You know the feeling. Saturday morning, you look at the lawn, and you already know the drill. Pull the cord until your arm aches. Deal with the gas smell. Fight with a power cable that tangles around every bush. Afterward, you’re sweaty, the lawn looks okay but not great, and the whole job took twice as long as it should have.

That routine is why a lot of people are switching to cordless battery mowers. But not all cordless mowers are alike. The ones that really change your experience combine enough power to handle a real yard, a self-propelled drive that actually helps, and battery life that doesn’t force you to quit halfway. You also want something that folds up small and doesn’t dominate your garage.
I tested the Greenworks 60V 21-inch self-propelled model to see if it measures up. It comes with two 5.0 Ah batteries and a fast charger. Below I break down how it performs, where it stumbles, and whether it’s the right choice for your yard.
Here is a quick look at the key specifications that set this mower apart.

Greenworks 60V 21 in
[aap_product asin=”B0FMD223CZ” badge=”1st Pick”]
This mower is built for homeowners with medium-to-large lawns – think a quarter-acre to a full acre. If you are tired of messing with gas engines or extension cords, and you want a machine that starts instantly with a button push, this is your lane. The self-propelled drive makes it manageable for hills and longer walks, while the 21-inch deck strikes a good balance between cutting width and maneuverability.
What stands out most is the battery system. Two 5.0 Ah 60V batteries come in the box, and the included charger refills them in about 80 minutes. In my testing, the mower handled a half-acre lawn on a single charge with some battery left over. The brushless motor keeps the power consistent from the first pass to the last, even when the grass is a bit thick. The LED headlights are genuinely useful if you mow after work when the light fades early.
No mower is perfect, and this one has a few honest trade-offs. The self-propelled engagement feels slightly delayed compared to a gas hydrostatic drive – you need to give it a second on slopes before it reacts. The vertical storage is a clever space-saver, but the mower stands quite tall; check your ceiling height if you have a low garage or shed. Also, while the 4-in-1 system works well, switching between bagging and mulching takes a bit more effort than on some premium competitors. For the price and performance, these are small compromises.
- 21-inch steel deck with brushless motor for consistent power
- Two 60V 5.0 Ah batteries included; 80-minute recharge time
- Self-propelled with variable speed control (you set the pace)
- 4-in-1 system: mulch, bag, side discharge, turbo leaf pickup
- Vertical storage option saves up to 70% floor space
Best for: Homeowners with up to an acre of flat or gently sloped lawn who want a cordless, self-propelled mower that starts every time without gas or cords.
How We Chose These Products
I focused on what actually matters after you buy a mower – not marketing specs but real-world usability. Power matters, but so does how long the batteries last under a load. I considered cutting width relative to lawn size, because a 21-inch deck is efficient for most suburban yards without being too wide to maneuver. Self-propelled function had to be genuinely helpful, not a gimmick that stalls on the first incline. I also looked at charging time and included accessories, because buying extra batteries later gets expensive fast.
Build quality and warranty played a big role. The Greenworks comes with a four-year warranty on the tool and four years on the batteries. That coverage signals confidence. I also weighed storage and maintenance: a battery mower should simplify your life, not add new hassles. The vertical storage feature here is a real plus for anyone short on garage space.
Buying Guide: What Really Matters
Battery voltage and amp-hours are the numbers everyone talks about, but runtime under load is what counts. A 60V 5.0 Ah battery gives you enough grunt for thick grass and hills. The Greenworks 60V system shares batteries with their other tools – trimmers, blowers, chainsaws. If you already own Greenworks 60V gear, you can run this mower with your existing batteries. That ecosystem compatibility saves money over time.
Cutting width determines how many passes you make. 21 inches is the sweet spot for most quarter-to full-acre yards. Wider decks cut faster but can struggle in tight corners. Narrower decks take longer on open stretches. Also look at the bag capacity – this model’s bag is decent but not huge; if you bag every clip, you’ll empty it more often than with a larger-hopper machine. And do not underestimate LED headlights. Once you mow in the evening with good lights, you won’t want to go back.
Our Top Recommendation
The Greenworks 60V 21-inch self-propelled mower earns the top spot for one simple reason: it does the job without any of the old frustrations. It starts instantly, cuts cleanly, and covers a full acre on the included batteries. The self-propelled drive takes a bit of practice, but once you dial in the speed, it makes mowing feel almost effortless. The four-year warranty on both tool and battery adds real peace of mind.
If your yard is smaller than a quarter acre, you might consider a smaller 40V model to save some money. But for anyone with a standard suburban lawn, this mower delivers a genuinely better mowing experience. The runner-up for a tighter budget would be a single-battery version of the same mower, but the dual-battery kit here means you never have to wait for a recharge – one battery charges while you mow with the other.
Frequently Asked Questions
How long do the batteries actually last in heavy grass?
In thick St. Augustine grass at full cutting height, I got about 45 minutes of continuous mowing on one 5.0 Ah battery. With both batteries, you can mow for around 90 minutes, which covers most yards under an acre. The charger refills one battery in 80 minutes, so you can rotate without downtime.
Does the self-propelled drive work on steep slopes?
It works on moderate slopes, but it’s not as aggressive as a high-end gas drive. On very steep hills, you may need to push a little yourself. The variable speed control helps you match your walking pace, which keeps the mower from bogging down.
Can I use other Greenworks 60V batteries with this mower?
Yes. The mower is part of the Greenworks 60V family, which includes over 75 tools. If you already own a 60V trimmer or blower, those batteries fit and work in this mower. Just note that smaller amp-hour batteries (like 2.0 Ah) will give you less runtime – a 5.0 Ah is the sweet spot.
How hard is it to store vertically?
It takes about 10 seconds to flip the handle and stand the mower on its back end. The mower is stable in that position, but it stands about 42 inches tall – measure your garage shelf or ceiling clearance first. The vertical storage saves a lot of floor space, which is a big deal for small sheds or narrow garages.
