Best Overall
EGO Power+ 21-Inch Cordless Self-Propelled Mower LM2134SP-2
Our verdict: A full-size cordless mower with self-propelled drive on a broad battery platform.
EGO's LM2134SP-2 is the mower to buy when the lawn is bigger than a postage stamp and you refuse to haul gas. It pairs a 21 inch deck with self-propelled drive on the company's cordless battery platform. That drive matters because it matches wheel speed to your walking pace, so the pushing effort that tires you on a slope or a long afternoon mostly disappears.
It ranks first because it is the only pick that combines full deck width, drive assist and zero fuel in the $500 and up tier. The Greenworks 80V matches that format for less, but EGO's platform is the more established of the two and shares batteries with other tools from the same maker.
Medium to large lawns, with any slope at all, reward it most. The caveat is cost and weight: it is the priciest cordless here and heavier than the push models, so skip it for a small flat yard.
