Greenworks 40V 25322 16-Inch Push Lawn Mower Review

The mower's strengths all come back to one idea: it is easy to live with on a small lot. Buyers on Amazon most often praise its performance, and the weight is the next thing they mention, with many describing it as light enough to push with one arm. One customer compares pushing it to pushing a vacuum cleaner. At 37.5 lb that makes sense, and it is what lets you swing the machine around a flower bed or pivot at the end of a run without wrestling it.

Quiet, gas-free and simple to start

Noise is the third thing buyers single out, and the spec sheet advertises quiet, gas-free operation with no fumes and no pull start. You press a button and go. Assembly is straightforward, and the cutting height moves through five positions on a single adjustment, so changing the deck height between seasons takes a moment rather than a wrench.

Built for tight corners

The 16-inch deck is narrow, and on a small lawn that is a feature rather than a flaw. The mower's intended use is maintaining a suburban lawn and navigating tricky corners, and the short deck plus the low weight are exactly how it does that. It slips between shrubs and along fence lines where a wide machine would need several attempts.

One battery across the yard

The 40V battery is compatible with Greenworks 40V trimmers, blowers and chainsaws. If you already own those tools, or plan to, the pack you get with the mower keeps working after the mowing is done, and a spare you buy for the mower serves the rest of the shed.

Mulch or bag, the two modes most small lawns need

The 25322 is a 2-in-1 machine: it mulches clippings back into the turf or collects them in a bag. Those are the two modes most owners of a small lawn actually use, and having both covers the weekly cut and the occasional cleanup after the grass has grown a little too long.

The limits are real and worth knowing before you buy, because most of them are built into the design rather than fixable with a setting. None of them is a defect. They are the trade-offs that come with a light, narrow, battery-powered push mower.

You do all the pushing

This is a push walk-behind with manual operation and no self-propel. On flat ground that is fine. On a slope, or across a long run, your arms and legs do the work the whole time, and the mower gives you nothing back.

A narrow deck means more passes

The cutting width is 15.67 inches.

The cutting height tops out at 3.75 inches

The deck adjusts from 1.25 to 3.75 inches across its five positions. That ceiling is the constraint to think about: lawns kept long, or grass types that want to stand tall, will be cut shorter than you may want. For a lawn mowed regularly at a normal height, the range is plenty.

No side discharge

The mower mulches or bags, and that is all. If you are used to a three-mode machine and rely on side discharge to throw clippings out the side, this one does not do it.

Battery life divides buyers

Battery life is the topic buyers on Amazon raise most, and their verdict is split: some say it lasts a long time, others say it dies quickly. Treat that as the number to plan around, and expect your own result to depend on how thick and wet the grass is.

Tall, thick or wet grass bogs it down

Power drops when the mower meets heavy going, and it can stall. This is a machine that rewards regular mowing and punishes catch-up mowing. Let the grass get long and you will feel the difference immediately.

A plastic build and a bouncy deck

The deck and body are plastic, and one buyer notes how plastic it feels. That is the price of the low weight. The same lightness means the deck bounces over rough ground instead of tracking it, which can leave patches on uneven terrain.

Mixed feelings on value

Value for money is the other divided topic among buyers on Amazon: some find it worth it, others do not. The light weight, quiet motor and push-button start are what justify its price, and whether that adds up for you depends on how well the rest of the list matches your yard.

The 16-inch deck is the number that shapes your day: it means more passes than a wider mower, but it also means the machine turns easily and fits into corners. The 37.5 lb weight is what makes those extra passes bearable, since you are pushing very little mass. The height range tells you the mower is built for a lawn that is kept in check, not for bringing tall grass back under control. And the 35-minute rated run time sets the size of lawn this mower is comfortable on: a small one, cut in a single session.

The 25322 suits a yard when the rated 35-minute run time, the 15.67-inch cutting width and the 3.75-inch height ceiling all match how you mow.

Runtime against lawn size

The rated average battery life is 35 minutes. That is the window you get per charge, and it is the reason this mower belongs on a small lawn. Buyers on Amazon are divided on whether the battery lasts, so the honest approach is to plan for the rated figure and treat anything longer as a bonus. If your lawn takes close to that window, a second battery turns a stressful cut into a relaxed one.

Deck width against walking

A 15.67-inch cutting width covers less ground per pass than a wider deck, so a given lawn takes more laps. On a compact lot the difference is a few extra minutes. On a large one it is the difference between a chore and an afternoon.

Height range against your grass

With a maximum of 3.75 inches, the mower cannot leave a tall lawn tall. If you like your grass on the long side, or your grass type wants to stand up, check that ceiling against how you actually mow before you commit.

Amazon's summary of its customer reviews describes a mower that people find effective and easy to handle, with the reservations concentrated in two places: the battery and the value.

The praise

Performance draws the most positive mentions by a wide margin, followed by weight, noise level, ease of use, effectiveness and size.

The complaints

Battery life is the most-mentioned topic overall and the one buyers are split on. Value for money is split too. Beyond those, the pattern in owner feedback elsewhere is consistent: sudden power loss when the mower hits thick grass, a battery that can be awkward to seat and remove, a plastic feel to the build, and uncut strips between passes when you do not overlap deliberately. The plastic safety key can also be fiddly to replace.

What the star spread says

The large majority of ratings are four or five stars, with a small but visible tail of one-star ratings. That shape fits a product that delights the buyer whose yard matches it and frustrates the buyer whose yard does not. The mower is not inconsistent so much as narrow in what it is good at.

Most of the frustration owners describe comes from asking the mower to do something its design does not support. A few habits keep it in its comfort zone.

Mow on a schedule, not on a rescue mission

The mower bogs down in tall, thick or wet grass.

Overlap your strips

One buyer reports uncut strips between passes.

Check the battery before you blame the mower

Keep it on the flat

The light plastic deck bounces on rough ground and leaves patches.
