Best Cordless Lawn Mowers (2026)

The LM2114 is built around a brushless motor that EGO rates at up to 6.0 ft-lbs of cutting torque, and the useful part of that claim is the sustained load behaviour: the motor holds blade speed when the deck bogs down in thick turf instead of sagging the way brushed cordless motors do. The 21-inch deck is the standard full-size width, so you take fewer passes than any of the 17-inch machines in this lineup, and the seven height positions starting at 1.25 inches cover scalping a dormant lawn up to leaving cool-season grass tall in summer.

The tradeoff is that this is a push model. On a flat half-acre that is fine, but on a slope you do the work, and the self-propelled sibling from the same family costs more and drains the same pack faster. Against the Greenworks 80V in this guide, the EGO gives up rear-wheel drive but wins on platform breadth, because the same 56V pack runs the brand's trimmers, blowers and chainsaws, which makes the pack feel cheaper over a few seasons.

In year three the things that matter are blade condition and battery habits. Sharpen or replace the blade once a season, because a dull edge tears grass and pulls more current from the pack. Hose the underdeck gently, never spray into the motor housing, and keep the pack indoors in a garage that gets very hot or below freezing. The deck stores upright, which saves floor space in a shed.

Greenworks puts a brushless motor and a rear-wheel-drive transmission under a 21-inch deck here, and the variable-speed control is what separates it from cheaper self-propelled models that only run at one pace. Rear drive is the right layout for a mower, because as you lean on the handle or the bag fills, weight shifts back over the driven wheels and traction improves rather than disappears. That is why it climbs a damp slope better than a front-drive machine would.

The cost is runtime. An 80V max pack is roughly 72V nominal, and at 4.0Ah that is about 288 watt-hours, but the drive system draws from the same pack, so the claimed half-acre figure applies to light dry grass on flat ground. Compared with the EGO LM2114, you trade a longer-lasting push machine for one that does the walking, which suits sore knees and sloped lawns better than it suits maximum acreage.

Ownership is simple but pay attention to the drive cable and wheel gear covers: pull grass and mud out of the rear wheel hubs after wet cuts so the pawls do not clog. The LED headlight is a small bonus for dusk mowing. Remember the 80V pack fits Greenworks 80V tools only, and not the 60V or 40V lines.

Worx splits the energy across two 20V packs that work together as a 40V system, which means about 144 watt-hours in total by the nominal-voltage math, well under the single big packs of the EGO or Greenworks 80V. The payoff is that the same 20V packs also run Worx's wider tool range, so one owner can feed a drill, a trimmer and the mower from a shared pool of batteries.

The 17-inch deck is a clear step narrower than the 21-inch machines, so a quarter-acre lot is about the sweet spot. Its two modes matter: mulching returns fine clippings to the lawn if you mow often and take no more than a third of the blade height, while the rear bag is the better choice when grass has grown long and clippings would clump. Against the Casince in this guide, the Worx is the more established brand with a more mature accessory ecosystem, but the Casince brings a larger bag.

Upkeep is the same as any brushless mower: clear the underdeck after each cut, store the packs out of heat and cold, and replace the blade yearly. Because it runs two smaller packs, you can swap one in and keep cutting while the other charges only if you own spares, so budget for a third pack if your yard pushes the limit.

This model swaps the usual steel deck for a molded poly one, which Greenworks puts at about 40% lighter than steel. That saves strain when you lift the front to turn at a fence line or carry the mower down a step, and polymer cannot rust where grass clippings stay wet. The dual-port packs deliver a 48V system, and the stated runtime of up to 45 minutes is the figure for light conditions.

Because the deck is lighter and narrower than the 21-inch machines it handles like a larger string trimmer on wheels, and that makes it a good match for lawns with many beds and obstacles. The tradeoff is rigidity: a poly deck flexes more than steel if you run it over rocks or roots, so it fits manicured grass better than a lot with stumps. The five height steps from 1-3/8 to 3-3/4 inches cover most needs.

In ownership, a poly deck does not need paint touch-ups and cleans with a hose, but it can crack if you strike a hard obstacle, so check the lip near the blade before each season. Because the 24V packs are part of a Greenworks line, they also fit other 24V tools, so a trimmer purchase later does not require new batteries.

Casince leans on volume here: a brushless motor rated at 3000 rpm with up to 1200 watts peak, two 20V 4.0Ah packs and a 50-liter bag in the same kit. The 1200W figure is a maximum, not a continuous rating, and the six height positions from 1 to 3 inches top out lower than the EGO, so it suits regularly maintained turf more than overgrown lots.

Set next to the Worx WG745, the Casince gives the same 17-inch width and similar pack arithmetic, at 144 watt-hours total, but with a larger collection bag that means fewer trips to dump clippings. What you give up is the long-term support of an established brand: battery replacements and blade parts take more effort to source than a Greenworks or EGO part.

Plan on replacing it sooner than a name-brand machine. Sharpen the blade early in the season, test the pack-swap routine before the grass grows, and store the batteries indoors. If you outgrow it, the packs are standard 20V form and do not lock you into a larger platform, so the downside of trying it is lower than with an 80V pack system.
