The Worx Cordless Lawn Mower, cataloged under model number worx wg752, serves as the brand’s primary wide-deck push machine for properties up to a half acre. Powered by two 20V 5.0Ah PowerShare Pro batteries that combine to deliver 40V of brushless cutting muscle, this model targets homeowners who desire the broad cutting path of a traditional walk-behind without the hassle of fuel. Worx equips the machine with aerodeck technology, a vented design that boosts air volume inside the cutting chamber. This heightened airflow lifts turf blades for a uniform cut, prevents clipping clogs underneath the deck, and optimizes grass collection into the rear bag compared to previous designs like the WG751. Power delivery is managed by a Brushless Motor 2.0, providing 40 percent more power and 10 percent longer runtime than first-generation brushless motors.

Everyday operation centers on the brand’s intelligent sensor array known as Intellicut technology. This system continually monitors resistance on the cutting blade, automatically increasing cutting speed to push through thick patches of turf and dialing it back in lighter grass to conserve battery power. The worx 21 inch lawn mower provides full 3-in-1 clipping versatility out of the box, allowing users to mulch clippings back into the soil, bag them into the collection bag, or discharge them through the included rear side-discharge chute. Height adjustments are handled through a single seven-position lever spanning from 1.5 inches to 4 inches, while an onboard charge indicator provides real-time battery status updates.

This push mower suits property owners with open, relatively flat half-acre yards who want to finish mowing in fewer passes without maintaining a gas engine. At 55.6 pounds, it provides steady turf contact and clean tracking across level terrain. However, because it relies completely on physical effort rather than powered drive wheels, operators managing sloped terrain or steep inclines will find the self-propelled version a more practical match.

Engineered on the same broad 21-inch cutting deck as its push counterpart, the self-propelled Worx Cordless Lawn Mower, designated as model worx wg760, is designed to reduce physical strain on lawns up to a half acre. It combines a 40V power plant using two 20V 5.0Ah PowerShare Pro batteries with a variable-speed rear drive that propels the mower forward at user-selected speeds up to 3.7 miles per hour. This motorized drive allows operators to guide the machine comfortably up inclines and across rough ground without pushing against the weight of the deck.

Beneath the deck, the machine features the same aerodeck vented construction found on the brand’s premium push model. By moving higher air volume through the cutting chamber, the vented housing channels grass clippings smoothly into the included collection bag and resists clipping clumping during damp morning cuts. The worx wg760 utilizes a Brushless Motor 2.0 alongside Intellicut technology, automatically raising motor torque when tall turf is detected. The mower supports 3-in-1 cutting options with a mulch plug, rear side-discharge chute, and collection bag included, complemented by single-lever height adjustment between 1.5 inches and 4 inches across seven settings. The handle folds completely for compact vertical storage in tight garages, and Worx backs the unit with a 3-year limited warranty.

This self-propelled worx 40v lawn mower represents the premier choice for homeowners with sloped, rolling, or uneven half-acre lawns who want wide-deck efficiency without manual pushing. The variable-speed drive takes over the hard uphill work, making lawn care accessible for users of varying physical strength. The manufacturer listing does not specify the exact assembled weight for this model, and homeowners with small, flat lawns may not require the added mechanical drive system.

For yards where a large 21-inch deck feels cumbersome around garden beds and tight patio corners, the Worx Cordless Lawn Mower with model code worx wg745 offers an agile intermediate solution. Featuring a 17-inch deck that delivers an effective 16-inch cutting width, this push mower is scaled specifically for yards up to a quarter acre. It runs on two included 20V 4.0Ah PowerShare batteries recharged via an included dual-port charger, delivering 40V cordless cutting power inside a lightweight chassis that weighs just 39.7 pounds, or 40 pounds fully assembled.

Despite its more compact footprint, the worx wg745 utilizes an efficient Brushless Motor 2.0 that provides 40 percent higher cutting power, 10 percent longer runtime, and ten times longer motor life than first-generation brushless motors. It incorporates Intellicut technology to adjust cutting speed automatically based on turf density, conserving runtime when cutting less demanding areas. An onboard battery charge display keeps power levels clearly visible during use. The deck features a cut-to-edge profile that lets the blade cut closely alongside fences, flower beds, and garden borders to reduce secondary line trimming.

This machine is an excellent match for homeowners with quarter-acre suburban lots who value easy maneuvering and simple storage over maximum cutting width. Its sub-40-pound weight makes it easy to guide through tight landscape corridors and lift over steps. However, it functions as a 2-in-1 mower supporting bagging and mulching only, meaning users who require side-discharge or manage broad half-acre turf will prefer the larger 21-inch models.

Homeowners with compact townhome yards, small urban gardens, or tight storage spaces will appreciate the focused utility of the Worx Cordless Lawn Mower, referenced as model worx wg733.1. As the lightest model in the Worx lineup at just 21.7 pounds, this mower features a 14-inch deck with a 13-inch cutting width. Rather than using dual batteries, this push mower operates on a single included 20V 5.0Ah PowerShare Pro battery, engineered to cover lawns up to 3,200 square feet on a single charge.

The compact frame of the worx wg733.1 is paired with an efficient brushless motor designed to optimize energy output from its single battery pack. Worx integrates its cut-to-edge engineering into this slim deck profile, allowing users to cut flush against garden borders, fences, and sidewalks to minimize weed trimming. The mower provides 2-in-1 capability for switching between mulching and rear bagging, supported by a one-bushel collection bag for fewer emptying pauses. A single-lever adjustment system provides six height positions spanning 1 inch to 3 inches, adapting easily to seasonal grass growth.

This featherweight mower is ideal for townhome residents, seniors, and homeowners with small turf areas under 3,200 square feet where lifting and pushing a heavier mower causes strain. The 21.7-pound weight makes carrying the unit through gates or hanging it in storage effortless. However, with its narrow 13-inch cutting path and single 20V battery supply, it is not designed to tackle larger suburban properties.

The WORX Cordless Lawn Mower, model number WG735, is a compact 14-inch push mower designed for lots up to an eighth of an acre. Weighing 27.7 pounds, this walk-behind mower provides a 14-inch cutting width housed in a slender frame that maneuvers smoothly through narrow spaces. It is powered by an included 20V 4.0Ah battery, backed by a brushless motor and IntelliCut torque sensors that automatically dial up power in tall grass and dial it back in light turf.

Clipping collection on the WG735 is handled by an airflow-optimized deck that channels clippings forcefully into an included one-bushel collection bag for thorough grass pickup. The machine provides 2-in-1 operation, supporting both rear bagging and mulching modes. A standout feature is its six-position single-lever height adjustment, which ranges from 0.8 inches to 3.0 inches. This provides the lowest minimum cutting height among the reviewed Worx models, making it suitable for turf varieties that thrive when kept closely cropped. The slim deck also incorporates cut-to-edge engineering to trim cleanly along landscape borders.

This model suits homeowners managing small eighth-acre lawns who want the flexibility to cut their turf under an inch while retaining nimble handling around obstacles. Its light weight makes turning around patio furniture and flower beds simple. However, because it is built for small yards up to an eighth of an acre and omits a side-discharge chute, property owners managing quarter-acre or half-acre turf will need a wider multi-battery model.

The WORX Cordless Lawn Mower, model number worx wg779, provides dual-battery 40V power inside a compact 14-inch push frame tailored for eighth-acre suburban yards. The mower runs on two included 20V 4.0Ah PowerShare batteries, accompanied by a dual-port charger that recharges both batteries simultaneously. Starting the unit requires only a push-button start and bail handle pull, eliminating the hard physical starting common with gas equipment.

A central feature of the worx wg779 is its quiet operation, generating a low sound level of 87.8 decibels to prevent noise complaints during early morning yard work. Weighing 29.1 pounds, the mower includes an integrated carry handle on the motor deck along with fully collapsible handles for compact vertical storage. Cutting performance is guided by patented Intellicut sensors that automatically adjust blade velocity to grass density, while a single lever shifts the deck across six cutting heights between 1.5 inches and 3.5 inches. The included 0.85-bushel collection bag features a full-bag indicator flap to signal when dumping is needed, and the included mulch plug lets users return clippings to the turf.

This model is an excellent match for homeowners with small yards up to an eighth of an acre who want quiet cutting and the sustained power of a 40V dual-battery system. It rolls easily over small slopes and stores away in tight spaces. With its 14-inch deck and 0.85-bushel bag, however, it requires significantly more passes and bag empties on midsize or large yards than the 17-inch or 21-inch alternatives.
