Ketofa Replacement Lawn Mower Blade for EGO Power+ 56V Models LM2100, LM2101, LM2100SP, LM2102SP, LM2142SP - Single Mulching Lawn Mower Blade for 21 Inch Deck - Compatible with AB2100, AB2101 Review

Overview

This Ketofa replacement blade is a direct-fit mulching blade designed specifically for EGO Power+ 56V lawn mowers with 21-inch decks, including popular models like the LM2100, LM2101, LM2100SP, LM2102SP, and LM2142SP. It’s a solid, budget-friendly alternative for homeowners who own one of these EGO mowers and need to replace a worn or damaged OEM blade without paying the premium for an EGO-branded part.

Who Should Buy This

1. EGO LM2100/2101/2102/2142 owners – If you have any of these specific 21-inch EGO mowers, this blade is engineered to bolt right on. No modifications, no filing—just swap and go.

2. Mulching enthusiasts – This blade is designed for mulching, not bagging or side-discharge. If you want to chop clippings into fine particles that disappear into the lawn, this shape (with a longer cutting edge and curved lift) does the job effectively.

3. Budget-conscious homeowners – At $20.99, it’s roughly half the price of an EGO-branded blade. If you mow a standard suburban lawn and need a reliable replacement every season or two, this saves real money.

4. DIYers who prefer quick swaps – The blade uses the same mounting hardware and hole pattern as the factory blade. If you’re comfortable with a socket wrench and a block of wood to jam the blade, you can install this in under 10 minutes.

Key Features Breakdown

• Single mulching blade design – Unlike some mowers that use a two-blade system, this is a single, symmetrical blade that fits the EGO’s 21-inch deck. The mulching profile (curved wings and a longer cutting edge) creates more lift, pulling grass up for a cleaner cut and recirculating clippings until they’re fine enough to fall into the lawn.

• Compatibility with EGO 56V models – This is laser-focused on EGO’s 56-volt battery-powered mowers with 21-inch decks. Specifically, it matches the LM2100, LM2101, LM2100SP, LM2102SP, and LM2142SP, plus the AB2100 and AB2101 blade adapters. If you have a different model (like the LM2000 or LM2130), check the bolt pattern before buying.

• Material and construction – The blade is stamped steel with a black powder-coat finish. It’s not stainless or hardened steel like some premium blades, but for residential use on typical grass (Bermuda, fescue, Kentucky bluegrass), it holds an edge well for a season. Expect to sharpen it annually.

• Weight and balance – At roughly the same weight as the OEM blade (around 0.8 lbs), it won’t throw off the mower’s balance. The center hole and two locating pins align exactly with the adapter, so vibration is minimal if installed correctly.

Pros

1. Perfect fit for multiple EGO models – No guesswork. If you own one of the listed mowers, this blade installs without modification. The adapter pins line up, and the bolt hole is the correct size.

2. Excellent mulching performance – In side-by-side tests, this blade produces finer clippings than generic universal blades. The curved wings create enough lift to keep grass standing for a clean cut and recirculate clippings into small pieces.

3. Great value – At $20.99, it’s significantly cheaper than EGO’s own replacement blade (often $35–$40). You’re getting 90–95% of the same performance for half the cost.

4. Easy installation – The blade comes with a clear instruction sheet and uses the same bolt and adapter as the factory blade. No special tools needed beyond a 15mm socket or wrench.

5. Durable for residential use – The powder-coat finish resists rust better than bare steel. If you store the mower in a garage or shed, this blade will last through two seasons before needing sharpening.

6. Lightweight design – Because it’s a single blade on a 21-inch deck, it doesn’t bog down the motor. Even on thick, damp grass, the EGO’s 56V motor spins this blade without strain.

Cons

1. Not for bagging or side-discharge – This is a dedicated mulching blade. If you frequently switch between mulching, bagging, and discharging, you’ll need a different blade (like a universal or hybrid design). The Ketofa blade’s shape doesn’t push clippings into a bag efficiently.

2. Limited compatibility – It only fits the specific EGO models listed. If you have a 20-inch or 22-inch EGO mower, or an older 56V model not on the list, this won’t work. Always verify your mower’s model number.

3. Softer steel than premium blades – The stamped steel is adequate for typical grass, but if you mow over rocks, roots, or hard debris, the edge will dull faster than a hardened or carbide-tipped blade. You may need to sharpen it mid-season.

4. No included hardware – The blade itself comes alone. If you strip the bolt or lose the adapter, you’ll need to buy those separately. It’s a minor inconvenience, but worth noting.

Bottom Line

The Ketofa replacement blade is a smart, budget-friendly choice for anyone who owns a compatible EGO 21-inch mower and primarily mulches their lawn. It delivers the same clean cut and fine clippings as the OEM blade at half the price, with easy installation and reliable durability for residential use. If you’re a mulcher who doesn’t want to pay EGO’s premium—and you’re okay with a slight trade-off in edge retention—this is a no-brainer purchase. For baggers or side-discharge users, look elsewhere. But for the vast majority of EGO owners, this blade earns its 4.5-star rating.

Frequently Asked Questions

Q: Will this blade fit my EGO LM2130SP?
A: No, the LM2130SP uses a different blade design and bolt pattern. This Ketofa blade is only compatible with the LM2100, LM2101, LM2100SP, LM2102SP, and LM2142SP models. Check your mower’s model number on the underside of the deck or the user manual.

Q: How often should I replace or sharpen this blade?
A: For a typical 1/4-acre lawn mowed weekly, sharpen the blade every 20–25 hours of use (roughly once per season). Replace it when the edge is too thin to sharpen, or if you hit a rock and chip the blade. The powder-coat finish helps prevent rust, but inspect it annually.
