2105300125A Lawn Mower Blade with Oval Center Holes, Compatible with Hyper Tough 20inch Mower Blade, 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 Hyper Tough push mowers. It’s meant for standard residential grass cutting, not mulching or bagging specifically.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be a 20-inch cutting deck. Measure your deck width if unsure.
• Model numbers: Confirmed fit for Hyper Tough models MNA152505, MNA152701, and MNA152516. Check your mower’s model tag (usually under the deck or on the top housing).
• Oval center hole: This blade uses oval holes (not round) and replaces OEM part numbers 101000001 and Blade 2105300125A. It will not fit mowers with round center holes or different hole spacing.
• Aftermarket note: This is not an OEM Hyper Tough blade—it’s a compatible replacement. Quality and balance may vary from the original.

Key Things to Know

• Sharpness out of box: Most users report it’s sharp enough for 1-2 cuts, but you may need to sharpen it sooner than an OEM blade.
• Installation: Straightforward—remove the old blade (wear gloves), align oval holes with the adapter, and torque to 30-40 ft-lbs. No special tools beyond a socket wrench.
• Balance check: Aftermarket blades can be slightly unbalanced. Test by hanging the blade on a nail; if one side dips, it will cause vibration and uneven cut. You may need to file the heavy side.
• Durability: Made from standard carbon steel—fine for occasional mowing but may dull faster on thick or wet grass compared to hardened steel blades.

Should You Buy It

If you own one of the listed Hyper Tough models and need a quick, budget-friendly replacement for a worn or dull OEM blade, this will work. It’s best for light-to-medium duty residential use. Skip it if you want premium longevity or a perfect factory balance—go with an OEM blade instead.
