EGO Power+ LM2135SP Review
The Cordless Mower That Actually Replaces Gas
The EGO POWER+ LM2135SP is a 21 inch self-propelled cordless mower rated for 60 minutes on its 56V 7.5Ah battery. Owners cover up to half an acre on a charge, and it is the one battery mower they stop comparing to gas.
The verdict
EGO sells more than a dozen cordless mowers and the LM2135SP sits in an awkward spot. Costing over a thousand dollars in this two battery bundle, it is far from the cheapest way into battery mowing. What you get for that is the mower owners stop apologizing for.
Rated 4.7 stars from 727 reviews and carrying Amazon’s number one Top Rated badge in cordless mowers, the LM2135SP has the highest rating of any battery mower we looked at. More useful than the rating is what the reviews actually say, because they are unusually specific about yard sizes and timings.
Runtime in the real world
EGO claims up to 60 minutes with the included 56V 7.5Ah battery. Owner reports line up with that figure, which is rarer in this category than you might expect.
One verified owner covers 9,000 sq ft without recharging. Another, Becky, mows half an acre and needs two batteries, taking about 75 minutes in total. A third owner with a third of an acre on a sloped lot got through the whole front yard and half the back on the smaller 5.0Ah battery alone.
Two things shorten that figure, and both come up repeatedly. Wet or long grass costs you runtime, and so does leaning on the self-propel. Becky uses the drive constantly and accepts the hit. Ike only engages it going uphill and reports the mower is light enough to push the rest of the time.
The Select Cut blade system
Three lower blades come in the box, and they are the main reason to pick this model over a cheaper EGO. A mulching blade arrives fitted and suits weekly cutting. A high lift bagging blade adds suction when you want a clean finish with nothing left on the lawn. An extended runtime blade trades a little cut quality for more minutes per charge.
An upper blade works alongside whichever lower blade you fit, slicing clippings finer. One owner describes the cut as close to or on par with gas mowers at the same price, with the honest caveat that it can leave the occasional straggler that does not get lifted on the first pass.
What owners complain about
Three things come up often enough to mention. The self-propel does not always engage on the first press, which one owner calls nit-picky and another finds mildly irritating. Blade life is about a season before uneven cutting shows up. And the side discharge chute clogs, which is a pattern across the whole EGO line rather than a fault with this model.
A useful tip from an owner called Steffi: empty the grass catcher at around two thirds full rather than waiting for it to fill, because a packed bag makes the motor work harder and costs you battery. She also recommends spraying the underside of the deck with silicone before the first use and every five or six cuts after that, which keeps clippings from building up.
Who should buy it
Owners with a quarter to half an acre get the most out of the LM2135SP. At that size the self-propel earns its keep, the 7.5Ah battery gets you through in one or two goes, and the 21 inch deck means fewer passes.
Under about 5,000 sq ft the maths falls apart. The EGO LM2114 cuts the same 21 inch width, costs $449.00, and will finish a small yard on one charge. Most owners of the push version report it is light enough that self-propel never gets missed.
Worth knowing before you commit: the battery fits every tool on the EGO 56V platform, and several owners mention running a string trimmer and leaf blower off the same pack after mowing. If you plan to build out a cordless set, that changes the value calculation.

Questions people ask
How long does the EGO LM2135SP battery last?
EGO rates the included 56V 7.5Ah battery at up to 60 minutes. Owners back that up. One reports covering 9,000 sq ft without recharging, and another takes 75 minutes to do half an acre using two batteries. Expect less in wet or long grass.
Is the EGO LM2135SP worth the extra money over the LM2114?
Only if you need the self-propel or the extra blades. Both cut 21 inches. The LM2135SP adds 8 cutting heights instead of 7, one more foot-pound of torque, a faster charger and the Select Cut blade system, for roughly double the price.
Does the LM2135SP come with a battery and charger?
Yes. The kit includes a 56V 7.5Ah battery and the Rapid Charger, and this bundle adds a second 5.0Ah battery that ships separately.
Can the EGO LM2135SP handle a half acre lawn?
Yes, though owners with half an acre use two batteries. One owner mows half an acre in about 75 minutes and swaps to a second battery partway through.
How often do the blades need sharpening?
One owner noticed uneven cutting by the end of a single season and needed to sharpen. A dull blade also drains the battery faster, so treat uneven cuts as your prompt to sharpen.
