EGO Power+ 21-inch LM2100: Design and build
- 74lb with one 7.5Ah battery
- 56 volt system
- 21-inch cut area
The EGO Power+ 21-inch LM2102 is a solid IPX4 construction meaning you get proper waterproofing so this beast will live quite happily out in your garage. You also get LED headlights built in so you can mow anytime you feel the need without worry about lack of visibility.
The mower runs off a 56V lithium-ion battery which is part of the EGO Power+ ARC Lithium series. That means it's interchangeable with other EGO devices like blowers and trimmers, for example. So you may only need to buy one battery if you're investing in lot of these. Or, you may have a spare for continued use even when this runs down.
Despite having a decent 21-inch cut area, the whole mower folds down for compact storage. You also get a 2-bushel grass collection bag which is easy access for emptying and reattaching. The handlebar has three position levels so you can find the most comfy for you, making it ideal even for continued use.
All that is covered by an impressive five year parts warranty and a three year battery warranty.
EGO Power+ 21-inch LM2100: Features
- Fast charging
- 3-in-1 function for waste
The EGO Power+ 21-inch LM2100 has a stand-out feature and that's the fact that it offers more torque than some gas mowers, despite running on battery. And that battery is another feature worth mentioning as it can be charged to full in under an hour. Then you should get up to an hour's worth of runtime - that's better than the likes of the Ryobi 40V 21-inch Brushless Smart Trek but not as good as the Greenworks 21-inch 60V MO60L410.
For grass, you've got three options of using the bagging system, mulching or using the side discharge. Either way you can use the three different handle positions to find comfort and vary the mower cutting height between one and a half inches and four inches high.
You get a push button start for super simple running and the LED headlights help you see no matter what time of day you're out working on the lawn. Since this runs really quietly, thanks to that battery, you should be good to mow after dark without bothering the neighbors.
EGO Power+ 21-inch LM2100: Performance
- Lots of power
- Light enough to move easily
- Decent notifications
The EGO Power+ 21-inch LM2100 offers lots of power through that electric motor. The result is that you can use this for pretty much any lawn job you want to tackle with it aimed at up to a half acre. In reality, of course, you might not cover that much space if the job is the first cut of the season when grass is long and tough. This is because it will chew through the battery faster.
Realistically, with the larger 7.5Ah battery, you're looking at about 45 minutes for an average difficulty lawn cut. You might get more out of it but, if it's wet, that might be tougher and you'll get a little less. Either way you've got light notifications so you can see how much power you have left so it's not really an issue. Having a second battery is the ideal situation so then you don't have to wait for a charge. Even at an hour to full again it's still a hassle if you get stuck.
The 21-inch blade is plenty wide and does make cutting fast work. This model needs you to push but there is a self-propelled variant that you might want to consider if you have a lots of uphill parts to your yard. But once again you'll have to keep in mind that'll eat a bit more battery.
Emptying the bag, folding the mower and moving it about are all very easy, making this a great model for anyone to use.
With quiet running, up to 30 percent less than gas, makes this great for late night cuts or for anyone that just hates that loud noise.
Should I buy the EGO Power+ 21-inch LM2100?
If you’re tired of the noise and hassle of a gas lawn mower, or you’re worried about the risk of having cables cluttering up the lawn during mowing, the EGO Power+ 21-inch LM2100 is the ideal solution. Plus, it’s quieter, cleaner, and better for the environment.
This battery-powered mower offers the same power and performance as a gas mower, without racking up running and service costs. The battery can be swapped across to other EGO Power+ battery devices too, saving you more money and space. And with a 5-year residential guarantee to back up your mower, you’ll have peace of mind too.
