2105300125A Lawnmower Blade Replacement for Hyper Tough Push Mower Parts - 20" Lawn Mower 101000001 Blade Replace for Stens 355-101 Standard Blade Compatible with HyperTough MNA152505 MNA152701

What It Is

This is a 20-inch replacement blade for Hyper Tough push mowers, designed for standard mulching and bagging use on residential lawns. It fits models like MNA152505 and MNA152701.

Fitment & Compatibility

Before buying, confirm three things: deck size must be 20 inches (measure cutting width, not blade length), blade length must be exactly 20 inches (center hole to tip), and center hole diameter must match your spindle (typically 1-inch round or star-shaped on Hyper Tough). This blade replaces OEM part 101000001 and Stens 355-101. It is not compatible with 21-inch or 22-inch decks, or with Craftsman, Toro, or Honda spindles without adapter. Check your mower’s model number (e.g., MNA152505) under the deck or on the engine cowl.

Key Things to Know

• Quality: 4.8/5 rating from 45 reviews suggests good durability for residential use, but it’s a budget aftermarket blade—expect less edge retention than OEM.
• Installation: Easy if you have a socket wrench and a block of wood to jam the blade. Torque bolts to 30-35 ft-lbs; over-tightening can strip the spindle.
• Common gotcha: Some users report the blade is slightly thinner than OEM, which can cause vibration. Balance it on a screwdriver before mounting; if one side dips, file the heavy side.
• Sharpening: Can be sharpened 2-3 times, but the steel is softer than premium blades—replace after hitting rocks or roots.

Should You Buy It

Yes, if you have a 20-inch Hyper Tough push mower and want a cheap, reliable drop-in replacement with good reviews. Skip it if you need heavy-duty mulching, commercial durability, or if your mower uses a different spindle hole size—measure first to avoid returns.
