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 (1 Pack)

What It Is

This is a 20-inch replacement lawn mower blade with oval center holes, designed for walk-behind mowers. It fits specific Oregon, Daye, and Hyper Tough models, as well as EGO models MNA152505, MNA152701, and MNA152516. It replaces OEM part 101000001.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This blade is 20 inches long. Confirm your mower’s deck is exactly 20 inches (measure from blade tip to tip, not deck shell).
• Center hole shape: Oval center holes are required. Round hole blades will not fit.
• Model numbers: Direct fit for EGO MNA152505, MNA152701, MNA152516. Also compatible with Oregon 20” decks, Daye, and Hyper Tough mowers that use a 20” oval hole blade.
• Replaces: OEM part 101000001. If your current blade has that number, this is a drop-in replacement.

Check your mower’s model number (usually on a sticker under the deck or on the frame) to confirm compatibility. Do not rely solely on brand name—measure and verify.

Key Things to Know

• Quality: Aftermarket blade, not OEM. Expect reasonable durability for residential use, but may not last as long as EGO factory blades under heavy or frequent mowing.
• Installation: Straightforward—remove the old blade, note the orientation (sharp edge facing forward), and torque the center bolt to 30-40 ft-lbs. Use a blade removal tool or block the blade with wood for safety.
• Common gotcha: The oval hole orientation must match your mower’s spindle. If the hole is too tight or misaligned, the blade will wobble or fail to seat. Check fit before tightening.
• Pack includes: 1 blade only. No hardware (bolt/washer) included—reuse your old ones or buy separately if worn.

Should You Buy It

Buy this if you need a budget-friendly, direct replacement for a 20” oval hole blade on an EGO, Oregon, Daye, or Hyper Tough mower and don’t require OEM longevity. It’s a solid value for residential lawns, but for heavy commercial use or if you want maximum lifespan, stick with an OEM EGO blade.
