The best string trimmer for large yard work cuts a wide swath, carries enough battery or fuel for a long stretch, and does not wear you out at the far end of the row. I trim the tree rows, fence lines and hedgerow bases around a 3.7-acre orchard, and I put these nine through that work.
My top pick is the EGO Power+ MST1501 56V Multi-Head String Trimmer Kit, a 15 in. trimmer with a 5.0Ah battery in the box. Below you get the full ranking, what to check before you buy, and who should skip each one.
Best String Trimmer for Large Yard Reviews 2026 With 9 Picks for Long Jobs
These are the nine trimmers I put to work on a large property, ranked from the one I reach for first to the ones that suit a narrower job. Each block gives the swath, the run time the maker states and a plain note on who should skip it.
1. EGO Power+ MST1501 56V Multi-Head String Trimmer Kit Best Overall
The EGO MST1501 is my first pick when one battery has to carry real distance along tree rows and fence lines. Its 15 in. swath keeps the pass count down on a long edge, and according to EGO the 5.0Ah pack in the box runs up to 45 minutes per charge. I treat that figure as a planning number and split the day into blocks around it.
WHY I CHOSE THIS ✓
I chose the MST1501 because a large yard punishes a small battery first, and the 5.0Ah pack deals with that before the job starts. A 15 in. swath on a 5.0Ah pack covers a lot of ground between swaps. It is the trimmer I take on the long jobs.
EGO Power+ MST1501 56V Multi-Head String Trimmer Kit Specs
Key Features:
- 15 in. swath: each pass along a fence line or tree row clears a wide strip, so a long edge takes fewer trips.
- 5.0Ah battery in the kit: a long stretch of trimming needs fewer stops for a fresh pack.
- Two-speed switch and variable trigger: low for light grass, high for dense growth, with the trigger setting the speed inside each position.
- Rapid Reload bump head: tap it on bare ground to release line, and reload by hand with one 16 ft piece of line.
- Attachment-capable power head: EGO lists an extension pole, an edger and a pole saw for it, all sold separately.
- 0.095 in. twist line: the heavier line stands up to weeds along a fence, and the head also accepts 0.080 in.
- 5-year tool warranty: EGO covers the tool five years and the battery three, as limited warranties.
Along the tilled strips under my plum trees the 15 in. circle takes the grass right to the soil edge in one pass, and the low setting keeps the line gentle on the cover crop I want to leave standing. EGO’s manual says to cut grass over 8 in. from the top down in small steps, so a hay-high corner takes layers. The manual rules out blades and the head will not clear woody stems, and along a fence line the 0.095 in. line copes with thick weeds but wears fast where it rubs on wire.
EGO publishes 3.51 lb for the trimmer attachment alone, and the power head and the 5.0Ah pack ride on top of it, so I lift the whole set before I commit it to a long day. EGO’s manual lists a missing guard, a heavy line, a head bound with grass, motor overload and a trimmer or battery hotter than 152 F (67 C) as the reasons the motor stops, so I cut thick growth in shorter bites.
Drip lines lie close to the soil along my tree rows, and a spinning line cuts tubing as easily as grass, so I lift the line clear before I trim that edge. The manual warns that wire and picket fences wear line, and that stone walls, curbs and wood wear it quickly, so I keep a spare length of line in my pocket on fence days. The PH1400 power head behind the trimmer takes only the four EGO tools its manual lists: extension pole, edger, string trimmer and pole saw. Each extra tool is a separate purchase.
Tap the head on bare soil, never on the gravel yard, where a bump throws stones. EGO also warns that tapping in tall grass can overheat the motor.
Every time, use ANSI Z87.1 eye protection and hearing protection, long pants and non-slip footwear, with no loose clothing, and keep people and pets at least 100 ft away, the distance EGO’s manual gives for this attachment.
The pack leaves the tool whenever I clear a wrapped head: release the trigger, wait for the head to stop, take out the battery, then clear the head. The same 56V pack works in other EGO POWER+ tools, according to EGO, which makes a second pack a sensible purchase. Line loading is by hand, one 16 ft piece wound until about 5.5 in. shows on each side, and that reload is the one chore I notice. For routine wear parts such as the trimmer head, EGO’s page gives 90 days of cover for home use, so I check the head for cracks before each long job.
Buy it if you cut long tree rows, fence lines or open grass and want one battery to carry a real stretch of work. Skip it if you want an automatic-feed head or a published weight for the whole set. Nobody should run it in rain, and it is no tool for brush or saplings. EGO puts the bystander distance at 100 ft, so a small, crowded yard is the wrong place for it.
FINAL VERDICT
For the long edges and open grass of a large yard, this is the best string trimmer for large yard work that I can recommend first. It brings the swath and the pack in one kit. Buy it for long jobs that start from a single battery.
It is the long-row trimmer I plan my day around.
2. Makita XRU15PT1 36V LXT Brushless String Trimmer Kit Best Premium
The Makita XRU15PT1 solves the problem that stops a big job: a flat battery. The kit holds four 5.0Ah packs and a dual-port charger, so one pair works while the other pair charges. Makita claims up to 1.5 hours of run time on 18V LXT 5.0Ah packs, and the 15 in. swath keeps the passes down.
WHY I CHOSE THIS ✓
It earned its place because the kit includes a spare pair of packs for a long job. Makita’s 1.5-hour claim on 5.0Ah packs is the maker’s figure, and the second pair gives me room to keep cutting. The electric brake stops the head when I step back to pick up a stone.
Makita XRU15PT1 36V LXT Brushless String Trimmer Kit Specs
Key Features:
- Four-pack kit: two packs run the tool as 36V while the other two charge or wait, so the work stops only for a swap.
- Three fixed speeds: tap the power button to cycle 3,500, 5,300 and 6,500 rpm with no load.
- Automatic Torque Drive: hold the reverse button until the ADT light comes on and the tool adjusts speed and torque to the grass, per Makita’s flyer.
- Reverse button: a short reverse spin throws off wrapped weeds, and anything it leaves needs the tool off and the batteries out.
- Electric brake: the head stops fast when you release the trigger, and Makita says to have the tool serviced if it does not.
- Loop handle and steel drive shaft: a two-handed hold made for long runs, with a 69-1/4 in. overall length before the cutting tool.
- 18V LXT platform: the same packs run Makita’s 18V LXT tools.
Speed is where this trimmer earns its price along a long edge. I use the low setting along the house lawn, medium on the alley margins and high for tall growth against a fence, and I tap the power button to move between them. Makita says the head takes only 2.0 to 2.3 mm line, and the manual forbids heavier line, wire and rope. On mixed grass I hold the reverse button until the ADT light comes on, and the tool picks the speed and torque, which saves a lot of thumb work.
Up to 1.5 hours is Makita’s claim with 5.0Ah packs, and the flyer states no conditions, so I plan in pairs of packs and not in hours. A pair that comes off a hot yard waits a few minutes before it goes on the charger, because charging runs only from 10 to 40 C. The weight is the price of the kit: Makita lists 7.6 lb without batteries and 10.4 lb with them, and the manual asks for a 10 to 20 minute rest every hour. Makita also lists XPT dust and water resistance for the tool, which I read as protection from damp morning grass and nothing more.
At the hedgerow base the long grass wound around the head and the reverse button spun it free. When it did not, I switched off, waited for the head to stop, took both batteries out and only then touched the head, as the manual requires. Makita’s manual says the shoulder harness must be worn whenever one is supplied with the tool, so check the box for one. The same 18V packs also fit Makita’s LXT tools, and the overall length without the cutting tool is 69-1/4 in.
Swap both packs of a pair at the same time, because the tool needs both batteries fitted, and put the used pair on the charger only after it has cooled into the 50 to 104 F charging range. I make the swap at the end of a row.
Wear goggles and hearing protection, work overalls, and a dust mask in dusty growth, and keep people and animals 50 ft (15 m) away. The head keeps spinning after the motor stops, so wait for it to stop, take out both batteries, then touch the head.
Charge only between 10 and 40 C (50 to 104 F), and let a hot pack cool before it goes on the charger. Makita says to take packs off the tool and charger when they sit unused, so I keep the four packs in one dry place. What annoyed me was the weight of the tool after an hour, which the rest breaks answer. The manual says abnormal vibration means stop at once, so after a strike on a stone I switch off, wait for the head to stop and take out both batteries before I check the head.
Pick it if you cut long jobs and want a spare pair ready, or if you already own 18V LXT tools. Skip it if you want a light tool, an edger or any attachment system. The manual points to a separate warranty sheet, so read it before you buy.
FINAL VERDICT
This is the kit for a yard where the cutting runs long. Four packs mean a spare pair is ready when the first pair runs down. Buy it if the job is long and you can live with the weight.
It is the four-pack trimmer for long edges.
3. Greenworks Pro 60V ST60L254 16-Inch String Trimmer Best Value
The Greenworks ST60L254 is the value pick for a large yard that you cut in pack-sized blocks. For a mid-range price you get a brushless 60V motor, a 16 in. swath, a battery and a charger in one box, with a four-year warranty on the tool and the battery. It is a plain trimmer, and that is why it stays useful.
WHY I CHOSE THIS ✓
It made my top three because it gives a large yard the basics at a mid-range price. Best value here means a big swath, a brushless motor and a four-year warranty in a kit with the battery included. It is the weakest on this page at attachments and at battery count, so I keep it for the long grass edges and leave thick work to a tool made for it.
Greenworks Pro 60V ST60L254 16-Inch String Trimmer Specs
Key Features:
- 14 in. or 16 in. swath: it ships at 14 in., and turning the cut-off blade 180 degrees gives 16 in.; the manual says 14 in. for greater run time and 16 in. for a larger cutting area.
- Brushless 60V motor: the manual lists the motor as 60V brushless, with a no-load speed of 6000 rpm on high and 5000 rpm on low.
- Two-speed switch and variable trigger: position 1 is low, position 2 is high, and the trigger varies speed within each.
- Load N’ Go head: twist the spool cover to load line with no disassembly.
- Dual line, 0.080 in. or 0.095 in.: pick the line to the job, with no more than 15 ft loaded at a time.
- Battery and charger in the box: the kit holds a 2.5Ah pack and a 3A charger, and Greenworks lists a 50 minute recharge.
- Four-year warranty: the manual covers tool and battery for four years of personal use.
Out of the box it cuts a 14 in. circle. For the open edges I turned the swath to 16 in.: tool off, head stopped, battery out, gloves on, cut-off blade screws out, blade turned 180 degrees, screws tight again. Greenworks says 14 in. gives the longer run time, so on a tight job I set 14 in. before I start. This tool handles grass and light weeds, as the manual says, and the woody regrowth at the hedgerow waits for loppers.
Greenworks states up to 53 minutes on the 2.5Ah pack, with no conditions, and its page lists a 50 minute recharge. The 60V pack fits more than 75 Greenworks 60V tools, so a second pack is a sound purchase. A pack that runs down in the middle of a fence line tells me where the kit stops.
At the gravel yard I follow the manual’s cutting tip and pass the head from right to left, so thrown stones leave to the side away from me. The guard throws, glasses stay on and the tool stays below waist height. At 7.9 lb without the battery it feels like a light, honest tool after the first long strip. The manual allows no blade and Greenworks lists no attachment, which is a limit worth knowing before you carry it to the hedgerow, and the dual line takes 0.080 in. on tidy lawn edges and 0.095 in. along the fence.
When the motor runs faster than normal or the cut gets ragged, the line is short. Bump the head to advance it, and use the tip of the line to cut, tilting the head toward the area you are working.
Wear safety glasses with side shields marked ANSI Z87.1, since the manual says everyday glasses are not safety glasses, together with protective footwear and close-fitting clothing. Keep bystanders, children and pets at least 50 ft away, keep your body clear of the cutting area the manual shows, and never use the tool in rain or damp conditions.
Charge between 39 and 104 F and store the trimmer between 32 and 113 F. Before I clear wrapped grass, I release the trigger, wait for the head to stop, remove the battery and let the motor cool. Keep the vents clear so the motor does not overheat, and clean the tool with a moist cloth, never a hose or a spray. What annoyed me was the blade turn that changing the swath takes, so I choose the width before the job.
Choose it if you cut a medium to large yard in pack-sized blocks and want brushless power without a premium kit. Skip it if you need attachments, a blade for brush, or several packs for a very long job. Commercial users should skip it too, because the warranty covers personal use only, and the manual says the tool is not for rental or industrial use.
FINAL VERDICT
A sensible way into a wide-swath battery trimmer, this one does the grass work well and stops there. Pick it if you will cut in blocks and keep a second pack in mind.
It is the value trimmer for yards I cut in blocks.
4. EGO Power+ ST1623T 16-Inch Auto Feed String Trimmer Best Auto Feed
Tapping a trimmer head on gravel throws stones, so I was glad to find a head that never asks for it. The EGO ST1623T feeds its own line: when either end wears shorter than 7 in., the Line IQ head releases more and the guard blade trims it to length. Add a 16 in. swath and a 4.0Ah pack that EGO rates at up to 60 minutes, and you have a trimmer for long edges that stays out of your way.
WHY I CHOSE THIS ✓
I rank it fourth because a head that feeds itself removes the most irritating chore on a gravel yard. Line IQ and POWERLOAD together mean I never tap the head or wind line by hand.
EGO Power+ ST1623T 16-Inch Auto Feed String Trimmer Specs
Key Features:
- Line IQ automatic feed: the head releases line on its own when an end drops under 7 in., with no bump needed.
- POWERLOAD: a button winds a full spool in about 12 seconds, and EGO’s manual says not to repeat it in rapid succession.
- 16 in. swath: a wide circle for long open edges.
- Two-speed switch with an indicator: one light is low, two lights are high, and the manual says low gives control and longer run time.
- Height-adjustable carbon fiber shaft: a hinged shaft with a clamp that slides it to your length.
The first thing I noticed was the quiet rhythm of the head: a slight tremor now and then, which the manual says is the line being released. I never stopped to tap it, even along the gravel yard edge where a bump would have thrown stones. I cover this head and the 4.0Ah kit in my EGO ST1623T review.
EGO claims up to 60 minutes of continuous cut time with the 4.0Ah battery, with no conditions stated, and the manual says the low speed lasts longer. The manual lists 7.67 lb for the tool and does not say whether the battery is counted. The shaft is the part I set first: the clamp slides it to my height, and I check that the front handle sits where the manual allows.
Do not press the POWERLOAD button in quick succession. EGO warns that the motor can be damaged.
Never fit metal-reinforced line, wire or rope, because pieces can break off and fly at you or at anyone nearby. The manual says to use ANSI Z87.1 eye protection and hearing protection every time, and I add long pants, sturdy boots and gloves.
If the line gets pulled into the head, EGO says to open the lower cover and reload by hand. Replacing the head takes an impact wrench and gloves, which is the one maintenance step I plan for before the season. Before I touch the head for anything, I release the trigger, wait for the head to stop, take out the battery and then clear it. I keep the line off young trunks, since the manual warns that bark is easily damaged.
Get it when you trim along gravel, walls or any hard edge where tapping a head is a nuisance, and you want a wide swath. Skip it if you want a trimmer that takes heavier line, a blade or an attachment. The head has more moving parts than a plain bump head, which matters if you repair your own tools. I also put it head to head with a Makita kit in EGO ST1623T against Makita XRU15PT1.
FINAL VERDICT
Large yards with hard edges are where this trimmer belongs. The head looks after its own line, and that matters more on gravel than any spec. Pick it when tapping the head is the part of trimming you like least.
It is the trimmer that feeds its own line.
5. Husqvarna 130L 28cc Gas String Trimmer Best Husqvarna
I mix fuel for the Husqvarna 130L as its manual gives it: 2 1/2 fl oz of two-stroke oil for air-cooled engines to a US gallon of gasoline for the 50:1 ratio, in a can, outdoors, and no more than a month’s worth at a time. If you want the best Husqvarna weed eater for open ground with no pack to swap, the 130L is the one. It has a 28 cc engine, an 18 in. swath and a straight shaft.
WHY I CHOSE THIS ✓
I included it because gas gives a large yard a trimmer with no pack to swap. Fill the tank, pull the rope and cut a run at a time, with rests.
Husqvarna 130L 28cc Gas String Trimmer Specs
Key Features:
- 28 cc two-stroke engine: a catalytic converter muffler and 0.7 kW output at 8,000 rpm, per the manual.
- 18 in. swath: a wide circle for open grass.
- RapidReplace head: reload by pushing a 22 ft piece of line through the holes and turning the head.
- Straight shaft with a loop handle: reaches under fence lines and hedgerow bases.
- Purge bulb and choke start: 10 pushes of the bulb on a cold start, then the choke and the rope, as the manual lays out.
Along the fence line the 130L cuts at full throttle, and I drop to about 80 percent near posts, as the manual advises for work near objects. The line stays parallel to the ground, and The head is bump feed, so I tap it on firm ground at full speed. In tall grass the tap does not work, so I stop the engine, wait for the head to stop, let it cool, take off the spark plug lead and then pull line out by hand. My review of the Husqvarna 130L covers the fuel mix, start routine and upkeep in more detail.
The tank holds 0.5 L, so I watch the work and refuel at row ends. The manual lists 11.0 lb without fuel, cutting attachment and guard. Neither it nor Husqvarna’s 12.2 lb page figure includes fuel.
Soak the line in water for two days before loading it, since the manual says it lasts longer.
The manual lists ANSI Z87.1 goggles, hearing protection, gloves, heavy long pants, long sleeves and heavy slip-resistant steel-toe boots, and never start or run it indoors, in a shed or in a garage, even with the door open, because of carbon monoxide. Refuel outdoors with the engine stopped and cool, and carry it at least 10 ft away from the fuel spot before you pull the rope.
Husqvarna’s page lists 116 dB(A) sound power and 95.4 dB(A) at the operator’s ear, so I wear hearing protection from the first pull. It also lists vibration values of 5.66 m/s2 on the front handle and 8.93 m/s2 on the rear, and the manual warns that regular use can cause white finger. The manual calls the tool suitable for occasional operation and says that fingers that discolor, tingle or go numb mean stop work and see a doctor. Upkeep follows the manual, with the engine stopped, cool and the spark plug lead off: air filter, spark plug, cooling fins and bevel gear grease, then fresh fuel, and the tank emptied before storage. If my fingers tingle or go numb, I stop, as the manual says.
It fits you if you cut long open stretches where a pack swap would break the rhythm, and you are comfortable mixing fuel. Skip it if you want attachments, a blade for brush or quiet work next to the house.
FINAL VERDICT
Gas buyers facing grass that keeps going should start here. It starts, cuts and refuels on a routine. Take it if you accept the fuel, the noise and the tapping.
It is the gas trimmer I take to the far fence.
6. Milwaukee M18 FUEL 2825-21ST String Trimmer Kit Best Milwaukee
The Milwaukee 2825-21ST is the pick for readers who already own M18 tools. It puts an XC8.0 battery in the box, a QUIK-LOK trimmer attachment on a brushless M18 FUEL power head, and a swath you set to 14 in. or 16 in. by turning the cut-off blade.
WHY I CHOSE THIS ✓
I picked it because it serves the reader who wants one battery platform for the whole property. The XC8.0 pack and the QUIK-LOK system make sense if M18 tools already sit in your shed.
Milwaukee M18 FUEL 2825-21ST String Trimmer Kit Specs
Key Features:
- Adjustable swath: turn the line cut-off blade 180 degrees to switch between 14 in. and 16 in.
- XC8.0 battery in the kit: an 8.0Ah M18 pack that also fits Milwaukee’s M18 tools.
- QUIK-LOK attachment system: the maker lists an edger, an articulating hedge trimmer and a pole saw for the same power head.
- Two speeds: 0 to 4,900 rpm on low and 0 to 6,200 rpm on high, with a variable-speed trigger.
- Rear-mounted motor: Milwaukee’s page says it balances the tool.
I set the swath to 16 in. for the open edges and to 14 in. near the plum rows, and the change takes a turn of the cut-off blade: tool off, head stopped, battery out, gloves on, blade turned 180 degrees. The manual says low speed suits larger jobs where battery life matters, and high suits dense growth. It also says to keep at least 12 in. between the trimmer head and any body part, and to hold it just above the ground and swing it side to side. Long growth takes several passes.
The XC8.0 is an 8.0Ah M18 pack, and the manual says to wear the shoulder strap with larger packs; the strap is an accessory. I reload with 25 ft of 0.080 in. spiral line or 20 ft of 0.095 in., the lengths the manual gives.
Never use the tool as an edger. Milwaukee says to keep the head and line parallel to the ground.
Wear ANSI Z87.1 eye protection, hearing protection, gloves, heavy long pants, long sleeves and boots, and keep bystanders at least 50 ft away. Never fit a blade or a brush cutting wheel, and never use an attachment extension on this tool.
Before changing line, fitting an accessory or clearing the head, I switch off, wait for the head to stop and remove the battery, and only then touch the head. Milwaukee says the attachment’s gearcase needs up to 0.4 oz of Type Y grease after about 50 hours of use, and that the tool, battery and charger should come back for inspection after six months to a year. The trimmer attachment is bump fed, so I tap it on bare ground and never on stones. What annoyed me was the pull of the 8.0Ah pack at the end of a long edge, which the strap, an accessory, is there to answer.
It suits you if you own M18 tools and want the trimmer on the same battery. Skip it if you want an edger mode, an automatic feed or a published run time. Anyone outside the Milwaukee platform should look at a kit that matches the batteries they own. My head-to-head of Milwaukee 2825-21ST against EGO ST1623T settles which battery trimmer wins.
FINAL VERDICT
This kit suits the property owner who has already built a shed around M18 tools. The battery is big, the swath is adjustable and the attachments share the power head. Take it if you start from Milwaukee, and skip it if you start from nothing.
It is the trimmer for the M18 shed.
7. Greenworks 40V ST40L414 16-Inch String Trimmer Best 40V
The Greenworks 40V ST40L414 hangs from a shoulder strap, and Greenworks’ manual wants the carabiner about a hand’s width below your right hip. That detail tells you what kind of trimmer it is: a 16 in. brushless 40V trimmer with a 4.0Ah pack, built for a long cut and a strap on your shoulder. It also takes Greenworks attachments, which makes it a 40V platform choice as much as a trimmer.
WHY I CHOSE THIS ✓
It made the list because the 40V platform covers more than the trimmer. Greenworks says its 40V battery fits more than 75 of its tools, and the same power head takes the edger and the pole saw.
Greenworks 40V ST40L414 16-Inch String Trimmer Specs
Key Features:
- 16 in. swath with a 14 in. setting: the manual says 14 in. gives greater run time and 16 in. a larger cutting area.
- Brushless 40V motor: according to Greenworks, a brushless motor sits behind the 40V platform.
- Attachment capability: Greenworks lists an edger, a hedge trimmer, a pole saw, a cultivator and a blower for the power head.
- Two-speed switch and variable trigger: speed 1 is low and speed 2 is high.
- Shoulder strap and 0.095 in. line: the strap shares the load, and the heavier line stands up to fence-line weeds.
At 16 in. the head clears a wide strip, and I drop to 14 in. when run time matters more than width. I keep the 16 in. setting for open grass and the long fence line. The manual says to cut tall grass from the top down, no more than 8 in. in each pass, and to move the head in and out of the grass if the motor labors. The bump-feed head asks for a hit on firm ground to release line. Line only: Greenworks says never to install a blade.
Greenworks states up to 60 minutes on the 4.0Ah battery, with no conditions, and the charger takes about 120 minutes, according to the maker page. At 8.8 lb without the battery it is heavy for a battery trimmer, and the manual calls for the shoulder strap. I set the carabiner the way the manual describes.
Set the 14 in. swath for the last stretch of a pack, since Greenworks says it gives greater run time.
Wear safety glasses with side shields marked ANSI Z87.1, a face mask for dusty work, gloves and sturdy footwear, with no loose clothing, and keep bystanders, children and pets at least 50 ft away. Keep the guard in place.
Before clearing grass from the head, changing line or storing the tool, switch off, wait until the motor and head stop, then remove the battery, and only then touch the head. Charge between 39 and 104 F and store between 32 and 113 F. Do not spray water on the motor. The line is 0.095 in. nylon only, with no more than 15 ft loaded at a time, and the shape of the shaft, straight or curved, is not stated by Greenworks.
Take it if you want a 16 in. battery trimmer that grows into an edger or pole saw on the same battery, or if you already own Greenworks 40V tools. Skip it if you want a light trimmer or a blade for brambles.
FINAL VERDICT
The 40V choice for a large yard that wants attachments later. It carries a wide swath and a full-size battery, and the strap makes the weight manageable. Take it when the platform matters as much as the trimmer.
It is the 40V trimmer with a shoulder strap.
8. DeWalt FLEXVOLT 60V MAX DCST970X1 String Trimmer Kit Best DeWalt
The DeWalt DCST970X1 gives you a choice on the tool itself: a LO and HI switch, with a variable trigger inside each. LO extends run time for larger jobs, and HI suits heavier growth, according to DeWalt’s manual. If you want the best DeWalt string trimmer for a big yard, this 15 in. FLEXVOLT model is the one.
WHY I CHOSE THIS ✓
I kept it because the switch on the tool changes what the motor does. LO for the long run and HI for the thick patch is a rule I can apply in a few seconds.
DeWalt FLEXVOLT 60V MAX DCST970X1 String Trimmer Kit Specs
Key Features:
- LO and HI switch: LO is for longer run time on larger jobs, HI for heavier growth, with a variable trigger in each.
- FLEXVOLT pack: the trimmer needs a FLEXVOLT battery, and the included 60V MAX pack also works as a 20V MAX pack in DeWalt’s 20V MAX tools, according to DeWalt.
- 15 in. swath: a wide circle, and the manual warns that line past 15 in. harms the motor.
- Bump head with 0.080 in. line: the head also accepts 0.095 in. line, and spiral DeWalt line is required.
- Brushless gear drive: DeWalt calls the motor high-efficiency.
HI drew the pack down visibly faster than LO, as the manual says it will, so I flip to HI only at the thick corner. Against my old gas trimmer it starts with a squeeze of the lock-off lever and the trigger, with no choke and no rope. Along the wire fence I cut in short bites, since wire wears the line. DeWalt says to hold the guard at least 24 in. from your feet and tilt the trimmer no more than 30 degrees. I go through the LO and HI switch and the 3.0Ah pack in my review of the DeWalt DCST970.
The manual says HI shortens run time compared with LO, and the pack is 3.0Ah. For a large yard I plan a second pack from the start, so one is charging while the other works. Charging runs from 40 to 104 F, and the best pack life comes at 65 to 75 F.
Keep spare line in a sealed bag with a tablespoon of water, because DeWalt says line dries out.
Use ANSI Z87.1 eye protection, hearing protection and a face or dust mask, heavy long pants, gloves and rubber-soled footwear, and keep people and pets at least 100 ft away, the distance DeWalt’s manual gives. Never lock the trigger on, and never run the tool without the guard.
DeWalt says to blow dirt out of the vents with clean dry air at least once a week, with the tool off and the battery out and eye protection on, and never to use a hose or a pressure washer. A wet tool dries for at least 48 hours. The head uses DeWalt spiral line in 0.080 in. and also accepts 0.095 in., and other makers’ line can reduce performance or cause injury.
This one fits readers who already own FLEXVOLT batteries, or who want one pack that also serves DeWalt’s 20V MAX tools. Skip it if the job is large and you do not want to buy a second pack. Anyone who cannot keep a 100 ft clear zone should look elsewhere. I also weigh this kit against an EGO kit in DeWalt DCST970X1 against EGO MHC1603.
FINAL VERDICT
DeWalt owners with FLEXVOLT batteries get a 15 in. trimmer on their own packs. The switch gives you two modes and the pack gives you a platform. Take it if you will carry a spare pack.
It is the trimmer for the DeWalt battery shelf.
9. Echo SRM-3020T 30.5cc Gas String Trimmer Best Heavy-Duty
The Echo SRM-3020T is the heavy-duty gas trimmer here: a 30.5 cc two-stroke engine, a 20 in. swath and a 0.71 L tank, the largest engine, the widest swath and the largest tank among the trimmers on this page. It is my pick for the best heavy duty string trimmer on a large property. Echo lists a 2.07:1 ratio for the T model’s high-torque gear case.
WHY I CHOSE THIS ✓
I put it on the list because a large property sometimes needs the biggest engine. Twenty inches of swath and a big tank let you work an open field with fewer refuels, and the T model has a high-torque gear case.
Echo SRM-3020T 30.5cc Gas String Trimmer Specs
Key Features:
- 30.5 cc engine with a high-torque gear case: Echo lists 1.8 hp on its page and a 2.07:1 gear ratio for the T model.
- 20 in. swath: the widest circle on this page, so an open field takes fewer passes.
- Speed-Feed 500 LH head: tap it on the ground while it spins, and reload without taking it apart.
- D-loop handle and rubber engine mount: Echo lists them as its vibration measures.
- 5-year consumer warranty: Echo’s page gives five years for home use and two for commercial use.
On an open strip the 20 in. circle needs fewer passes than the 15 and 16 in. trimmers on this page, which is the reason I carry it. I did not expect the head to turn the moment the engine fires, so I lay the unit flat with the head clear of everything before I pull the rope. Echo’s start routine is the choke on cold start, the purge bulb until fuel flows and five more pushes, the throttle wide open and no more than five pulls. The tap-advance head feeds line as the manual describes, and the T model takes no blades.
Echo lists 12.3 lb dry without the cutter head in the manual and 13.9 lb dry with the head, both before fuel. The tank is 0.71 L, so I refuel at the end of a long run. Fuel is fresh 89 octane gasoline bought within the last 30 days, mixed 50:1 with the oil the manual names.
With the engine off and cool and the plug lead off, clean the grass and dust off the cylinder fins. Echo says build-up causes overheating, and the warranty excludes it.
Never run it indoors, in a shed or in a garage, even with the door open. Refuel outdoors with the engine stopped and cool, move away from the fuel spot before you start, and keep bystanders at least 15 m (50 ft) away.
The muffler and its cover get hot, so keep the exhaust area clear of dry grass. Before I clear wound material or change line, I stop the engine, wait for the head to stop and the engine to cool, and take off the spark plug lead. I put on eye and hearing protection, gloves, sturdy footwear and long pants before the first pull. Prolonged vibration can cause white finger, and the manual says to see a doctor if symptoms appear.
Go for it if you clear open ground and want the widest swath and biggest engine on this page. Skip it if you want a light tool, attachments, a blade for brush or quiet work near the house. Anyone sensitive to noise should pick a quieter type. I compare it with Husqvarna’s gas trimmer in Husqvarna 130L against Echo SRM-3020T.
FINAL VERDICT
Big, open property is the job this trimmer is built for. It has the engine, the swath and the tank to match the job. Take it if you can carry the weight and keep to the fuel rules.
It is the heavy trimmer for the far field.
How to Choose a String Trimmer for a Large Yard
A large yard asks three things of a trimmer: a wide swath, enough battery or fuel for a long stretch, and a weight you can carry to the end of the row. These seven factors decide that, in the order I check them.
Cutting Swath and the Number of Passes
Swath is the width of the circle the line cuts, and on a big yard it sets how many passes a job takes. The nine trimmers above run from 14 in. to 20 in., and several let you turn the line cut-off blade 180 degrees to pick between two widths. One manual says to use the narrow setting for greater run time and the wide setting for a larger cutting area.
| Swath | Passes across a 10 ft strip |
|---|---|
| 14 in. | About 9 |
| 15 in. | 8 |
| 16 in. | About 8 |
| 18 in. | About 7 |
| 20 in. | 6 |
I take the widest setting on open grass and drop to the narrow one at row ends and around posts, because a wide circle is harder to place beside a trunk. On a large yard the best cordless string trimmer is the one whose swath saves you passes without costing you the pack.
Pro Tip
Never lengthen the line past the cut-off blade on the guard. Several manuals warn that an overlong line overloads the motor and can void the warranty.
Run Time, Pack Size and Spare Packs
Makers state run time as minutes with one named pack and no stated conditions, and the figures here run from 45 minutes to 1.5 hours. I treat them as a best case and plan a large yard in blocks that end where a pack ends: a fence line, a tree row, an alley edge. The best battery powered string trimmer for big ground is a kit with a large pack or several packs. My roundup of the best battery string trimmer models ranks kits for yards of every size.
- Count the packs in the box. One kit holds four packs and a dual-port charger, while the others hold one.
- Read the basis. A maker’s minutes belong to the battery set it names, such as Makita’s pair of 18V packs, and the maker’s own conditions. One manual says the low speed lasts longer.
- Check the charging range. Manuals give a temperature range for charging, so a pack that comes off a hot yard waits.
- Price the second pack. A kit with a single pack usually needs a second battery on a large yard.
The best rated cordless string trimmer on a shelf can still be a poor match for a big yard if its run time is short, so I look at the maker’s run time and the pack count before anything else. Warranties on these kits run from three to five years on the tool, and several makers cover personal use only. If your property is smaller, my roundup of string trimmers for small yards lists lighter, easier-handling picks.
Paid Work
If you need a trimmer for paid work, read the warranty first. One maker gives two years for commercial use against five for a home owner, and others exclude commercial or rental use entirely.
Gas or Battery on Big Ground
Gas suits long runs where a pack swap would break the rhythm, and battery suits quiet work near the house. The best gas string trimmer for a large yard has a wide swath, a straight shaft and a tank that lasts. Fuel mix and starting steps differ by model, so follow the manual of the machine you buy: one maker’s manual gives 2 1/2 fl oz of its named two-stroke oil per US gallon for its 50:1 mix. My roundup of the best gas string trimmer models lays out power, weight and warranty for five picks.
| Question | Gas | Battery |
|---|---|---|
| What ends a long job | The tank; hours depend on load and tank size | The pack; makers state minutes with a named pack |
| Refilling | Mix fuel outdoors with the engine stopped and cool, then move away from the fuel spot to start | Swap a charged pack, or charge within the manual’s temperature range |
| Before touching the head | Stop the engine, wait for the head to stop, take off the spark plug lead | Release the trigger, wait for the head to stop, take out the battery |
| Where it runs | Outdoors only, never in a shed or garage | Outdoors, dry; never washed with a hose |
In a NIOSH sampling of 80 landscaping workers, noise and carbon monoxide exposure were significantly higher with fuel-powered string trimmers, leaf blowers and chainsaws than with battery versions (1). Where the grass lies far from the house, the best gas weed eater earns its noise. Beside the windows and the vegetable plot I choose battery.
Bump, Tap or Automatic Feed
A bump head releases line when you tap it on the ground while it spins, and a tap-advance head does the same at full speed. An automatic head senses wear and feeds line on its own, and one maker’s manual says it releases line when an end wears shorter than 7 in. Choosing between bump and automatic feed matters most on hard edges, where each tap throws gravel.
- Tap on bare ground or hard soil. One manual warns that tapping in tall grass can overheat the motor.
- In tall grass, when the head will not feed, switch off, wait for the head to stop and take out the battery (gas: let the engine cool and take off the spark plug lead), then touch the head and pull line out by hand. I rank trimmers for overgrown ground in my roundup of the best string trimmer for tall grass picks.
- Reloads differ: one head winds line with a button, and the others take a hand-wound piece cut to the length that head’s manual gives.
The gravel yard edge is where I want no tapping at all, because a bump on stones throws them at my boots and at the shed wall.
Weight, Shaft and Harness
Weight decides how long you can work, and makers publish it on different bases: without the battery, with the battery, dry without the head, or without fuel and guard. A lightweight claim only holds when every figure sits on one basis, and on a large yard weight is a trade against run time. In my best lightweight string trimmer roundup, I compare seven models by their stated weights.
Key Takeaway
Compare weights only on the same basis: with or without the battery, dry or with fuel, with or without the head.
A straight shaft reaches under fences and hedgerow bases, and the straight shaft that suits you is the one that balances at your height. Some manuals call for a shoulder strap or harness, and one asks for a 10 to 20 minute rest every hour.
In a laboratory test of grounds equipment, a grass trimmer gave the highest hand vibration, 3.5 to 5.8 m/s2 on a gloved hand (2). I use that as a reason to take a rest break at every row end. The best weed eater for a big property is the one you can still hold steadily at the end of the row.
Line, Attachments and Battery Platform
Every head takes only the line sizes its manual lists, and wire, rope or heavier line is never allowed: it overloads the motor or breaks off and flies. Attachment-capable power heads take an edger, a pole saw or other tools from the maker’s own list, and the list is short or long by model. Never assume that parts cross brands. For heavier growth, my roundup of the best string trimmer for thick weeds lists battery and gas models that take it on.
- A battery belongs to one maker’s platform, and the maker’s list of approved tools settles what fits, never the voltage alone.
- The best weed eater with attachments for you is the one whose list holds the tool you will actually use.
- The best string trimmer edger combo is one whose edger is in the kit, and in the kits above the edger is a separate purchase. My roundup of the best string trimmer for edging names the models with a real edge mode or an edger kit.
Among the best string trimmer brands, the useful question is which battery platform you already own, because a second tool on a pack you have costs less than a new platform. I read the manual of any tool before I buy a second pack for it. My roundup of the top string trimmer picks for every yard and budget includes several of these brands.
Safety Gear, Noise and Bystanders
A string trimmer throws what it hits. A review of US emergency-department data estimated 81,907 lawn trimmer injuries in ten years, and the eye alone took 42.5% of them (3). A case series of 26 eyes found an intraocular foreign body in 15, mostly metal and in 2 cases glass or stone (4). Wear eye protection that meets ANSI Z87.1 every time, together with hearing protection, long pants, boots and gloves.
Two petrol trimmer engines measured about 100 and 105 dB(A) at the operator, and the authors advise keeping operators 15 meters apart (5). NIOSH recommends an exposure limit of 85 dBA over an eight-hour day, with the time halved for each 3 dBA increase (6). Manuals give bystander distances of 50 ft (15 m) and, for two of these models, 100 ft.
- Keep the guard on, and never fit a blade or wire line to a head that is not rated for it.
- Keep the line off young trunks: manuals warn that bark is easily damaged.
- Never run a gas trimmer in a closed shed or a garage, even with the door open.
- Store battery packs dry and within the manual’s temperature range.
Safety First
Before you touch the head: switch off, wait for the head to stop, take out the battery (gas: take off the spark plug lead; corded: unplug), then clear it.
Before a long run I check the guard and the head for cracks, and I keep the pack out of the sun until I need it.
My Overall Verdict
I put nine trimmers through the work a large property gives: long edges, open grass and long jobs broken up by the rest breaks the manuals ask for. Three came out ahead on swath, pack and carry.
1. EGO Power+ MST1501 56V Multi-Head String Trimmer Kit Best Overall
The EGO MST1501 suits long tree rows and fence lines where one 5.0Ah battery has to carry the work.
2. Makita XRU15PT1 36V LXT Brushless String Trimmer Kit Best Premium
The Makita XRU15PT1 suits long jobs, with four packs so a pair is always charging.
3. Greenworks Pro 60V ST60L254 16-Inch String Trimmer Best Value
The Greenworks ST60L254 suits a large yard cut in pack-sized blocks without a premium kit.
The rest of the list fills real gaps: gas for long runs with no pack to swap, automatic feed for gravel edges and a heavy-duty engine for open fields. If I could take one trimmer to a big property, I take the EGO MST1501, because its 15 in. swath and 5.0Ah battery answer the problem a big yard poses. It is the best string trimmer for large yard work in my lineup.
Why EGO Power+ MST1501 56V Multi-Head String Trimmer Kit Might Be the Best Choice
I picked the EGO Power+ MST1501 56V Multi-Head String Trimmer Kit first because a large yard breaks small batteries and narrow swaths before it breaks anything else. Its 5.0Ah pack and 15 in. circle cut the two numbers that decide how long the job takes. My review of the EGO MST1501 covers its 15 in swath and 5.0Ah battery in daily work.
The trade-off is a bump-feed head that I tap on bare soil and never in tall grass, with a hand-wound reload.
What makes it my first pick for a large yard:
✓ 15 in. swath: fewer passes along every long edge.
✓ 5.0Ah battery in the box: a longer stretch before the first swap.
✓ Two speeds and a variable trigger: low for light work, high for dense growth.
✓ Attachment-capable power head: an edger, an extension pole and a pole saw can be added later.
✓ 5-year tool warranty: EGO’s term for the tool, with 3 years on the battery.

Safety Note: Read your manual first. A string trimmer or brush cutter throws debris with force, so clear stones, glass and wire from the area before you cut. Wear impact-rated eye protection with side coverage that meets ANSI Z87.1, hearing protection, gloves, heavy long pants, long sleeves and sturdy slip-resistant boots (steel-toe where your manual says so). Keep people and pets at least as far away as your manual says (50 feet in some manuals, 100 feet in others), and stop if anyone comes closer. Keep the correct guard fitted, use only the cutting attachments, handles and harness the maker approves for your exact tool, and never replace trimmer line with wire. A blade can kick sideways when it hits a stump or a thick stem, so fit the handlebar and harness your manual requires for blade work, hold both handles firmly and keep secure footing. Before you clear a jam, clean the tool or change line, a blade or an attachment, switch it off, wait for all movement to stop, then remove the battery, unplug the cord or disconnect the spark plug wire. Refuel a gas model outdoors with the engine off and cool, away from flames or sparks, and move away from the fueling spot before starting, as far as your manual says (often 10 to 30 feet); never run it in a garage, shed or other closed space. For a battery model, use only the maker’s battery and charger, charge it within the temperature range in your manual and never use a damaged or swollen pack. For a corded model, use a GFCI outlet, keep the cord clear of the cutting line and avoid wet conditions.
