Parts Manuf. 2105300125A Blade 20" Daye/Hyper Tough MNA152701. Case of 2

What It Is

This is a 20-inch replacement blade set (case of 2) designed for Daye and Hyper Tough push mowers, model MNA152701. It’s a direct replacement for cutting grass on standard residential lawns, not for mulching or bagging-specific setups.

Fitment & Compatibility

• Deck size: Must be exactly 20 inches (measure blade tip to tip; do not guess).
• Model fit: Confirmed for Daye/Hyper Tough MNA152701 only. Not compatible with other brands or models unless verified.
• OEM vs aftermarket: This is an aftermarket blade from Parts Manuf., not OEM. Check that your mower’s spindle hole pattern matches (usually a 5-point star or oval center hole).
• Measurements before buying: Verify blade length (20"), center hole diameter (typically 1" or 7/8"), and thickness (usually 0.125–0.150"). Measure your old blade with a ruler or calipers.

Key Things to Know

• Quality: 4.6 stars from 46 reviews suggests good durability for residential use. No reports of bending or breaking on normal lawns.
• Installation difficulty: Easy—remove spark plug, tilt mower, unbolt old blade (left-hand thread on some models), install new one with blade bolt torque of ~40-50 ft-lbs. Use a blade removal tool or block of wood to prevent spinning.
• Common gotcha: The 20-inch length is critical. A 21" blade will not fit; a 19" blade will leave uncut strips. Also, ensure the blade orientation (lift edge facing up) matches your mower’s deck design.
• Pairing: Comes as a case of 2, so you can replace both blades at once (if your mower uses two) or save one for next season.

Should You Buy It

If you own a Daye or Hyper Tough MNA152701 with a 20-inch deck and need a reliable, affordable blade set for regular lawn cutting, this is a strong choice. The high rating and low price make it a no-brainer for most homeowners, but double-check your spindle hole pattern before ordering.
