower Blade Fits Huskee Fits Yardman Fits Bolens Fits Murray

What It Is

This is a single 21-inch replacement blade for walk-behind lawn mowers, designed for standard residential cutting on turf. It fits multiple brands including Huskee, Yardman, Bolens, and Murray.

Fitment & Compatibility

Before buying, confirm three things: your mower deck size must be 21 inches (measure from blade tip to tip, not deck width). Check the blade’s center hole diameter and shape—most Murray/Huskee/Yardman models use a 5-point star or 7-point star center hole, but some use a round hole with a 1-inch diameter. Also measure blade length (cutting swath) and ensure it’s exactly 21 inches end to end. This is an aftermarket blade, not OEM, so verify that your mower’s spindle and blade adapter match the blade’s mounting pattern. Common compatible model series include Murray 21-inch Select, Huskee 21-inch Supreme, and Yardman 21-inch push mowers from the 2000s onward.

Key Things to Know

• Quality: 4.4 stars from 57 reviews suggests decent build, but check for reported balance issues—some aftermarket blades need balancing before installation.
• Installation: Easy if you have a socket wrench and blade removal tool. Always disconnect the spark plug wire first. Torque the blade bolt to 30-40 ft-lbs (check your manual).
• Common Gotcha: The blade may be slightly thicker than OEM, requiring you to also replace the blade adapter or washer if your old one is worn. Also, verify the blade’s air lift (curved ends) matches your deck design—flat decks need a high-lift blade, mulching decks need a low-lift.
• Sharpness: It arrives unsharpened or with a factory edge—you’ll likely need to sharpen it before first use for best cut quality.

Should You Buy It

If you have a 21-inch walk-behind mower from Huskee, Yardman, Bolens, or Murray, and you’ve confirmed the center hole match (star or round), this is a solid budget-friendly replacement. It’s not for commercial use or mulching-specific decks, but for standard side-discharge or bagging mowers, it’ll get the job done. Avoid if you need OEM-specific blade geometry or have a newer model with a unique mounting system.
