Grasscool 2105300125A 20 Mower Blade Compatible with Hyper Tough Murray 20 inch MNA152505 MNA152701 Push Mower(Oval Center Hole)

What It Is

The Grasscool 2105300125A is a 20-inch replacement blade designed for 20-inch Hyper Tough and Murray push mowers with an oval center hole. It’s for standard residential grass cutting on flat or mildly uneven lawns.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 20 inches (measure from blade tip to tip). This blade fits Hyper Tough models MNA152505 and MNA152701, plus Murray models using the 2105300125A OEM part. The oval center hole must match your mower’s crankshaft—measure the hole length and width. It is not compatible with round hole or star-shaped spindles. Check your owner’s manual or measure the old blade’s hole shape and size. Aftermarket part, not OEM Murray.

Key Things to Know

• Quality: Grasscool blades are budget-friendly but may be thinner or less durable than OEM; inspect for bending after heavy use.
• Installation: Moderate difficulty—you’ll need a socket wrench and blade removal tool. Torque the center bolt to 30-40 ft-lbs. Ensure the blade spins freely after tightening.
• Common gotcha: The oval hole orientation matters—align it with the spindle’s flat sides. Wrong orientation causes wobble and poor cut.
• Sharpness: Comes pre-sharpened but edges may dull faster than premium blades; sharpen after 10-15 hours of use.

Should You Buy It

If you own a compatible 20-inch Hyper Tough or Murray push mower and need an affordable, functional replacement for standard grass, this blade works. But if you mow thick, wet, or rocky terrain, consider a thicker OEM blade for better longevity and cut quality.
