Best Overall: Husqvarna 128LD 28 cc 17” String Trimmer

A high-performance model from a trusted brand, the Husqvarna 128LD is the gold standard of string trimmers.

Here are the features we liked the most:

  • 28 cc, two-cycle engine provides plenty of cutting power without weighing a ton.
  • “SmartStart” recoil system, which reduces starting cord resistance by 40%.
  • Simple stop/return switch quickly cuts power to the string head.
  • A translucent fuel tank lets you know how much juice you have left.
  • Several attachments available, including a wheeled edger, pole saw, and tiller.

This gas string trimmer is one of the more expensive options on our list, but this durable Husqvarna trimmer is a great investment and will stand up to years of heavy use.

Note: Because this string trimmer has a 2-stroke engine, it requires special oil to be mixed with gasoline, which is included with purchase.

Pros Cons
✓ Easy start✓ Best-in-class engine power✓ Wide cutting swath for efficiency ✗ Pricey✗ Attachments are expensive

Best Curved Shaft: Husqvarna 128CD Curved-Shaft Trimmer

With the same engine and features of our top-pick gas string trimmer, the Husqvarna 128CD is the clear choice for a curved-shaft model.

What is the advantage of a curved shaft string trimmer? A curved shaft is more ergonomically effective than a straight one. With better weight distribution, it’s easier to hold close to the ground while you remain upright.

Like its straight-shafted twin, the 128CD features a 28 cc engine and Husqvarna’s “SmartStart” system. The translucent fuel tank lets you keep an eye on your fuel, and the quick stopping switch helps keep you safe.

At 11 pounds, this is a lighter option gas string trimmer that puts ease-of-use first. The only downside of using a curved shaft string trimmer is that it can be harder to get in tight spots and underneath fences.

Bonus Points: This Craftsman gas string trimmer is compatible with a full line of Craftsman TrimmerPlus accessories for even more versatility.

Downside: The nut that changes the cutting head of this string trimmer can be awkward, as it’s bolted on with reverse threads. Many customer reviews note this as a failing, as the reverse thread is not clearly marked.

Buyers Guide: Gas String Trimmers

Gas string trimmers are the industry standard for lawn care professionals and residential operators alike. Gas engines are reliable and can quickly be refueled in the field. Though they require considerably more maintenance than electric string trimmers, they’re the better option for dealing with thicker weeds and brush.

Even with advancements in battery technology, the best electric string trimmers can’t beat the cutting power and longevity of gas string trimmers.

This buyers guide will outline the key specs to look for when purchasing a gas trimmer, and help you make an informed decision.

What to Look for in a Gas String Trimmer

The most important factors to consider when buying a gasoline-powered string trimmer are:

We’ll take a look at each of these factors to give you a better idea of the range of products on the market and choose the trimmer that best fits your needs and budget.

Engine Power

Because horsepower is a variable measurement, the easiest stat to look at when determining an engine’s consistent output is its capacity. Measured in cubic centimeters (cc), this lets you know how much fuel is burning with each stroke of the motor. A higher capacity means more power in each stroke and more torque.

High-powered engines will enable the cutting of thicker brush. If you’re planning to use your trimmer on regular lawn grass, you can save money and strain by going for a lighter, lower-power option. However, if you have wooded areas or wild growth on your property you may need to invest in a powerful brush cutter.


Different trimmers have different capabilities. Most of them come with the option to add certain attachments, such as a cutting blade or edging wheel. Knowing what tasks you’d like to accomplish before you purchase will ensure you buy the correct tool for your lawn.

The cutting width of a trimmer will also determine its utility and efficiency. A wider swath will enable you to cut more with each pass, saving you time and effort.

best, string, trimmers, 2023, reviews, brand


An important factor for any handheld tool, a trimmer’s weight will partially determine the length of time it can be used. Even professionals get tired lugging a 20-pound weed wacker around all day. Consider your limits and purchase something that will be comfortable to use.

If you need to purchase a heavier tool for the added power, shoulder straps are available that take the load off your arms, allowing comfortable regular use.


Residential gas weed wackers generally cost between 70 and 200, with high-end and commercial models costing as much as 400. The wide price range makes it easy to find something that fits your budget.

FAQ About Gas-Powered String Trimmers

Our head-to-head reviews show that the Husqvarna 128LD (or CD, depending on shaft preference) is the most reliable trimmer on the market.

Electric trimmers have come a long way in the last two decades. Modern battery-powered trimmers, especially ones with a high-voltage battery, can deliver comparable power to gas, without the emissions and maintenance that come with burning fossil fuels.

Gas engines still have the upper hand when it comes to heavy-duty work. Very few electric trimmers can handle saplings or wooded brush, so your needs will depend on the type of foliage you plan to cut.

Additionally, some areas of the U.S. are encouraging or requiring more power tools to be powered by electricity, so it’s a good idea to check your local and state regulations before committing to gas.

Most professionals and enthusiasts use straight-shafted trimmers, as the shape makes it easier to trim in hard-to-reach places. Taller people, especially over 6 feet, often say a straight shaft is more comfortable as well.

For most people, a curved shaft will distribute the trimmer’s weight more ergonomically, putting less strain on the back and shoulders.

Gas weed eaters are sold at a wide range of prices. With less expensive models costing under 100 and higher-end models going for as much as 350 or more, your budget is an important consideration. With fuel, oil, and accessories adding costs, plan to spend around 200 for a well-made, effective trimmer.

Gas Weed Eater Won’t Start: Causes and Steps to Troubleshoot

Gas weed eaters offer lots of power – unless they won’t start, that is. It can be so frustrating when a string trimmer won’t crank and the truth is, there could be a lot of reasons why. But there are a few simple checks that you should make before taking it to a professional or tossing it in the trash.

If your gas weed eater is not starting, the most common causes are:

Depending on what is preventing your weed eater from working correctly, troubleshooting is a fairly simple process.

Gas Weed Eater’s Common Issues And Solutions

Often after being stored over winter or just by luck of the draw, a gas-powered weed eater will need a little maintenance to work correctly again. But when you get right down to it, they have a simple two-stroke engine that you can troubleshoot with basic tools and a little DIY knowledge.

Fuel Related Issues

Fuel related issues are the most common problems you will need to solve over the life of your weed eater. Here are a few of the more common fuel issues that may be causing a problem:

  • The fuel is running low
  • The tank is full, but with old fuel. Oxygen and moisture can damage the fuel over time.
  • The gasoline and oil have separated, preventing the engine from getting enough fuel.

Troubleshooting Fuel Related Issues

To solve fuel-related problems, proceed with these steps:

  • First, check the level of fuel in the tank. If it is empty or low, the weed eater will not start.
  • If there is enough fuel and it is fresh, lightly shake and swirl the weed eater to ensure that oil and gasoline are not separated.
  • If you are using the weed eater for the first time after several months, you should swap the old fuel for a new mixture. Many string trimmers require a 40:1 or 50:1 gas-to-oil ratio. (Check your owner’s manual for your model’s requirement).
  • It is extremely important that you use gasoline with only 10% alcohol or an ethanol-free variety and oil designed for 2-cycle engines. This allows for the piston and crankshaft to stay lubricated.

Spark Plug Issues

If you have tried to turn the engine on and it is not giving you any sign of life, the problem might lie in the spark plug.

A fouled spark plug won’t be able to deliver electric current from the ignition system, which is necessary to ignite the fuel in the combustion chamber of your weed eater. In this case, the possible issues are:

Troubleshooting Spark Plug Related Issues

If the problem involves a dirty spark plug, you can quickly solve it by cleaning it with a spray-on plug cleaner (source).

To remove any extra debris, proceed by scraping the spark plug with a knife. For the best maintenance, you should clean the spark plug every season and after prolonged use (around 25 hours).

If the spark plug is cracked or faulty, you will need to replace it altogether. These are inexpensive and easy to buy in your local DIY store. To check for a damaged spark plug, you should:

  • Disconnect the lead and clean the surrounding area
  • Remove it using a spark plug socket
  • Check the porcelain for cracks and scratches

Assuming it isn’t cracked, it probably just needs a good cleaning. Once cleaned, replace the spark plug, ensuring that it is not too tight and try to restart the engine.

Carburetor Issues

The carburetor is the heart of the engine. It is responsible for controlling the engine’s speed and the ratio between fuel and air.

If your carburetor is amiss, dirty, or cracked, your weed eater won’t work. Some common telltale signs of a fault carburetor are:

Troubleshooting Carburetor Related Issues

The first thing we want to do is to clean the carburetor. It’s a fairly easy task and doesn’t require a lot of tools.

Depending on your weed eater model, start by removing the filter cover and the filter. Then proceed by unscrewing the screws that hold the primer bubble in place. Once you have opened your carburetor, you can clean it thoroughly and unclog the filter.

You may be able to clean the carburetor without needing fresh gaskets but as a rule, it’s best to have an inexpensive rebuild kit like this one (link to Amazon) handy. If this one doesn’t match your weed eater’s engine, just search for your brand.

This YouTube video from eReplacement Parts walks you through the process of cleaning the carburetor and has a lot of handy tips.

Gas Weed Eater Won’t Start? Try This

Weed eater, weed whacker, string trimmer – no matter what you call it, here’s how to get it running again.

Shop the article

No matter what you call it – weed eater, weed whacker, string trimmer – chances are at some point it won’t start. Few things are more annoying than destroying your shoulder trying to start a gas weed eater when there’s work to do.

Fortunately, gas weed-eater engines are pretty simple, so most DIYers with a few tools and some basic know-how can troubleshoot a stubborn trimmer and get it running.

) Check The Gasoline

Gasoline can break down in as little as 30 days, especially today’s ethanol-containing gas.

Homeowners sometimes stash their string trimmer in the garage at season’s end without stabilizing the gas. Oxygen has all winter to break down and ruin the gasoline, leaving you with a trimmer that won’t start in the spring.

If your trimmer falls into this category, empty the old gas from the fuel tank and replace it with fresh fuel.

If your weed eater won’t start, trying removing the air filter and spraying carburetor cleaner into the intake.

) Clean The Carburetor

Once gas breaks down, varnish, gums and other debris can form inside the carburetor and clog the tiny fuel passages. This prevents fuel from reaching the combustion chamber and igniting, leaving you to struggle with a trimmer that won’t start.

Remove the air filter and spray carburetor cleaner into the intake. Let it sit for several minutes to help loosen and dissolve varnish. Replace the filter and try starting the trimmer.

If this doesn’t solve the problem, consider disassembling the carburetor to give it a more thorough cleaning.

Beware, however – taking apart a carburetor marks a point-of-no-return, of sorts. Understanding how the delicate gaskets, tiny screws and needle valves go back together can be a challenge, even on a relatively simple string-trimmer carburetor. Take pictures with your phone throughout the process to help reassembly. Clean all the openings and passages with carburetor cleaner.

If you’re reluctant to take apart the carb, visit the servicing dealer.

Remove the spark plug and use light sandpaper to clean electrode deposits to help fix a gas trimmer that won’t start.

) Clean/Replace Spark Plug

Oil deposits and carbon can foul the spark plug in a two-stroke engine if a low-quality oil is used. Deposits on the electrode prevent the plug from firing properly, which can reduce performance or prevent the engine from running altogether.

Plugs are inexpensive, so replace it if it’s fouled. If you don’t have a new plug available, clean the deposits from the electrode with light-duty sandpaper and check the gap. Consult the owner’s manual for the correct gap size.

If you know the spark plug is good, but the engine still doesn’t produce spark, the coil is likely to blame and requires replacement.

Direct compressed air from the inside of the air filter toward the outside to remove debris that may be restricting airflow.

) Clean/Replace Air Filter

A clogged air filter prevents the engine from receiving sufficient air to operate properly.

Before removing the air filter, brush away loose debris from around the filter cover and filter element. Tap rigid filters on a tabletop or the palm of your hand to dislodge any dirt or debris. Compressed air also works well. Make sure you direct air through the filter from the inside to avoid lodging debris deeper in the filter.

Avoid washing paper filters as this can collapse their micro-fine structure. Foam filters, however, can easily be washed using mild detergent and warm water.

As with the spark plug, however, replacement is often the best practice, especially if the filter is excessively dirty.

A spark-arrestor screen clogged with deposits can choke off airflow enough to prevent the trimmer from starting.

) Clean The Spark-Arrestor Screen

On many trimmers, a small screen covers the exhaust outlet and prevents sparks from exiting the muffler and potentially starting a fire.

As with plug fouling, too much oil in the gasoline, inferior oil and continued low-rpm operation can plug the screen with carbon deposits. This prevents exhaust-gas flow, which leads to power loss. In extreme cases, heavy deposits choke airflow enough to leave you with a weed eater that won’t start.

To fix the problem, remove the spark-arrestor screen and spray it with a heavy-duty cleaner, like AMSOIL Power Foam to soften the deposits before cleaning the screen with an abrasive pad. Reinstall the screen and test the trimmer.

Replace the screen altogether if it’s excessively plugged with carbon.

What Does Oil Viscosity Mean

Oil viscosity is the measure of its resistance to flow. How quickly or slowly motor oil flows affects how well it protects your engine.

The Best Weed-Eater String That Gets the Job Done Faster—2023 Buyer’s Guide

Weed-eater string for your weed whacker or trimmer may seem like a small thing to buy, but having the right string for the job can help you get more work done with less effort. String shape, material, durability, welding resistance, and line size are all important things to consider, and this updated buyer’s guide will help you choose the best weed-eater string for the task at hand.

It may seem like a small thing, but what kind of string you use in your weed eater (also called a weed whacker or string trimmer) can have a big impact on your gardening.

Heading out to your yard to maintain it should be an enjoyable—or at least hassle-free—experience. But we all know that using the wrong products can make yard upkeep a very frustrating experience.

And if you’ve ever been trimming your weeds only for the string to break or stick inside the spool, you know what I mean.

When this happens, you have to keep stopping to reload the string, which not only makes the job more time-consuming, it can lead to a rough and uneven cut.

The right kind of trimmer string is long-lasting and not easily breakable. It should provide clean and easy cuts, be able to handle thicker weeds and grass, and be quick and easy to reload when needed.

If you’ve recently purchased a new string trimmer (or if you’re in the market for one, here’s my guide to the best cordless trimmers and weed eaters), it likely came with a spool of string to start you off. But these strings aren’t always the best for the job, so it’s worth knowing what else is out there when it comes time to replacing them or buying more.

Below, you’ll find some of the best weed-eater strings available, as well as a buyer’s guide with key features to look out for.

Buyer’s guide

Now that we’ve taken a look at some of the best strings on the market, here are a few important factors to consider when buying the best string for your trimmer.

I’ll take you through some key decisions to make as far as finding the right shape, material, durability, weld resistance, and line size. This last factor is crucial, and you should always take a look at your trimmer’s manual or check out the manufacturer’s website to find out what string sizes will fit your machine.


Trimmer string comes in round, multi-sided, and twisted shapes. The performance is affected by the shape in many ways.

The cleanness of the cut, the durability of the string, and the noise level are all affected by the shape of the string. Different shapes are suited for different jobs so it’s important to find a shape that will match the job you use it for.

Let’s start with a round string. It comes in all sizes and is durable, economical, and easy to reload. If you’re using your trimmer on grassy lawns with minimal weeds, then a round string is the best choice.

Since it tears through weeds rather than cuts cleanly, a round-shaped string is not recommended for particularly weedy areas. A round string is also more likely to overheat and weld together when trimming along fences and concrete walls.

Twisted string is more suitable for thick weeds, as it has a cleaner cut and is more durable around hard surfaces. It’s also quieter and less likely to vibrate than other string shapes due to its reduced air resistance. For the quietest experience, use a twisted string in an electric or cordless trimmer.

If you’re using your trimmer on yards with thick grass and heavy weeds, then a multi-sided string is the best choice. Its sharp edges cut through weeds for a cleaner look. However, if there are a lot of obstacles or objects to maneuver around, then a multi-sided string may not be the best choice as it breaks quite easily along hard surfaces.


Basic trimmer string is made of hardened monofilament nylon, and this has been the industry standard for years. However, manufacturers are developing these products and making constant improvements to increase their capability and durability. So while plain nylon line is still effective, there are stronger materials out there.

For example, reinforced composite nylon is more resistant to breakage. Meanwhile, some products include materials like aluminum that are impregnated into the nylon to make it stronger.

Some trimmer strings are made from non-nylon polymers or copolymers as they are more durable, while some are made with hardened core material to reduce breakage.

But while all these options improve the durability of light gauge nylon string, if you’re mainly using your trimmer for light grass trimming, then a simple nylon line will do the job.


The test for durability comes with consistent use among heavy weeds and hard surfaces. A more durable string lets you do more work per spool, and the durability of the string varies on what material it’s made of, the shape of the string, what’s being trimmed, and friction with surfaces like stone or concrete. But the thicker the string is, the more durable it will be.

Round string tends to be the most durable. This is because it contains more material with less surface area and has a longer wear time. Round string that is made of reinforced nylon or non-nylon polymer, or a string with hardened core material, will be more durable than basic nylon.

Welding resistance

Welding occurs when the trimmer string gets too hot and sticks together on the spool. This happens when the trimmer is being operated at high speed while cutting along a resistant surface, such as a fence or a concrete sidewalk, for an extended period of time.

The added friction causes heat to build up, which softens the string and eventually causes it to stick together. To solve this problem, you will have to remove the spool and restring it.

Materials used to make trimmer strings are usually weld resistant, but some types of strings are more resistant than others. A shaped line is more weld-resistant than round because of the larger surface area. Round string has a smaller surface area which makes it overheat at a quicker rate.

Line Size

Another good indicator of durability is line diameter. Thicker lines last longer but also cost more. When deciding on the right line thickness for you, make sure to take cost, how often you want to reload, and your yard conditions into account. As previously mentioned, not all sizes fit all trimmers, so make sure to consult your trimmer’s manual before purchasing string for your trimmer.

For small to medium yards with few weeds, a light-duty weed-eater string with a diameter of.065 to.085 inch is suitable.

Meanwhile, a medium-duty trimmer string of.085 to.110 inch is recommended for larger yards with thick grass and more weeds.

For even larger properties that have heavy weeds, woody plants, and lots of fence lines and hard surfaces to trim along, a heavy-duty string greater than.110 inch in diameter is recommended.

Frequently asked questions

How do I install a new weed-eater string?

Some string trimmers require pre-cut lengths of line, while others use either one or two long lengths of line that wind onto a spool. This may require you to remove the spool from its housing, or you may need to load it in place.

For more information on your specific trimmer brand and model, consult your trimmer’s manual or the manufacturer’s website.

Which way should I wind the weed-eater string?

You should wind the string in the opposite direction of its rotation. This is usually counterclockwise. You may be able to find an arrow on the spool that shows the proper direction to wind the string.

How often do I have to replace weed-eater string?

You should only ever need to replace the string when it runs out unless it’s not feeding properly. String that is old or has been exposed to the elements over time can become brittle and may need to be replaced as well.

How does weed-eater string work?

A string trimmer usually uses a monofilament to cut through grass, weeds, and small, woody plants. A cutting head spins at a high speed and generates enough centrifugal force to hold the line at a stiff, horizontal angle. This is what makes the cutting possible.

You can manually adjust the height and arc of the string trimmer for cutting around trees, walls, and rock beds. Trimmers can also be turned vertically to edge out lines near sidewalks and driveways.

On many trimmers, the cutting heads and lines can be switched out to accommodate a variety of line gauges. It’s recommended to check what gauges your cutting head can handle, but depending on the job, you’ll still have plenty of options available such as thinner, spooled line; thicker, pre-cut line; serrated and square lines; or you could even use blades or chains.
