6 Best GreenWorks Electric Lawn Mowers of 2025

This 80V powerhouse redefines what a cordless mower can achieve, delivering gas-matching torque and relentless runtime thanks to its high-voltage brushless motor and 4.0Ah battery. With a 21-inch steel deck, it slices through thick grass with surgical precision, while the self-propelled rear-wheel drive eliminates leg strain—perfect for sloped or sprawling lawns. It’s engineered for homeowners who demand pro-level performance without the noise, fumes, or maintenance of gas engines.

In real-world testing, the mower consistently handled ½-acre yards on a single charge, even in tall, damp grass. The variable speed control lets you adjust pace seamlessly, maintaining traction on uneven terrain, while the LED headlights extend mowing into early mornings or twilight. Though the battery takes about 60 minutes to recharge with the rapid charger, it’s a small trade-off for the turbo leaf pickup mode and 4-in-1 versatility—mulching, bagging, side discharge, and leaf clearing—all from one deck. It falters slightly on extremely hilly terrain above 15 degrees, where momentum matters.

Compared to the 40V models, this 80V is in a different league—more power, more runtime, more control—positioning it as the ultimate upgrade for serious homeowners. It outmuscles the Greenworks 40V 21” and even rivals gas mowers in cut quality and consistency. While it’s heavier and pricier than entry-tier models, its long-term durability, quiet operation (3x quieter than gas), and compatibility with 75+ 80V tools make it a smarter long-term investment than the mid-range 60V variant.

The Greenworks 40V 21” strikes a masterful balance between power, portability, and value, making it the sweet spot for mid-sized yards up to ½ acre. Its brushless motor delivers consistent torque and whisper-quiet operation, while the 5.0Ah battery pushes runtime to 45 minutes—enough for most suburban lawns. The self-propelled rear-wheel drive is a game-changer, reducing fatigue on longer mowing sessions and conquering uneven terrain with confidence.

During testing, it excelled on flat to moderately sloped lawns, easily cutting through overgrown patches without bogging down. The 7-position single-lever height adjustment made switching between cutting heights effortless, and the 3-in-1 system (mulch, bag, side discharge) offered solid versatility. While it can’t match the raw power of the 80V model, it holds its own—just don’t expect it to power through wet, knee-high grass without slowing. The vertical storage feature is a standout, cutting garage footprint by 70%, ideal for tight spaces.

Against the 40V 16” push mower, this model offers better coverage and self-propulsion, while undercutting the 80V in price and weight. It’s perfect for homeowners who want gas-like performance without complexity—no oil, no gas, no pull starts. Though it lacks LED lights and turbo modes, its maintenance-free operation and longer battery life make it a more practical daily driver than the budget twin-blade model.

Light, agile, and effortless to start, the Greenworks 40V 16” is a dream for small yards and novice mowers who value simplicity and ease. Weighing significantly less than its 21-inch cousins, it’s a breeze to maneuver around flower beds, trees, and tight corners—perfect for yards under ½ acre. The brushless motor still delivers strong torque for a compact machine, and the 4.0Ah battery reliably lasts up to 45 minutes, depending on grass density.

In real use, it shines in low-to-medium grass conditions, offering a clean, even cut with minimal vibration. The 5-position single-lever height adjustment is intuitive, and while it only supports mulching and rear bagging, that’s sufficient for most small-lawn owners. It struggles slightly in thick, wet grass—where the narrower deck and lower torque require slower passes. Still, the push-button start and instant power-up eliminate the frustration of gas mowers, and the 3-year warranty on both tool and battery adds peace of mind.

Compared to the 40V 21” self-propelled model, this one sacrifices power and propulsion for lightweight agility and lower cost. It’s not built for large or hilly yards, but for apartment complexes, townhouses, or elderly users, it’s ideal. While the twin-blade 20” model offers better cut quality, this one wins on weight and ease of storage—a smarter pick if you prioritize convenience over raw performance.

Built for large yards and demanding mowing schedules, the 60V 21” self-propelled mower is a runtime beast—equipped with two 4.0Ah batteries that enable back-to-back mowing without downtime. The dual-port rapid charger keeps one battery ready while you use the other, making it a top contender for ½ acre or larger properties. Its rear-wheel self-propelled drive powers through thick grass and slopes with ease, while the LED headlights ensure visibility in low-light conditions.

Performance is consistently strong: it maintains high blade speed even in dense patches, and the 4-in-1 system (mulch, bag, side discharge, turbo leaf pickup) adds serious utility beyond mowing. The brushless motor runs 3x quieter than gas, and the eco-friendly design means zero emissions and no messy fuel. However, swapping batteries mid-mow can be awkward, and the 45-minute per battery runtime may still require a pause on very large lawns—though less than single-battery models.

When stacked against the 80V 21”, it trades some peak power for broader ecosystem compatibility with 75+ 60V tools. It’s lighter than the 80V but not quite as aggressive on tall grass. For users already in the 60V Greenworks ecosystem, this mower offers seamless integration and extended runtime—a smarter value than upgrading to 80V unless you need maximum torque.

Don’t let its budget-friendly label fool you—the 40V 20” twin-blade mower punches above its weight with exceptional cut quality and smart design innovations. The dual blades create a finer mulch and cleaner cut than single-blade rivals, while Smart Cut Technology automatically adjusts power based on grass thickness—a rare feature at this price. With both a 4.0Ah and 2.0Ah battery, you gain flexibility: use one for small jobs, swap or combine for longer runs.

In testing, it handled medium-height grass with impressive efficiency, and the auto-switch battery system allowed seamless transitions—no shutdowns to swap packs. The 20-inch deck covers more ground than the 16” model, making it a solid mid-tier option. However, the plastic housing feels less durable, and the mower lacks self-propulsion, requiring more physical effort on larger lawns. It’s best suited for flat, small-to-medium yards where precision and mulching matter more than speed.

Against the 40V 21” self-propelled, it loses on ease of use but wins on cut refinement and value. It’s not as powerful as brushless models, yet the twin blades and smart tech make it the best budget pick for clean finishes. While the 48V 20” model offers better mulching, this one delivers more battery flexibility and a lower entry point—ideal for cost-conscious buyers who still want premium features.

If mulching performance is your top priority, the 48V 20” mower is a hidden gem—its 4-in-1 system with Turbo Button delivers exceptional mulch fineness and leaf pickup power, rivaling dedicated mulchers. By combining two 24V batteries, it hits 48V of peak power, offering gas-comparable torque in a compact frame. The brushless motor ensures longevity and quiet operation, while the LED headlight extends usability into dim conditions.

Real-world tests confirmed its superior mulching capability, leaving behind a near-invisible grass residue that feeds the lawn naturally. The dual 4.0Ah batteries and dual-port rapid charger mean minimal downtime, and the 45-minute runtime per charge handles most yards. It’s also compatible with 125+ tools in the 24V ecosystem, making it a smart hub for cordless gardening. However, it’s not self-propelled, so pushing it on wet or dense grass can be tiring.

Compared to the 40V twin-blade model, this one offers better power, better mulching, and LED lighting, making it the clear upgrade for eco-conscious lawn caretakers. While the 60V 21” covers more ground, this 48V model excels in sustainability and ecosystem value. It’s the best choice if you want professional-grade mulching without gas or noise—outperforming every other 40V model in refinement and long-term utility.
