Worx Cordless Lawn Mower, 40V 21" 3-in-1 Grass Mower for 1/2 Acre,

The WORX 40V 21-inch Cordless Lawn Mower is an electric walk-behind mower built for homeowners maintaining yards up to a half-acre. Powered by two 20V 5.0Ah PowerShare Pro batteries running simultaneously, it provides cordless freedom without gas, oil, or pull cords. The self-propelled drive system lets you dial in a walking speed up to 3.7 MPH, making regular lawn care significantly less tiring across moderate-sized properties.

Cutting performance centers on a Brushless Motor 2.0 that provides 40% more power and 10% longer runtime compared to first-generation brushless motors. It works alongside IntelliCut technology, which uses built-in sensors to automatically raise blade speed in thick patches and throttle down in lighter grass to conserve battery power. Meanwhile, the AeroDeck vented cutting deck keeps air circulating to prevent grass clumping, improve cut quality, and fill the collection bag efficiently.

Switching between cutting methods is straightforward with 3-in-1 functionality. You can bag clippings with the included collection bag, finely chop them using the mulch plug, or direct them outward with the rear side-discharge chute. Setting your grass length is equally quick using a single 7-position lever that adjusts cutting heights from 1.5 to 4 inches, while an onboard indicator keeps you updated on remaining battery charge.

Keep in mind that this mower is specifically intended for properties up to 1/2 acre or less, so larger properties may exceed the runtime provided by the included pair of 5.0Ah batteries. It also relies on running two batteries at once, meaning you will need to keep both packs charged using the included 4.0A dual charger. Once mowing is done, the fully collapsible handle allows the unit to store vertically to save floor space.

Verdict: This WORX 40V mower is a well-equipped option for anyone with up to a half-acre of grass who wants the ease of a self-propelled drive and versatile 3-in-1 cutting options. It is especially appealing if you already own or plan to use other tools from the WORX PowerShare battery system.
