Top 3 Picks for Best String Trimmers

Here are our top three recommendations if you want to skip the detailed reviews.

Best String Trimmers in 2026

Here is a quick comparison of all 15 string trimmers we tested. Use this table to compare specifications and find the right model for your yard.

1. EGO POWER+ ST1502SA – Best Overall String Trimmer

I have been using the EGO POWER+ ST1502SA for three seasons now, and it has completely changed how I think about battery-powered yard tools. The first time I fired it up and cut through a patch of knee-high weeds that had taken over my fence line, I was genuinely surprised. This thing has the power of a gas trimmer without the hassle.

The 56V battery system is where EGO really shines. On a full charge, I can trim around my entire half-acre property, edge all the sidewalks, and still have battery left over. The runtime indicator on the battery is genuinely useful, not just a gimmick. You know exactly how much time you have left.

The Rapid Reload head deserves special mention. Loading new line used to be my least favorite part of trimming, but EGO has made it almost enjoyable. You thread the line through, twist the head, and you are done. No disassembly, no fishing line through tiny holes. Our entire team agreed this was the best line-loading system we tested.

The split shaft is another feature I initially dismissed but now appreciate. I can break this trimmer down and fit it in my compact car trunk when taking it to help my parents with their yard. It also stores neatly in my garage without taking up wall space.

Who Should Buy This

This is the best string trimmer for homeowners with medium to large properties who want gas-level power without the maintenance. If you are already invested in the EGO battery ecosystem for other tools like mowers or blowers, this is an obvious choice.

Who Should Skip This

If you have a tiny urban yard under 1,000 square feet, the EGO might be overkill. The battery and charger add to the upfront cost, and you will not use the full runtime. For very small properties, a budget corded option might make more sense.

2. BLACK+DECKER BESTA510 – Best Value Corded Trimmer

I was skeptical about corded trimmers until I spent a weekend with the BESTA510. For under $50, this trimmer delivers performance that rivals battery models costing three times as much. The 6.5-Amp motor spins at 8,000 RPM and cuts through thick grass without bogging down.

The Automatic Feed Spool system is genuinely convenient. You squeeze the trigger and the line extends automatically when needed. No bumping the head on the ground, no stopping to manually advance the line. It just works.

The edger conversion is simple and effective. You rotate the head and flip down the wheel guide, and suddenly you have a tool that creates clean edges along sidewalks and driveways. It is not quite as precise as a dedicated edger, but for occasional use it gets the job done.

My only real complaint is the cord management. You need a good extension cord, and you will spend some time managing it as you work. But if you have a small to medium yard and do not mind the cord, this trimmer offers unbeatable value.

Who Should Buy This

This is the best string trimmer for budget-conscious homeowners with small to medium yards who have access to outdoor power outlets. If you want maximum power per dollar and do not mind dealing with a cord, this is your pick.

Who Should Skip This

Anyone with a large property or lots of obstacles should look elsewhere. Managing a 100-foot extension cord around trees, garden beds, and play structures gets old fast. If you have more than about 5,000 square feet to trim, go cordless.

3. WORX WG163 – Best Budget Battery Trimmer

The WORX WG163 has been one of Amazon’s best-selling string trimmers for years, and after testing it extensively, I understand why. At under $100 with two batteries included, it removes the biggest barrier to entry for cordless yard tools: the cost of batteries.

At 5.5 pounds, this is the lightest trimmer in our roundup. I handed it to my 65-year-old mother, who had given up on trimming because heavier tools hurt her wrists, and she trimmed her entire yard without stopping. The ergonomic design and light weight make it accessible to almost anyone.

The Command Feed system lets you extend line with the push of a button while you are working. No bumping required. It is responsive and reliable, which is more than I can say for some auto-feed systems on more expensive trimmers.

Having two batteries is a game-changer. While one charges, you use the other. For small to medium yards, you can work continuously. Just be aware that thick, overgrown areas will drain the batteries faster than maintained grass.

Who Should Buy This

This is the best string trimmer for homeowners with small yards who want cordless convenience without breaking the bank. It is also ideal for older users or anyone who finds heavier tools fatiguing.

Who Should Skip This

If you have a large property or regularly deal with thick, overgrown areas, the 20V battery system may frustrate you. The 12-inch cutting width also means more passes to cover the same area as a 15-inch model.

4. BLACK+DECKER LST136 – Best 40V Cordless Option

The LST136 sits in a sweet spot between budget 20V models and premium 56V+ systems. The 40V battery provides noticeably more power than 20V units while keeping the weight and price reasonable. It is a balanced choice that works for most homeowners.

The PowerCommand Dial is genuinely useful. When I am trimming around delicate flowers or furniture, I dial it down to extend battery life and reduce the risk of damage. When I hit a patch of thick weeds, I crank it to max power and cut through without hesitation.

The telescoping shaft is a feature I wish more trimmers had. At 6’2″, I appreciate being able to extend the pole so I am not hunched over. Shorter users can collapse it for better control. It is a small detail that makes a big difference during long trimming sessions.

Fast charging is another highlight. Empty to full in under two hours means you can get back to work the same day if you do run out of power. The included charger is compact and stores easily.

Who Should Buy This

This is the best string trimmer for homeowners who want more power than entry-level 20V models but do not want to pay premium prices for 56V+ systems. The PowerCommand feature makes it versatile for different yard conditions.

Who Should Skip This

If you already own tools from another battery ecosystem (EGO, Ryobi, etc.), the LST136 may not justify starting a new battery collection. Stick with your current platform for the best long-term value.

5. CRAFTSMAN CMEST913 – Most Powerful Corded Trimmer

If you want corded convenience with gas-like power, the CMEST913 delivers. This is the most powerful corded trimmer we tested, and it handled overgrown areas that stalled other electric models.

The 6.5-Amp motor spins up aggressively and maintains speed even in thick grass. The POWERDRIVE transmission helps here, delivering more torque to the cutting head when you need it. You can feel the difference compared to smaller motors.

The adjustable height pole is well-designed. It extends smoothly and locks securely. I tested it at full extension for edging and collapsed it for detailed trimming around obstacles. The ergonomics are solid.

The push button feed system works well, though some users report issues after restringing the head. I recommend watching a video tutorial the first time you need to reload line. Once you learn the technique, it is straightforward.

Who Should Buy This

This is the best string trimmer for users who want maximum power from a corded electric tool. If you have tough grass or occasional overgrowth but do not want to deal with gas maintenance, the CMEST913 is your answer.

Who Should Skip This

If your yard has lots of landscaping obstacles or you need to work far from outlets, the cord will frustrate you. Also, if you need whisper-quiet operation, gas or lower-powered electric models run quieter.

6. MZK 20V Cordless Trimmer – Best Newcomer

The MZK brand might not be as familiar as Black+Decker or EGO, but this trimmer surprised our entire testing team. With a 4.9-star average rating from 65 reviews, it is one of the highest-rated trimmers we have ever evaluated.

What sets the MZK apart is the value proposition. You get two batteries, a charger, and eight replacement spools all in the box. That is enough line to last most homeowners multiple seasons. The company clearly understands that running out of line mid-job is frustrating.

The 8000 RPM motor is faster than many competitors in this price range. In our tests, it cut cleanly through normal grass and handled light weeds without bogging down. The automatic line feed advanced smoothly when needed.

At 6.3 pounds, it strikes a good balance between stability and maneuverability. You can work for extended periods without fatigue, but the tool still feels substantial in your hands.

Who Should Buy This

This is the best string trimmer for value-conscious buyers who want a complete package. The included spools and extra battery mean you will not need to make additional purchases for months.

Who Should Skip This

If you prefer buying from established brands with widespread service networks, MZK is still building its reputation. Also, the 12-inch cutting width means more walking for large properties.

7. BLACK+DECKER BESTE620 – Reliable Corded Performer

The BESTE620 is a workhorse corded trimmer that has earned its place in Black+Decker’s lineup. With over 1,000 reviews and a 4.4-star average, it has proven reliable for thousands of homeowners.

The EASYFEED system is similar to the automatic feed on other Black+Decker models. Push the button and the line extends. It works well when the line is fresh, though some users report feeding issues as the spool depletes.

At 7 pounds, it is slightly heavier than the BESTA510 but still manageable for most users. The extra weight comes from the more robust construction and larger motor housing. The tool feels solid in your hands.

The edger function works well for maintaining existing edges. You will not create perfect lines in overgrown areas, but for weekly maintenance it is adequate. The wheeled guide helps keep the cut straight.

Who Should Buy This

This is the best string trimmer for homeowners who want a reliable corded option from a trusted brand. If you have had good experiences with Black+Decker tools, this continues that tradition.

Who Should Skip This

If you are frustrated by line that breaks frequently or have a large property with limited outlets, look at cordless options instead. The cord limitation is real for some yard layouts.

8. BLACK+DECKER LST201 – Best Lightweight Cordless

The LST201 is the lightest cordless trimmer we tested at just 4.5 pounds. For users who struggle with heavier tools, this can be the difference between doing the yard work yourself and hiring help.

Do not let the light weight fool you. The 20V motor still delivers enough power for typical residential trimming. It is not a brush cutter, but for maintained lawns and light weeds, it gets the job done.

The battery runtime is the main limitation. Expect 12 to 15 minutes of continuous use on a full charge. For small yards, that is plenty. For larger properties, you will want a second battery or need to take a charging break.

The adjustable shaft is a nice touch at this price point. You can set the length for comfortable operation whether you are 5 feet or 6 feet tall. The 180-degree head rotation lets you switch between trimming and edging positions.

Who Should Buy This

This is the best string trimmer for users who prioritize light weight above all else. If you have physical limitations or simply want the easiest tool to handle, the LST201 delivers.

Who Should Skip This

Anyone with a medium to large yard should look at models with longer runtime. The 10-inch cutting width also means more walking to cover your property.

9. Greenworks 24V Cordless Trimmer – Best for Small Yards

Greenworks has built a reputation for affordable, reliable battery tools, and this 24V trimmer continues that tradition. It is a solid middle-ground option between budget 20V models and more powerful 40V+ systems.

The 90-degree rotating head is genuinely useful. You can angle the head to trim under fences, along retaining walls, or in other awkward spots that would be difficult with a fixed head. It is a feature I used more than I expected.

The quiet operation is another highlight. At 75 decibels, you can trim early in the morning without annoying the neighbors. Many HOAs have noise restrictions, and this trimmer complies with most ordinances.

If you already own other Greenworks 24V tools, this is an easy recommendation. The battery interchangeability means you can expand your tool collection without buying more batteries and chargers.

Who Should Buy This

This is the best string trimmer for homeowners already in the Greenworks ecosystem or those with small yards who want quiet, emission-free operation. The rotating head adds versatility for tricky landscaping.

Who Should Skip This

If you need to clear heavy weeds or have a large property, the 30 to 40 minute runtime will frustrate you. Also, if you prefer staying with one battery platform, check what other tools Greenworks offers before committing.

10. Husqvarna 122C – Best Entry-Level Gas Trimmer

Husqvarna is a legendary name in outdoor power equipment, and the 122C represents their entry-level gas trimmer. It brings professional pedigree to homeowners who need more power than electric can provide.

The 22cc engine spins at 10,000 RPM, significantly faster than most battery models. This translates to cleaner cuts and better performance in thick vegetation. If you regularly deal with overgrown areas, gas power still has advantages.

Smart Start Technology actually works. The engine is designed to start with minimal pulling effort. After the initial fuel priming, most users can start the trimmer in 2 to 3 pulls. It is not quite as easy as pushing a button, but it is as close as gas gets.

The curved shaft design reduces vibration transfer to your hands and arms. You can work longer without fatigue compared to straight-shaft models. The trade-off is reduced reach under obstacles.

Who Should Buy This

This is the best string trimmer for homeowners with large properties or heavy vegetation who are ready to embrace gas power. The Husqvarna quality and easy starting make it a good first gas trimmer.

Who Should Skip This

If you hate maintenance or live in an area with noise restrictions, stick with battery power. Gas trimmers require fuel mixing, seasonal maintenance, and acceptance of noise and fumes.

11. Husqvarna 130L – Best Professional Gas Trimmer

The Husqvarna 130L is a step up from the 122C, with more power and professional features. The 28cc engine and 18-inch cutting width make this a tool for serious yard work, not just weekend touch-ups.

The Rapid Replace head is worth the price premium alone. If you have ever spent 20 minutes trying to wind line onto a standard trimmer head, you will appreciate being able to reload in under 60 seconds. It is a genuine time-saver over a season of use.

The straight shaft extends your reach under bushes, fences, and other obstacles. It also accepts some attachments, though not as many as split-shaft designs. For pure trimming performance, the straight shaft is preferred by professionals.

LowVib Technology uses rubber mounts to isolate engine vibration from the handles. At 12.2 pounds, this trimmer is heavy, but the anti-vibration system makes it manageable for extended use.

Who Should Buy This

This is the best string trimmer for property owners with large areas to maintain or commercial users who need reliable gas power. The Rapid Replace head and easy starting justify the premium price.

Who Should Skip This

If you only trim a small yard weekly, this is overkill. The weight, maintenance requirements, and price make sense for heavy users but not casual trimmers.

12. Wild Badger Power 26cc – Best Multi-Function Tool

The Wild Badger Power trimmer is a Swiss Army knife of yard tools. It functions as a string trimmer, edger, and brush cutter, swapping between modes with attachment changes. For properties with varied terrain and vegetation types, this versatility is valuable.

The 26cc full-crank engine is built for durability. Full-crank designs distribute wear more evenly than half-crank engines, potentially extending the tool’s life. The 3-year warranty for both residential and commercial use shows the company stands behind the product.

The brush cutter blade transforms this from a grass trimmer into a tool that can handle saplings and thick brush up to 1 inch in diameter. If you are reclaiming overgrown property, this capability is essential.

The included shoulder strap helps manage the 12-pound weight when using the brush cutter attachment. With the strap properly adjusted, you can work for extended periods without excessive fatigue.

Who Should Buy This

This is the best string trimmer for property owners with varied needs. If you have grass to trim, edges to maintain, and brush to clear, the 3-in-1 design saves you from buying multiple tools.

Who Should Skip This

If you only need to trim grass around a manicured lawn, the extra complexity and weight are not worth it. Also, some users report overheating during extended use, so avoid this if you need to run the tool for hours at a time.

13. LawnMaster No-Pull Gas Trimmer – Best Innovation

The LawnMaster NPTGSP2617A solves the biggest pain point of gas trimmers: the pull start. With a push-button electric start powered by a small onboard battery, you get gas power with battery convenience.

The electric start battery provides up to 250 starts per charge. Since the engine runs on gas, you are not draining the electric battery during operation. It is a clever hybrid approach that works well when the system functions properly.

The anti-vibration handle rotates 360 degrees, letting you find the most comfortable grip angle. This is especially useful when trimming at different heights or working on slopes.

The 17-inch cutting width matches professional-grade trimmers, letting you clear large areas efficiently. The dual-line bump feed head extends line with a tap on the ground.

Who Should Buy This

This is the best string trimmer for users who want gas power but struggle with pull starts. If you have shoulder issues or simply hate yanking cords, the electric start is genuinely useful.

Who Should Skip This

The weight and reported reliability issues are concerning. If you need a tool that absolutely must work every time, stick with proven brands like Husqvarna or EGO until LawnMaster builds a longer track record.

14. CRAFTSMAN CMEST900 – Best Budget Corded

The CMEST900 is CRAFTSMAN’s entry-level corded trimmer, offering basic functionality at a budget price. It does not have the power of the CMEST913, but for light trimming tasks it is adequate.

The automatic feed spool extends line as needed without bumping. This feature works well initially, though some users report issues developing over time. For occasional use, it should hold up fine.

The turn-to-edge feature helps create clean borders along sidewalks and driveways. You rotate the head and use the built-in guide wheel to maintain a straight line. It is not perfect, but it is better than freehand edging.

At this price point, you are getting a functional trimmer without frills. It will handle grass trimming and light edging, but do not expect it to tackle overgrown weeds or thick brush.

Who Should Buy This

This is the best string trimmer for the absolute lowest budget. If you need something basic for a small yard and do not want to spend more than necessary, the CMEST900 gets the job done.

Who Should Skip This

If you have anything more than light grass to trim, spend a bit more for a more powerful model. The 12-inch width and modest motor limit this trimmer to small, well-maintained properties.

15. BLACK+DECKER ST4500 – Simple and Reliable

The ST4500 is a classic design that has been selling for years with good reason. It is simple, lightweight, and affordable. Sometimes you do not need the latest technology; you just need a tool that works.

The bump-feed spool is more reliable than automatic feed systems on budget trimmers. When you need more line, you tap the head on the ground while the motor is running. It is low-tech but effective.

At 4 pounds, this is the lightest trimmer in our entire roundup. If you have wrist issues or simply want the easiest tool to handle, the ST4500 is worth considering despite its basic feature set.

The 3.5-Amp motor is modest but sufficient for typical grass trimming. Do not expect it to power through thick weeds, but for weekly maintenance of a manicured lawn, it is adequate.

Who Should Buy This

This is the best string trimmer for users who prioritize simplicity and light weight over features. If you want a basic tool for occasional use at the lowest possible price, the ST4500 delivers.

Who Should Skip This

Anyone with heavy trimming needs or large properties should look elsewhere. The small motor and bump feed require more effort than modern automatic feed systems.

String Trimmer Buying Guide

Choosing the best string trimmer for your needs involves more than just picking the highest-rated model. Here is what you should consider before making a purchase.

Battery vs Gas vs Corded: Which Power Source is Right for You?

Battery-powered trimmers have come a long way in recent years. Modern lithium-ion batteries provide enough power for most residential use, and the convenience of no cord and no gas is hard to beat. The trade-off is runtime and upfront cost, especially if you need extra batteries.

Gas trimmers still reign supreme for heavy-duty work and large properties. If you need to clear thick brush or run your trimmer for hours at a time, gas is your best option. The downsides are maintenance, noise, fumes, and the hassle of dealing with fuel.

Corded electric trimmers offer the best power-to-price ratio. For under $60, you can get a trimmer that rivals $200 battery models in cutting performance. The obvious limitation is the cord, which restricts mobility and requires management.

Line Feed Systems Explained

Bump feed systems extend line when you tap the trimmer head on the ground while the motor is running. They are reliable and simple but require you to stop and bump the head when you need more line.

Automatic feed systems extend line when you release and re-squeeze the trigger, or continuously feed line as needed. When they work well, they are convenient. When they malfunction, they are frustrating. Higher-end trimmers generally have better auto-feed implementations.

Some premium models now offer push-button feed, letting you extend line with a button press while working. This is the most convenient system but adds cost and complexity.

Cutting Width Matters

The cutting width, measured in inches, determines how much grass you cut with each pass. A 15-inch trimmer covers 25% more ground per pass than a 12-inch model. For large properties, that time savings adds up.

However, wider cutting heads are heavier and less maneuverable in tight spaces. For intricate landscaping with lots of obstacles, a narrower 12-inch head might actually be faster overall.

Weight and Ergonomics

Even a few pounds make a significant difference during extended use. A 6-pound trimmer feels light at first but can cause fatigue after 30 minutes. A 12-pound gas trimmer requires breaks and possibly a shoulder strap.

Look for adjustable shaft lengths, rotating handles, and anti-vibration features. These details determine whether trimming is a quick chore or an exhausting ordeal.

Battery Ecosystem Strategy

This is the advice I give everyone buying their first battery trimmer: think about the ecosystem. Brands like EGO, Ryobi, Milwaukee, and Greenworks offer dozens of tools that share batteries. Once you invest in one platform, staying within that brand saves money.

Before buying, check what other tools you might want in the future. If you need a leaf blower, hedge trimmer, or chainsaw, buying into a comprehensive ecosystem is smarter than mixing brands.

Frequently Asked Questions

Final Thoughts

After testing 15 of the best string trimmers available in 2026, our recommendation is clear: the EGO POWER+ ST1502SA offers the best combination of power, convenience, and value for most homeowners. Its 56V battery system delivers gas-like performance without the maintenance, and the Rapid Reload head makes line changes effortless.

For budget buyers, the BLACK+DECKER BESTA510 proves that corded trimmers still have a place. At under $50, it delivers performance that rivals battery models costing four times as much.

If you are just starting your battery tool collection, think carefully about which ecosystem to join. EGO, Ryobi, Greenworks, and others all offer comprehensive tool lineups that share batteries. Choose the platform that has the other tools you will need in the future.

Whatever you choose, the best string trimmer is the one that gets used. A perfect lawn does not require the most expensive tool, just one that fits your needs and gets the job done.
