Best Push Button Start Lawn Mowers (2026)

On the LM2114 starting is a two-step action: hold the safety bar against the handle and press the start button, and the brushless motor spools up immediately. Releasing the bar stops the blade, which is the interlock that makes electric mowers so much safer than a gas engine that keeps running. There is nothing to prime and no warm-up.

EGO rates the motor at up to 6.0 ft-lbs of torque and the battery at up to 55 minutes, which is enough for roughly a half-acre of light, dry grass. The 21-inch deck is the widest of the push models in this guide, so you make fewer passes than with the 16-inch Greenworks or KOMASTY. Compared with the self-propelled LM2134SP-2, this is lighter and simpler but you do the pushing.

Because the start is electronic, the common failure points are the bail switch and the battery contacts. Keep the contacts clean and dry, store the pack indoors and sharpen the blade yearly. The same pack runs the brand's other tools, which spreads the cost.

The LM2134SP-2 uses the same button-and-bail start as the LM2114 but adds a Touch Drive handle that senses your palm and drives the wheels at the speed you push. Two batteries power it, which is where the claimed 100 minutes comes from, and the motor is rated up to 7.0 ft-lbs.

Starting is as effortless as it gets, but the machine is heavier than the push version and costs more. If your lawn is flat and under a half-acre, the push LM2114 gets you the same easy start for less. If there is a slope, or hand strength is limited, the extra drive is worth it.

Two packs mean two things to charge and keep indoors, but they also mean a long runtime and the option to swap. Check the bail switch for sticking and the wheel hubs for packed grass after wet mows. Because the two packs are meant to be used together, a weak or mismatched second pack drags the pair down, so replace them as a matched set when one starts to fade.

What stands out here is the combination of a steel deck and a 60V platform that Greenworks says delivers 50% more torque than its 40V mowers, with a blade speed of 3,200 rpm that the maker likens to a 150cc gas engine. The listing also calls out dual self-sharpening blades that adjust power for tall, wet or thick grass.

The IPX4 rating means splash resistance, which tolerates damp grass and light rain but is not a licence to hose the machine down. Compared with the EGO LM2114, the Greenworks has a smaller platform ecosystem but a larger-capacity pack at 5.0Ah, and the steel deck is more rigid than the polymer decks on the lighter Greenworks models.

Starting is by button, so there is no pull cord. Keep the pack indoors, wipe the deck after each cut, and sharpen or replace the blades yearly. The 60V pack fits other Greenworks 60V tools but not the 40V or 80V lines.

Greenworks uses a polymer deck about 35% lighter than steel on this model and pairs it with a push-button start, so the whole machine is built to be easy for someone who finds a heavy mower a chore. It cuts a 16-inch swath and the maker claims up to a third of an acre per charge in the right conditions.

It is the opposite of the 60V model's philosophy: where that one adds torque and a steel deck, this one saves weight. Against the KOMASTY 16-inch, it is the more established brand with a polymer deck, while the KOMASTY includes two packs. A polymer deck can crack on a hard strike, so avoid stones.

The push-button start is simple and reliable, the pack is charged by a standard charger and the 40V battery family covers other Greenworks tools. Store the pack indoors and sharpen the blade each season.

KOMASTY packs two 4.0Ah batteries that power the mower together, a brushless motor reaching up to 3,400 rpm and a 2-in-1 deck that mulches or bags. Starting is by button, and five height positions cover routine cutting.

The dual-pack design is a trade: two small packs give roughly 144 watt-hours total, well below the energy of EGO's larger single pack, but they share a charger and are simple to swap. Compared with the Greenworks 40V, you get a second battery and a mulching deck, but the brand's parts and support record is thinner.

Before buying, check battery availability and warranty length, since a lesser-known brand can be hard to service. Keep the packs indoors, charge them after use and clean the underdeck. For a first cordless mower on a small lawn it is a sensible entry. A good first-week habit is to mow once with a fresh pair and note how many minutes the lawn takes, because that single number tells you whether you will ever need a third pack. If the pair is empty before the last strip, plan for a spare or a shorter weekly interval.

Casince offers a 17-inch deck, a 3000 rpm brushless motor with up to 1200 watts peak and two 20V 4.0Ah packs that the maker says run up to 40 minutes. The 50-liter bag is large, so fewer trips to empty clippings.

It is a straightforward electric start machine, and the extra inch of deck over the 16-inch models helps a little. The peak wattage claim is not a continuous rating, so do not compare it directly with EGO's torque figure. Against the Greenworks 60V, it has a far smaller platform but a lower price of entry and a bag included.

Expect a few good seasons from it rather than a decade of service. Test the start routine when it arrives, keep batteries inside, and watch for how well the parts and battery supply hold up. If it works for you, the packs are standard 20V and not tied to a larger system. The big bag also changes how you mow: a full 50-liter bag is heavy to lift and dump, so empty it a little early rather than letting it overflow, and shake out the mesh so airflow stays strong and the blade keeps lifting grass into it.
