As an Amazon Associate we earn from qualifying purchases.
Searching for the best Greenworks 40V 16in push lawn mower? The direct answer: this is a manual, battery-powered push mower with a stated cutting width of 15.67 inches, five height positions between 1.25 and 3.75 inches, and one 4.0Ah battery and charger in the box. The listing says it cuts up to one-third of an acre on a fully charged battery, but it gives no test conditions for that figure. This review covers only this one ASIN and uses listing data stored on 2026-10-11.
Quick answer
- The listing describes a manual, battery-powered push mower. It is not self-propelled.
- The box includes one 4.0Ah battery, one battery charger, a grass collection bag and the owner’s manual, according to the listing.
- The stated cutting width is 15.67 inches, and the height range runs from 1.25 to 3.75 inches across five positions.
- The listing gives an average battery life of 35 minutes without test conditions. Plan your mowing with the one-third rule from university guidance rather than that single number.

Cut height and the one-third rule
The listing sets the range you can choose: a minimum of 1.25 inches and a maximum of 3.75 inches. Illinois Extension states that for most lawns, a mowing height between 2½ to three inches is suggested, and that band sits inside the listing’s range. The same extension page gives lower ranges for some warm-season grasses, including bermudagrass at 1 to 2 inches, so the 1.25-inch minimum matters mainly for those lawns.
The one-third rule is the constraint that matters most. Illinois Extension advises that you not remove more than one-third of the grass leaf in a single cutting. You can turn that rule around for planning. If you want to leave the grass at a set height, mow when it has grown to 1.5 times that height. The table below applies the rule to the listing’s minimum, maximum and a few middle settings.
| Cut height (inches) | Mow when grass reaches (inches) |
|---|---|
| 1.25 (listing minimum) | 1.875 |
| 2.5 | 3.75 |
| 3.0 | 4.5 |
| 3.75 (listing maximum) | 5.625 |
The formula is mow-when height equals cut height multiplied by 1.5. If you remove one-third of the full height, the remaining two-thirds equals the cut height, so the full height equals the cut height divided by two-thirds. The figures are arithmetic from the listing’s range and the university rule. They describe planning, not how this mower performs.
What one-third of an acre means in feet
The listing’s coverage figure is one-third of an acre. One acre is 43,560 square feet, so one-third of an acre is 14,520 square feet. The stated cutting width of 15.67 inches is about 1.31 feet. Dividing the area by the cutting width gives the length of straight cutting path with no overlap: 14,520 divided by 1.31 is about 11,100 feet, or roughly 2.1 miles.
Real mowing overlaps each pass and includes turns at the edges, so a real lawn needs more distance than that straight-line figure. The calculation shows the scale of the listing’s claim. It does not show runtime, because the listing does not say how long a pass takes or how the 35-minute average was measured.
The battery can be checked the same way. A 40V battery rated at 4.0Ah has a nominal energy of 160 watt-hours, which is 40 volts multiplied by 4.0 amp-hours. That number is arithmetic from two listing values. It is not a measured runtime, and it does not tell you how much grass one charge covers at your height. For background on what voltage and amp-hour ratings mean on mower batteries, see our guide to lawn mower battery voltage and amps.
Who it suits
The listing supports a specific reading of who this mower is for. Four groups fit it best.
- A homeowner whose lawn is at or under the one-third acre the listing states, and who wants to finish the lawn on one fully charged battery.
- Someone who wants a push mower without fuel, a gas engine or a pull cord. The listing’s highlight says gas-free operation eliminates fumes and pull starts, and it lists a push-button start.
- An existing Greenworks 40V owner. The listing says the battery works with 75+ Greenworks 40V tools, so one battery platform can serve more than one job. Confirm the fit for your own battery in the owner’s manual before you buy.
- A person who wants mulching and bagging on one machine. The listing describes a 2-in-1 system with mulch and rear bagging, and a grass collection bag is included.
Lawns in the 2½ to 3 inch cutting band suggested by Illinois Extension can be served by the middle of this mower’s range. If the lawn is bigger, or you want a cord instead of a battery, a corded model may suit better. See our guide to the Greenworks 10 Amp 16-inch corded mower for a corded option.
Skip it if
- You need a self-propelled machine. The listing gives the operation mode as manual, so you move the mower across the whole lawn yourself.
- Your lawn is larger than the listing’s one-third acre figure. The included battery is one 4.0Ah pack, and the listing does not say whether a second battery is included or sold separately.
- You need a cut below 1.25 inches or above 3.75 inches. The listing sets those limits, and the five individual positions are not listed.
- You need a cutting width wider than 15.67 inches to finish a large open area sooner.
- Your storage space is tight. The listing’s product dimensions are 50.79 inches deep, 18.9 inches wide and 38.98 inches high. Check those against your shed, garage or closet before ordering.
- You plan to mow steep slopes often. The listing gives a weight of 37.5 pounds, and Iowa State University Extension advises mowing across a slope rather than up and down with a walk-behind mower.
If a self-propelled Greenworks 40V model fits your lawn better, compare the options in our guide to the best Greenworks 40V electric lawn mower before you decide.
Buying checklist
- Compare your lawn area with the listing’s one-third acre figure, and keep the 15.67-inch cutting width in mind when you estimate passes.
- Check your storage space against the stated dimensions: 50.79 inches deep, 18.9 inches wide and 38.98 inches high.
- Write down the cutting height you want, then confirm it falls between 1.25 and 3.75 inches.
- If you already own Greenworks 40V tools, confirm the battery fit in the owner’s manual rather than assuming it.
- Plan for charge time separately, because the listing does not state one.
Mistakes to avoid
- Removing more than one-third of the grass height in one cut. Illinois Extension warns against it, and a longer cut setting does not change that rule.
- Mowing wet grass. Illinois Extension says it is never advisable to mow when the grass is wet, and it notes that mulching mowers lose efficiency on wet turf.
- Cutting too short to save a trip. Illinois Extension says not to cut so short that you scalp the lawn, and it advises keeping the first and last mow of the year only slightly shorter.
- Assuming the battery fits every tool in a family. The listing’s 75+ tool claim is the listing’s own statement, so confirm the fit for the tool you own.
What the listing does not say
Several details that matter for a buying decision are missing from the listing. This post leaves them open rather than filling them with guesses.
- Runtime conditions. The listing gives 35 minutes as battery average life. It does not say the grass height, grass type, load or temperature behind that figure.
- Charge time. The listing does not state how long the included 4.0Ah battery takes to charge.
- Charger specifications. The listing names the charger as included, but it gives no separate charger details.
- Motor and blade. The listing does not state the motor type, blade size or blade material.
- Height settings. It gives the minimum, the maximum and a count of five positions, but not the individual settings.
- Mulching performance. The listing names mulch and rear bagging, but it does not say how fine the clippings are or how well the mulching works on tall grass.
- Comparison basis. The listing says the mower is 35% lighter than steel deck mowers, but it does not give the weight of the steel deck model it compares against.
- Warranty terms. It gives the 3-year limited tool and battery warranty wording, but not the exclusions or the claim steps.
Where this post repeats a listing claim, it labels the claim as the listing’s own statement. It does not present that claim as an independently checked fact.
How we chose
This post covers one product: Amazon ASIN B00BBQVL5U, Greenworks model 25322. It came from our stored product set because its listing includes the figures a push-mower buyer needs most: cutting width, height range, weight, battery and charger inclusion, and operation mode. This post does not compare it with other mowers and makes no ranking claim.
The product data comes from a stored scan of the listing last checked on 2026-10-11. We left out prices, star ratings, review counts and seller badges, because none of them help a reader judge the mower’s stated specifications. The two university pages were opened on 2026-10-22. One of them is an Iowa State article dated April 9, 1999, and it is used only for general safety advice, not for product facts.
What we could not verify
- The 35-minute average battery life and the one-third-acre coverage figure. Neither comes with a stated test method.
- Warranty terms beyond the listing’s wording. The sources we opened do not cover this model’s warranty terms.
- Manufacturer specifications for model 25322. The manufacturer’s product page did not open for us, so the table reflects the listing only.
- Motor type, blade size and blade material. The listing does not state them, and the sources we opened do not cover this model’s parts.
- Charge time, and how many charges a typical lawn needs at the cut height you choose.
- How the Iowa State advice applies today. The article is dated April 9, 1999, and the page itself notes that the information may not be the most current.
FAQ
Does the Greenworks 40V 16in push mower include a battery and charger?
The listing says it includes one 4.0Ah battery and one battery charger, along with a grass collection bag and an owner’s manual. It names only one battery, and it does not say whether a second battery is sold separately.
How long does the battery last on this mower?
The listing gives an average battery life of 35 minutes. It does not state the grass height, grass type or load behind that figure, so treat it as a rough planning number rather than a guarantee.
What cutting heights does this mower offer?
The listing gives a minimum of 1.25 inches and a maximum of 3.75 inches across five positions. It does not list the five individual settings. Illinois Extension suggests a height of 2½ to 3 inches for most lawns, which falls inside that range.
Is this mower self-propelled?
No. The listing gives the operation mode as manual, so the mower moves only when you push it.
Does the battery work with other Greenworks tools?
The listing says the battery works with 75+ Greenworks 40V tools, including trimmers, blowers and chainsaws. Check the listing for the specific tool, or its owner’s manual, before you assume a fit.
What safety steps apply when using a push mower like this one?
Iowa State University Extension advises removing branches, stones and toys before mowing, keeping hands and feet away from the blade while it runs, mowing across slopes and pushing rather than pulling. Keep children and pets at a safe distance. That article is dated 1999, so also follow the owner’s manual that comes with your unit.
Bottom line
Buy this mower only if your lawn is at or below the listing’s one-third acre figure and you are comfortable pushing a 37.5-pound machine on one 4.0Ah battery. If you need self-propulsion, a wider cut or a second battery in the box, look at other models first.
