Greenworks 40V 16in Push Lawn Mower, 4.0 Ah Battery and Charger

This is a battery-powered push mower built for homeowners with small to medium yards, up to about half an acre. It trades the noise, fumes, and maintenance of a gas engine for the simplicity of a 40V lithium-ion system. If you want to mow without mixing fuel or yanking a pull cord, this machine is designed around that goal.

The brushless motor is one of the most meaningful features here. Brushless designs produce more torque than brushed alternatives and run more quietly, which matters if you have neighbors nearby or prefer to mow early in the morning. The 4.0Ah battery charges fully in 120 minutes and provides up to 30 minutes of runtime, which is a reasonable window for yards in the half-acre range. The battery also works across 75-plus other Greenworks 40V tools, so if you already own a compatible trimmer or blower, or plan to buy one, you can share the same pack across your whole outdoor kit.

The 16-inch cutting deck is lighter than the wider decks found on larger mowers, and that reduced weight translates directly to easier steering around flower beds, fences, and tight corners. Height adjustment is handled with a single lever that moves through five positions, covering a range from 1-1/4 inches to 3-3/8 inches. The 2-in-1 setup supports both mulching and rear bagging, so you can choose whether to return clippings to the lawn or collect them for disposal. Starting the mower is a simple push-button operation, no priming or choke involved.

A few limits are worth knowing before you buy. The 30-minute runtime is enough for many small yards, but if your property runs close to half an acre or has thick, slow-going grass, you may need to pause and recharge before finishing. The 16-inch deck is efficient in tight spaces but means more passes on open stretches compared to wider decks. The listing does not mention a side-discharge option, so clipping management is limited to the two included modes. The cutting height tops out at 3-3/8 inches, which may not suit everyone's preference for taller grass.

Verdict: This mower fits best with homeowners who have a yard up to half an acre and want a low-maintenance, cord-free setup they can start instantly. The brushless motor, shared 40V battery platform, and included 3-year warranty on both the tool and battery make it a solid, practical choice for that audience.
