EGO Power+ LM2142SP 21-Inch Self-Propelled Lawn Mower vs Greenworks 40V 21-Inch Brushless Self-Propelled Lawn Mower: Full Comparison
I've tested dozens of battery-powered mowers over the years, and the EGO vs Greenworks matchup consistently generates the most questions from readers. These are legitimately two of the best brands in cordless lawn care, but they're built for different types of homeowners.
The EGO Power+ LM2142SP sits at the top of the battery mower market for good reason. That Peak Power technology isn't just marketing—it actually combines output from dual battery ports to deliver 7.5 ft-lbs of torque. That's gas mower territory. I've pushed this thing through overgrown sections of my lawn that would bog down lesser mowers, and it just powers through. The dual 5.0Ah battery setup gives you about 60 minutes of runtime, which translates to roughly half an acre of cutting. EGO also added IPX4 weather resistance and LED headlights, so you can mow in light rain or finish up after sunset.
Greenworks takes a different approach with their 40V model. You're giving up some muscle—5.0 ft-lbs of torque versus EGO's 7.5—but the brushless motor handles regular residential mowing just fine. Where Greenworks really shines is weight. At 63 lbs compared to EGO's 79 lbs, you feel the difference even with self-propulsion engaged. The bigger story is battery compatibility. Greenworks has built out an ecosystem of 75+ tools on the same 40V platform. If you're planning to ditch gas for all your outdoor equipment, that matters.
Lawn size is where you need to be honest with yourself. EGO comfortably handles up to 0.5 acres on those dual batteries. Greenworks works best under 0.35 acres with a single battery. Both give you 21-inch steel decks with comparable height adjustments and mulching options. EGO's 2.5-bushel bag beats Greenworks' 2.0-bushel capacity—not huge, but you'll notice fewer trips to empty on bigger properties.
Build quality leans toward EGO with better weather sealing and heavier construction. Greenworks isn't cheap feeling, just lighter. Both warranties land around 4-5 years, which tells you both companies expect their mowers to last.
The choice really depends on your situation. Need maximum power and runtime for a larger property or thick grass? EGO justifies the extra $200-300. Running a typical suburban lawn under a third of an acre and want to save money while building a compatible tool collection? Greenworks delivers better value.

Frequently Asked Questions
EGO runs longer—up to 60 minutes on dual 5.0Ah batteries compared to Greenworks' 45 minutes on a single 5.0Ah battery. But Greenworks batteries cost less to replace and work with way more tools in their lineup, so there's a trade-off depending on what matters to you.
EGO handles it better thanks to IPX4 weather rating, so you can actually mow in light rain or wet conditions without worry. Greenworks can deal with damp grass but doesn't have the same weather sealing, so I'd stick with EGO if you frequently mow in less-than-ideal conditions.
Depends on your lawn. If you're dealing with more than a third of an acre, thick grass, or tough mowing conditions, that extra $200-300 for EGO makes sense. But for typical suburban lawns under 0.3 acres with regular upkeep? Greenworks gives you plenty of performance and saves you money.
Both offer 4-5 year warranties on mowers and batteries. EGO gets slightly better customer service ratings from what I've seen, but Greenworks has more service centers because they're in more retail chains. So warranty claims might actually be easier with Greenworks depending on where you live.
Only if you're already in that brand's ecosystem. EGO runs on 56V batteries that work with their Power+ tools, while Greenworks uses 40V across their lineup. The batteries don't cross over between brands or with other manufacturers, so you're committing to one system.
It depends on your priorities. The EGO Power+ delivers superior raw power with 7.5 ft-lbs of torque and dual battery runtime that handles demanding mowing jobs better, making it the winner for larger properties or thick grass. However, Greenworks offers solid performance at a lower price point and fits into a massive 75+ tool ecosystem if you're already invested in their platform.
Choose EGO if you have a property over a third of an acre or demanding mowing conditions where power and extended runtime justify the premium price. Go with Greenworks if you want reliable mid-range performance, prefer a lighter machine, and prioritize saving money or expanding a compatible tool collection.
The EGO Power+ outperforms with 7.5 ft-lbs of torque and dual battery support for longer runtimes on bigger jobs, while the Greenworks offers a lighter, more maneuverable design and fits into their extensive 75+ tool ecosystem at a lower cost. EGO targets serious homeowners with demanding properties, while Greenworks appeals to budget-conscious buyers seeking solid middle-ground performance.
