Greenworks is one of the best-known names in battery-powered lawn equipment, and its 40V line is the one most homeowners meet first. “40V” is the battery voltage, and the same battery slides into more than 75 Greenworks 40V tools, from trimmers to blowers to chainsaws. For a first-time homeowner that is a big deal: one charger and one or two batteries can run most of the yard, with no gas, oil or pull cords.
The six mowers below differ mainly in deck width (16, 17, 21 or 25 inches), whether you push them yourself or the mower drives its own wheels, and whether the box includes extra tools like a trimmer and blower.

Greenworks 40V 16in Push Lawn Mower
Best for: Quiet mowing on small to medium yards
Pros
- Brushless motor
- 1-1/4 to 3-3/8 inch cut range
- Full charge in 120 minutes
Cons
- Runtime listed as 30 and 45 minutes
Best for: Small lawns up to 1/3 acre
Pros
- Cuts up to 1/3 acre per charge
- Mulch and rear bagging
- Battery, charger and bag included
Cons
- Brushless motor not listed
- 5 lb, heaviest 16-inch option
The Greenworks 40V 16in Push Lawn Mower, model 25322, is the classic starter mower in this lineup. The listing says it can cut up to 1/3 acre on a fully charged 4.0Ah battery, with the usual note that grass condition and your mowing style change the result. It is described as 35% lighter than steel deck mowers, and a single lever sets the cutting height in 5 positions.
It is a 2-in-1 mower, meaning you can mulch (chop clippings finely and leave them on the lawn to feed it) or collect them in the rear bag. The box includes the mower, a grass collection bag, the 4.0Ah battery, a charger and the owner’s manual, and it carries a 3-year limited tool and battery warranty. The listing does not mention a brushless motor and gives a weight of 37.5 pounds. This mower suits a small, fairly flat yard. If you want a quieter brushless motor at the same deck size, the LMF417 model below is the step up.
Greenworks 40V 16in Push Lawn Mower LMF417 with a Brushless Motor
The second Greenworks 40V 16in Push Lawn Mower, model LMF417, keeps the 16-inch deck but adds a brushless motor. A brushless motor has no small carbon brushes rubbing inside it, which the listing says gives more torque, quieter operation and a longer life. The battery fully charges in 120 minutes.
Runtime is where the listing disagrees with itself: the feature list says up to 30 minutes on the 4.0Ah battery, while the description says up to 45 minutes. It is described for small to medium yards up to 1/2 acre, has push button start, and offers a single lever 5-position height adjustment from 1-1/4 to 3-3/8 inches, plus mulching and rear bagging. At 33.5 pounds it is lighter than the 25322. This model suits a first-time homeowner who wants a light, quiet push mower for a typical suburban lot.
Greenworks 40V 17in Push Lawn Mower for Six Cutting Heights

Greenworks 40V 17in Push Lawn Mower
Best for: Quarter-acre lawns wanting six heights
Pros
- Brushless motor
- 6 cutting heights
- Up to 35 minutes runtime
Cons
- Cutting width listed as 16.14 inches
- Suited to 1/4 acre only
The Greenworks 40V 17in Push Lawn Mower offers up to 35 minutes of runtime on its included 4.0Ah battery and a brushless motor described as 30% quieter than gas mowers. It switches between mulching and bagging, and a single lever sets 6 cutting heights, one more than the 16-inch models.
Note that although the title says 17 inches, the spec sheet lists a cutting width of 16.14 inches, and the listing recommends it for small to medium yards up to 1/4 acre. It has a plastic body and a 3-year tool and battery warranty. This model suits a smaller lawn where you want an extra height setting for fine-tuning. For larger lots, the LMF417’s 1/2 acre suggestion or a self-propelled model is the better fit.
Greenworks 25″ Self-Propelled Dual Blade Mower for Wide Open Lawns
Best for: Bigger lawns wanting a wide self-propelled deck
Pros
- 25-inch dual blade deck
- Self-propelled
- Mulch, bag and leaf collection
Cons
- 76 lb listed weight
- Battery and runtime not specified
The Self-Propelled Dual Blade Brushless Cordless Battery mower, model MO40L515, has the widest deck here at 25 inches. Dual blade means two blades spin under the deck, and self-propelled means the mower drives its own wheels so you only steer and walk. It has push button start and a single lever with 5 positions from 1-1/4 to 3-3/8 inches.
It is a 3-in-1 mower that mulches, rear bags and offers turbo leaf collection, handy in autumn. The listing is thin in places: it does not state which battery or charger is included or how long it runs, and one spec gives a maximum cutting height of 101.6 centimeters, which clashes with the 3-3/8 inch figure. It lists a weight of 76 pounds and a 3-year warranty. The listing calls the deck “lightweight” for compact yards, but a 25-inch self-propelled mower is really aimed at larger, open lawns where fewer passes save time.
Greenworks 40V 16″ Combo Kit with Trimmer and Blower
Greenworks
Greenworks 40V 16" (Push) Cordless Lawn Mower (1/3 Acre) + 12" String Trimmer + Leaf Blower, 4.0Ah + 2.0Ah Batteries and (2) Chargers Included
Price and specifications are read from the Amazon product page and can change.
Greenworks 40V 16″
Best for: First homeowners needing mower, trimmer and blower
Pros
- Mower, 12-inch trimmer and blower
- 0Ah and 2.0Ah batteries
- Two chargers included
Cons
- Push mower, no self-propel
- More gear to store
The Greenworks 40V 16″ combo kit pairs the 16-inch push mower with a 12-inch string trimmer and a leaf blower. The mower matches the 25322 description: up to 1/3 acre on the 4.0Ah battery, 35% lighter than steel deck mowers, 5 height positions, and mulching or rear bagging.
The trimmer uses .065-inch auto-feed line and is described as cutting through weeds up to 1 inch thick, with a 3-year head warranty. The blower is rated at 110 MPH and 390 CFM (CFM is how much air it moves per minute) with cruise control. The kit includes a 4.0Ah and a 2.0Ah battery plus two chargers, and the listing says the 2.0Ah battery charges in 60 minutes. This is the easiest gift for a new homeowner who owns no yard tools yet. If they already have a trimmer and blower, a mower-only model saves storage space.
Greenworks 40V 21″ Brushless Cordless Self-Propelled for Tougher Terrain
Best for: Sloped or bumpy yards needing drive help
Pros
- Rear wheel self-propelled drive
- Steel deck with 7 heights
- Mulch, bag and side discharge
Cons
- Listed weight looks inconsistent
- Wider body needs more storage
The Greenworks 40V 21″ Brushless Cordless mower is self-propelled with rear wheel drive, which the listing says increases traction on tough backyard terrain. It runs up to 45 minutes on the included 5.0Ah battery, has a durable steel deck and a brushless motor, and uses 8-inch front wheels.
A single lever offers 7 height positions, the most in this list, and it is a 3-in-1 mower with rear bag, side discharge and mulching. Side discharge throws clippings out the side, useful when grass is too long to bag. The spec sheet lists a cutting width of 20.28 inches and a weight of 21.7 pounds, which seems low for a steel-deck self-propelled mower, so check the product page. This model suits medium yards with slopes or bumps where pushing gets tiring. For more on driven mowers from the brand, see our guide to the Greenworks self-propelled lawn mower range.
How to Choose the Right Greenworks 40V Cordless Lawn Mower
Start with deck width. The deck is the housing around the blade, and its width is how wide a strip you cut in one pass. A 16- or 17-inch deck is easy to steer around flower beds and fits small lawns; a 21-inch deck cuts more per pass; the 25-inch dual blade model covers open lawns fastest.
Next, decide between push and self-propelled. Push mowers like the three 16- and 17-inch models are lighter and simpler. Self-propelled models such as the 21-inch and 25-inch mowers drive their wheels for you, which helps on hills and larger yards. If you are still comparing push designs in this size class, our look at an 18-inch 40V brushless mower offers another reference point.
Then look at battery and runtime. A 4.0Ah battery is listed at 30 to 45 minutes depending on the model, while the 5.0Ah battery in the 21-inch mower is listed at up to 45 minutes. Bigger lawns may need a second battery. Remember that every 40V battery works across the Greenworks 40V tool family.
Finally, think about extras. The combo kit is ideal if you need a trimmer and blower too. Mulching, bagging, side discharge and leaf collection options vary, so match them to how you like to handle clippings.

FAQ
Which Greenworks mower should I buy for a small yard?
For a small, flat lawn, a 16-inch push model is usually enough. The LMF417 adds a brushless motor, while the 25322 is the simpler option rated for up to 1/3 acre.
What is the difference between push and self-propelled mowers?
You provide all the forward motion on a push mower. A self-propelled mower, like the 21-inch and 25-inch models here, powers its own wheels so you mainly steer, which is easier on slopes and bigger lawns.
Can I use the same battery in other Greenworks tools?
Yes. The listings say Greenworks 40V batteries work with more than 75 Greenworks 40V tools, including trimmers, blowers and chainsaws.
What does 2-in-1 or 3-in-1 mean on a mower?
It lists how the mower handles clippings. 2-in-1 means mulching and bagging. The 3-in-1 models add side discharge (the 21-inch) or turbo leaf collection (the 25-inch).
Is the 40V mower combo kit worth it for a new homeowner?
If you have no yard tools yet, the combo kit gives you a mower, trimmer, blower, two batteries and two chargers in one box, which makes it a practical all-in-one gift.
What warranty do Greenworks 40V mowers have?
Most listings here state a 3-year limited tool and battery warranty, and the 25-inch model lists a 3-year warranty. The combo kit listing names a 3-year warranty on the trimmer head but does not specify the mower terms.
