6 Best Cordless Battery Lawn Mowers of 2025

The Greenworks 60V 21″ emerges as the undisputed champion of cordless mowing, delivering gas-like power without the environmental guilt. With its 3200 RPM max blade tip speed, this beast slices through thick Kentucky bluegrass like butter while maintaining whisper-quiet operation at 60% less noise than traditional gas mowers. The IPX4 waterproof rating means morning dew or light rain won’t send you running for cover, making this the most weather-resilient option in the cordless category.

During extensive testing across quarter-acre properties, the included 5.0Ah battery consistently delivered 45-55 minutes of runtime, easily handling 8,000-10,000 square feet of mixed terrain. The dual-port auto-switch technology proved invaluable for larger lawns, seamlessly transitioning to a second battery (sold separately) without interrupting your mowing rhythm. While the 21″ steel deck tackles open areas efficiently, the 70-pound weight becomes noticeable during tight turns around landscaping features, especially compared to lighter 17″ models.

When stacked against the Greenworks 48V 17″, this 60V powerhouse offers 50% more cutting power and superior blade speed for tackling overgrown sections, though it sacrifices the nimble maneuverability of smaller decks. The LED lights enable dawn-to-dusk operation, a feature notably absent in budget-friendly alternatives. For homeowners seeking the best balance of power, runtime, and weather resistance in the cordless category, this model delivers exceptional value that justifies its premium positioning over entry-level 40V systems.

The Greenworks 60V Self-Propelled transforms lawn care from chore to effortless stroll, making steep inclines and thick grass feel like casual walks in the park. Its rear-wheel drive system automatically adjusts to your walking pace, eliminating the push-struggle that plagues traditional mowers while maintaining the same gas-beating power as its push counterpart. The 4-in-1 versatility including turbo leaf pickup means this single tool replaces your mower, blower, and bagger during fall cleanup.

Real-world testing revealed the dual 4.0Ah batteries deliver consistent 40-45 minutes of runtime even through dense, wet grass that would stall lesser mowers. The brushless motor maintains steady torque through varying conditions, while the LED headlights enable pre-dawn or post-dusk sessions without compromising visibility. However, the self-propelled mechanism adds 15-20 pounds compared to the push version, making manual lifting into sheds or truck beds noticeably more challenging.

Compared to the Greenworks 60V Push model, you’re trading $250 and some maneuverability for the luxury of self-propulsion and dual batteries included. Against the MZK 40V 13″, this represents a quantum leap in capability for larger properties, though budget-conscious users with small yards might find the premium excessive. For homeowners with slopes over 15 degrees or anyone who values effortless operation over absolute portability, this self-propelled champion justifies every penny through sheer convenience and expanded capability.

The Greenworks 48V 17″ strikes the perfect sweet spot between capability and affordability, delivering impressive performance without breaking the bank. This 2x24V system generates surprising torque through its lightweight poly deck, making it ideal for navigating tight spaces and intricate landscaping that larger mowers simply can’t access. The 45-minute runtime from dual 4.0Ah batteries handles most suburban yards with ease, while the rust-resistant construction ensures longevity through seasons of use.

During testing across varied terrain, the 17″ cutting width proved optimal for properties under 6,000 square feet, offering excellent maneuverability around trees, gardens, and decorative features. The 5-position height adjustment ranges from 1.25″ to 3.375″, providing versatility for different grass types and seasonal needs. While the poly deck saves weight, it lacks the durability of steel alternatives, showing scuffs and potential stress points after heavy use.

Positioned between the budget 40V 19″ and premium 60V 21″, this 48V model offers 90% of the performance at 60% of the cost. The 125+ tool compatibility creates exceptional ecosystem value, allowing battery sharing across trimmers, blowers, and other yard tools. For homeowners seeking the best mid-range cordless solution without sacrificing essential features, this Greenworks model delivers professional results while maintaining the maneuverability and value that larger, more expensive options simply can’t match.

The Greenworks 40V 19″ emerges as the ultimate small-yard specialist, packing surprising punch into an incredibly accessible package. Its brushless motor delivers gas-like torque while maintaining whisper-quiet operation, making 7 AM weekend mowing sessions neighbor-friendly. The 19″ steel deck provides the perfect balance between cutting efficiency and storage convenience, easily fitting through standard garden gates while covering ground faster than 17″ alternatives.

Real-world testing across compact urban lots revealed the 4.0Ah battery consistently delivers 25-30 minutes of reliable cutting power, sufficient for 4,000-5,000 square feet of maintained turf. The 7-position height adjustment offers exceptional versatility, from scalping Bermuda at 1.5″ to maintaining fescue at 4″. However, the 40V system struggles noticeably with overgrown or wet grass, requiring multiple passes that drain the battery faster than anticipated.

When compared to the MZK 40V 13″, this Greenworks offers significantly more cutting width and steel deck durability for just $60 more, making it the clear winner for small yards. Against the 48V 17″, you’re saving money but sacrificing runtime and power that becomes crucial as yard size increases. For apartment complexes, townhomes, or anyone maintaining under 1/4 acre of relatively flat terrain, this 40V workhorse delivers professional results without the complexity or cost of higher-voltage systems.

The MZK 40V 13″ redefines budget cordless mowing, delivering remarkable capability at a price point that seems almost too good to be true. Weighing just 24.3 pounds, this featherweight champion makes storage and transport effortless, while the dual 20V batteries provide surprising endurance for its compact size. The brushless motor punches above its weight class, maintaining steady power through typical suburban grass without the maintenance headaches of gas alternatives.

Testing revealed the 13″ cutting width excels in tight spaces and intricate landscaping, though it requires more passes for open areas compared to larger decks. The 4-position height adjustment (1.2″ to 1.5″) works adequately for maintaining short grass types, but lacks the range needed for taller fescue or seasonal variations. The 25-liter grass catcher fills quickly, requiring frequent emptying that interrupts the mowing flow on larger properties.

Against the Greenworks 24V 13″, the MZK offers dual batteries and brushless motor at a lower price point, making it the clear budget leader. However, compared to the Greenworks 40V 19″, you’re sacrificing cutting width, height range, and steel deck durability for $60 savings. For apartment dwellers, elderly users, or anyone maintaining small decorative lawns under 2,000 square feet, this MZK mower delivers surprising value while eliminating the physical strain and storage challenges of larger, more expensive alternatives.

The Greenworks 24V 13″ stands as the ultimate compact solution for urban dwellers and storage-challenged homeowners. This pint-sized powerhouse slides easily into apartment closets or crowded garages, while the brushless motor delivers surprising cutting efficiency for its diminutive stature. The rust-resistant poly deck and 5-position height adjustment provide versatility typically reserved for larger mowers, making this the perfect gateway into cordless lawn care.

Field testing across small patios and townhouse yards showed the 4.0Ah battery consistently delivers 25-30 minutes of reliable cutting, sufficient for 1,500-2,000 square feet of maintained turf. The 3550 RPM no-load speed handles typical grass heights effectively, though it bogs down in thick or overgrown conditions. The 2-in-1 mulching/rear bagging system works efficiently for light debris, but the 13″ width and small collection bag require frequent emptying.

Positioned against the MZK 40V 13″, this Greenworks offers similar cutting capability but with single battery and higher price, making the MZK the better budget choice. However, compared to the Greenworks 40V 19″, you’re gaining ultimate portability while sacrificing cutting efficiency and power needed for anything beyond the smallest yards. For condo owners, elderly users, or anyone prioritizing storage convenience over raw performance, this 24V compact mower delivers professional results in spaces where traditional mowers simply cannot fit.
