Check Price on Amazon

The WORX Nitro WG752 is a masterclass in engineering for the cordless mower space. Its AeroDeck technology forces more air through the cutting chamber, which keeps clippings moving and prevents clogging even in damp grass—a real pain point with lower-end models. The 21-inch deck paired with two 20V 5.0Ah PowerShare Pro batteries gives you a genuine 40V system that can handle a half-acre lot on a single charge, according to real users who report finishing their yard with battery remaining.

The IntelliCut sensor system is the standout feature here: it automatically ramps up blade speed when the mower senses thicker turf and slows back down in lighter patches. This active torque management means you’re not wasting battery spinning at max RPM all the time. Owners consistently praise the instant push-button start, the quiet operation that lets them mow early without disturbing neighbors, and the 7-position single-lever height adjustment that goes from 1.5 to 4 inches.

At roughly 55 pounds it’s not the lightest push mower on this list, but the integrated handle makes it easy to fold upright for storage. Some users noted that replacement blades were scarce at launch, though that typically normalizes as the product matures. The 3-in-1 functionality (mulch, bag, rear side-discharge) covers all the bases, and the dual charger fills both batteries simultaneously—a nice time-saver.

The EGO Power+ LM2112 delivers 6.0 ft-lbs of cutting torque—a figure that puts it in direct competition with gas mowers. That torque comes from the 56V ARC Lithium battery, which EGO has refined over several generations to maintain voltage under load better than many competitors. Users consistently report that this mower glides through St. Augustine and thick Bermuda grass without bogging down, a testament to the high-efficiency brushless motor and the 21-inch stamped steel deck.

The IPX4 weather-resistant construction is a meaningful detail for anyone who stores their mower in a shed or has to mow through morning dew. The 7-position height adjustment (1.5 to 4 inches) uses a single lever, and the folding handles with adjustable height accommodate taller operators. LED headlights are bright enough for low-light mowing sessions. Owners love the quiet operation—one reviewer noted they can listen to a podcast while mowing—and the vibration-dampened handle reduces fatigue on longer jobs.

Runtime with the included 4.0Ah battery clocks around 35 minutes, which is adequate for a quarter-acre lawn but may need a second battery for half-acre properties. A few users reported battery failures after extended use, but EGO’s warranty service was widely praised for fast replacements. The mower is relatively lightweight at under 70 pounds for its class, making it easy to push and turn.

Westinghouse enters the cordless mower arena with a compelling proposition: a brushless 40V system that spins the steel blade at up to 3100 RPM, all while keeping the weight at a highly manageable 36 pounds. That RPM figure is significant—it’s high enough to shear through thick grass without stalling, something lower-voltage mowers can’t claim. The 18-inch deck strikes a nice balance between cutting width and maneuverability, particularly for yards with tight flower beds or narrow gates.

The dual 4.0Ah batteries (which are actually two 20V packs working in series to deliver 40V) provide enough runtime for a typical quarter-acre lot, and the 4A dual charger means you can replenish both packs simultaneously. An unexpected bonus is that the batteries also fit DeWalt 20V MAX tools, giving you cross-platform compatibility if you already own DeWalt gear. The 2-in-1 mulching/bagging system works well, with a 13-gallon bag that reduces trips to the compost pile.

The biggest gripe from users centers on battery life inconsistency. While some report finishing a half-acre on one charge, others note the batteries last only 10–15 minutes under heavy load—a variance that may reflect differences in grass density or cutting height. The 6-position height adjustment (not the 7-position found on some competitors) has a maximum cutting height that some users found too low for their taste. Assembly is straightforward, though the included manual relies heavily on diagrams.

The Greenworks 80V line sits at the top of the voltage pyramid for consumer cordless mowers, and the MO80L415 model delivers on that promise. The 80V 4.0Ah battery (rated for up to half an acre per charge) feeds a brushless motor that drives a 21-inch stamped steel deck with authority. Users consistently report that this mower handles thick, damp grass without the blade bogging down—a capability that typically requires a gas engine. The 4-in-1 versatility (mulch, bag, side-discharge, turbo leaf pickup) is genuinely useful; the turbo mode opens the rear door wider to suck up fallen leaves in fall.

The LED headlight is a practical touch for early-morning or evening mowing, and the folding aluminum handles reduce storage footprint by about 70%. The 7-position single-lever height adjustment covers 1.38 to 3.75 inches. Unlike some competitors’ plastic decks, the steel construction here adds durability and weight (68 pounds), which helps the mower stay planted on uneven ground. The 4-year tool and 4-year battery warranty is among the best in the industry, reflecting Greenworks’ confidence in their battery chemistry.

The most common complaint involves battery longevity: several users reported the original 4.0Ah battery failing after two seasons, and replacements are costly. The mower itself is hefty, and without self-propulsion, pushing it on slopes requires some effort. The handle height is not adjustable, which shorter or taller operators may find less comfortable. But for raw cutting power and a comprehensive tool ecosystem (75+ compatible tools), the Greenworks 80V is hard to beat.

The NovorikX Obsidian Series brings a 60V platform and a 1200W brushless motor together with a variable-speed self-propelled drive that adjusts from 0.9 to 3.6 MPH. This means you can dial in your walking pace on flat ground and then crank up the speed on slopes without breaking your stride. The 5.0Ah lithium battery delivers up to 65 minutes of runtime—enough for half an acre in most conditions—and the 21-inch steel deck covers ground efficiently. The 3-year tool warranty and 2-year battery warranty provide solid backup.

What sets this mower apart is the 26-position height adjustment range (1.3 to 3.8 inches). That’s significantly more granular than the standard 7-position lever, allowing you to fine-tune the cut to within a fraction of an inch. The self-propelled system uses a handlebar-mounted control, and the mower includes bright LED headlights. Users transitioning from gas mowers particularly appreciate the instant start and the significant reduction in mowing time—one reviewer noted their lawn time was cut in half.

A few early adopters reported issues with the handle locking mechanism causing the mower to stop intermittently. NovorikX’s customer service appears responsive, sending replacement units when needed. The mower is on the heavier side (66 pounds), but the self-propelled drive largely negates that. Some users note that while the mower is quieter than gas, it’s not whisper-quiet like some lower-voltage push models.

The Honda HRX-BE is the battery-powered mower that gas loyalists have been waiting for. It’s built on the same platform as the legendary HRX gas mower, meaning you get the same 21-inch steel deck, the same MicroCut twin-blade system that produces four cutting surfaces, and the same 4-in-1 Versamow system that lets you mulch, bag, discharge, or leaf-shred without swapping attachments. The 12 AH lithium-ion battery is massive, and the dual-battery bay allows you to install a second battery (sold separately) for extended runtime—the mower auto-switches between bays seamlessly.

The cut quality is exceptional. The MicroCut system produces clippings so fine they virtually disappear into the lawn, returning nutrients without leaving clumps. The e-Select Drive electric transmission offers fully variable speed control from 0 to 4 MPH via a touch button, giving you precise pacing. The 7-position dual-lever height adjustment covers 0.75 to 4 inches—the lower end is rare among battery mowers and critical for Bermuda grass owners who want a tight, putting-green finish. The 5-year residential warranty is the best in the category.

The biggest hurdle is the price, which lands in premium territory. The included 2A charger is slow—a full charge takes around 6 hours, so an overnight charge is the normal routine. The grass bag is 2.2 bushels, adequate but not huge. Some users reported defects out of the box (self-propulsion not engaging), which is disappointing at this price point, though Honda’s service network is robust. For those who want Honda reliability without the gas, this is the mower.

The Greenworks 40V Combo Kit bundles the 20-inch mower with a 500 CFM / 120 MPH axial leaf blower and a 12-inch string trimmer/edger, making it a true starter kit for anyone building out a cordless yard-care arsenal. The mower itself features a durable steel deck, a 3-in-1 design (rear bag, side discharge, mulching), and a single-lever 7-position height adjustment from 35mm to 95mm. The 40V 5Ah battery included with the mower provides enough runtime for a quarter-acre lawn, while the two additional 2Ah batteries power the blower and trimmer.

The blower’s turbo button is genuinely effective for moving heavy wet leaves and debris, and the trimmer’s 90-degree pivoting head makes edging along driveways and walkways effortless. The big win here is battery compatibility: all four batteries work across the entire Greenworks 40V ecosystem of 75+ tools, so you can add a chainsaw, hedge trimmer, or pole saw later without buying more batteries. Users consistently praise the lightweight nature of the mower, noting it’s easy enough for anyone in the household to operate.

The mower’s battery consumption is the main trade-off. Real-world users report that the 5Ah battery drains faster than expected, particularly in the self-propelled version of this platform (though this kit includes the push model). Some owners found they needed both the 5Ah and a 2Ah battery just to finish a modest front lawn. The mower also has a storage switch that can stick, causing starting issues—a known design quirk that Greenworks customer service has been inconsistent in resolving.

The WORX WG735 proves that a smaller deck doesn’t mean less capability. At just 27.7 pounds, this 14-inch mower is light enough to lift with one hand—a genuine advantage for anyone with narrow gates, raised garden beds, or multiple small lawn sections separated by patios. The cut-to-edge design allows the blade to reach within inches of fences and flower beds, reducing the need for follow-up string trimming. The 40V brushless motor runs two 20V batteries in series and delivers enough torque for small yards up to 1/8 acre on a single charge.

The 6-position height adjustment (0.8 to 3 inches) covers a good range, though some users noted the highest setting still can’t handle overgrown grass without scalping. The 2-in-1 bagging and mulching system works well, and the PowerShare battery platform means these same packs power WORX trimmers, blowers, and even 80V tools if you combine them. Owners particularly appreciate how quiet the mower is—one reviewer mentioned mowing without hearing protection for the first time.

The 14-inch cutting width is genuinely limiting for anything larger than a quarter-acre; you’ll make many more passes than you would with a 21-inch deck. Some users also noted that the side handle knobs protrude wider than the mower base, which ironically prevents you from trimming as close to walls as the cut-to-edge design promises. The assembly instructions are diagram-only, which a few users found frustrating. For small yards and precision trimming, however, this is an excellent tool.

The Scotts 62016S is the most accessible entry point to cordless mowing, offering a 16-inch cutting width powered by a 20-volt 5.0Ah battery. Its lightweight plastic deck (27.9 pounds) makes it extremely easy to push, store, and lift into a car trunk. The 2-in-1 mulching and rear-bagging system works well for small, well-maintained lawns, and the 12-gallon collection bag handles clippings without frequent emptying. The 3-position height adjustment (1 to 2.5 inches) is limited, but adequate for a small townhouse yard or a vacation property where you just need to keep grass in check.

Users with arthritis or limited strength consistently praise this mower for its effortless operation. The 20V battery charges in about 3 hours, and the mower cuts cleanly through typical lawn grass. At this price point, you’re getting a tool that covers the basics without frills—no brushless motor, no single-lever height adjustment, no LED headlights. For someone who just needs to mow a 50×100-foot lot without the noise and hassle of a gas mower, it fits the bill perfectly.

The battery life is the Achilles’ heel here. Multiple users report that the 5.0Ah battery lasts only 15–20 minutes under load, which may not even finish a small front yard. Some received defective batteries that wouldn’t hold a charge at all, and Scotts’ warranty support was criticized for not replacing defective packs. The 20-volt system lacks the torque to handle thick or tall grass; users with St. Augustine or Zoysia will likely find it underpowered. If you have a tiny, well-kept lawn, it works—but for anything more demanding, the extra investment in a 40V mower is worth it.
