(1 Pack) Replacement Lawn Mower Blades 20" for Oregon 2105300125A - Compatible with MNA152505 MNA152701 Review

Overview

If you own an EGO mower with a 20-inch deck—specifically the MNA152505 or MNA152701 models—you’ve likely discovered that OEM replacement blades can be pricey or hard to find. This $19.99 pack of replacement blades, compatible with Oregon’s 2105300125A design, offers a direct, no-compromise alternative. Designed for homeowners who want a sharp, balanced cut without paying dealer prices, these blades are drop-in replacements that let you keep your EGO mower running like new for seasons to come.

Who Should Buy This

• EGO mower owners with 1/4 to 1/2 acre lots – If you’re mowing a modest lawn and your original blades are dull or chipped, this is an affordable way to restore cut quality without buying a whole new mower or deck assembly.
• Weekend warriors who value convenience – You don’t want to hunt down specialty parts or wait for backordered OEM blades. This pack ships fast and fits common EGO models, so you’re back mowing in minutes.
• Budget-conscious homeowners – At $19.99 for a pair, this is roughly half the cost of some OEM options. If you sharpen your own blades or replace them annually, the savings add up quickly.
• DIYers comfortable with basic maintenance – Swapping blades on an EGO mower is straightforward with a socket wrench. If you can change a tire, you can install these.

Key Features Breakdown

• 20-inch blade length – This is the exact size for EGO’s 20-inch deck models. Using the correct length ensures full cutting coverage and prevents the blade from hitting the deck housing. Too short and you’ll leave uncut strips; too long and you risk damage.
• Compatible with Oregon 2105300125A – Oregon is a trusted aftermarket brand in lawn equipment, known for durable steel and precise balancing. This compatibility means the mounting hole pattern and blade thickness match the original EGO specs exactly.
• Fits MNA152505 and MNA152701 – These are the specific EGO mower models that use this blade. Double-check your mower’s model number before buying—this isn’t a universal fit for all 20-inch EGO mowers.
• Sold as a 1-pack – You get one blade per package. Most EGO mowers use two blades, so you’ll need to order two packs for a full replacement. This is a common point of confusion, so read the listing carefully.
• Steel construction with heat treatment – The blade is hardened for edge retention, meaning it stays sharp through more mowing sessions than cheaper stamped steel. It’s not a premium nitrogen-infused blade, but it’s a solid step up from basic replacements.

Pros

1. Direct drop-in fit – No filing, drilling, or adapters needed. The mounting hole and offset match the original EGO blade perfectly. You’ll have it installed in under 10 minutes.
2. Cuts cleanly – The blade design produces a crisp, even cut on standard turf grasses like fescue, bluegrass, and Bermuda. No ragged edges or torn grass tips.
3. Durable edge – The heat-treated steel holds an edge noticeably longer than the cheapest generic blades. You’ll get a full season of weekly mowing before needing to sharpen.
4. Affordable price point – At $19.99, it’s a solid value compared to OEM blades that can run $30–$40 each. You save money without sacrificing performance.
5. Balanced out of the box – Most users report the blade arrives pre-balanced, meaning less vibration than unbalanced aftermarket blades. Your mower runs smoother, and your deck bearings last longer.
6. Easy to source – Unlike some niche EGO parts, this blade is widely available and ships quickly. No waiting weeks for a backorder.

Cons

1. Only one blade per pack – Since most EGO mowers use two blades, you need to buy two packs for a full replacement. This isn’t obvious from the title, and it can catch buyers off guard.
2. Not for all 20-inch EGO models – Compatibility is limited to the MNA152505 and MNA152701. If you have a different EGO model (like the LM2100 or LM2102SP), this blade won’t fit.
3. No mulch plug or bagging enhancements – This is a standard lift blade. If you want a dedicated mulching or bagging blade, you’ll need to look for a specialized design. It works fine for side-discharge and basic bagging, but it’s not optimized for fine mulching.
4. Edge retention could be better – While good for the price, the steel isn’t as hard as premium options from brands like MaxPower or Stens. If you mow sandy soil or hit rocks often, you’ll need to sharpen more frequently.

Bottom Line

If you own an EGO MNA152505 or MNA152701 mower and need a reliable, affordable blade replacement, this pack is a smart buy. It delivers a clean cut, installs without hassle, and costs significantly less than OEM parts. Just remember to order two packs if your mower uses dual blades, and confirm your model number before purchasing. For the price, it’s the best value in aftermarket EGO blades right now—especially for casual users who sharpen once a season and want to keep their mower running strong without overspending.

Frequently Asked Questions

Q: Will this blade fit my EGO LM2100 mower?
A: No. This blade is specifically designed for the MNA152505 and MNA152701 models. The LM2100 uses a different blade pattern and length. Always check your mower’s model number before ordering.

Q: Do I need to buy two packs for a single mower?
A: Yes, if your EGO mower has a 20-inch deck with two blades. Each pack contains one blade, so you’ll need two packs for a complete replacement. Some older single-blade 20-inch models exist, but the MNA152505 and MNA152701 are dual-blade designs.

Q: Is this blade pre-sharpened?
A: Yes, the blade comes with a factory edge that’s ready to use. No additional sharpening is needed before installation. However, for the best cut, you may want to lightly hone the edge with a file if you prefer an ultra-sharp finish.
