Wadoy 2105300125A Blade, MNA152505 MNA152701 Lawn Mower Blade Compatible with Hyper Tough 20 Inch Mower Blade | Heavy Duty Steel Construction Powder Coated Surface Tungsten Carbide Reinforced Edge Clean Cut Blade Geometry

What It Is

This is a 20-inch replacement blade for walk-behind push mowers, specifically designed for Hyper Tough models MNA152505 and MNA152701. The blade features a tungsten carbide reinforced edge for longer life and a clean-cut geometry to improve grass lift and mulching performance.

Fitment & Compatibility

Before buying, confirm your mower has a 20-inch deck (measure from blade tip to blade tip). This blade is a direct aftermarket replacement for OEM part number 2105300125A. It fits Hyper Tough models MNA152505 and MNA152701 only—not other Hyper Tough or generic 20-inch mowers. Check your current blade’s center hole diameter (must match) and ensure the blade length is exactly 20 inches. If your mower uses a different spindle or offset pattern, this blade won’t work.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool (or wood block) to lock the blade. Always disconnect the spark plug first.
• Quality: Heavy-duty steel with a powder-coated surface resists rust, and the tungsten carbide edge stays sharp longer than standard steel blades. Expect 2-3 seasons with normal use.
• Common gotcha: The blade is not reversible—the tungsten carbide edge is on one side only. Install with the cutting edge facing the direction of rotation (usually marked with an arrow on the blade).
• Balance check: After installation, spin the blade by hand to ensure it’s balanced. An unbalanced blade causes vibration and can damage the spindle.

Should You Buy It

If you own a Hyper Tough MNA152505 or MNA152701 and want a durable, long-lasting blade that cuts cleanly and resists dulling, this is a solid upgrade over standard steel. It’s not for other mower brands or deck sizes, and installation requires basic mechanical confidence. For the price, the tungsten carbide edge offers real value for frequent mowers.
