Mowers
Best battery push mower
The lightest published weight, the lowest published draw, and a rating that tells you exactly where to stop. Less machine, done deliberately.

Push mowers are treated as the entry-level option, which undersells them. On the published figures, a push deck is the most efficient machine in the whole category, and on the right lawn it is not a compromise at all — it is the correct purchase.
The short answer
The efficiency case, worked out
Efficiency in this category is mostly an absence of features. One less inch of deck, no drive motor, and 17.5 lb less to move. That is the entire mechanism, and the payoff is that a 160Wh pack does what a 320Wh pack does on the heavier machine.
The pick: Greenworks LM2054
| Spec | Published figure | Why it matters |
|---|---|---|
| Weight | 57.5 lb | The lightest published mower weight in our registry |
| Deck | 20 in, 4-in-1 | Mulch, bag, side discharge and leaf pickup on one blade |
| Blade speed | 3200 RPM | The same figure as the 80V flagship |
| Battery | 40V 4.0Ah = 160Wh | The smallest pack of any mower here |
| Runtime | Up to 40 min | About 4.0 watt-hours a minute |
| Cut height | 1.2-3.6 in, 7 positions | Reaches 3 in, but with little headroom above it |
| Acreage | Up to 1/3 acre | One of only two published mower acreage ratings we hold |
| Recharge | 120 min | Three times the 80V machine's 40 minutes |
| Warranty | 3-yr tool / 3-yr battery | Shorter than the 80V line's four years |

The one specification to check before you buy
University of Minnesota Extension recommends maintaining a typical residential lawn at three inches or higher, mowing before the grass reaches 4.5 inches, and removing no more than one third of the leaf tissue per cut. A 3.6 inch ceiling satisfies that, but only just.
If you want to mow higher than that — in shade, in drought, or on a lawn that is struggling — the EGO LM2135SP publishes 1 to 4 inches over eight positions and gives you the room. Full detail in the mowing height guide.

Who should buy a push mower
- Flat lawns up to about a third of an acre. That is the published rating and it is a fair one.
- Anyone lifting the mower. 57.5 lb onto a shelf or into a car is a different proposition from 75 lb.
- Small storage. A 20 inch deck is a foot narrower than nothing, but on a crowded garage wall an inch is an inch.
- Anyone who wants the smallest pack that finishes the job. 160Wh is the cheapest energy to replace when the battery eventually goes.
Who should not
- Lawns with any real slope. Extension safety guidance is to mow across a slope, and doing that with 57.5 lb unassisted is work.
- Anything past a third of an acre. The rating exists for a reason.
- Thick or overgrown growth, where a bigger deck and more torque genuinely help.
What we cannot tell you
We have not pushed it. How the 4-in-1 deck handles wet clippings, how hard 57.5 lb feels after 40 minutes, and whether the 40-minute claim survives a first spring cut are all outside what Greenworks publishes.
What is published and decisive: 57.5 lb, 4.0 watt-hours a minute, a third of an acre, and a 3.6 inch cut-height ceiling that you should check against your own lawn before anything else.

40 minutes on a 160Wh pack and 57.5 lb to push -- the honest answer for a third of an acre and nothing more.

40V x 4.0Ah = 160Wh. Note it claims 40 minutes on 160Wh where the 80V flagship claims 33 minutes on 320Wh -- a 20 in deck and no self-propel drive motor is why.
What the numbers favor
- Lightest published weight on this page at 57.5 lb, and the only sub-60 lb mower here
- Claims 40 minutes from 160Wh -- the best published minutes-per-watt-hour of any mower on this page
- Same 3200 RPM blade speed as the 80V flagship
- 4-in-1 deck at the entry price
What they don't
- Push only -- no drive assist on any slope
- 1.2 in minimum cut height is lower than most cool-season lawns should ever be cut
- 120-minute recharge, three times the 80V model's 40 minutes
your lawn is over a third of an acre or has any real slope. Greenworks rates it to 1/3 acre and you will be pushing all 57.5 lb of it up the hill yourself.

56V x 7.5Ah = 420Wh, using EGO's advertised pack voltage.
What the numbers favor
- 420Wh in the box -- the largest included pack of any flagship walk-behind on this page
- Eight cut-height positions from 1 to 4 in, the widest published range here
- Three interchangeable lower blades (mulching, high-lift bagging, extended runtime)
- 5-year tool warranty, the longest published on this page
What they don't
- EGO publishes torque (7.0 ft-lbs), not motor wattage, so it cannot be compared directly against Greenworks' 1500W figure
- The 7.5Ah pack that earns the runtime claim is also the expensive one to replace
your yard is under a quarter acre. You would be paying for 420Wh of headroom you will never discharge, and a 20 in push mower cuts the same grass.
