EGO's 21 inch 56V self propelled mower stands out for easy handling, quiet button start operation, and strong cut quality, with Touch Drive making larger yards and slight inclines easier. The two 4Ah batteries and rapid charger add real value, and the batteries are enough for many residential lawns, with some reports of half acre or more on a charge. The main cautions are weight, around 71 pounds with batteries, and battery runtime dropping faster in thick grass or when using self propel. It feels like a solid cordless setup if convenience matters more than gas mower lightness.

  • EGO tool owners building a battery ecosystem, because the included 4Ah packs are useful across blowers, trimmers, and other compatible tools.

  • Homeowners with larger yards or slight inclines, because the self-propelled drive and 56V power make mowing easier and the included batteries cover most residential lawns.

  • People maintaining a half-acre lawn, because two 4Ah batteries are described as enough runtime and the charger alone is valued highly.

  • Buyers wanting a quieter, low-maintenance cordless mower, because it starts with a button, skips fuel and oil changes, and runs noticeably quieter than gas.

  • People expecting a lightweight mower, because this unit weighs about 71 pounds with batteries and feels heavier than expected.

  • Owners of thick Bermuda or other heavy grass on large yards, because two 4Ah batteries can drain quickly and overheat under sustained load.

  • Lawns around one acre or more, because the included batteries are questioned as insufficient for that amount of mowing.

  • Buyers who want long battery life without swapping, because battery runtime can drop after a few seasons and may not finish even a front yard.

Hot take: the LM2135SP at $449 may actually be the better buy.

The LM2122SP-2 at $399 was a killer deal, but for just $50 more the LM2135SP adds the Select Cut dual-blade system, which is one of EGO's biggest upgrades for cut quality and mulching performance.

For those of us with smaller yards and already invested in EGO batteries, I'd rather spend the extra $50 and get the better mower.

Just my 2 cents after spending way too much time comparing EGO models today.

Quote from FuschiaCircle8833 View quoted comment :
I have an 80V dual port Greenworks mower, and it uses the batteries one after another, not at the same time. So I think this is not true for all dual port mowers.
This.
I also have a Greenworks dual port [specifically, a Greenworks 60V 21" Brushless (Self-Propelled) Cordless Lawn Mower, 2 x 4.0Ah Batteries, with dual port charger as well]; mine also uses the batteries sequentially. When one is depleted, the mower switches over to the next one...it's brief & barely noticeable. It's specs say i's 65 lbs, but it seems and handles as if it's much lighter (I have not weighed it).
I cut ~3/4 acre with it, and usually don't even use the self-propel [which was not the case with my old 4-cycle ICE that started to burn oil :-( ].
I usually need to recharge after 1 1/2 hrs., but that gives me a chance to recharge myself and then go back out to finish up :-)
We're on our 2nd season...also used it for mulching leaves last fall. Loving it so far, knocking on wood!

For $50 more, I went with the 800 series with Select Cut blades and a 7.5Ah battery and fast charger.

The deal is dead and what's funny is that the price history doesn't even mention the reduced price from earlier today. I noticed the same thing happen with a TV from Amazon.
still alive here.. tempted to get it just for the 2x 4Ah batteries. Those are the only batteries I don't have, just right for blowers and trimmers, 5Ah is just a bit heavy.

Is this a great deal?
I've been semi pro using these but tried to stretch out the batteries with a gas mower and make my ego 7.5Ah mower last longer.. tempted to get this just for backup. I already have 8 batteries but some are probably 4yrs old!


slow shipping 7% CB will help and I have time to think about it... I'm running an old 25yo Honda commercial on rough field. I'll sell some of my other Ego tools with older batteries. I have a chainsaw I never use,
Prime mixes up reviews and images.. I says 65min on two batteries but only uses one at a time I think.

I should post this EGO POWER+ Portable Inverter, 180W, Power Inverter Generator also on sale. This is the older model I bought before or I'd jump on it. Works great with all Ego batteries https://www.amazon.com/EGO-PAD180...NWBJ/?th=1

Quote from coolguy_dude View quoted comment :
Dual-port mowers draw power from both batteries simultaneously to hit their maximum torque rating. If you put a single battery in it, the cutting torque drops significantly. Running two small 4.0 Ah batteries simultaneously forces each battery to drain rapidly under a heavy load (especially through thick Southern grass like Bermuda). This rapid power draw generates intense internal heat. Forums consistently show that 4.0 Ah batteries run harder and hot-flash (overheat) much faster when trying to push a heavy 21-inch mower deck through a large yard.
I don't believe this model is a dual port. Please don't confuse the two. Here is video https://youtu.be/xcMsQgNOZuw?

Popping in and out! Just snagged it. Had a 250 gift card, so only spent 180 out of pocket.

Is anyone else seeing this come up at $749? I'm not seeing the $399 price.

Ya snooze, ya lose.

I had this in my cart. Talked my wife into it being a good deal, came back to buy and... it's gone.

There's an AmEx points coupon for $40 off that I was going to use. Select card members. https://slickdeals.net/f/19553736-amazon-select-amex-card-members-pay-w-rewards-spend-minimum-of-1-429-points-and-get-30-off-max-30-or-varying-offer?src=SiteSearch

Keep trying folks, it's like a free mower with purchase of two batteries https://www.amazon.com/EGO-POWER-...XZ99/?th=1 $217ea!

It's says temporarily out of stock and no price now so something is up and Prime Day is through FRIDAY .. I just hope the mods don't mark this dead prematurely

Tempted. Will two batteries handle 1 acre?
Why would you want to mow 1 acre yard with a small mower? You need a riding mower, unless you need heavy exercise.
