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

The Worx 40V 21-inch cordless lawn mower is a walk-behind, self-propelled machine built for yards up to a half-acre. Powered by two 20V 5.0Ah PowerShare Pro batteries running together to deliver 40V, it eliminates the need for gas, pull cords, and extension cords. It suits homeowners who want a motorized drive system to ease yard maintenance without the maintenance chores of gas engines.

Its drive system features variable speed settings reaching up to 3.7 MPH, allowing you to match the pace to your stride. Under the deck, a Brushless Motor 2.0 works alongside IntelliCut technology. Patented sensors automatically ramp up blade speed when hitting dense, overgrown patches, then throttle back in lighter grass to conserve battery runtime. The AeroDeck vented design increases internal airflow, helping keep the deck clear of clumps while maximizing clippings packed into the collection bag.

Flexibility and convenience are clear priorities across the build. You can switch between bagging, mulching with the included plug, or rear side-discharging. A single lever shifts the 21-inch deck through seven distinct cutting heights ranging from 1.5 to 4 inches, while an onboard battery gauge displays charge levels during operation. When the job is done, the handle fully collapses so the mower can stand vertically against a wall.

As a cordless unit sized for up to 1/2 acre, it is not built for sprawling multi-acre properties without swapping or recharging packs. Operating a dual-battery platform also means keeping track of two batteries, though the package includes a 4.0A dual charger to power both simultaneously.

Verdict: This self-propelled mower is a great match for suburban homeowners with up to a half-acre lawn who want versatile cutting modes and adjustable walking speeds. The included dual-port charger, paired batteries, and space-saving vertical storage make it a practical, complete setup right out of the box.
