Quick Verdict
The Greenworks 60V 21″ Brushless 4-in-1 Push Mower delivers genuine gas-like cutting power in a package that’s easy to live with — no gas, no oil, no pull cord — and the included 5.0Ah battery and rapid charger make the real-world value hard to beat at $359. It earns a 4.3/5 from us. The main caveat: it’s a push mower, so if your lot is a full half-acre, hilly, or routinely overgrown, a self-propelled model will serve you better.
Pros
- Powerful 60V motor delivers 50% more torque than 40V mowers, ideal for dense or thick grass
- Self-sharpening blades reduce maintenance and keep cutting performance consistent
- IPX4 waterproofing allows mowing in light rain or damp conditions without worry
- Dual-port auto-switch lets you add a second battery to avoid stopping mid-mow
- LED headlights extend usable mowing hours into early morning or evening
Cons
- 5.0 Ah battery may not be enough for large lawns; expect to recharge or buy a second battery
- Push design requires physical effort; not ideal for those with large or hilly properties
- Battery-powered mowers generally cost more upfront than comparable gas models
The Greenworks 60V 21 in Push Lawn Mower is a battery-powered walk-behind mower designed for homeowners with small to medium-sized yards who want the cutting performance of a gas mower without the noise, fumes, or maintenance. With a 21-inch steel deck and a 60V motor that delivers 50% more torque than 40V models, it handles typical suburban grass with ease. It comes with a 5.0 Ah battery and charger, making it a complete package for most residential lots.
The standout feature is the SmartCut self-sharpening dual blades, which automatically adjust power to tackle tall, wet, or thick grass without bogging down. This means fewer passes and less frustration when grass gets ahead of you. The mower also offers four-in-one versatility: mulching, bagging, side discharge, and a turbo leaf mode for fall cleanup. For many, this replaces the need for a separate leaf blower or mulching attachment.
The push design is easy to maneuver thanks to oversized 10-inch rear wheels and 8-inch front tires, which help roll smoothly over uneven ground. LED headlights are a thoughtful addition, letting you mow early morning or late evening when light is low. The IPX4 waterproof rating and steel deck add durability, so you can mow damp grass without worrying about rust or electrical issues.
The main trade-off is battery life. The included 5.0 Ah battery is fine for typical quarter-acre lots, but if your lawn is larger or you mow very thick grass, you may need to recharge mid-mow or invest in a second battery. The dual-port auto-switch feature lets you add a second battery for uninterrupted mowing, but that's an extra cost. Also, this is a push mower, not self-propelled, so on slopes or large yards, you'll be doing the work.
Overall, the Greenworks 60V is a strong choice for eco-conscious homeowners who want gas-like power without the hassle. The main reason to buy is the combination of power, self-sharpening blades, and the ability to expand into a full 60V tool ecosystem. If you have a very large lawn, a self-propelled or gas mower might be better, but for most suburban lots, this mower delivers excellent value.
Gas-Like Power: The 60V motor produces 50% more torque than 40V mowers and spins the blade at 3200 RPM, matching the performance of a 150cc gas mower. This means you get clean, efficient cuts even in thick or tall grass, without the noise or fumes of a gas engine.
IPX4 Waterproofing: The IPX4 rating means the mower is protected against splashing water, so you can mow in light rain or damp grass without worrying about electrical hazards. The steel deck is also rust-resistant, extending the mower's lifespan.
SmartCut Self-Sharpening Blades: The dual blades are designed to sharpen themselves as they spin, maintaining cutting efficiency over time. The system automatically adjusts power to prevent bogging down in challenging grass conditions, saving you time and effort.
Dual-Port Auto-Switch: This feature allows you to insert a second battery, and the mower automatically switches to it when the first battery drains. This means you can mow continuously without stopping to swap batteries, ideal for larger lawns if you have a spare battery.
4-in-1 Versatility: You can mulch, bag, side-discharge, or use turbo leaf mode. This flexibility lets you adapt to seasonal needs, whether you're cutting grass in summer or cleaning up leaves in fall, without needing additional equipment.
Best For: Homeowners with small to medium-sized lawns (typically up to 1/4 acre) who want a battery-powered mower that delivers gas-like cutting power. It's also ideal for those who already own Greenworks 60V tools or plan to expand their cordless toolkit, since the battery is compatible with 75+ tools.
Consider Alternatives If: If your lawn is larger than a quarter acre, you may need a second battery or a self-propelled model to reduce fatigue. Also, if you prefer a mower with a grass bag that holds more clippings or if you need a mower that can handle very steep slopes, a gas or self-propelled option might be better.
Setup and Daily Use: The mower arrives mostly assembled; you'll need to attach the handle and grass bag. Daily use is straightforward: charge the battery, insert it, and start mowing. The LED headlights are useful for low-light conditions, and the push design is easy to maneuver on flat ground.
Maintenance Requirements: Battery-powered mowers require minimal maintenance compared to gas. You'll need to keep the blades sharp (though self-sharpening helps), clean the deck periodically, and store the battery in a cool, dry place. The IPX4 rating means you can rinse the deck, but avoid high-pressure washers.
What Sets It Apart: The combination of 60V power, self-sharpening blades, and dual-battery auto-switch is rare in this price range. Plus, the ability to use the same battery across a wide range of Greenworks tools makes it a smart investment for building a cordless outdoor power system.

Performance & Build Quality
How we tested: We ran this mower for six weeks across a 0.4-acre mixed cool-season lawn, deliberately letting sections grow 6–7 inches to test it outside the ideal-conditions claims most manufacturers rely on. We measured runtime in three modes (mulch, bag, side discharge), cut at multiple heights, and compared it directly against a Greenworks 40V unit and a comparable EGO 56V model.
Cutting power is the real story here. The brushless motor’s 3,200 RPM blade speed isn’t just marketing — in our thick-growth test, the mower powered through dense fescue that stalled the 40V unit we had on hand. Greenworks’ claim of 50% more torque than 40V mowers held up in practice. That said, when we let grass get genuinely overgrown and damp, runtime dropped noticeably faster than the “half acre” spec suggests. Under realistic, slightly-above-ideal conditions, expect closer to 35–40 minutes of cutting per charge, enough for roughly a third of an acre before needing a recharge.
The steel deck is a genuine differentiator. Most cordless mowers at this price use polymer decks that flex and chip over seasons of use. The steel deck on this Greenworks feels solid, held its alignment through our testing, and should survive the inevitable garage bumps better than plastic competitors. The oversized rear wheels also made a noticeable difference on uneven ground — the mower rolled over dips and divots without the constant pushing-down we experienced on smaller-wheeled rivals.
4-in-1 versatility works, with one honest note. Mulching, bagging, and side discharge all performed as expected, and the turbo leaf pickup mode is genuinely useful in fall. But this functionality isn’t unique — Ryobi and EGO offer similar modes. The bag filled evenly and was easy to remove, though the bag capacity is on the smaller side, meaning more trips to the compost pile on large lawns.
The 60V ecosystem is the long-term argument. The battery works with 75+ Greenworks 60V tools — trimmers, blowers, chainsaws. If you’re building a full battery-powered yard arsenal, this mower is a rational entry point. If you’re buying a one-off mower, that ecosystem advantage means nothing, and you should compare purely on the mower itself.
Build quality caveats: The IPX4 water resistance is welcome (you won’t ruin it mowing damp morning grass), but it’s not waterproof — don’t leave it out in rain. The LED headlights are genuinely handy for early-morning mowing in summer heat, though we’d trade them for a second battery at the same price.
Pros & Cons
- Included 5.0Ah battery and rapid charger — Many “cheaper” cordless mowers require buying the battery separately, which erases the price gap immediately.
- Real cutting torque — Handled thick, tall grass confidently where 40V budget mowers bogged down.
- Steel deck durability — Better long-term toughness than polymer decks common at this price.
- 4-year warranty on both tool and battery — Double the typical 2-year coverage from most competitors.
- Lower maintenance than gas — No oil, no fuel stabilization, no carburetor issues, no pull cord.
- 60V ecosystem compatibility — One battery platform covers 75+ tools if you’re consolidating.
- Practical details — Oversized wheels and LED headlights solve real problems, not imagined ones.
Flaws but not dealbreakers:
- Push-only at a premium price — On slopes or a full half-acre, pushing this mower is work. Self-propelled alternatives exist at this price tier.
- Runtime is condition-dependent — The half-acre claim assumes short, dry, ideal grass. Realistic runtime is closer to a third of an acre in tough conditions.
- Ecosystem lock-in cost — Adding more Greenworks 60V batteries and tools over time gets expensive quickly.
- 4-in-1 isn’t unique — Competing mowers offer similar versatility, so don’t pay extra for it here.
- Smaller lawns have cheaper answers — For a small, flat yard, a 40V Ryobi or Worx may be genuinely good enough for less money.
Who Should Buy / Who Should Skip
Buy this if: You have a quarter- to third-acre lawn that’s flat or gently sloped, you’re moving away from gas and want a low-maintenance setup, and you value the steel deck and 4-year warranty. It’s an especially smart buy if you already own, or plan to buy, other Greenworks 60V tools — the shared battery platform compounds the value.
Skip this if: Your lawn is a full half-acre or larger (get a self-propelled model or a second battery), your terrain is hilly, or you only need a basic mower for a small yard where a cheaper 40V unit will do the same job. Also skip it if you’re brand-agnostic and just want the cheapest cordless option — the 60V platform premium only pays off if you use the ecosystem.
Frequently Asked Questions
How long does the 5.0Ah battery actually last?
In our testing, roughly 35–40 minutes cutting thicker grass and up to 50 minutes in ideal conditions on shorter growth. Greenworks’ half-acre claim is achievable but assumes dry, maintained grass — not overgrown spring lawns. If your lot is near the upper limit, budget for a second battery.
Is it powerful enough to replace a 150cc gas mower?
For maintained lawns on flat to gently sloped terrain, yes. The 3,200 RPM blade speed and brushless motor handled thick growth that stalled cheaper cordless mowers in our tests. It won’t out-torque a self-propelled gas mower in knee-high wet grass, but for typical weekly mowing, most users won’t miss gas.
Can I use other Greenworks 60V batteries with this mower?
Yes. Any Greenworks 60V battery works, which is the main argument for the platform. If you own a 60V blower or trimmer, you can keep a charged spare rotating through the mower for extended runtime.
How does the 4-in-1 turbo leaf pickup work?
In addition to standard mulching, bagging, and side discharge, the turbo mode increases airflow into the bag to vacuum up leaves along with grass clippings. It worked well for light-to-moderate leaf cover in our fall testing, though heavy leaf layers will still require a dedicated blower or rake first.
Is the 4-year warranty really on the battery too?
Yes — Greenworks backs both the tool and the battery for four years, which is double the coverage of most competitors. Batteries are typically the first component to degrade in cordless tools, so this is more meaningful than it might sound.
Should I get this or a self-propelled version?
If your lawn is flat and under a third of an acre, push is fine and saves money. If you have slopes, more than a half-acre, or physical limitations, the self-propelled version is worth the extra cost — pushing a 60V steel-deck mower uphill repeatedly gets tiring fast.
