Let’s be real; nobody wants a yard that looks like a jungle. If your lawnmower can’t reach those tricky corners or your current whacker is just whacking out, it is time for an upgrade.

Electric vs. Gas vs. Battery Powered
Before you buy, you need to pick your power source. You generally have three flavors: corded electric, gas-powered, and battery-powered string trimmers. Each handles the job differently.
Electric (Corded)
Pros
- Unlimited runtime: As long as you have power, you can keep cutting.
- Eco-friendly: No fumes or emissions.
- Lightweight: No heavy battery or gas tank to lug around.
- Cost-effective: These are usually the cheapest options.
Cons
- Tethered range: You can only go as far as your extension cord allows.
- Cord management: It is easy to trip over or accidentally cut the cord.
Gas
Pros
- Raw power: Tears through thick brush and tall weeds easily.
- Go anywhere: No cords or charging times to worry about.
- Durable: Built to handle tough, all-day jobs.
Cons
- Maintenance heavy: Requires mixing fuel, oil changes, and engine care.
- Loud and heavy: You will likely need ear protection, and they can tire out your arms.
- Emissions: They produce exhaust fumes.
Battery Powered
Pros
- Grab and go: Instant start with the push of a button.
- Quiet operation: Your neighbors will appreciate the lower noise levels.
- Low maintenance: No gas, oil, or spark plugs to change.
- Improving power: Modern high-voltage batteries rival gas performance.
Cons
- Runtime limits: You are done when the battery dies unless you have a spare.
- Cost: Batteries and chargers can be expensive to replace.
The right choice comes down to your property size. Small yards do great with electric, while large acreages still benefit from gas.
Factors to Keep in Mind
Beyond the power source, here is what you should look for to get the best cut.
Performance and Cutting Power
For gas trimmers, look at the engine displacement (cc). A 25cc engine is standard for homeowners, while anything over 30cc is professional-grade.
For battery models, look at the voltage. A 20V trimmer is fine for light edging, but for thick grass, you want at least 40V or 60V.
Also, check the cutting swath (width). A 10 to 12-inch swath is fine for small patios, but a 14 to 16-inch swath helps you clear large areas much faster.
Versatility and Attachments
Some trimmers are “attachment capable,” meaning you can swap the head for a blower, edger, or hedge trimmer. This splits the cost of the engine across multiple tools. If you just need to edge the driveway, look for a trimmer with a rotating head and a guide wheel.
Shaft Style
You will see curved and straight shafts. Curved shafts are generally lighter and easier to maneuver around flower beds, making them great for shorter users. Straight shafts provide a longer reach, better balance, and are easier to use under fences or decks.
Weight and Balance
A 12-pound gas trimmer might not feel heavy in the store, but it will feel like a ton after 20 minutes of work. Battery and corded units are usually lighter (5 to 10 pounds). Look for a unit that feels balanced when you hold it by the handle, so the head does not constantly dip toward the ground.
Feed System
The “bump feed” is the standard; you tap the head on the ground to release more line. It is reliable but requires practice. “Automatic feed” releases line as needed without you doing anything, which is great for beginners but can use up string faster.
Budget
Corded electric models are the wallet-friendly winners, often dipping under $50. Good battery models usually range from $100 to $250 depending on if the battery is included. Gas models start around $150 but can easily exceed $300 for commercial quality.
Product Reviews
I’ve analyzed the top contenders to see which ones slice through weeds and which ones just tangle up. My review process looks at cutting power, battery life, weight balance, and how easy it is to reload that annoying spool.
Here are the string trimmers that made the cut.
Dewalt 20V MAX String Trimmer
Best Cordless String Trimmer
The Dewalt 20V MAX is a standout because it solves the biggest storage problem: length. This tool features a specialized hinge that allows you to fold the shaft in half. You can easily toss it in the trunk of a sedan or hang it on a compact wall rack in the garage.
It isn’t just a gimmick, though. It runs on Dewalt’s reliable 20V battery platform, so if you already own their drills or saws, you are good to go. It offers a 14-inch cutting swath, which bridges the gap between residential and pro-grade tools.
What We Like
QuickLoad Spool
Rewinding string is usually a nightmare, but the QuickLoad spool changes that. You don’t have to take the head apart; just insert the line and twist to wind it up. It saves serious time and frustration.
Variable Speed Trigger
You get a Hi/Lo speed switch plus a variable trigger. This gives you total control. Use “Lo” for trimming easily along flower beds to save battery, and kick it into “Hi” to slash through thick weeds.
Compact Storage
The folding shaft reduces the tool’s length by 40 percent. If you have a small shed or transport your tools between properties, this feature is unbeatable.
Durable Brushless Motor
The brushless motor is efficient and durable. It extends run time and lifespan compared to older brushed motors, handling thick grass without bogging down immediately.
What We Don't Like
Guard Size
The debris guard is on the smaller side. While this helps with visibility, you might get legs covered in grass clippings if you wear shorts.
Battery Sold Separately (Sometimes)
Be careful when ordering. Some listings are “tool only,” meaning you need to buy the battery and charger separately. If you don’t already own Dewalt tools, this increases the upfront cost.

Black + Decker 20V Max String Trimmer
Most Versatile
The Black + Decker LSTE525 is designed for the suburban homeowner who wants a perfectly manicured look without the hassle. It is a true 2-in-1 tool that converts from a trimmer to a wheeled edger in seconds.
It is part of the 20V MAX system, which is great for light to medium yard work. The Power Drive Transmission gives it plenty of torque to keep the string spinning even when cutting through denser patches of grass.
What We Like
Wheeled Edging
This is the standout feature. The head rotates, and a small wheel supports the weight of the tool. You can walk along your driveway or sidewalk for a crisp, professional edge without having to hold the trimmer in an awkward position.
EASYFEED Button
Forget bumping the head on the ground. This unit has a button near the handle that advances the line when you push it. You can get a fresh line without stopping your work.
Adjustable Height
The telescopic pole adjusts to your height, and the handle is adjustable, too. This helps prevent back strain, whether you are tall or short.
Two-Speed Control
Switch between power and runtime. Use the lower setting for standard grass to squeeze more life out of the battery, or crank it up for the tough spots.
What We Don't Like
Not For Overgrowth
This is a maintenance tool, not a brush cutter. If you try to clear a field of tall, thick weeds, the motor will struggle, and the battery will drain very fast.
Single String Line
It uses a single 0.065-inch line rather than a dual line. While this is easier to manage, it cuts slightly slower than dual-line models.

Black + Decker BESTA510 String Trimmer
Best Lightweight String Trimmer
If you don’t want to worry about charging batteries or mixing gas, the Black + Decker BESTA510 is a reliable plug-and-play option. It boasts a 6.5-amp motor, which is surprisingly punchy for its size.
Weighing in at barely over 6 pounds, it is incredibly easy to maneuver. This makes it an excellent choice for anyone who finds gas trimmers too heavy or intimidating to operate.
What We Like
Unlimited Power
Because it is corded, you never experience power fade. It runs at 100 percent efficiency from the moment you start until you finish the job.
14-Inch Cut Width
Despite being compact, it has a 14-inch cutting width. This lets you clear more grass in a single pass compared to smaller 10 or 12-inch electric models.
Cord Retention Hook
A common annoyance with corded tools is the plug popping out. This unit has a built-in retention hook that secures your extension cord, so you don’t accidentally unplug it while moving around the yard.
2-in-1 Edging
Like its battery-powered cousin, this model transforms into an edger with a guide wheel. It makes cleaning up sidewalks easy and precise.
What We Don't Like
Tethered to the House
You are limited by the length of your extension cord. This is strictly for small to medium yards where an outlet is always within reach.
Auto-Feed Can Be Sensitive
The automatic feed spool (AFS) works well, but some users find it feeds too much line, wasting string. You might go through spools faster than expected.

Ryobi ONE+ Battery String Trimmer
Best Electric String Trimmer
Ryobi is a household name for a reason. The ONE+ system is massive, meaning the battery from this trimmer works with over 250 other tools. This particular kit is a great value because it often comes bundled with a blower, solving two lawn care problems at once.
This unit focuses on user comfort and flexibility. It is lightweight, adjustable, and perfect for the average suburban lot where noise and emissions are a concern.
What We Like
Rotating Shaft for Edging
The shaft rotates 180 degrees to turn the trimmer into an edger. It is simple to use and allows you to kick the head vertical to clean up walkway borders.
Adjustable Cut Width
You can toggle the cutting width between 11 and 13 inches. Keep it at 11 inches to maximize battery runtime, or widen it to 13 inches to cut faster in open areas.
Compatible Battery System
The 18V ONE+ battery is the star here. If you run out of juice, you can grab the battery from your Ryobi drill or leaf blower and keep working.
Auto-Feed Line
No bumping required. Every time you release the trigger, the auto-feed system advances the line about 1/4 inch, keeping your cutting string at the optimal length.
What We Don't Like
Single Line Cutting
It uses a single 0.080-inch line. While 0.080 is a decent thickness, a single line is generally less efficient at clearing thick patches than dual-line heads.
Plastic Build
To keep the weight and cost down, there is a lot of plastic in the construction. It is durable enough for normal use, but it won’t take a beating like a steel-shaft gas trimmer.

Honda 35 cc Straight Shaft Trimmer
Most Powerful
The key difference here is the “4-stroke” part. Unlike most gas trimmers, you do not need to mix gas and oil. You just put straight gas in the tank and check the oil separately, just like a car. It runs cleaner, quieter, and starts easier than 2-stroke rivals.
What We Like
No Fuel Mixing
The hassle of measuring ratios and mixing oil into gasoline is gone. This is a huge convenience factor and prevents engine damage caused by improper fuel mixes.
Incredible Torque
The GX35 engine is legendary for a reason. It produces consistent torque even at partial throttle. It won’t stall out when you hit a patch of dense thistle or tall grass.
Low Vibration
Honda engineered the shaft and engine mounts to absorb shock. This means less tingling in your hands after a long session of trimming.
Commercial Durability
This is built for heavy duty work. From the deflector shield to the trigger assembly, everything feels solid and ready for abuse.
What We Don't Like
It Is Heavy
Power comes at a price. This unit is significantly heavier than battery models. While it comes with a harness, you will definitely feel the workout in your shoulders.
Head Restringing
The stock trimmer head can be a bit fiddly to reload compared to modern speed-load heads. Many pros swap the stock head for an aftermarket “Speed-Feed” head for easier loading.

EGO Power+ Foldable String Trimmer
Best Quiet String Trimmer
EGO has revolutionized the lawn industry by proving battery power can match gas performance. This EGO Power+ model utilizes a 56V ARC Lithium battery that provides gas-like power without the noise, fuss, or fumes.
It is one of the quietest trimmers available, making it perfect for early morning work. Plus, EGO’s “Powerload” technology solves the biggest headache in lawn care: winding the string.
What We Like
Powerload Technology
This is a game-changer. To reload the line, you feed it through the head and press a button. The trimmer automatically winds the line for you in seconds. No twisting, no disassembling.
Carbon Fiber Shaft
Instead of aluminum, this model uses a carbon fiber shaft. It is incredibly strong but much lighter, and it carries a lifetime warranty on the shaft itself.
Variable Speed
You can feather the trigger for delicate trimming around flowers or squeeze it fully to blast through overgrown weeds. The response is instant.
Split Shaft Design
Like the Dewalt, this shaft folds or splits (depending on the specific sub-model in the kit), making it easy to stash in a car trunk or a crowded garage.
What We Don't Like
Battery Cost
If you buy the tool-only version, be aware that EGO batteries are expensive. However, they are high quality and work across EGO’s lawn mowers and blowers.
Rear Heavy
Because the battery is large (to provide that 56V power), the tool can feel a bit rear-heavy. Using a shoulder strap helps balance it out significantly.

Greenworks 15-Inch Corded String Trimmer
Best Affordable String Trimmer
You don’t need to spend hundreds of dollars to keep a tidy lawn. The Greenworks 15-Inch Corded Trimmer is the budget king. It delivers a solid 5.5 amps of power, which is plenty for standard grass and weeds.
It is simple, lightweight, and effective. If you have a small yard and an extension cord, this offers the best bang for your buck on the market.
What We Like
Dual Line Cutting
Unlike many cheap trimmers that use a single string, this uses a dual-line head. This doubles the cutting action per rotation, giving you a cleaner cut faster.
Price Point
It is hard to beat the value here. It costs a fraction of what gas or high-voltage battery trimmers cost, yet it still gets the job done reliably.
Edging Capability
The head rotates 90 degrees for edging. It includes a metal wire guide to help keep you from scalping the lawn or hitting the pavement while you edge.
Start Instantly
There is no priming, choking, or charging. Plug it in, squeeze the trigger, and you are working. It is the definition of hassle-free.
What We Don't Like
Manual Line Advance
While it claims auto-feed, many users find it works better if you manually manage the line or replace the head with a better aftermarket one eventually.
Cord Lock Is Essential
You must use the built-in cord lock hook. If you don’t, the heavy extension cord will pull the plug out constantly, which gets annoying very quickly.

Safety Tips for Using a String Trimmer
These tools spin at thousands of RPMs. Keep these tips in mind to keep your toes (and windows) safe:
- Wear the gear: Safety glasses are non-negotiable; a rock flying at 100mph can cause serious damage. Long pants protect your shins from flying debris and poison ivy.
- Mind the spin direction: Most trimmers spin counter-clockwise. This means they eject debris to the left. Try to work so the debris flies away from your body and away from windows or parked cars.
- Check the ground: Before you start, do a quick walk-around. Pick up dog toys, large rocks, wire, or hoses. If a trimmer line hits a hose, it will slice it instantly.
- Don’t cut in the rain: Wet grass clogs the trimmer head and makes the ground slippery. It is harder on the engine and leaves a ragged cut on your lawn.
- Watch the gap: When trimming near chain-link fences, don’t push the string into the fence. It will eat your line immediately. Ease up to it gently.
- The right grip: Keep a firm grip with both hands. Do not operate the trimmer one-handed, even if it is lightweight.
FAQs About String Trimmers
What Size String Trimmer Do I Need?
If you have a standard suburban yard (under 1/4 acre), a 13-inch battery or corded trimmer is perfect. For properties over 1/2 acre or areas with thick, woody weeds, look for a gas or high-voltage (60V+) battery trimmer with a 15-inch or larger cutting swath.
Can I Use a Thicker Trimmer Line?
Only if your manual says so. Most light trimmers use 0.065-inch line. Medium-duty units use 0.080-inch, and gas units often use 0.095-inch or thicker. Forcing a thick line into a small motor creates drag and can burn out the engine.
Are Trimmer Heads Universal?
Not all of them. While many “universal” heads exist, the bolt sizes and thread rotation (left-hand vs. right-hand thread) vary by brand. Always check the compatibility list on the packaging before buying a replacement head.
What Trimmer Do Landscapers Use?
Pros almost exclusively use gas-powered straight-shaft trimmers from brands like Stihl, Echo, or Husqvarna. However, many commercial crews are slowly transitioning to high-end battery systems to reduce noise complaints in residential areas.
Are Curved or Straight Trimmers Better?
Straight trimmers are generally better for ergonomics and reach. They allow you to trim under bushes and decks easily. Curved trimmers are often lighter and easier to control for shorter users but lack the reach and torque of straight-shaft models.
Are Plastic Blades on a Strimmer Any Good?
Plastic blades are great for thick, leafy weeds that a string can’t cut. However, they are brittle. If you hit a concrete curb or a rock, the blade will snap instantly. Use string for edging and blades for open-field clearing.
How Do I Maintain My String Trimmer?
For electric models, simply keep the air vents clean and store them in a dry place. For gas models, change the air filter annually, check the spark plug, and use fresh fuel. If storing a gas trimmer for winter, drain the fuel tank to prevent the carburetor from clogging.
String Trimmer vs. Brush Cutter: What’s the Difference?
A string trimmer uses a nylon line to cut grass and light weeds. A brush cutter uses a metal blade to saw through saplings and dense brush. Some powerful trimmers allow you to swap the string head for a brush cutter blade, but lower-power electric models cannot handle the resistance.
