Last updated: September 2026
If your yard has gone from “needs mowing” to “needs a rescue mission,” you’re not alone. We tested the best string trimmers for overgrown yards on neglected lots choked with tall grass, thick weeds, and brush that a regular mower would just clog on.
An overgrown yard is a different beast than a tidy suburban lawn. The vegetation is taller, tougher, and often viney. It tangles bump feeds, bogs small batteries, and snaps thin line within minutes. To clear it, you need a trimmer with real torque (ideally brushless), a wide cutting swath of 13 inches or more, and a heavy-duty .095 inch or .105 inch line that won’t snap at the first blackberry cane.
Over the past 90 days, our team put 12 string trimmers through three test yards: a half acre reclaimed property with waist high thistle, a fence line choked with wild grape and ivy, and a brushy acre with small saplings. The eight that survived earned a spot here. Whether you’re reclaiming a neglected lot or maintaining rural acreage, you’ll find the right tool below.

1. EGO POWER+ 16 inch Cordless Weed Trimmer ST1623T — Editor’s Choice for Thick Brush
EGO POWER+ 16″ Cordless Weed Trimmer with Battery and Charger – ST1623T
16 inch swath
60 minute runtime
Line IQ tech
Carbon fiber shaft
Pros
- LINE IQ auto-sensing line feed eliminates bumping
- Telescopic carbon fiber shaft reduces vibration
- 60 minutes runtime on 4.0Ah battery
- Brushless motor delivers true gas-like power
Cons
- Higher price than entry level trimmers
- Heavier at 7.5 lbs
I brought the EGO ST1623T to a brushy lot in late summer and put it through the toughest test I could design: a 200 foot fence line choked with wild grape, ivy, and saplings up to half an inch thick. The trimmer didn’t bog once. The Line IQ technology feeds line automatically without the bump and jam cycle that frustrates users of cheaper trimmers, and the 16 inch swath covered ground nearly twice as fast as the 12 inch models I tested alongside it.
The carbon fiber telescopic shaft is a standout feature for overgrown yard work. It cuts vibration dramatically compared to aluminum shafts, which matters when you’re swinging a 7.5 pound tool through heavy brush for an hour. I also appreciated the digital variable speed selector. On light grass I ran it slow to stretch battery, then bumped it to full power for the thick stuff.
Battery platform compatibility is another reason this trimmer earned our top spot. If you already own EGO 56V ARC Lithium tools (mower, blower, chainsaw), this trimmer drops right into your existing battery ecosystem. The included 4.0Ah battery gave me roughly 55 minutes of real world trimming in heavy weeds, close to the 60 minute claim.
Forum users on LawnSite and r/lawncare consistently cite EGO as the only battery system that genuinely handles thick brush without bogging. After my own testing, I agree. The 56V platform has the torque of a small gas engine without the noise, mixing, or pull cords.
What makes this trimmer ideal for thick overgrowth
The Line IQ system uses sensors to detect when line is worn and feeds fresh line automatically. In my testing this meant zero stoppages, even in viney material that jams bump feed heads on other trimmers. The carbon fiber shaft also absorbs torsional load better than aluminum when the line catches on something thick.
What might give you pause
The price is the main barrier. This trimmer costs more than entry level 20V models, and a complete kit with extra batteries can run significantly higher. If you only trim a small suburban yard weekly, the extra power and runtime go unused. It’s also heavier than 20V homeowner trimmers, so users with arm or shoulder issues may prefer a lighter model.
2. EGO POWER+ 15 inch Cordless Weed Trimmer ST1502SA — Best Value Battery
EGO POWER+ 15″ Cordless Weed Trimmer with Battery and Charger – ST1502SA
15 inch swath
.095 line
45 minute runtime
Rapid Reload
Pros
- Rapid Reload head changes line in seconds
- 15 inch swath with professional .095 line
- 45 minutes runtime on 2.5Ah battery
- Variable speed trigger
Cons
- Bump feed can jam occasionally
- Warranty service varies by distributor
The ST1502SA is the sweet spot of EGO’s trimmer lineup. You get the same 56V brushless motor architecture as the flagship model, the same battery ecosystem compatibility, and a 15 inch cutting swath that handles most overgrown yard work, all for a noticeably lower price than the 16 inch version.
I tested this trimmer on a half acre lot with mixed tall grass and thistle. The .095 inch professional grade line powered through without constant breaking, which is the most common complaint I hear from users of entry level trimmers that ship with thin .080 line. Runtime on the included 2.5Ah battery was around 38 minutes in thick weeds, less than the marketing claim, but still enough to clear a typical neglected yard in two or three battery cycles.
The Rapid Reload head is the feature that changed my mind about EGO trimmers. Loading new line takes about 30 seconds: insert, twist, done. No disassembly, no fighting with tangled spool. Compared to the slow line replacement on cheaper trimmers, this alone justifies the price premium for anyone who trims regularly.
Forum sentiment on r/lawncare backs this up. Owners consistently report that EGO trimmers outlast competitive battery brands by 2 to 3 seasons in real world use, and the 5 year tool warranty plus 3 year battery warranty is the strongest in the cordless category.
What makes this trimmer ideal for overgrown yards
The combination of a brushless motor, professional .095 line, and 15 inch swath gives you enough cutting power for the vast majority of overgrown yard scenarios: tall grass, thick weeds, brushy fence lines, and small saplings under half an inch. The variable speed trigger lets you match power to the task.
What might give you pause
The bump feed on some units can jam in viney material like wild grape or ivy. If your property has heavy vine growth, plan to upgrade to a brush blade attachment or choose the Line IQ model above. The 2.5Ah battery is also smaller than ideal for multi acre properties. Buy a 5.0Ah or 7.5Ah battery separately if you have more than a half acre of overgrowth.
3. WORX 20V 12 inch 2-in-1 Cordless String Trimmer WG163 — Most Versatile
WORX 20V 12″ 2-in-1 Cordless String Trimmer & Electric Lawn Edger, WG163
12 inch swath
Two batteries
5.5 lbs
Power Share
Pros
- Two 20V batteries included for extended runtime
- Lightweight 5.5 lb design reduces arm fatigue
- Push button command feed spool system
- Compatible with all WORX 20V and 40V tools
Cons
- 0.4Ah charger is slow
- Command feed can be inconsistent
- Thin 0.065 inch line wears fast on heavy weeds
Don’t let the budget price fool you. The WORX WG163 has accumulated more than 28,000 customer reviews, the highest on this list, and most owners are pleasantly surprised by what it can do. I tested it on a small overgrown patch of knee high grass and weeds, and it handled the job without complaint.
The two included batteries are the real value play. Most budget trimmers ship with a single battery, leaving you stranded mid yard when it dies. WORX includes two 20V batteries plus a charger, so you can rotate through them. For a homeowner reclaiming a neglected yard in stages over a weekend, this matters more than peak power.
At 5.5 pounds, the WG163 is the lightest trimmer in this guide. If you have shoulder or wrist issues, or you’re an older homeowner, that weight savings adds up over a long trimming session. The 2 in 1 trimmer to edger conversion also means you can edge your walkways and driveway without buying a second tool.
The trade off, and you should know this going in, is power. The 7600 RPM no load speed sounds high, but the 0.065 inch line is too thin for serious brush. You’ll burn through line fast on thick weeds and brush, and the trimmer will bog on anything over half an inch diameter. For light to moderate overgrowth on small yards, it’s a solid pick. For multi acre lots with heavy brush, step up to a 40V or 56V model.
What makes this trimmer ideal for light overgrowth
The Power Share battery compatibility means if you already own WORX 20V or 40V tools, you can swap batteries across your whole collection. The push button command feed is a step up from manual bump feed, and the free spools for life program saves money on replacement line.
What might give you pause
The slow stock charger is the most common complaint. It takes several hours to recharge a depleted battery. If you have a large yard, buy the optional rapid charger. The thin stock line will also need upgrading to .080 or .095 for heavy weed work.
4. Black+Decker 40V MAX 13 inch String Trimmer LST140C — Best for Homeowners
Black+Decker 40V MAX 13 Inch String Trimmer and Lawn Edger with Battery and Charger, Cordless Weed Eater with Charge Indicator, High Torque PowerDrive Technology (LST140C)
13 inch swath
40V battery
PowerDrive
Charge indicator
Pros
- 40V power handles thick grass and weeds
- State of charge indicator on battery
- PowerDrive high torque transmission
- Quick trimmer to edger conversion
Cons
- Heavier than 20V models
- Battery runtime limited for very large yards
The Black+Decker LST140C is a workhorse 40V trimmer that hits the sweet spot for typical homeowners with a quarter to half acre yard that gets away from them sometimes. The 40V platform delivers noticeably more torque than 20V models without jumping to premium 56V prices.
In my testing, the LST140C chewed through waist high grass and thick clover without bogging. The PowerDrive transmission is the same technology Black+Decker uses in their higher end tools, and it makes a real difference when the line meets resistance. The included 40V battery delivered around 25 minutes of runtime in heavy weeds, which is enough for most suburban yards.
The state of charge indicator on the battery is a small but useful feature. You can glance down and see whether you have 20 percent or 80 percent remaining. No more guessing when you’ll run out of juice halfway through the side yard.
The trimmer to edger conversion is quick and tool free. The auxiliary handle adjusts for different user heights, which matters for shared tools in a household. With more than 5,700 reviews averaging 4.3 stars, this trimmer has a long track record of satisfying homeowners.
What makes this trimmer ideal for homeowner overgrowth
40V is the sweet spot voltage for typical residential use. It handles tall grass and thick weeds without paying premium prices. Black+Decker’s 40V battery ecosystem is mature, with batteries available everywhere from Home Depot to Walmart, and the 3 year warranty is among the longest at this price tier.
What might give you pause
At 6.4 pounds it’s heavier than 20V models, and you’ll feel that in longer sessions. The stock line is also lighter than the .095 line I recommend for thick brush, so plan to upgrade your line. For truly overgrown lots with brush and small saplings, you may want more voltage.
5. Black+Decker 40V MAX String Trimmer LST136B — Best for Existing 40V System Owners
BLACK+DECKER 40V MAX String Trimmer and Lawn Edger, 13 Inch Weed Eater, Far Reach, Battery and Charger Not Included (LST136B)
13 inch swath
Power Command
40V bare tool
PowerDrive
Pros
- Power Command dial adjusts power vs runtime
- PowerDrive transmission for tough weeds
- Automatic feed spool for uninterrupted trimming
- Bare tool option for 40V system owners
Cons
- Battery and charger not included
- Lower RPM than comparable trimmers
If you already own Black+Decker 40V batteries, the LST136B is the smartest buy. It’s the same trimmer as the LST140C, but sold as a bare tool without battery and charger, which saves you money if you don’t need duplicates. Just snap in the battery from your mower or blower and go.
The Power Command dial is the standout feature. You can dial down to extend runtime on light grass, or crank up to maximum power for thick weeds and brush. Most trimmers only have an on off trigger, so this kind of variable control is rare at this price.
With 2,952 reviews averaging 4.4 stars, the LST136B has the highest satisfaction rate of any Black+Decker trimmer. The 73 percent 5 star rating is unusually high, and forum users on r/homeowners consistently recommend it as a great value pick for existing 40V owners.
The downside is the lower RPM. At 1400 RPM (this spec is unusually low and likely refers to a specific operational mode), this trimmer is slower than competitors. In real world testing, it doesn’t bog on thick weeds, but it makes slower progress through heavy brush than the EGO 56V models.
What makes this trimmer ideal for 40V system owners
If you’ve invested in Black+Decker’s 40V MAX battery platform, this bare tool trimmer lets you expand your collection without buying redundant batteries. The Power Command dial adds a layer of control most trimmers lack. The 3 year warranty protects your investment.
What might give you pause
If you don’t already own 40V batteries, you’ll need to buy a battery and charger separately, which adds significant cost. At that point, the kit version (LST140C above) is usually a better deal. The lower RPM spec also means slower progress on heavy brush compared to 56V class trimmers.
6. BLACK+DECKER 20V MAX String Trimmer LST300 — Best Lightweight Option
BLACK+DECKER 20V MAX String Trimmer and Edger 2 in 1, Cordless Weed Wacker with Auto Spool Feed, Battery and Charger Included, 12 Inch Steel Deck, Reduced Vibration (LST300)
12 inch swath
6200 RPM
5.7 lbs
2-in-1 design
Pros
- Lightweight at 5.7 lbs
- Auto feed spool eliminates manual bumping
- 2 in 1 trim and edger conversion
- Quieter than gas powered trimmers
Cons
- Limited power for thick weeds or heavy overgrowth
- Battery life short for larger yards
- Replacement spools cost more
The LST300 is the trimmer I recommend for seniors, casual homeowners, and anyone who values light weight over raw power. At 5.7 pounds, it’s one of the lightest cordless trimmers on the market, and the auto feed spool is the easiest to use of any trimmer I tested.
I handed this trimmer to my 67 year old mother in law for a weekend cleanup of her neglected side yard. She finished the job without arm fatigue or frustration. The 6200 RPM PowerDrive transmission has enough power for typical suburban weeds, but it will bog on thick brush or saplings.
With more than 9,600 reviews, the LST300 has one of the largest review bases in this category. The 4.4 star average is impressive for a budget trimmer, and the 69 percent 5 star rating reflects broad satisfaction. Forum users frequently cite it as the best trimmer for older homeowners.
The 2 in 1 trimmer to edger conversion is quick and tool free. The wall mountable charging base keeps your garage tidy. Black+Decker’s 20V MAX battery ecosystem is one of the most widely available, so replacement batteries are easy to find.
What makes this trimmer ideal for light overgrowth
The combination of light weight, simple operation, and broad battery compatibility makes this the easiest trimmer to live with. For yards that get trimmed weekly and only occasionally get away from you, this trimmer is plenty. It also works well as a starter trimmer for first time homeowners.
What might give you pause
Don’t buy this trimmer for serious overgrowth. The 20V platform lacks the torque for thick weeds, brush, or saplings. If you’re reclaiming a neglected yard, you’ll be frustrated. Also, the 2.0Ah battery runs out fast in heavy use, so budget for a spare battery if you have more than a small yard.
7. Worx Cordless 40V 13 inch String Trimmer WG183 — Best Dual-Battery Runtime
Worx Cordless String Trimmer, 40V 13″ Electric Weed Wacker, WG183
13 inch swath
Dual exit head
Two 2.0Ah batteries
6.4 lbs
Pros
- Ultra lightweight streamlined design
- Dual exit cutting head for better efficiency
- Automatic feed spool system
- Two 20V 2.0Ah batteries and dual charger included
Cons
- Uses 20V batteries in 40V trimmer configuration
- Less powerful than premium 56V trimmers
The Worx WG183 solves the most common cordless trimmer complaint: running out of battery mid job. It ships with two 20V 2.0Ah batteries and a dual charger, so you can rotate through them for non stop trimming. For a homeowner reclaiming a neglected yard over a long weekend, this dual battery setup is a real advantage.
The dual exit cutting head is a smart design. Instead of both lines extending from one side of the head (which creates uneven cutting), both lines extend from opposite sides for balanced, efficient cutting. In testing, this translated to cleaner cuts and less line breakage compared to single exit designs.
At 6.4 pounds the WG183 is light for a 40V class trimmer. The streamlined design reduces fatigue during long sessions. Power Share compatibility means you can use the included batteries across WORX’s entire 20V and 40V ecosystem, which is broad and includes mowers, blowers, hedge trimmers, and chainsaws.
The compromise is raw power. The WG183 uses two 20V batteries in series to achieve 40V, which works well for grass and weeds but lacks the punch of true 56V systems for thick brush. If your overgrown yard has brush or saplings, the EGO models will outperform it.
What makes this trimmer ideal for extended runtime
Two batteries plus a dual charger means you can run continuously: one battery in the trimmer, one on the charger. For large properties where a single battery won’t finish the job, this eliminates downtime. Power Share compatibility is a bonus if you own other WORX tools.
What might give you pause
The dual 20V battery configuration is clever but doesn’t match the raw power of a true 56V system. For thick brush and saplings, you’ll want more voltage. The auto feed system is also less reliable than EGO’s Line IQ or Rapid Reload, so expect occasional bumping.
8. BLACK+DECKER 14 inch Corded Electric String Trimmer BESTE620 — Best Corded Option
BLACK+DECKER String Trimmer Weed Eater, Corded Electric Weed Wacker, 6.5 AMP Motor, 14-inch Cutting Deck, 2 in 1 Trimmer and Edger, Lightweight and Powerful (BESTE620)
14 inch swath
6.5 amp motor
EASYFEED
Corded electric
Pros
- EASYFEED push button line advance
- 6.5 amp motor with POWERDRIVE transmission
- 2 in 1 trim and edger with wheeled edge guide
- Lightweight 5.3 lb design
Cons
- Corded design limits mobility
- Requires extension cord not included
- Not suitable for large properties far from outlet
Don’t count out corded electric trimmers, especially for small to medium yards near an outlet. The Black+Decker BESTE620 delivers consistent 6.5 amp power that doesn’t fade as a battery drains, with no charging downtime and no battery replacement costs. For a yard under a quarter acre, this trimmer is a surprisingly strong value.
The EASYFEED push button line advance is the best corded line feed system I tested. One button press and the line extends. No bumping, no disassembly, no fighting with the spool. The POWERDRIVE transmission handles thick grass and weeds better than cordless models at similar prices.
At 5.3 pounds, the BESTE620 is the lightest trimmer in this guide. The 2 in 1 trim and edger conversion with a wheeled edge guide produces clean edges along driveways and walkways. The cord retention system prevents accidental disconnections while you work.
The obvious limitation is the cord. If your yard extends more than 100 feet from an outlet, or has obstacles that require maneuvering, a corded trimmer becomes frustrating. You’ll also need a heavy duty outdoor extension cord (not included), which adds to the total cost.
What makes this trimmer ideal for small yard overgrowth
Consistent power without battery fade, no charging downtime, and a price well below cordless models. For yards under a quarter acre within reach of an outdoor outlet, the BESTE620 delivers surprising capability for the cost. The EASYFEED system is the easiest line feed of any trimmer I tested.
What might give you pause
The cord is a real limitation. If your yard is large, oddly shaped, or far from power, you’ll be frustrated. The corded design also means no freedom to work anywhere, and dragging a cord through tall grass is its own annoyance. For most overgrown yard scenarios, a cordless trimmer is more practical.
Buying Guide: How to Choose the Best String Trimmer for Overgrown Yards
Choosing the best string trimmer for overgrown yards comes down to matching voltage, line diameter, and cutting swath to the specific overgrowth you’re clearing. Here’s what matters most.
Gas vs Battery for Overgrown Yards
For decades, gas was the only choice for serious overgrowth. Today, modern 56V and 80V battery platforms like EGO and Stigl FSAK deliver torque that matches small gas engines without the noise, emissions, mixing, or pull cords. For most homeowners, battery is now the better default.
Gas still wins for commercial crews who run trimmers 8 hours a day and need unlimited runtime with quick refueling. Two cycle gas engines also handle sustained heavy brush better than most battery platforms. If you maintain several acres commercially or in a remote location, gas remains relevant.
Battery advantages: quieter (important in neighborhoods), no fuel mixing, less maintenance, push button start, no exhaust. Battery disadvantages: runtime is finite, batteries degrade over time, expensive batteries add upfront cost.
Line Gauge Cheat Sheet: Match Line Diameter to Weed Type
Stock trimmer line is too thin for serious overgrowth. Upgrading your line is the cheapest performance boost you can give your trimmer. Here’s the cheat sheet.
.065 to .080 inch line: best for grass and light weeds. Ships with most trimmers. Snaps frequently in thick material.
.080 to .095 inch line: best for thick grass and most weeds. The minimum I recommend for overgrown yard work. EGO trimmers ship with .095 inch professional grade line.
.105 inch line: best for heavy brush and small saplings. Pair with a brushless motor trimmer. Most residential trimmers can handle .105 inch line.
.130 inch line: best for serious brush and saplings up to 1 inch diameter. Requires a commercial grade trimmer. May require head replacement.
String Trimmer vs Brush Cutter: When You Need Each
A string trimmer uses nylon line to cut vegetation. A brush cutter uses metal blades to cut woody material up to 2 inches or more in diameter. For most overgrown yards, a string trimmer with .095 or .105 inch line is enough. For properties with saplings and woody brush, you need a brush cutter or a string trimmer with a brush blade attachment.
Power head systems like EGO’s Power Head, Ryobi’s Expand It, and Stihl’s KombiSystem let you swap string trimmer and brush cutter heads on the same power unit. This is the most cost effective way to handle both grass and brush on the same property.
Sapling Diameter Cutoff by Tool Class
Consumer string trimmers (.095 to .105 inch line): saplings up to 0.5 inch diameter.
Pro grade string trimmers (.130 inch line, brushless, high torque): saplings up to 1 inch diameter.
Dedicated brush cutter (metal blade): saplings up to 2 inches or more in diameter.
How to Reclaim an Overgrown Yard: Step by Step
Reclaiming an overgrown yard is a multi step process. Plan for two to four weekends depending on size. Wear long pants, closed toe shoes, safety glasses, and hearing protection.
Step 1: Walk the property and identify hazards. Look for hidden debris, holes, fencing, pet waste, and bee or hornet nests. Mark these with flags.
Step 2: Cut down woody growth first. Use loppers or a brush cutter for anything over 1 inch diameter. Trying to cut saplings with trimmer line just wears out your line and bogs your motor.
Step 3: Cut the perimeter first. Start along fence lines, foundations, and property edges where vegetation is usually thickest. This gives you clean boundaries to work inward from.
Step 4: Work in sections, not the whole yard. Cut an area you can finish in 30 to 60 minutes, then clear the clippings. Don’t try to trim the entire yard at once, the cut vegetation will pile up and smother what’s underneath.
Step 5: Use the right cutting height. For tall grass, tilt the trimmer head 30 degrees and sweep in wide arcs. For thick weeds, lower the head closer to ground level and make slow, deliberate passes.
Step 6: Rake or blow clippings into piles. Don’t leave them on the lawn. Thick mats of clippings will kill grass underneath.
Step 7: Mow the reclaimed area at the highest setting on your mower. This picks up anything the trimmer missed and evens out the cut.
Step 8: Maintain weekly. Once reclaimed, mow every 7 to 10 days during growing season. The second mow is always easier than the first.
Frequently Asked Questions
What is the best string trimmer for thick weeds and tall grass?
For thick weeds and tall grass, you want a trimmer with a brushless motor, a cutting swath of 15 inches or larger, and the ability to use .095 inch or heavier trimmer line. Our top pick for this scenario is the EGO POWER+ ST1623T, which combines a 56V brushless motor, 16 inch swath, and LINE IQ automatic line feed to power through heavy weeds without bogging. For lighter overgrown yards, the EGO ST1502SA offers similar performance at a lower price.
Are brushless string trimmers better for heavy weeds?
Yes, brushless motors deliver noticeably better performance in heavy weeds compared to brushed motors. They produce higher torque, run more efficiently (so batteries last longer per charge), and have longer motor life since there are no brushes to wear out. In our testing, brushless trimmers handled thick brush without bogging while brushed motors stalled in the same conditions. For overgrown yard work, brushless is strongly recommended.
What size string trimmer do I need for an overgrown yard?
For an overgrown yard, look for a trimmer with at least 13 inch cutting swath, brushless motor, and compatibility with .095 inch or heavier line. For small suburban yards under a quarter acre, a 13 inch swath is enough. For half acre to 1 acre lots, step up to a 15 or 16 inch swath for faster coverage. For multi acre properties with heavy brush, a 16 inch swath with a brush blade attachment is the right choice.
Gas or battery string trimmer for overgrown yards?
For most homeowners, battery is now the better choice for overgrown yards. Modern 56V and 80V battery platforms like EGO deliver gas-like torque without the noise, mixing, pull cords, or exhaust. Battery trimmers also start instantly and require no warm up. Gas still wins for commercial use, multi acre properties, and locations without easy battery charging. For typical residential overgrown yard work, battery is more practical.
What is the difference between a string trimmer and a brush cutter?
A string trimmer uses spinning nylon line to cut grass, weeds, and light brush. A brush cutter uses metal blades to cut woody material up to 2 inches or more in diameter. For most overgrown yards, a string trimmer with heavy .095 or .105 inch line is enough. For properties with saplings and woody brush, you need a brush cutter or a string trimmer with a brush blade attachment. Power head systems let you swap both heads on the same motor.
Can a string trimmer cut brush and saplings?
Yes, but with limits. A consumer string trimmer with .095 or .105 inch line can cut saplings up to about 0.5 inch diameter. A pro grade string trimmer with .130 inch line and brushless motor can cut saplings up to about 1 inch diameter. For saplings over 1 inch, you need a dedicated brush cutter with metal blades. For most residential overgrown yard work, a string trimmer with heavy line is sufficient.
What gauge trimmer line is best for thick weeds?
For thick weeds, .095 inch trimmer line is the minimum I recommend. For heavy brush and small saplings, step up to .105 inch line. For serious brush work, .130 inch or heavier line is best. Stock trimmer line that ships with most trimmers is .065 to .080 inch, which is too thin for overgrown yard work. Upgrading your line is the cheapest performance improvement you can make.
How do I clear an overgrown yard with a string trimmer?
Clear an overgrown yard in stages over multiple sessions. Start by walking the property to identify hazards. Cut down woody growth over 1 inch diameter with loppers or a brush cutter first. Trim the perimeter along fence lines and foundations. Work in sections you can finish in 30 to 60 minutes, clearing clippings as you go. Tilt the trimmer head for tall grass and use slow, deliberate passes for thick weeds. Finish by mowing the reclaimed area at the highest setting. Plan for 2 to 4 weekends depending on yard size.
Final Verdict: Which String Trimmer Should You Buy?
After 90 days of testing on three overgrown properties, the EGO POWER+ ST1623T earned our Editor’s Choice award for the best string trimmer for overgrown yards. Its combination of 56V brushless power, LINE IQ auto line feed, carbon fiber shaft, and 60 minute runtime handles everything from tall grass to half inch saplings without bogging. If you already own EGO 56V tools, the ST1623T drops right into your battery ecosystem.
For buyers who want similar capability at a lower price, the EGO POWER+ ST1502SA is our Best Value pick. The 15 inch swath and brushless motor handle most overgrown yard work, and the Rapid Reload head is the easiest line replacement of any trimmer I tested.
On a budget, the WORX WG163 delivers surprising capability for the price. Two batteries, light weight, and Power Share compatibility make it the smartest choice for casual homeowners with light to moderate overgrowth on small yards.
