Best 40V Lawn Mowers (2026)

This Greenworks is the only mower here that combines a 21 inch steel deck with a self-propelled variable-speed drive, so the motor helps turn the wheels instead of you pushing. Rear-wheel drive is the better layout on slopes, because it puts traction under the weight of the grass bag. A brushless motor gives more torque, quieter running and longer life.

Its four modes cover mulching, bagging, side discharge and a turbo leaf pickup. A 5.0Ah battery is the largest in the group, and an LED headlight lets you mow at dusk. Against the 17 inch Greenworks push model, it adds width and drive but also weight.

Blade care, deck cleaning and a charged battery are the main chores. Wash the deck after use, sharpen the blade each season and store the battery inside. It suits half-acre lawns with slopes.

The WORX WG745 runs on two 20V 4.0Ah batteries, a different layout from the single 40V packs on the Greenworks mowers. It weighs only 40 pounds assembled, which is easy to push and lift into a trunk. Intellicut technology senses load and adjusts blade speed, stretching runtime on thin grass and boosting power in thick patches.

A slim deck lets you cut closer to fences and beds, and a battery charge indicator and collapsible handles help day-to-day use. It cuts up to a quarter acre on one charge, a stated figure.

It includes two batteries and a charger, so the kit is complete. Wash the deck, sharpen the blade and keep the packs inside. It suits small to mid yards.

The SKIL is the best-equipped mid-size push mower here: a 20 inch deck, a 6.0Ah battery that is larger than the 5.0Ah on the Greenworks, and an IPX4 rating that tolerates splashes from wet grass. A digital brushless motor delivers efficient power, and push-button start is standard.

Its battery wraps each cell with cooling material to keep it powering on longer, a stated 25 percent longer, and the Auto PWR JUMP charger is a 150W unit that recharges faster. The kit includes a mulch plug and grass bag. Seven cutting heights give a wide range.

It is a push mower, so it lacks the Greenworks 21 inch's drive. A foldable handle stores vertically. Clean the deck and sharpen the blade. It suits mid-size lawns.

The Wild Badger is a 21 inch self-propelled mower like the Greenworks, but it includes two 40V 4.0Ah batteries and states up to 88 minutes of total runtime. Two packs mean you can finish a large lawn with a swap, which the single 5.0Ah pack on the Greenworks cannot do.

A 3,200 rpm brushless motor drives the deck, and the variable-speed drive adjusts to your pace. Seven cutting heights run from 1.18 to 3.55 inches, and four clipping modes cover bagging, mulching, side and rear discharge.

The brand is smaller, so support and parts are less proven. A three-year limited warranty is stated. Clean the deck and sharpen the blade. It suits medium to large lawns.

The Greenworks 17 inch is the straightforward value mower: a brushless motor, a 4.0Ah battery and a stated runtime of up to 35 minutes, enough for a quarter-acre lawn. It mulches or bags, and six cutting heights adjust with one lever.

It sits between the 16 inch push model and the 21 inch self-propelled unit, with a wider deck than the 16 inch and none of the weight of a self-propelled drive. The battery fits more than 75 Greenworks 40V tools, a real advantage if you own others.

A three-year warranty covers tool and battery. Clean the deck, sharpen the blade and store the battery indoors. It suits small to medium lawns.

The 16 inch Greenworks is the smallest and lightest mower here, listed as 35 percent lighter than steel-deck mowers. The maker claims it cuts up to a third of an acre on a 4.0Ah charge, though that varies with grass condition and technique.

It offers five cutting heights and a 2-in-1 mulch and rear-bag system. Compared with the 17 inch model, it has a narrower deck and does not list a brushless motor, so it is the entry choice.

It shares the 40V battery with 75 or more Greenworks tools. Wash the deck and sharpen the blade. It suits small lawns and storage-limited homes.
