I'm done with gas and oil. What is the best battery-powered lawn mower for a 1/2 acre lot?

Mowing a true 1/2 acre (2 1,7 8 0 sq. ft.) lot—minus the footprint of your house and driveway—means you are looking at roughly 1 0,0 0 0 to 1 5,0 0 0 square feet of actual turf. While a 1/2 acre is technically doable with a high-end walk-behind battery mower, it pushes the absolute limit of standard walk-behinds in terms of runtime and stamina.

The best options on the market depend on whether you want to walk or ride:

The Gold Standard Walk-Behind: EGO Power+ 21" Self-Propelled Mower Go to product viewer dialog for this item. ( paired with a high-capacity 7.5 A hEGO Power+ or higher battery). EGO's 5 6 V ARC Lithium platform delivers true gas-equivalent torque. For a 1/2 acre, you will want a model that bundles at least a 1 0.0 A h battery or plan on swapping a secondary battery mid-mow unless your terrain is sparse and flat.

The Premium Comfort Walk-Behind: Toro 60V Max 22" Recycler with Personal Pace Go to product viewer dialog for this item. (e.g., Model 21469 with an 8.0 A h battery). Toro pairs legendary deck design and superior mulching with their Personal Pace auto-drive system that matches your exact walking speed. It has the raw power to cover a 1/2 acre, though heavy, thick spring grass may still require a quick battery top-off.

The "I Don't Want to Walk Anymore" Upgrade: EGO Power+ 42" T6 Lawn Tractor (TR4204)Go to product viewer dialog for this item. . If your 1/2 acre is flat-to-sloped and you are completely done spending 90+ minutes pushing a heavy walk-behind in the summer heat, a small battery-powered rider changes the game. It uses the same 5 6 V ecosystem, cuts up to 1.5 1.5 1.5 acres on a single charge, and completely eliminates the fatigue factor.

The Budget-Friendly Heavy Hitter: RYOBI 40V HP Brushless 21" Self-Propelled Mower Go to product viewer dialog for this item. . Coming with an 8.0 A h battery option, Ryobi’s 40V HP line punches well above its weight class, handles thick grass via smart electronic load-sensing, and offers great value for suburban and semi-rural lots up to a half-acre.

To help narrow this down, let me know:

• Is your 1/2 acre mostly flat or does it have steep hills/slopes?
• Would you prefer to keep walking (and save money/space) or switch to a riding mower?

For a 1/2-acre lot, I’d go with the EGO POWER+ LM2156SP Select Cut XP. It’s the strongest overall choice if your goal is to replace a gas mower without feeling like you compromised.

• EGO Power+ LM2156SP 21 in. 56V Self-Propelled Mower - $879.00 (Ace Hardware)

Why I’d pick the EGO

• Enough runtime for 1/2 acre: EGO rates the 10.0Ah battery for up to 75 minutes, and independent testing/reviews consistently put it among the best options for roughly 1/4–1/2 acre lawns.
• Excellent cutting power: Its 56V system produces 8.3 ft-lb of cutting torque, with a brushless motor that handles thick grass better than many cheaper battery mowers. EGO's own comparison chart confirms the 8.3-ft-lb figure and 75-minute runtime.
• Self-propelled: Important on a half-acre. You won't be pushing a ~90-lb mower around the whole property.
• Great mulching: Its Select Cut system gives you interchangeable blade configurations for different mowing jobs.
• 4-inch maximum cutting height: A useful advantage if you have taller grass varieties.
• No gas, oil, carburetor, spark plug, or winterizing. That's exactly where battery starts to feel dramatically better than gas.

My shortlist

• EGO LM2156SP Select Cut XP - $879.00 (Ace Hardware)
• Greenworks 80V Gen 2 Self-Propelled - $629.99 (Costco)
• RYOBI 40V HP 21-inch Self-Propelled - $688.97 (The Home Depot)
• Toro 60V 22-inch Recycler - $649.00 (The Home Depot)

The Greenworks 80V is probably the closest alternative. Current listings include a self-propelled 21-inch version, and Greenworks' 80V platform is specifically well suited to larger residential lawns.

One important caveat

If your actual grass area is close to the full 1/2 acre—not just a 1/2-acre property with a house, driveway, beds, etc.—I'd strongly favor the 10Ah EGO kit rather than a smaller-battery model. Runtime drops substantially with tall/wet grass, frequent self-propulsion, and aggressive mowing.

Bottom line: Buy the EGO LM2156SP. For a half-acre homeowner who is completely done with gas and oil, it's the one I'd spend the extra money on.

For a ½-acre lot, I’d buy the EGO Power+ 56V self-propelled mower, specifically the LM2156SP / 800 Series or the newer equivalent in EGO’s lineup.

• Greenworks 80V 21" Brushless Self-Propelled Mower - $449.99 (Best Buy)

My picks

• 🏆 Best overall: EGO Power+ 56V self-propelled — EGO’s 10Ah models are rated for up to 75 minutes, and independent 2026 testing puts the 1100 Series at roughly 0.49 acre of typical mowing on one charge. That makes the 10Ah version a particularly good fit for your ½ acre.
• 💰 Best value: Greenworks 80V 21" self-propelled — plenty of power, steel deck, and the 4Ah version is rated around ½ acre per charge. Current listings show it around $450–$700 depending on the battery configuration.
• 🌱 Best cut/value: Toro 60V Recycler 22" — excellent mulching and cutting performance. Independent testing found it particularly efficient per amp-hour, and the 8Ah version is rated for roughly ½ acre.

What I'd choose for you

EGO if you want the mower that's most likely to feel like a premium replacement for your gas mower. Get a 10Ah battery, rather than a smaller battery. EGO's own 2026 catalog rates the 10Ah 800-Series setup at up to 75 minutes, giving you a useful margin for thick/wet grass and less-than-ideal conditions.

Greenworks if you want to spend less. The 80V platform is especially compelling if you also want a battery blower, string trimmer, chainsaw, etc.

One important point: don't buy a small 40V mower just because the box says "up to ½ acre." For a true ½-acre property, I'd stick with 56V/60V/80V and at least ~7.5–8Ah of battery capacity if you want to comfortably finish without stopping.

If you tell me your budget (e.g. under $500, $700, or "money no object") and whether the yard is flat or hilly, I can narrow it down to the single mower I'd buy today and compare current prices.

Ditching gas and oil for a half-acre lot is a great move, but a 1/2 acre (roughly 21,780 sq. ft., minus your house and driveway footprint) is right at the upper limit for a standard 21-inch walk-behind mower. To pull this off without constantly swapping or recharging batteries mid-cut, you need high voltage, a large capacity battery (at least a 7.5Ah to 10.0Ah), and strong cutting torque.

The top contenders best suited to handle a 1/2-acre property cleanly and reliably include:

Add to list Widely regarded as the gold standard in cordless mowing . The XP series delivers up to 8.3 ft-lbs of cutting torque, easily matching a high-end gas engine . It features a multi-blade system (interchangeable mulching and bagging blades) and Touch Drive self-propelled technology . Paired with a large 10.0Ah or 12.0Ah battery kit, it gives you the stamina and power to cover up to 75–90 minutes of runtime , which is plenty for a 1/2-acre yard on a single charge. You can check out options and kit variations at Ace Hardware.

Add to list Greenworks offers fantastic gas-equivalent muscle with robust stamped-steel or heavy-duty decks . Their 60V dual-port auto-switch models or 80V systems punch way above their weight class and are explicitly rated to cover up to 1/2 acre when bundled with dual large-capacity batteries (like bundled 5.0Ah or 4.0Ah packs). They also fold vertically for compact garage storage . Look at current packages directly via Greenworks Tools.

Add to list If you love the feel of traditional gas Toro mowers, their 60V battery version with the famous Personal Pace self-propelled drive system (which automatically matches your walking speed) is fantastic. The 8.0Ah kit is rated to knock out a 1/2 acre cleanly on a charge and excels at mulching fine clippings back into the turf.

To help narrow down the exact model, tell me:

• Is your half-acre flat or hilly/sloped?
• Do you prefer to mulch your grass or use a bagger?

For a 1/2 acre lot (2 1,7 8 0 s q f t ), a walk-behind mower is totally doable, but it means you are looking at the upper limit of what a standard 21-to-22-inch walk-behind battery mower can comfortably handle on a single charge (usually requiring a high-capacity battery or a mid-session swap, unless you step up to a wide-deck or entry-level rider).

The top-performing, expert-backed battery lawn mowers suited for a 1/2 acre yard span a few targeted choices depending on whether you want a walk-behind or a small rider:

• Why it fits: Widely praised by expert testers at Wirecutter and Bob Vila , EGO's high-end 56V ARC Lithium systems (paired with a 10.0Ah battery) deliver gas-rivalling torque and enough runtime to get deep into a large yard . The multi-blade Select Cut system excels at mulching down thick or slightly overgrown grass without bogging down.

• The 1/2-acre caveat: You will want the kit with at least a 10.0Ah battery (or be ready to drop a second battery in) to finish a full 1/2 acre smoothly in one go.

• Why it fits: Toro's 60V Flex-Force lineup feels the most like a traditional gas mower , using an automatic-drive system that matches your walking pace and a legendary deck design that pulverizes clippings into fine mulch . It's sturdy, reliable, and handles heavy turf gracefully.

• The 1/2-acre caveat: Pairing it with an 8.0Ah or 10.0Ah battery gets you close to the edge of a 1/2 acre, though thick spring grass might require a quick recharge.

• Why it fits: Greenworks offers high-voltage options (like their 80V push/self-propelled models or dual-port AutoSwitch 60V platforms ) that pack serious power. If you go with a wider deck or a multi-battery kit, it chews through a large suburban lot without breaking the bank compared to premium ecosystem brands.

• Why it fits: Mowing a true 1/2 acre with a push or walk-behind electric mower takes about 45 to 75 minutes of solid walking and maneuvering. If you prefer riding, the EGO T6 lawn tractor uses multiple 56V ARC batteries combined to give you zero-emission, zero-oil riding power equivalent to a 21-horsepower gas engine across up to 1.5 acres.

To help narrow this down, tell me:

• Is your 1/2 acre flat or hilly?
• Would you rather walk behind a mower or upgrade to a small rider?
• Do you already own battery-powered outdoor tools from a specific brand (like Ryobi, EGO, or Greenworks)?

If you're replacing a gas mower for a true 1/2-acre lot, I'd buy the EGO Power+ LM2156SP Select Cut XP.

EGO POWER+ 56V 21-in Self-Propelled Mower

$649.00

Why EGO is my pick

• Enough battery for a 1/2 acre: EGO rates the LM2156SP's 10Ah configuration for up to 75 minutes, and current 2026 comparisons consistently put it among the strongest choices for 1/3–1/2-acre lawns.
• Excellent cutting power: Its Select Cut system lets you optimize the blade for mulching, bagging, or runtime—particularly useful if your grass gets thick.
• Self-propelled: Important on 1/2 acre, especially if you have any slope.
• 56V platform: The battery also powers EGO's trimmer, blower, edger, etc., so you can eventually eliminate gas from the whole yard.
• No oil, gas, carburetor, spark plugs, or winterizing.
• Good storage: It folds for vertical storage, which is surprisingly useful with a big mower.

One caveat: 75 minutes is a maximum, not a guarantee. Tall/wet grass, aggressive self-propel use, slopes, and a heavily loaded bag can cut runtime substantially. For a full 1/2 acre, I'd prioritize the 10Ah battery configuration rather than buying a smaller-battery EGO kit.

Two alternatives I'd seriously consider

Greenworks 60V 25-in Self-Propelled

$698.00

EGO 56V 22-in Select Cut

$1,099.00

Toro 60V 21-in Recycler

$529.00

Best value: Greenworks 60V 25". The 25-inch deck is a big deal on 1/2 acre—it reduces the number of passes—and the current kit includes two 4Ah batteries. Greenworks rates it for up to an acre, though real-world performance obviously varies with grass and terrain.

Best premium/fast option: EGO 22" Select Cut. If you don't mind spending more, the wider 22-inch deck and dual-battery setup make this attractive for a larger property.

Best traditional-mower feel: Toro 60V Super Recycler. Toro's cutting and mulching performance is excellent, but it's considerably heavier and I prefer EGO's battery ecosystem for someone making a complete transition away from gas.

My ranking for your situation

RYOBI 40V HP 20-in Push Mower

$458.00

Bottom line: For a 1/2-acre suburban lot, I'd spend the extra money on EGO rather than trying to save $150–$250 on a smaller battery mower. The bigger battery and stronger platform are exactly what make the gas-to-battery transition painless.

If you tell me your grass type (e.g. Bermuda, St. Augustine, fescue), whether the yard is flat, and your budget, I can narrow this down to the exact mower/battery configuration I'd buy.

A 1/2-acre lot (roughly 21,780 sq. ft., minus your house and driveway) is the sweet spot where cordless electric mowers transition from "casual weekend tools" to heavy lifters. A standard 21-inch walk-behind mower will take about 45 to 60 minutes of solid runtime, meaning you need high torque, a wide deck, and a robust battery capacity (at least a 1 0.0 A h battery or a dual-battery setup) so you aren't stuck mid-lawn waiting for a recharge.

Top-tier, gas-replacing options tailored for a 1/2-acre property include:

Widely regarded as the gold standard for large yards , EGO’s 56V platform matches the torque of high-end gas engines . The LM2156SP paired with a 1 0.0 A h battery gives you up to 75 minutes of runtime (plenty for 1/2 acre), while the multi-blade Select Cut system handles thick or slightly damp grass effortlessly.

If you are already running Milwaukee tools on the M18 battery platform, this commercial-grade steel-deck beast is an elite choice. It requires two 1 2.0 A h High Output batteries running simultaneously to deliver immense torque (surpassing a 2 0 0 c c gas engine) and will cleanly cut 1/2 acre on a single charge. It's pricey, but built like a tank.

If you want a battery mower that feels and acts identically to a traditional gas Toro, this is it. The legendary Recycler cutting deck provides exceptional mulching, and the smart-drive system matches your walking pace smoothly. A high-capacity 6.0 A h or larger battery bundle will get you through a 1/2-acre yard, though heavy overgrowth might require a quick top-off charge.

A fantastic value-forward option that delivers gas-comparable power (outperforming a 1 6 3 c c engine). It features dual-battery active ports so you can load two batteries at once, minimizing downtime, and comes in significantly cheaper than EGO or Milwaukee while handling flat-to-sloping 1/2-acre yards with ease.

To help narrow down the absolute best fit , tell me:

• Is your half-acre mostly flat or hilly/sloped?
• Do you prefer to mulch, bag, or side-discharge your clippings?
• Do you already own battery-powered tools from a brand like Ryobi, Milwaukee, or DeWalt?

For a ½-acre lot, I’d go battery without hesitation. You’re right at the size where battery mowers are now genuinely competitive with gas.

🏆 My pick: EGO POWER+ 56V

EGO POWER+ 600 Series 21-in Self-Propelled

$599.00

The EGO 56V platform is my first choice for a ½-acre property because it gives you plenty of power, a mature battery ecosystem, and excellent runtime. EGO’s 2026 lineup includes models rated around 60–90 minutes, depending on battery/model, with self-propelled versions available.

The 600 Series above is $599 with a 6.0Ah battery and charger right now. For a typical ½-acre lawn, that's a very sensible sweet spot.

Why I'd buy it:

• 21" deck — maneuverable without being slow
• Self-propelled
• 56V brushless motor
• Excellent cut quality
• Battery can power EGO's trimmers, blowers, chainsaws, etc.
• No oil, gas, carburetor, or winterizing
• EGO's current mower lineup carries 5-year tool warranties on many models.

Two excellent alternatives

Toro 60V 22-in Recycler

$649.00

Greenworks 60V 25-in Self-Propelled

$698.00

Greenworks 80V 21-in Gen 2 Self-Propelled

$629.99

Toro 60V 22" Recycler — best gas-mower replacement.
If you're accustomed to Toro's feel, this is probably the easiest transition. Independent testing found its runtime sufficient for nearly ½ acre, with very good mulching and a gas-mower-like control layout. www.protoolreviews.com It's currently around $649 with battery/charger.

Greenworks 60V 25" — best if you want to mow faster.
That enormous 25" deck can make a noticeable difference on ½ acre. The current version claims up to 1 acre of coverage and up to 80 minutes depending on configuration. The downside is that it's a fairly large, heavy machine.

What I'd choose for your property

One important point: don't buy based solely on the advertised acreage. Battery runtime depends heavily on grass height, moisture, terrain, cutting height, and how much self-propel you use.

If you tell me your budget (e.g. <$500, $500–700, or money-no-object), whether the lot is flat/hilly, and whether you already own any EGO/Greenworks/Toro/Ryobi batteries, I can narrow it down to the exact model I'd buy.

For a 1/2-acre lot, I’d go with a high-voltage, self-propelled mower with at least ~7.5–10 Ah of battery capacity. You’re right at the size where the cheaper 40V-class machines can become frustrating.

🏆 My pick: EGO POWER+ 800 Series Select Cut

EGO 800 Series Select Cut 21-in Self-Propelled

$749.00

Why I’d buy it for 1/2 acre:

• 56V platform with a 7.5 Ah battery
• Self-propelled, which matters on a half-acre
• 21-inch deck is a good compromise between maneuverability and mowing speed
• Excellent cut quality and plenty of power for normal residential grass
• EGO has a large battery ecosystem if you eventually want to ditch gas for your trimmer, blower, etc.
• Current listing is about $749, though prices fluctuate.

For a half-acre, I'd rather have this than a smaller/cheaper mower that forces you to worry about runtime every time you mow.

🥈 If you want to finish faster: Greenworks 60V 25"

Greenworks 60V 25-in Self-Propelled

$698.00

This is particularly interesting for your lot because the 25-inch deck covers substantially more ground per pass, and the package includes two 4.0 Ah batteries. Greenworks rates it for up to an acre, although real-world runtime varies considerably with grass height, moisture, and self-propel speed.

I'd choose this over the EGO if mowing time is your biggest concern.

🥉 Best "just like my old gas mower" choice: Toro 60V Recycler

Toro 60V Recycler 22-in Self-Propelled

$649.00

The 22-inch deck, rear-wheel drive and Personal Pace system make it a very natural transition from a gas mower. Toro's current lineup includes models designed for yards up to 2/3 acre, so your 1/2 acre is comfortably within its intended range.

What I'd choose

One important point: don't judge battery mowers by the advertised "up to X acres." That's typically under favorable conditions. For a half acre, I'd want enough battery capacity that you can finish comfortably even when the grass gets tall or wet.

If you tell me your budget ($500, $700, $1,000, etc.) and whether the yard is flat or hilly, I can narrow this down to the one I'd actually buy for your property.

A 1/2 acre lot is right at the upper threshold for a standard walk-behind battery mower. While totally doable on a single charge with the right high-capacity setup, it means you will want a self-propelled model with a wide deck and a robust battery (1 0.0 A h or larger), or you'll be swapping batteries mid-job.

The top-performing, expert-tested battery mowers capable of handling a 1/2 acre lot cleanly without the gas headache include:

Widely considered the gold standard for walk-behind electric mowers. The 5 6 V platform paired with an included heavy-duty battery (1 0.0 A h ) easily covers up to a half-acre. It features a multi-blade system that rivals high-end gas suction/mulching, TouchDrive self-propelled variable speed, and folds vertically for compact storage.

An incredible value-to-performance pick. Look for the kit bundling an 8.0 A h or dual 6.0 A h batteries. It kicks into a smart "Turbo" mode when it hits thick turf, gives you true gas-equivalent power (around a 1 6 3 c c gas match), and leaves you with a battery that fits into Ryobi's massive 4 0 V yard tool ecosystem.

If you love the precise cut and legendary mulching capability of a traditional Toro deck, their 6 0 V line bridges the gap effortlessly. It feels, handles, and controls identically to a classic gas Toro, making the transition painless while comfortably chewing through a 0.5-acre footprint on a large capacity 6.0 A h battery bundle.

If your 1/2 acre is heavily sloped, obstructed by complex landscaping, or you simply prefer riding over walking for 45+ minutes in the heat, this entry-level battery rider uses the same 5 6 V ARC Lithium batteries to cover up to 1.5 acres per charge. It's essentially a 2 1 H P gas tractor equivalent with zero emissions or belt/oil maintenance.

To help narrow down whether you should push walk or go for a rider, tell me:

• Is your 1/2 acre flat or hilly?
• Do you prefer to mulch, bag, or side-discharge your clippings?
