A 30-pound push mower that fits a townhouse patio budget and a small yard.

At just 30 pounds and a 17-inch deck, this is the mower you grab for a quick weekly pass around a small city lot or a townhouse patch. The brushless motor spins at 3400 RPM, and the two included 4.0Ah batteries give you up to 25 minutes of cutting per charge. That is enough for most quarter-acre front-and-back jobs, but as owners mention, “fully charged batteries only last 15-20 minutes” in taller or wetter grass — so plan your mowing around dry conditions if you can.

The 2-in-1 system switches between mulching (returning nutrients to the soil) and bagging with a 40-liter collection bag. A single lever adjusts cutting height across 6 positions, from 0.98 to 2.95 inches. The foldable handle makes upright storage simple. For the price, the trade-off is clear: the battery average life of 25 minutes is a 2.4x gap compared to the EGO 56V above, so this is a dedicated small-yard tool. Owners praise its lightweight, easy maneuverability around trees and flower beds, and the fact that it requires zero gas or maintenance.

Compared to the RB 9-inch mini, this gives you a wider cutting path for a modest price bump, but it lacks the RB’s hour-long runtime and ultra-portable 11.5-pound weight. It is the sensible entry-level pick for anyone with a small, flat lawn who wants cordless simplicity without overspending.

A 9-inch deck and 11.5 pounds turn mowing into a one-handed vacuum job.

This little mower redefines what “eco lawn mower” can mean for a tiny yard. Weighing only 11.5 pounds without the battery, with a 9-inch cutting width and a pivoting front wheel, it steers with one hand and fits under furniture, shrubs, and low decks. The brushless motor spins at 6000 RPM, fine-mulching grass into clippings that stay under the housing — no bag needed. A buyer sums it up: “whole yard on one charge.” The 40V 2Ah battery delivers about an hour of runtime, which is a 2.4x longer cut than the STEELITE above.

The 9-inch deck is a 2.3x gap narrower than the EGO 21-inch, so it takes more passes on open lawn — but that is entirely the point. This is not your main mower for a quarter-acre; it is the perfect solution for a 540-square-foot patch, a patio, or a steep bank where larger machines slide or stall. Three cutting heights (1.2 to 2 inches) give you control. Safety features include an automatic shut-off if the mower tilts beyond 20 to 70 degrees, which resets with a trigger pull. Owners appreciate the near-silent operation and the detachable aluminum handle that stores vertically, saving up to 70 percent of storage space.

The main operational quirk: you must hold a blue button and the trigger to keep it running, and bumpy ground can trip the tilt sensor. But for anyone with a genuinely small space, this machine is a revelation. It beats the RB 40V hands down on portability, though that model lacks its larger cousin’s wider deck and higher voltage. If your “yard” is more of a postage stamp, this is your mower.

IntelliCut technology that dials up power automatically in thick grass.

For the quarter-acre homeowner, the Worx WG745 balances price, features, and real-world cut quality. It runs on two 20V 4.0Ah batteries (stacked for 40V) and uses IntelliCut technology — patented sensors that automatically raise the cutting speed when the grass gets dense, then dial it back to conserve runtime on thinner patches. The brushless motor delivers what Worx calls 40 percent higher cutting power over first-gen brushless motors, with a 17-inch deck that cuts close to fences thanks to the slim-profile design.

The mower weighs 39.7 pounds fully assembled, which is light enough to maneuver without self-propel. It offers 6 cutting heights (1.5 to 4 inches) via a single lever, and switches between mulching and rear bagging. The 2-in-1 system lets you return nutrients to the soil or collect clippings for a tidy finish. Performance is the top praise from owners — it handles tough weeds without hesitation and is notably quiet. The battery life covers a quarter-acre on one charge, though owners note that the charge indicator is helpful for planning. Assembly instructions draw the most criticism, with some reporting it took two hours to figure out. But once put together, the mower draws consistent praise for being “so quiet, and affordable, too.”

For the price, this is a solid step up from the STEELITE 40V. The Worx gives you a longer runtime, a better build feel, and IntelliCut that the STEELITE lacks. It is the pick for the budget-conscious buyer who wants modern battery tech without jumping to premium pricing.

Aerodeck venting and a 21-inch cut make this the half-acre workhorse.

If you have a half-acre and want a single mower that mulches, bags, and side-discharges, the WG752 is Worx’s answer. Its Aerodeck technology — a vented cutting deck — boosts air volume to prevent clogs and clumping, which means less stopping to clear the blade. The deck is 20 inches wide (labeled as a 21-inch mower), and with the included two 5.0Ah PowerShare Pro batteries, you get up to 50 minutes of runtime. That covers half an acre in a single session for most owners.

The brushless motor 2.0 delivers 40 percent more power than Worx’s first-gen brushless motors. IntelliCut technology is onboard again, automatically ramping up cutting speed in thick grass and conserving power in thin areas. The 7-position height adjustment (1.5 to 4 inches) gives you fine control. The 3-in-1 system adds side discharge to the mulching and bagging options, which is useful if you prefer to blow clippings onto a garden bed. Owners highlight the near-full assembly from the start — about 95 percent pre-assembled — and the upright storage. The main practical critique is that the batteries can be a bit stiff to remove, and the mulch quality is good but not flawless in damp conditions. Still, with 317 ratings averaging 4.4 stars, the consensus is clear: this mower handles a half-acre with minimal fuss.

Compared to the smaller WG745, the WG752 gives you a wider deck, bigger batteries, and side-discharge capability. Against the EGO 56V, it falls short on torque (7.0 ft-lbs versus the EGO’s gas-matching power) but matches it on features at a lower entry price. It is the sensible premium pick for owners who want to buy once and mow for years without touching gas.

Self-propelled rear-wheel drive at a price that undercuts the premium brands.

Greenworks takes a clever approach here: two 24V batteries combine to deliver 48V of power, keeping you on a 24V battery platform that is compatible with their other tools. The result is a self-propelled, 21-inch mower with a rear-wheel drive system and variable speed control for hills and thick grass. Runtime hits up to 45 minutes with two fully charged 5.0Ah USB batteries, which includes a dedicated Turbo button for maximum power in heavy patches or leaf pickup.

The brushless motor is efficient and quiet. The 4-in-1 system covers mulching, rear bagging, side discharge, and the Turbo boost for leaf pickup. Owners praise the ease of assembly (minimal steps) and the fact that it folds for upright storage. Battery life is the main trade-off: while Greenworks claims up to 45 minutes, real-world reports vary heavily with temperature and grass conditions. In 90-degree heat, one owner measured 15 to 20 minutes; in cool weather, 45 minutes was achievable. The batteries also take over two hours to recharge and require a one-hour cool-down first. For a quarter-acre lawn, this mower works, but a second battery pack is almost necessary for comfortable coverage. At 77 pounds, it is the heaviest mower on this list, but the self-propel takes the strain off the push.

Compared to the SKIL 40V below, the Greenworks 48V gives you a slightly wider deck (21 vs. 20 inches) and the Turbo boost feature, but it is heavier and its battery life is less consistent in heat. It is the right pick if you value self-propel on a mid-range budget and already own other Greenworks 24V tools.

A 20-inch deck with variable-speed self-propel and a 55-minute runtime at a mid-premium price.

SKIL enters the premium cordless market with a mower that punches above its price bracket. The PWR CORE 40 packs a 40V 6.0Ah battery and a digital brushless motor that delivers up to 55 minutes of runtime. That is enough to handle a third-acre or more on a single charge. The variable-speed self-propel lets you adjust the walking pace from a slow crawl to a brisk stride, which makes a real difference on slopes or through long grass.

The 20-inch deck offers 7 cutting height positions (1.5 to 4 inches) via a single lever. It is a 3-in-1 machine — bag, mulch, or rear-discharge. The foldable telescoping handle makes vertical storage easy, and the push-button start means no pull cord. The build quality is weather-resistant, adding durability if you store it in a shed rather than a climate-controlled garage. Owners consistently praise the battery life: it handles 1/3 acre on one charge, and the self-propel feature is described as a “standout” for larger lots. Some note that it struggles with wet, tall grass — any cordless mower does — but on dry lawn, the cut quality matches a gas mower. The main reported issue is a battery recall that was resolved by December 2024. Overall, with 4.5 stars across 181 ratings, this is a confident, well-rounded pick.

Compared to the Greenworks 48V, the SKIL is lighter and its battery life is more consistent across temperatures. It lacks the Turbo boost of the Greenworks, but the variable self-propel gives you more control on hills. It is the best option for homeowners who want premium features without jumping to the EGO ecosystem.

80 volts of torque and a 2-hour runtime — enough to cover half an acre without breaking stride.

Voltage matters for torque, and 80V is the highest in this lineup. The Greenworks 80V mower pairs that voltage with a brushless motor and a durable 21-inch steel deck to handle hills, thick grass, and even damp patches without hesitation. The included 4.0Ah battery delivers up to 2 hours of runtime, which covers a half-acre lot with power to spare. For comparison, that is a 2.4x longer runtime than the 50-minute EGO 56V above, and a massive 4.8x longer than the 25-minute STEELITE 40V

The rear-wheel drive self-propel system has variable speed control for maximum traction. A bright LED headlight lets you mow early morning or late evening — and it is rated 3x quieter than gas. The 4-in-1 system includes mulching, bagging, side discharge, and a Turbo button for leaf pickup or thick patches. Cutting height adjusts across 7 positions. Owners praise the power and the near-silent operation — neighbors genuinely cannot hear it running. Some find the self-propel locks the wheels when turning, requiring you to disengage the self-propel early. The mulch quality is adequate but not exceptional; the Turbo mode helps for thick spots. At 75 pounds, it is heavy, but the self-propel makes it feel much lighter on flat ground.

This mower beats the Greenworks 48V handily on voltage, runtime, and deck durability. It also outlasts the SKIL by a wide margin on runtime. The trade-off is the initial investment, which is higher than the 48V model. For owners with a half-acre or larger, or any yard with significant slopes, the 80V torque and 2-hour runtime make this the outright power champion.

EGO’s 6.0 ft-lbs of torque in a 50.9-pound package that starts with a button push.

If you want EGO quality but do not need the extra battery bundle of Product 1, this single-battery version is the way to go. It shares the same 21-inch deck and 56V platform, with a brushless motor that delivers up to 6.0 ft-lbs of cutting torque — enough to exceed the cutting power of many gas mowers. The included 6.0Ah ARC Lithium battery provides up to 50 minutes of runtime, which handles a half-acre in most conditions. The Dual-Toggle handleset lets you engage the self-propel with either hand, a thoughtful ergonomic touch.

Cutting height adjusts across 7 positions, from 1.25 to 4 inches. The 3-in-1 function covers mulching, bagging, and side discharge. Bright LED headlights make early morning or evening mowing practical. The adjustable handle height accommodates different users. At 50.9 pounds, it is 26 pounds lighter than the Greenworks 80V, making it much easier to lift into a shed or transport. The self-propel is fast on open grass, and customers note it can mow half an acre using about three-quarters of the self-propel speed without draining the battery completely. The main caution: the single battery is adequate for smaller half-acre yards, but for a full half-acre in tall grass, you will want the extra battery from the bundle version. Some reviewers point out clogging in very tall, wet grass, which is common across all electric mowers. The quality and battery life are the top praise points, and the overall rating of 4.5 stars from 310 ratings reflects broad satisfaction.

This is the pick for the buyer who wants the gas-replacing performance of the EGO ecosystem but already has other EGO tools and just needs the mower. It is lighter than the Greenworks 80V and SKIL, quieter than gas, and backed by one of the strongest reputations in cordless outdoor power.
