Before you choose
How to Choose the Right Hyper Tough 20-Inch Mower Blade
Choosing the correct blade for your 20-inch mower requires checking physical dimensions, center mounting configurations, and deck design before making a selection. Walk-behind mowers in this class rely on balanced rotational forces, meaning an incorrect center hole pattern or improper length will cause severe vibration, uneven cutting, or engine spindle damage.
The primary fitment detail on these models is the center mounting hole. Most Hyper Tough 20-inch mowers utilize an oval center hole measuring 1 inch by 3/4 inch, flanked by two circular alignment holes spaced 2-1/8 inches center-to-center. Products like the UDC Parts 2105300125A Lawn Mower Blades, Grasscool 2105300125A 20 Mower Blade Compatible, and Upgrade 355-101 20″ Lawn Mower Blades,Replace all follow this standard oval geometry. If your spindle requires a three-hole layout, the Hyper Tough 20-Inch Standard Discharge Mower blade matches standard gas walk-behind decks.
Cross-referencing part numbers ensures seamless installation. Common part numbers for 20-inch Hyper Tough, Daye, and Murray push mowers include 2105300125, 2105300125A, 101000001, and 355-101. Common model numbers include MNA152505, MNA152516, and MNA152701. Always verify the model stamped on your deck housing or listed in your user manual before ordering.
Finally, consider how many blades you need. If your lawn has rocky patches or you travel frequently during summer months, multi-packs like the two-count UDC Parts or the three-count Upgrade 355-101 ensure a clean backup is ready in the shed. For simple one-off repairs, single blades from Grasscool or Parts 2105300125A provide an efficient solution.
Questions people ask
FAQ
Which blade fits hyper tough 20 inch mower decks?
A 20-inch blade featuring a 1-inch by 3/4-inch oval center hole and a 2-1/8-inch center-to-center outer pin spacing fits most Hyper Tough 20-inch walk-behind mowers. Compatible part numbers include 2105300125, 2105300125A, and 101000001 across models MNA152505, MNA152516, and MNA152701.
What is the difference between part numbers 2105300125 and 2105300125A?
Part number 2105300125 represents the original base part specification for 20-inch Hyper Tough gas walk-behind decks, while 2105300125a blade designations denote updated factory revisions or OEM cross-references. Both numbers share compatible 20-inch deck geometry and mounting configurations across Daye and Hyper Tough push mowers.
Can a Murray 20 inch blade MNA152701 fit a Hyper Tough mower?
Yes, because several 20-inch Murray and Hyper Tough walk-behind mowers share underlying Daye manufacturing platforms, models carrying the MNA152701 designation use identical 20-inch blades with the 1-inch by 3/4-inch oval center hole pattern.
How do you measure a hyper tough 20 inch lawn mower blade?
Lawn mower blades are measured diagonally from the tip of one cutting edge across to the opposite tip, rather than straight along the flat side. A standard 20-inch blade measures 20 inches along this diagonal line, with a typical blade width of 2-1/4 inches.
How do I know if a hyper tough blade compatible option will work?
To confirm compatibility, inspect your existing mower blade to verify it has an oval center mounting hole measuring 1 inch by 3/4 inch and check your mower deck label for part numbers 2105300125 or 2105300125A.
