6 Best Green Lawn Mowers to Buy in 2025

This beast of a mower redefines what cordless can do—80V power, a 21-inch steel deck, and a brushless motor team up to deliver gas-level performance without the noise, fumes, or maintenance. With self-propelled rear-wheel drive and variable speed control, it conquers slopes and thick grass like a pro, making it a dream for homeowners with half-acre lots or uneven terrain. If you’re tired of pushing heavy mowers or wrestling with gas engines, this model slashes effort and noise while maximizing cutting efficiency.

In real-world testing, the mower consistently handled tall, damp grass with ease, thanks to the high-torque brushless motor and wide 21” deck that reduces pass count. The 4.0Ah battery delivers 45–60 minutes of runtime, more than enough for most suburban lawns, and the rapid charger gets you back to work in under an hour. The LED headlight is a game-changer for early morning or dusk mowing, and the 4-in-1 system (mulch, bag, side discharge, turbo leaf pickup) adds serious seasonal versatility. It does struggle slightly in extremely overgrown fields, where a second battery might be needed, but for typical lawn care, it’s remarkably resilient.

Compared to the 60V self-propelled model, this 80V version offers noticeably stronger torque and longer runtime, making it better suited for larger or tougher lawns. While it’s pricier than mid-tier options, the performance leap justifies the cost for serious homeowners. It’s the top-tier choice for those who want maximum power and autonomy without going gas—outpacing mid-range models in both speed and stamina while integrating seamlessly into Greenworks’ 75+ tool ecosystem.

Field tests show it powers through thick grass with minimal slowdown, and the dual batteries extend runtime to 75+ minutes, eliminating mid-mow anxiety. The rapid dual-port charger is a major win, fully recharging both packs in under an hour. While the motor isn’t quite as punchy as the 80V model, it’s more than capable for standard mowing tasks and excels in maneuverability. It does require occasional deck cleaning in wet conditions, but overall, it’s reliably efficient and built for real-world consistency.

Against the 80V model, it trades a bit of peak power for better value and included extras—two batteries and a dual charger out of the box. It’s also more accessible than the budget 40V line while offering longer runtimes and self-propulsion. This is the perfect middle ground for families with medium to large yards who want strong performance, extended runtime, and ecosystem compatibility—delivering nearly flagship-level features without the top-tier price tag.

Don’t let the compact size fool you—this nimble powerhouse packs a brushless motor into a 16-inch frame, making it a standout for small yards and effortless handling. Weighing significantly less than bulkier models, it’s incredibly easy to push and store, yet still delivers 45 minutes of runtime on a single 4.0Ah battery—enough for lawns up to half an acre under ideal conditions. The single-lever 5-position height adjustment ensures a clean, customized cut, while the 2-in-1 mulching and bagging system keeps clippings under control with minimal fuss.

In testing, it handled dry, short-to-medium grass with impressive efficiency, and the brushless motor provided smooth, quiet starts every time—no tugging or priming. It’s not built for thick, wet overgrowth or steep hills, but for flat, well-maintained lawns, it’s surprisingly capable. The lightweight design is a major win for older users or those with limited strength, and the push-button start eliminates the frustration of pull cords. However, in dense grass, it can bog down, requiring slower passes.

Compared to the 40V 19” model, it sacrifices cutting width for superior portability and ease of use. It’s also less powerful than self-propelled options but shines as a low-effort, no-maintenance solution for smaller spaces. This is the go-to for urban yards, condos, or light-duty mowing, offering brushless efficiency in a compact, user-friendly package—beating budget models in motor quality while costing less than larger, self-propelled units.

This hidden gem delivers 48V of combined power from two 24V batteries, creating a rare blend of compact platform compatibility and serious cutting strength. The 20-inch steel deck covers more ground than 16” models, while the brushless motor ensures quiet, durable performance with up to 45 minutes of runtime—perfect for small to medium yards. The LED headlight extends mowing hours, and the 4-in-1 system (including turbo leaf pickup) adds seasonal flexibility few in its class can match.

In real use, it handled average grass height with confidence, and the dual batteries provide redundancy—swap one mid-mow if needed. The dual-port rapid charger is a major convenience, fully recharging both packs efficiently. It’s not self-propelled, so you’ll feel the effort on larger lawns, and the deck can clog in wet conditions, requiring frequent cleaning. But for its size, the torque and runtime are impressive, especially given its integration with the 24V ecosystem.

Against the 40V 16” model, it offers wider cuts and more power, while still being lighter than 21” mowers. It’s also more versatile than basic 2-in-1 models with its full 4-in-1 functionality. This is the best pick for those already in the 24V Greenworks ecosystem or those wanting more power than 40V but without stepping up to 60V/80V—delivering broader coverage and extra features while maintaining platform synergy and compact charging.

This budget-savvy performer proves you don’t need high voltage to get gas-like results—with 45 minutes of runtime, whisper-quiet operation, and zero emissions, it’s a smart pick for eco-conscious homeowners with small lawns. At 35% lighter than traditional mowers, it’s effortless to push and store, and the ergonomic handle and push-button start make it accessible for all ages. The single-lever height adjustment and 2-in-1 mulching/bagging system deliver solid versatility for basic lawn care.

In testing, it performed well on dry, short grass but struggled with taller or damp patches, where it required multiple passes. The 4.0Ah battery takes 2 hours to charge, which can be a bottleneck if you’re in a hurry. Still, for flat, well-kept lawns under half an acre, it’s reliable and low-maintenance, with the added perk of integrating into Greenworks’ 75+ tool ecosystem. It’s not built for heavy-duty use, but for light, regular mowing, it delivers consistent value.

Compared to the 40V 16” brushless model, it lacks the brushless motor’s efficiency and longevity, relying on a standard motor that may wear faster under strain. But it includes the same battery and charger setup at a competitive price. This is the ideal starter mower for renters, seniors, or small-yard owners who want affordable, no-fuss cutting—offering essential features without extras, making it a practical entry point into cordless mowing.

This under-the-radar workhorse is built for homeowners who need more deck width without stepping up to self-propelled models—the 19-inch steel deck cuts broader swaths than 16” mowers, reducing mowing time significantly. Powered by a brushless motor and 4.0Ah battery, it delivers smooth, quiet starts and 30 minutes of runtime, ideal for larger yards where efficiency matters. The 7-position single-lever height adjustment offers precise control, and the 2-in-1 mulch and side discharge system handles clippings with ease.

In real-world use, it powered through medium-height grass with confidence, though runtime drops fast in dense or wet conditions—users may need a spare battery for lawns over 0.3 acres. It’s not self-propelled, so pushing it over large areas can be tiring, and the 30-minute runtime is the shortest in its class. Still, the brushless motor ensures durability and efficiency, and the maintenance-free design (no gas, no oil) keeps upkeep simple. It’s a no-nonsense performer for those prioritizing cutting width and motor quality over bells and whistles.

Against the 40V 16” brushless model, it offers better coverage per pass but less runtime and no rear bagging. It’s also narrower than 20”+ models but more affordable. This is the best choice for larger yards under 0.5 acres where you want brushless reliability and faster mowing without self-propulsion—delivering greater efficiency than smaller models while staying within budget, making it a smart upgrade for serious mowers.
