Compare Electric Lawn Mowers: Cordless

Cordless electric mowers run on rechargeable batteries, with no gas, no cords, and no pull-start hassle — the trade-off is runtime and price.

Comparing electric lawn mowers that are cordless comes down to five numbers: deck width, voltage, runtime, weight, and price. Here’s what actually separates them.

What The Top Cordless Models Offer

The most-cited cordless mowers in current reviews cover a wide price and power range. The EGO Power+ LM2135SP is a 56V, 21-inch self-propelled model with roughly 60–70 minutes of runtime, listing between $550 and $700. Consumer Reports and Wirecutter both name it a top pick.

Budget shoppers have two solid routes. The Greenworks MO40B410 is a 40V, 17-inch push mower at about $200–$250, ideal for small flat yards. The Ryobi RY401180 runs $380–$450, steps up to a 20-inch deck, and adds self-propulsion — a meaningful upgrade if your yard has any slope.

Other models worth knowing: the WORX WG779 is a compact option for tight spaces, the LawnMaster CLMF2434G is light with two 4Ah batteries and a rear roller, and heavier-duty names like ECHO, Makita, Milwaukee, and Stihl all field capable cordless decks for larger properties.

Deck Size: Match The Mower To Your Lawn

Deck width is the first number to check because it sets how long each pass takes. Small yards generally fit 14–16-inch decks, while a 21-inch self-propelled mower suits a quarter acre or more.

• Under 2,000 sq ft: 14–17-inch decks, push models are fine
• 2,000–5,000 sq ft: 17–20-inch decks, push or self-propelled
• Over 5,000 sq ft: 20–21-inch self-propelled decks, carry a spare battery

A push mower on a hilly or large yard is the most common mistake buyers make. Self-propelled models cost more but save real effort on slopes and long runs.

Battery Voltage And Ecosystem Matter More Than You Think

Battery systems are brand-specific. The voltage (40V vs 56V) roughly tracks cutting power, but the bigger question is what else you already own. If you have a Greenworks trimmer, a Greenworks mower lets you share batteries; a Ryobi mower won’t. Buying into one brand’s platform lets you swap batteries among mower, trimmer, and blower — but only within that brand.

Check whether the listing includes a battery and charger at all. Some cordless mower listings are tool-only, which changes the real cost significantly. For bigger lawns, buyer guides consistently recommend keeping a spare battery on hand because runtime drops with thick, tall, or wet grass, and self-propulsion draws extra power.

Runtime claims vary widely by test conditions. Advertised minutes are a ceiling, not a guarantee — treat them as a rough estimate and plan for less on tough cuts.

Which Cordless Mower Should You Buy?

The right pick depends on your yard and your wallet. For a quarter acre or more, the EGO Power+ LM2135SP’s 21-inch self-propelled deck and 56V power justify the price — it’s the clear top choice in current reviews. For smaller lots, the Greenworks MO40B410 at roughly $200 cuts the cost in half while covering the basics.

Before you buy, confirm the battery platform matches tools you already own, verify the kit includes a charger, and size the deck to your actual lawn. If you’re shopping on a tighter budget, our roundup of low-cost electric mowers tests the cheapest models that still cut cleanly. The EGO’s 56V system means future batteries cost more, but the same battery also runs EGO’s trimmers and blowers.

If you can stretch the budget, it’s the mower that will likely outlast your current yard.
