8 Best Cordless String Trimmers for Large Yards (August 2026)

The best cordless string trimmer for a large yard is the EGO POWER+ ST1623T because its included 56V 4.0Ah battery is specified for up to 60 minutes of runtime, while its 16-inch swath, brushless motor, LINE IQ feed, and POWERLOAD head target the jobs that make a big property tiring. A large yard here means roughly half an acre or more, where trimming commonly takes 45 minutes or longer and a small battery can turn a simple chore into a stop-and-start job.

I would not pick a cordless weed whacker for acreage by voltage alone. Battery capacity, the thickness of the grass, how much fence line you have, the cutting width, and whether you work at high speed all affect how long a charge lasts.

Our research found the same concerns in lawn-care discussions: people want less noise and maintenance than gas, but they do not want a weak trimmer, a difficult spool, or a heavy machine that wears them out halfway around the property. This guide sticks to the documented specifications and customer ratings of eight battery powered string trimmers, with clear notes where a manufacturer does not publish a runtime figure.

A quick answer for shoppers: look for a brushless motor, a 15- to 17-inch cutting path, a battery system of 40V or higher, and at least a 4.0Ah battery for a long session. If you have dense weeds or a lot of acreage, a spare compatible battery is more practical than treating any single runtime claim as a promise for every condition.

The Top 3 Picks Answer the Biggest Large-Yard Needs

The EGO ST1623T is the complete long-session choice, the CAT DG610 is the lighter 60V kit with an ECO mode, and the DEWALT DCST972X1 suits owners who value a 17-inch maximum swath and universal attachment capability. Each makes sense for a different work pattern, so the cards below are a starting point rather than a claim that one trimmer fits every property.

These Eight Cordless String Trimmers Cover Large Yards in 2026

The comparison below includes every model reviewed. Treat claimed runtime and distance as manufacturer figures measured under their own conditions; taller grass, thick weeds, damp growth, and long high-speed use will reduce the time you get from a charge.

A 16-inch cutting width appears on six of the eight models, while DEWALT can run at either 15 or 17 inches and CAT uses a 15-inch path. That difference matters around open fence lines: a wider swath can reduce passes, but the faster head also asks more of the battery.

Ratings in this roundup range from 4.1 to 4.6 out of 5 based on the available review counts. The Greenworks Pro 80V has the highest listed rating at 4.6 from 88 reviews, but the EGO ST1623T has a much larger 2.2k-plus review base and a documented 60-minute kit runtime, which is why it is my overall recommendation for many large properties.

1. The EGO POWER+ ST1623T Is the Best Overall Long-Session Kit

The ST1623T is the most complete answer in this group for someone starting on a large yard because the 4.0Ah battery and charger come with it. EGO specifies up to 60 minutes on one charge, a figure that lines up well with the 45-plus-minute planning target for properties of half an acre or more.

I like that the core large-yard details work together rather than appearing as isolated features. The 16-inch swath covers ground efficiently, the 7.5-pound listed tool weight helps during long edging runs, and the carbon-fiber shaft telescopes so more than one person can set a comfortable working length.

LINE IQ is the feature that separates this model from a basic bump-feed cordless grass trimmer. It monitors and feeds line to maintain a continuous 16-inch path, while POWERLOAD lets you thread line through the head and press a button to wind it.

The manufacturer also lists a digital variable-speed selector, a high-efficiency brushless motor, and a 55-minute charge time for the included 4.0Ah battery with its supplied charger. Those are practical details for big-yard work: use the lower setting near light grass and save high output for thicker patches.

The ST1623T Fits Owners Who Want One Complete Battery Setup

This is the pick I would direct toward homeowners who do not already own a compatible battery platform and want a battery, charger, long stated runtime, and automatic line handling in one package. It also fits people with a lot of trimming around beds, trees, sidewalks, and fence posts, where repeated stopping to correct line length gets old fast.

The EGO 56V ARC Lithium platform accepts other EGO batteries, so a second battery can expand your work window later. That platform flexibility is a real decision point: buying into a battery family makes more sense when you expect to add other outdoor tools.

The ST1623T Requires Realistic Runtime Planning in Heavy Growth

Up to 60 minutes is not the same as a guaranteed hour in every kind of vegetation. Dense, wet, or woody weeds and long periods at the higher speed will ask more from the battery, so I would still charge the pack fully before a large cleanup and consider a second pack for acre-plus work.

The 4.4 rating comes from more than 2.2k reviews, which gives this model a broader feedback base than most of the list. Its limitations are not hidden: it is a higher-tier kit, and no battery trimmer removes the need to match speed and line use to the conditions.

2. The EGO POWER+ ST1610T Is the Best Lightweight POWERLOAD Option

The EGO ST1610T earns its place for people who already own EGO 56V ARC Lithium batteries or want to choose their own capacity. At 7.5 pounds, it has the same listed tool weight as the ST1623T and a 16-inch cutting swath, but it is sold without a battery and charger.

EGO specifies up to 45 minutes on a recommended 2.5Ah battery, available separately. That stated figure reaches the lower edge of my large-yard target, but the tool-only format means the final result depends on the battery you pair with it.

POWERLOAD is the feature I would prioritize if manual spool winding is one of your least favorite yard jobs. Feed the line through the head, press the button, and the trimmer winds it, rather than asking you to dismantle a spool after every refill.

The brushless motor is designed for longer runtime, low vibration, and long motor life, and the tool uses professional-grade dual-line 0.095-inch spiral-twist line. It also has IPX4-rated weather-resistant construction, which is useful for normal outdoor exposure but should not be read as permission to work in heavy rain.

The ST1610T Works Best for Existing EGO Battery Owners

If you already use EGO 56V equipment, this model may be the cleanest way to add a cordless edger trimmer without another battery family on the shelf. The compatibility with all EGO 56V ARC Lithium batteries gives you flexibility to select capacity based on your yard and whether a spare pack is already part of your routine.

The telescopic carbon-fiber shaft and quick-adjust auxiliary handle also make it a strong fit for households where different users share tools. I place a lot of weight on fit for long jobs because an awkward shaft length makes even a light trimmer feel much heavier by the last section of fence.

The ST1610T Needs a Battery Budgeted Into the Decision

Do not overlook the tool-only status. The 45-minute claim is tied to a recommended 2.5Ah battery, and the available listing does not bundle that battery or a charger, so a first-time EGO buyer needs to account for both before this becomes a ready-to-trim setup.

This model has a 4.5 rating from 75 reviews, the highest listed average here. It lacks the ST1623T kit’s included 4.0Ah battery and LINE IQ feature, but its lighter documented configuration and POWERLOAD head make it a thoughtful choice for owners who have already chosen the EGO platform.

3. The DEWALT DCST972X1 Is the Best Choice for a 17-Inch Swath and Attachments

The DEWALT DCST972X1 is the straightforward pick for large-yard owners who want a cordless string trimmer that can do more than trim. Its universal attachment capability can accept additional tool pieces, which can reduce the number of separate shafts stored in the garage.

Its adjustable cutting path runs at 15 or 17 inches with 0.080-inch dual line, and it can also use DEWALT 0.095-inch line. A 17-inch swath is the widest documented option in this list, so it has a real advantage when you have long, open borders to clear.

The high-performance brushless motor pairs with a variable trigger and high/low speed control. I would use the lower output near maintained turf and reserve the wider setting and higher speed for tall grass, because maximum coverage is not automatically the most battery-conscious way to work.

DEWALT lists the tool at 15 pounds and does not provide a runtime claim in the available product information. That means its performance case rests on adjustability, motor design, swath width, and attachment options rather than an advertised number of minutes.

The DEWALT Fits Yard Owners Building Around Attachments

This is the right direction if the attachment-capable shaft is a primary reason for buying. Owners with long property edges, brushy zones, or multiple seasonal chores may prefer one powerhead that accepts extra working ends instead of several independent machines.

The quick-load spool is another welcome detail for a large area because line maintenance is unavoidable. A design that makes re-spooling more convenient will not make line last forever, but it can make the interruption less frustrating when you finally run out halfway through a session.

The DEWALT Demands Attention to Weight and Battery Expectations

At a listed 15 pounds, the DEWALT is substantially heavier than the 7.5-pound EGO tools in this article. That may be an acceptable trade for its broader swath and attachment focus, but I would not dismiss the difference if you routinely trim for an hour or have wrist, shoulder, or back fatigue.

The 4.3 rating comes from more than 1k reviews, and the kit includes a battery and charger. Since a runtime is not stated in the source data, plan on charging fully, use the high/low control deliberately, and keep the battery system’s real work time in mind before committing to a very large property.

4. The Greenworks 60V Load N Go Is the Best Shoulder-Strap Kit

The Greenworks 60V model is built around an important large-yard reality: a tool can be powerful and still be unpleasant if all the weight sits in your hands. Its adjustable shoulder strap is meant to distribute that load during longer sessions, and the kit includes a 4.0Ah battery and charger.

Greenworks specifies a 16-inch cutting width and a brushless motor intended for strong cutting power, longer runtime, and consistent performance. The company does not state a number of runtime minutes here, so I would regard the supplied 4.0Ah pack as a useful capacity starting point rather than an acreage guarantee.

Load N Go aims to make line reloading quicker, and that matters more than it sounds when a large yard has many hard edges. User discussions repeatedly raise string replacement as a pain point, so a trimmer head designed to make that task less fiddly deserves attention.

This is also attachment capable and works with more than 75 Greenworks 60V products according to the listing. That broad platform is appealing for a homeowner who wants to standardize batteries across a mower, blower, hedge tool, or other garden equipment.

The Greenworks 60V Fits Long Sessions That Need a Shoulder Strap

I would shortlist this kit when the included strap matters more than the lowest possible weight. The listed 18.7-pound weight is significant, but a well-positioned strap can shift some strain away from the arms during a long pass around a large lawn.

It also makes sense for a new buyer who prefers a complete kit with a 4.0Ah battery instead of a tool-only purchase. The 16-inch path is a sensible middle ground: broad enough for steady progress without being as wide as the DEWALT’s maximum setting.

The Greenworks 60V Requires a Comfortable Fit Check

A shoulder strap helps only if you can adjust it to your body and use it without the shaft fighting your movement. Before a long job, I would set the auxiliary handle, attach the strap, and practice a few slow sweeping motions so the head stays level without excess wrist pressure.

The 4.3 rating is based on 131 reviews. The listing provides no runtime number, so buyers comparing this electric string trimmer with EGO’s stated 45- and 60-minute claims should recognize that capacity and voltage describe the system, while actual minutes still depend on grass, speed setting, and trimming technique.

5. The Greenworks 82V Commercial Is the Best High-Power Choice for Dense Growth

The Greenworks 82V commercial model is the power-focused option for tall grass and demanding work, not the effortless lightweight option. Its direct-drive commercial-grade brushless motor is rated at up to 1.5kW, and the manufacturer says the trimmer has 40 percent more power than a 36cc gas string trimmer.

It has a 16-inch cutting swath, a variable-speed trigger with a two-speed switch, a magnesium construction, and a 1.1-inch-diameter shaft. Those details point toward a tool meant to withstand repeated heavy use rather than a simple light-duty cordless weed whacker.

Greenworks claims up to 2.5 miles of trimming on a charge with the included 82V 2.5Ah, 180 watt-hour battery. I would not convert that distance into an acreage claim because a property’s perimeter, obstacles, and weed density vary too much, but it is useful as a linear-work reference for fences and long driveways.

The Load N Go head can hold up to 34 feet of 0.095-inch line. A higher line capacity can mean fewer reloads in dense growth, though thick vegetation naturally consumes line more quickly than maintained grass.

The 82V Greenworks Fits Thick Weeds and Long Linear Borders

Choose this model when cutting authority is more important than a low carry weight. I see its best use around long rural boundaries, coarse weeds, neglected edges, and regular heavy-duty sessions where a commercial-grade direct-drive motor and .095-inch line are meaningful advantages.

The two-speed design allows a more measured approach around light turf and a stronger setting when the work becomes difficult. That flexibility can extend a work session if you resist running full output in areas that do not need it.

The 82V Greenworks Is Not a Casual Platform Purchase

The listed 22-pound weight is the heaviest in this roundup. Anyone who finds a 15-pound trimmer tiring should take that figure seriously, even with the appeal of the higher-power motor and long line capacity.

Battery compatibility is equally important: this 82V tool is explicitly incompatible with Greenworks 80V products. The 4.3 rating is based on 17 reviews, a much smaller review pool than the leading EGO and DEWALT models, so its strong specification sheet should be weighed alongside the limited available customer feedback.

6. The Greenworks Pro 80V Is the Best 80V Attachment-Capable Starter Kit

The Greenworks Pro 80V is a compelling option if you want an 80V system, a 16-inch cutting width, and attachment capability with a more moderate listed 16-pound weight than the 82V commercial model. Its 6,300 RPM specification and brushless platform place it squarely in the serious homeowner category.

The listed kit includes a battery and rapid charger, and the product title identifies the included pack as 2.5Ah. The technical details separately state up to 30 minutes of runtime with a 2Ah battery, so I would flag that difference rather than assume a specific runtime for the 2.5Ah pack.

For a large yard, 30 minutes on the documented 2Ah reference is a reminder that voltage is not the whole story. A spare compatible battery, a measured trigger hand, and starting with the longest borders can make a shorter-runtime platform much easier to manage.

The adjustable auxiliary handle and push-button start support everyday comfort and simple operation. It also carries a four-year warranty for both tool and battery, giving the kit a meaningful ownership point beyond its cutting specifications.

The Greenworks Pro 80V Fits Owners Who Need Attachments and Warranty Coverage

This model is a good match for a homeowner who prefers an attachment-capable shaft and likes the reassurance of matching four-year coverage for the trimmer and battery. The 16-inch path is appropriate for open edges, while the adjustable handle can help tailor the tool to different heights.

Its 4.6 rating is the highest listed average in this group, though it comes from 88 reviews. I would view that feedback positively without treating it as a substitute for the much larger review samples held by some competing models.

The Greenworks Pro 80V Needs a Second-Battery Plan for Acreage

A manufacturer figure of up to 30 minutes with a 2Ah battery is below the 45-minute continuous-work target used in this guide. The package title names a 2.5Ah pack, but it does not publish a corresponding runtime, so do not create an exact minutes estimate from the two data points.

Assembly is required, which is a small but real first-day task. If your property regularly needs an hour or more of edge work, I would choose a larger compatible battery where available or treat this as a two-battery workflow rather than expecting one charge to cover every condition.

7. The Greenworks 80V ST80L2510 Is the Best Flexible 0.095-Inch Line Option

The Greenworks ST80L2510 is another 80V candidate, but its case is slightly different from the Pro 80V above. It pairs a 16-inch cutting path with .095-inch dual line, a variable-speed trigger, and a brushless motor described as delivering gas-comparable torque.

The package includes a 2.5Ah battery and charger, and the attachment-capable shaft accepts Greenworks and most universal attachments. That compatibility broadens its value as a property-maintenance tool, especially for owners who would rather swap working ends than store several full-size power tools.

I appreciate the straightforward .095-inch dual-line specification for tougher grass and weeds. Thicker line can be useful for hard work, but it also increases the importance of buying the correct refill line and avoiding unnecessary high-speed use in fine grass.

Greenworks does not publish a weight or runtime number for this listing. Those missing numbers do not make the trimmer unsuitable, but they remove two pieces of information that matter greatly for a large yard, so a buyer should not fill in the gaps with assumptions.

The ST80L2510 Fits Owners Who Want Thick Line and Tool Flexibility

This model has an appealing feature mix for a yard with some maintained areas and some stubborn perimeter growth. A variable trigger lets you modulate the head, while the 16-inch swath and .095-inch dual line give it the physical setup for productive trimming through heavier grass.

Attachment compatibility is its other major attraction. I would check the exact attachment interface before ordering any add-on, because the statement that it accepts most universal attachments is helpful but is not a substitute for verifying a particular accessory model.

The ST80L2510 Is Best Bought With Missing Specs in Mind

The listed 4.2 rating is based on 40 reviews, and the source does not state the tool’s weight. That is a concern for anyone who knows that fatigue is their deciding issue, because the difference between a light tool and a heavy one becomes obvious over a large perimeter.

Runtime is also not stated for the 2.5Ah kit. If you are deciding between this and the EGO ST1623T specifically for a long uninterrupted session, the EGO has a clearer 60-minute manufacturer claim; this Greenworks makes more sense when 80V compatibility, thick line, and attachments are your primary priorities.

8. The CAT DG610 Is the Best Light 60V Kit With ECO Mode

The CAT DG610 deserves a close look from shoppers who want 60V power without carrying one of the heaviest tools in the group. Its listed weight is 9.93 pounds, and it combines a brushless motor, a 15-inch swath, a dual-line bump-feed head, and a battery with charger in the box.

CAT says its Brushless Motor 2.0 produces 40 percent more power and 10 percent longer runtime, but the available listing does not identify the comparison baseline or give a number of minutes. I would treat the claim as an indication of the product’s intended performance, not as a planning number for a large property.

ECO mode is the feature I find most relevant for a mixed yard. It gives you a lower-output option for light grass and delicate spots, helping conserve battery capacity before you reach the thick weed patches that actually call for full power.

The Quick Line Load system and simple bump-feed advancement address two different parts of line management: loading fresh line and feeding it while working. Bump feed still asks you to monitor line length, but the setup avoids an automatic system for buyers who prefer a familiar mechanical approach.

The CAT DG610 Fits Large Yards With Mostly Routine Grass Trimming

This is a sensible cordless grass trimmer when long sessions are made harder by tool weight rather than by constant heavy brush. The sub-10-pound listing gives it a substantial comfort advantage over the 15-pound DEWALT and the two heavier Greenworks kits, while its 60V system is aimed above entry-level work.

The 15-inch swath is narrower than most models in this roundup, yet that can be easier to control around landscaping and garden beds. For a yard that mixes broad lawn edges with tight planting areas, the extra precision may matter more than maximum coverage on every pass.

The CAT DG610 Needs a Runtime Test in Your Own Conditions

CAT includes the battery and charger, but its capacity and an exact runtime are not provided in the available data. That makes this a good fit for owners willing to learn their property’s real battery use and add a compatible spare if one charge proves short.

The 4.1 rating from 132 reviews is lower than the other leading options, so I would not call it the universal best choice. Its strengths are its manageable listed weight, ECO mode, 60V setup, and line-loading approach; its tradeoff is less published runtime evidence for a demanding acreage job.

The Right Large-Yard Trimmer Starts With Runtime, Not Just Voltage

For half an acre or more, begin with the time you actually spend trimming instead of the size of the lawn on a property listing. A yard with a large open lawn but only a short fence may take less trimmer time than a smaller lot packed with trees, beds, retaining walls, gates, and a long driveway.

As a practical baseline, the research brief identifies 40V to 60V, 4.0Ah or greater, a 15- to 17-inch cutting width, and 45-plus minutes of runtime as strong targets for large yards. The EGO ST1623T is the clearest match in this group because it explicitly pairs a 4.0Ah battery with an up-to-60-minute claim.

A 4.0Ah Battery Is a Better Starting Point for Longer Jobs

Amp hours describe battery capacity, while voltage is part of the system’s electrical potential. Neither number alone predicts an exact trimming time, but a larger capacity battery can generally store more energy within a given platform, which is why 4.0Ah is a more useful starting point than a small pack for a long perimeter.

Manufacturer runtime claims are best treated as upper-limit references. Thick weeds, continuous high trigger use, a wide swath, damp grass, and frequent line contact with hard surfaces can all reduce runtime, so add a spare battery if finishing in one outing matters.

A 15- to 17-Inch Swath Is the Practical Range for Acreage

A wider cutting width clears more ground per sweep, which is helpful along open fences and long driveways. The DEWALT can reach 17 inches, while most reviewed options use 16 inches and the CAT uses 15 inches for a bit more control in tighter spots.

Do not select the widest head automatically if most of your work is around landscaping. A trimmer that feels controlled and balanced can be more productive over an hour than a wider machine that forces you to slow down or fight its weight.

A Brushless Motor and Variable Speed Help Match Power to the Job

Brushless motors appear across the reviewed options and are commonly chosen for efficiency, lower vibration, and longevity. Variable-speed control appears on the EGO ST1623T, DEWALT, Greenworks 82V, Greenworks ST80L2510, and other models, letting you avoid full output in light grass.

My simple approach would be to trim easy grass first at the lowest effective setting and save the dense fence corners for the higher setting. This reduces wasted battery use and gives you a more accurate picture of whether your yard calls for one battery or two.

A Comfortable Tool Matters as Much as Peak Cutting Power

Forum discussions repeatedly point to fatigue as a reason people regret a trimmer after buying it. The documented range here is wide: the EGO models are listed at 7.5 pounds, CAT at 9.93 pounds, DEWALT at 15 pounds, Greenworks Pro 80V at 16 pounds, Greenworks 60V at 18.7 pounds, and Greenworks 82V at 22 pounds.

Those numbers should be part of your shortlist, not an afterthought. A shoulder strap, adjustable auxiliary handle, telescopic shaft, and balanced battery placement can change the experience, but a heavier machine still asks more of the user during an extended session.

A Simple Line System Prevents the Most Annoying Mid-Yard Stop

Line replacement is a major ownership detail rather than a minor feature. EGO POWERLOAD automatically winds line after you thread it through, Greenworks Load N Go focuses on quick reloading, DEWALT has a quick-load spool, and CAT combines Quick Line Load with a bump-feed head.

There is no single best system for every owner. If winding a spool is the chore you hate most, POWERLOAD is compelling; if you prefer direct manual control while trimming, CAT’s bump-feed approach may feel more familiar.

The Battery Platform Should Match the Tools You Plan to Own

Battery compatibility can be the deciding factor when two trimmers look close on paper. EGO works across its 56V ARC Lithium batteries, the Greenworks 60V trimmer is compatible with more than 75 products in that line, and the attachment-capable models can expand the use of one shaft.

Pay close attention to platform boundaries. The Greenworks 82V model is expressly incompatible with Greenworks 80V products, so similar brand names and battery shapes should never be treated as proof of interchangeability.

Quiet Operation and Cold Batteries Need Practical Expectations

Battery trimmers avoid the exhaust and fuel handling of gas machines, and their quieter operation can be easier on neighborhood relationships. Noise still exists at the cutting head, especially when line hits stems, pavement, or fence material, so normal hearing protection and considerate working hours remain sensible.

Cold weather can reduce lithium-ion battery performance, even though these listings do not provide cold-weather runtime data. Store batteries indoors in a dry place, begin with a fully charged pack, and avoid expecting a warm-weather runtime claim to hold exactly on a cold morning.

These Answers Cover Common Cordless Trimmer Questions

The EGO ST1623T Is the Best Overall Choice for Large Yards

For the best cordless string trimmers for large yards, the EGO POWER+ ST1623T is my leading pick because its included 4.0Ah battery, up-to-60-minute runtime claim, 16-inch swath, 7.5-pound listed weight, and automatic line features address the major big-property frustrations in one kit. Pick the DEWALT for its 17-inch maximum path and attachments, the Greenworks 82V for heavy growth, or the CAT when lower listed weight and ECO mode matter most.

Choose the battery platform you can live with, charge before you start, and buy a spare pack when an uninterrupted session is important. That simple preparation is what lets a cordless tool remain a useful alternative to gas as your trimming list gets longer in 2026.
