8 Best Electric Lawn Mowers from Costco to Buy in 2025

The EGO POWER+ LM2101 comes out swinging with a 56V ARC Lithium system that feels purpose-built for homeowners who want gas-like punch without the fumes. Its 21-inch deck and one-handed height lever (1.5–4 inches) hit the sweet spot for most suburban yards, while IPX4 weather resistance and bright LED headlights add real-world convenience. A push-button start and compact folding handle make storage simple and startup instant—ideal if you’re tired of finicky pull-cords and seasonal maintenance.

In testing, the EGO handled mixed grass heights and thicker patches confidently, delivering up to 45 minutes of runtime with the included 5.0Ah pack. The 3-in-1 system (mulch, bag, side discharge) works well; the two-bushel bag fills evenly, and mulching doesn’t bog the motor on typical weekly cuts. At 21 inches, it covers ground efficiently, though very tall, wet grass can push the limits and reduce runtime—common for battery mowers in heavy conditions.

Compared with the Greenworks 40V self-propelled model, the EGO trades self-propel for slightly stronger overall power and a more weather-ready build. Versus the MightyMow 2x20V self-propelled, EGO feels more refined and robust, though you’ll walk it yourself. It’s best for homeowners who prioritize reliability, power density, and easy storage over powered wheels. Feature-for-feature, the EGO delivers a more premium feel than the Greenworks 48V push mower while maintaining stronger cutting capability.

MightyMow’s 2x20V self-propelled mower is a workhorse for big yards on a tighter budget, pairing a 21-inch steel deck with a brushless motor up to 3100 RPM. The dual 8.0Ah batteries promise up to 60 minutes with self-propel engaged (75 minutes push), tackling larger lawns without mid-mow swaps. The variable pace (2.0–4.3 ft/s) keeps hills and long stretches manageable, while the 3-in-1 setup handles mulching, bagging, or side discharge.

On grass between weekly cuts, it maintains steady blade speed and clears clippings fast thanks to boosted airflow. We found self-propel traction consistent on moderate slopes, with rear-weight balance that doesn’t feel nose-light. Height adjustment spans 1–3 inches—a bit shorter than competitors—so if you prefer high-cut summer turf, you may want more headroom. The steel deck adds durability but also some heft in tight turns.

Against the Greenworks 40V self-propelled mower, MightyMow offers longer claimed runtime and a lower entry point while sacrificing refined ergonomics and vertical storage. Versus the EGO LM2101, this is the better pick if self-propel is a must and you’re okay with slightly less polish. For larger suburban yards and mild slopes, it’s a value-forward choice with more stamina than the Greenworks 48V push model.

The Greenworks 40V self-propelled mower feels dialed-in for everyday reliability, combining a 21-inch steel deck with a smooth brushless motor and rear-wheel drive. The single-lever, 7-position height adjust provides more flexibility than most, and its vertical storage design frees up serious space in a crowded garage. Maintenance-free operation—no gas, oil, or pull-start—makes it easy to recommend as a weekly driver.

In yard testing, it delivers up to 45 minutes of runtime with the 5.0Ah pack, enough for medium lawns if you don’t push through soaked or overgrown turf. Rear-wheel self-propel provides better traction on slopes and uneven ground than front-drive setups, and the 3-in-1 capability performs cleanly across bagging, mulching, and side discharge. The motor keeps noise low, though heavy, wet grass will sap runtime and may require a slower pace.

Compared with the MightyMow self-propelled, the Greenworks offers more refined controls and storage but slightly less claimed runtime. Against the EGO LM2101, you gain self-propelled convenience at the expense of raw voltage and weather sealing. It’s ideal for homeowners who want balanced performance, tidy storage, and proven reliability. Feature-wise, it feels more complete than the Greenworks 48V push model for mid-sized lawns.

This MightyMow 40V push mower is a compact, punchy option for small to mid-size yards, pairing a high-speed 4200 RPM brushless motor with an 18-inch deck. Despite the smaller footprint, it includes a 40L grass bag and a 6-position height range from 1–3 inches, plus an adjustable handle for better ergonomics. Up to 40 minutes of runtime on dual 4.0Ah batteries suits weekly mowing routines.

In practice, the lightweight chassis makes trimming around beds and landscaping easy, and the higher blade RPM helps maintain cut quality in moderately thick grass. Mulching is effective on regular growth; bagging fills evenly with minimal clumping in dry conditions. The trade-off is coverage—18 inches means more passes—and runtime dips faster in tall, damp grass compared to 21-inch competitors.

Compared with the Greenworks 48V 17-inch push mower, this MightyMow brings a faster blade speed and larger bag, making it better for slightly bigger spaces. Versus the EGO LM2101, it’s more maneuverable but lacks the same power density and weather resistance. It’s a smart pick for owners who value nimble handling and a strong motor over maximum deck size.

Greenworks’ 48V push mower is a no-fuss, lightweight solution for small yards, built around a 17-inch rust-resistant poly deck that’s easy to maneuver. With two 24V batteries, it offers up to 45 minutes of runtime depending on grass conditions, and the 2-in-1 system supports mulching and rear bagging. The single-lever, 5-position height adjust covers common seasonal cuts without overcomplicating setup.

In tight spaces, the compact footprint shines—navigating around trees, edging, and narrow gates is straightforward. Push-button start and low noise suit early morning sessions, while the poly deck shrugs off moisture and won’t corrode. It’s not meant for heavy, wet overgrowth; expect slower progress and more frequent bag emptying on dense turf.

Against the MightyMow 40V 18-inch, this Greenworks is lighter and simpler, but the MightyMow’s higher RPM feels stronger in thick grass. Compared with the EGO LM2101, you sacrifice deck size and power for nimbleness and easy handling. Best for homeowners with small, flat yards who want reliable, minimal-maintenance mowing. Feature-by-feature, it’s more maneuverable than the MightyMow self-propel for tight plots.

This 40V self-propelled mower leans into feature-forward tech, headlined by EASYSURGE control and a 4100 RPM brushless motor that keeps blade speed steady in changing conditions. The standout is the world-first electric cutting height adjustment—six positions with a one-touch control, no bending required. A T-shaped single-rod handle folds quickly, making bag swaps and storage painless.

On-lawn performance is agile thanks to variable self-propel (1.3–2.9 MPH), keeping pace comfortable on flat sections and mild inclines. Runtime lands around 30 minutes per charge, enough for up to about 1/6 acre; plan for efficient passes to maximize coverage. The 18.5-inch deck is nimble, and cut uniformity stays consistent, though dense, wet grass will shorten runtime and may need a second pass.

Compared to the Greenworks 40V self-propelled, this model trades a smaller deck and shorter runtime for smarter controls and effortless height adjustment. Versus the MightyMow 2x20V self-propelled, you get more tech and ergonomics but less endurance. It’s perfect for homeowners who value ease-of-use and precision over raw battery stamina. Feature-to-feature, it’s more advanced in controls than the Greenworks 48V push mower.

The YARDCARE 36V upgrade is a lightweight, user-friendly mower that stands out with an LED display for battery, speed, and alerts—great for avoiding mid-mow surprises. Its brushless motor at 3200 RPM balances quiet operation with dependable cutting for small to medium lawns. With up to 60 minutes on low or 40 on high, it’s efficient for routine weekly trims.

Real-world use highlights its agility: the compact frame and 8-gallon bag keep cleanup simple, and the 5-position height range (0.98–2.56 inches) suits low-to-medium turf profiles. The three-step safety start adds peace of mind around kids and pets. It’s not built for thick, overgrown grass or steep slopes, but it excels in tight spaces and frequent, light maintenance cuts.

Compared to the Litheli 16-inch, YARDCARE offers more runtime transparency and better on-mower info via the LED readout. Against the Greenworks 48V push, it’s lighter and more communicative but doesn’t match the broader brand ecosystem. Best for homeowners prioritizing light weight, clarity, and easy handling. Feature-wise, it’s more approachable than the MightyMow 40V push for small yards.

The Litheli 16-inch mower is a super-compact specialist designed for patios, townhomes, and tight urban yards. Its 16-inch deck and lightweight chassis make it effortless to carry and store, and the adjustable handle reduces fatigue during long trims. With two 4.0Ah batteries, it’ll cover up to 2,700 sq. ft. on a charge—enough for tidy, frequent cuts.

On-lawn, the efficient motor keeps noise low and cut lines clean on short to mid-length grass, with a height range of 0.98–2.98 inches. The folding handle and built-in carry grip help it tuck into small sheds, and the battery platform can even reverse-charge devices for emergency top-ups. Expect slower progress in thick or wet grass due to the narrow deck and modest torque.

Compared with the YARDCARE 36V, Litheli is even more compact and slightly higher in max cut height, but lacks the LED status display. Versus the Greenworks 48V 17-inch, it’s easier to store and carry, but not as capable across larger areas. It’s ideal for users who want ultra-portability and minimal storage footprint. Feature-to-feature, it’s more compact but less versatile than the EGO LM2101.
