The Greenworks 25322, also sold as the LM1604 kit, is a 40V 16-inch cordless push mower for small lawns. It includes one 4.0Ah battery and a standard charger, weighs 37.8 pounds, and can mulch or collect clippings. The compact deck and simple controls are its main advantages.
Greenworks claims up to 40 minutes of runtime and promotes the mower for as much as one-third acre, while the same product page also lists one-quarter acre in its specifications. We would use one-quarter acre as the more realistic planning target and leave battery reserve for thick grass or less-than-ideal conditions.

Best yard size for the 25322
This mower fits small, regularly maintained lawns with a practical mowing area around one-quarter acre or less. A simple open yard gives the battery and 16-inch deck the best chance of completing the job efficiently. Hills, thick grass, bagging, frequent turns, and an overgrown first pass all reduce the area covered.
One-third acre is possible under favorable conditions, but a buyer near that size should consider a second compatible battery or a wider mower. A 16-inch deck requires about 25 percent more passes than a 20-inch deck before accounting for overlap.
Runtime and charging
The included 4.0Ah pack is the only battery bay, so the mower stops when that pack is depleted. Greenworks’ up-to-40-minute claim is enough for many compact lawns, but it is not a guarantee. Battery age, temperature, grass density, mowing height, and blade condition all affect runtime.
The standard charger takes about two hours according to the current Greenworks listing. That makes a mid-job recharge impractical. If your lawn regularly takes longer than one charge, a second battery is more useful than waiting.
Greenworks says its 40V batteries work across more than 75 tools, subject to model compatibility. The company also warns that its large 40V 8.0Ah battery does not allow this mower’s battery cover to close. Do not assume every same-voltage pack fits the compartment correctly.
Cutting height and grass types
Five single-lever settings range from 1.25 to 3.375 inches. That covers common residential mowing heights and is taller than many compact corded models, though it does not reach the 4-inch maximum of several full-size cordless mowers.
The plastic deck will not rust and helps keep weight low. The 16-inch blade is suited to maintained grass rather than rough field growth. When grass is tall, raise the deck, mow slowly, and return for a lower second pass instead of forcing a low cut.
Mulching and bagging
The 2-in-1 design supports mulching and rear bagging. It does not provide side discharge. Mulching is efficient when grass is dry and you remove only a small portion of the blade. Bagging is useful near patios or during heavy seed-head growth but increases stops and can reduce battery runtime.
Before buying used or open-box inventory, confirm that the grass bag, frame, mulch plug, battery, charger, safety key, and manual are present. Greenworks gives renewed products a shorter 90-day limited warranty, while new kits list three-year tool and battery coverage.
Our research method
Our reviews are research-based. We compare official specifications, manuals, warranty terms, owner feedback patterns, current availability, and competing products. Unless we specifically say otherwise, the product has not been personally tested by our editorial team.
Handling and storage
At 37.8 pounds, the mower is easy to turn and push on level ground. It is not self-propelled, but a traction system would add weight, cost, and battery use. The folding handle can reduce the storage footprint by up to 70 percent according to Greenworks.
Compact storage is useful in a garage corner or small shed. Remove the battery before cleaning or blade work, brush away dry clippings, and store both mower and battery in a dry location within the temperature limits in the manual.
Greenworks 25322 versus corded mowers
The Greenworks costs more than a compact corded mower but eliminates cable routing. That difference matters most in yards with trees, beds, gates, or lawn sections on multiple sides of the house. A corded mower provides unlimited runtime and avoids eventual battery replacement.
Compare it with the Sun Joe MJ403E for steady corded power or the LawnMaster MEB1114K for the lightest small-yard option. For more deck width and battery capacity, see the Greenworks LME474 review.

Frequently asked questions
Can it mow one-third acre?
Greenworks advertises up to one-third acre but also lists one-quarter acre in the product specifications. Actual coverage varies, so one-quarter acre is the safer target with the included 4.0Ah battery.
Is the mower self-propelled?
No. It is a manual-push mower.
How long does the battery take to charge?
Greenworks lists about 120 minutes with the included charger.
Can it side discharge?
No. This model is designed for mulching or rear bagging.
Will any Greenworks 40V battery fit?
Compatible 40V packs power the mower, but Greenworks specifically notes that the 8.0Ah pack prevents the battery cover from closing. Confirm physical fit and current compatibility.
Verdict
The Greenworks 25322 remains a good small-yard mower for buyers who value low weight and cordless movement. Its 16-inch deck, single battery, and brushed motor set clear limits. Choose it for roughly one-quarter acre or less; choose a wider dual-battery mower when speed, hills, or thick grass matter more.
