Stens 355-101 Standard Blade Compatible with/Replacement for Hyper Tough MNA152701 mowers 2105300125A 20" Length, 0.125" Thickness, 2 1/4" Width, 1" x 3/4" Center Hole

What It Is

This is a 20-inch standard replacement blade for Hyper Tough MNA152701 push mowers, designed to replace OEM part 2105300125A. It’s meant for basic mulching and bagging on residential lawns.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be a 20-inch cutting deck. Measure your current blade tip-to-tip (not the deck housing).
• Center hole: This blade has a 1-inch round hole with a 3/4-inch D-shaped insert. Ensure your mower’s spindle matches this (common on Hyper Tough models).
• Model number: Confirmed fit for Hyper Tough MNA152701. Also fits some MTD/Craftsman models with the same hole pattern—cross-check your mower’s model number with Stens fitment charts.

Check your blade measurements: Thickness is 0.125" (standard), width 2.25". If your current blade is thicker or wider, this may not fit or could affect performance.

Key Things to Know

• Quality: Stens is a known aftermarket brand—blade is heat-treated and balanced. Expect similar durability to OEM, but not heavy-duty.
• Installation: Straightforward swap. Use a torque wrench (30-40 ft-lbs) to avoid stripping the bolt. The D-hole centers the blade automatically—no centering tool needed.
• Common gotcha: The 1" round hole with D-flat is not universal. Some Hyper Tough models use a 1" round hole only—check your spindle before buying. If your blade has a 5-point star hole, this won’t fit.
• Performance: Good for standard grass cutting. Not ideal for thick, wet grass or heavy mulching—blade may dull faster.

Should You Buy It

If you own a Hyper Tough MNA152701 (or compatible model) and need a reliable, budget-friendly replacement for regular residential mowing, this is a solid choice. Avoid if your spindle requires a different hole shape or you need a heavy-duty blade for tough conditions.
