2105300125A Lawn Mower Blade with Oval Center Holes, Compatible with 20" Oregon, Daye/Hyper Tough Lawn Mower Deck, Fit for MNA152505, MNA152701, MNA152516, Replaces 101000001 (2 Pack)

What It Is

This is a 2-pack of 20-inch lawn mower blades with oval center holes, designed for 20" cutting decks. It’s a direct replacement for OEM blade 101000001 and fits select Oregon, Daye, and Hyper Tough mowers, as well as models MNA152505, MNA152701, and MNA152516. Best for residential mowing on standard turf.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 20 inches. Measure blade length from tip to tip—20” is critical. Check that your spindle uses an oval center hole (not round or star-shaped). This blade replaces OEM part 101000001, so if your current blade has that number, it’s a match. Verified compatible with Oregon 20” decks, Daye/Hyper Tough 20” models, and the specific MNA series listed. Not for 21” or 22” decks, or mowers with round center holes.

Key Things to Know

• Quality: Steel is heat-treated and coated for rust resistance. Users report good balance out of the box—no major vibration.
• Installation: Simple bolt-on if your mower uses a single center bolt. Use a torque wrench to 35-45 ft-lbs. Blade orientation: lift wings point up toward deck.
• Gotcha: Oval hole orientation matters—align it with your spindle’s flat sides. If your mower uses a different hole shape, this won’t work.
• Durability: Holds edge for a season on normal grass. Avoid rocks and thick weeds to prevent chipping.

Should You Buy It

If you own a 20” Oregon, Daye, or Hyper Tough mower (or one of the listed MNA models) and need a reliable, affordable replacement blade pair, this is a solid choice. It’s well-rated, fits common residential decks, and offers good value at $30.99 for two blades. Not for heavy commercial use or non-standard center holes.
