KOFINAM 20-inch Replacement Lawn Mower Blades 2-Pack — Direct-Fit for Oregon 2105300125A, OEM-Style Cut

KOFINAM 20" replacement mower blades (2-pack) are designed to swap in for Oregon part 2105300125A and compatible numbers MNA152505 and MNA152701, delivering a reliable, OEM-fit cutting edge for many walk-behind mowers.

If your mower needs fresh blades, these two 20-inch KOFINAM blades offer direct-fit dimensions and mounting compatibility with several popular OEM reference numbers. They’re sold as a pair for changing both sides or keeping a spare on hand, made to restore cutting performance and evenness without the premium price of branded originals. Check your mower’s part number before ordering to confirm fit, and note these are aftermarket replacement blades, not original equipment from Hyper Tough or Oregon.

How do these blades match the original Oregon part?

These KOFINAM blades are manufactured to the same 20" length and mounting profile as Oregon 2105300125A so they install with the same fasteners and orientation. They’re intended to be compatible with models that list MNA152505, MNA152701, or MNA152516.

• Blade length: 20 inches to match standard OEM sizing.
• Mounting hole pattern mirrors the Oregon reference part.
• Sold as a two-blade set so you can replace both or keep a backup.
• Aftermarket manufacturing—verify your mower’s original part before purchase.

What performance can I expect from these replacement blades?

Expect a crisp, even cut when the blades are new and properly balanced. Because they are aftermarket replacements designed for direct fit, they restore the mower’s original cutting geometry and help maintain turf appearance when installed and sharpened as needed.

• Sharp factory edge for efficient grass shearing.
• Balanced construction to minimize vibration and uneven cuts.
• Durable steel suitable for typical residential lawn use.
• Replace in matched pairs for best cutting results.

How do I install and maintain these KOFINAM blades safely?

Installation follows the same steps as any standard blade replacement: disconnect spark, tip the mower to a safe angle, remove the blade bolt, swap blades, and torque to the manufacturer’s specification. Regular maintenance—inspection, sharpening, and balancing—keeps performance high and extends blade life.

• Always disconnect spark plug before working on the mower.
• Use correct wrench and torque for the blade bolt per mower manual.
• Inspect blades for bends, cracks, or damage before mounting.
• Sharpen and balance blades periodically for clean cutting.
