Easy to assembly. Has more power at idle then my old electric had at full power. I bought the premixed fuel with it and could not be happier. Follow the starting instructions and it runs right away with very few pulls. No smoke but average noise.

Most helpful negative review

Bought at Walmart used 1 time, was hard to start and get running. After first use havent been able to start again, wasted 75 dollars on piece of equipment wont buy another one ever

This has been really good weedwhacker. Sometimes I had to advance the string manually as it jams. When our lawn mower broke I actually used it to cut the entire, overgrown lawn. Twice. I also use the 40:1 premixed fuel mix in it. Overall, I’m very happy with this purchase.

If you follow the starting instructions to the letter, this thing starts right up. it is a 3 step process so be patient. powerful. i added a shoulder strap to carry the weight while using. one more tip. make sure to use recreation gas without ethanol and mix it with synthetic 2 stroke oil (supplied) at 40:1. avoid ethanol.

These eaters work well. The string refill process is not easy at first, WD 40 Spray your line to prevent snagging. Also, us plenty of high quality oil in the gas25/1 as on a hot day I once had my rings stick in the piston, but walmart gave me a new machine. Since then, nothing but great functionality at a great price.

Quite surprised at the quality and feel for the price. The enclosed manual says MTD Inc, all well renown lawn equipment manufacturing company so it’s of good quality. The overall length of the unit is a little cumbersome for a 6 foot tall guy like me BUT it is doable and runs very strong for a budget weedeater. That’s why I’m giving it 5 stars.

Great for what it does! This is actually a TroyBuilt Trimmer with the stupid name “Hyper Tough”. It’s a nice little trimmer for the household and small backyard. You will have to get the 40:1 fuel for this. Forget the mixing the gallon with the oil. It’s messy and not worth your time. The carburator would also get gunked up after a while if you do that. I bought this for a second home where yard maintenance is minimal. I recommend it will work well and with the 2 year warranty it should last about that long. For the price of it, it’s worth it better than those silly battery powered units. When you’re doing serious yardwork you need gas-powered unit. Oh also, on the box it says “gasoline powered” however they should say it needs the 40:1 fuel, kind of misleading, but then again what do you want for 80? Overall I recommend and I’m very satisfied with it. Lastly, if you need a professional version of this get a Husquarna or STIHL unit which are more powerful and better quality.

This weed eater runs decent when it runs, but don’t turn it off to take a break or accidentally stall it out by hitting a fence or object because you’ll never get it restarted. I purchase one and my neighbor purchase one a week after I did. I wish I could have talked to him before he purchased because now we both have weed eaters that don’t work properly. trust me when I say it will drive you crazy trying to restart it and I know what I’m doing I’m not a beginner at yard work by all means. I cannot figure it out it’s just a defective build or bad manufacturing. you could try everything under the sun and it will not restart until it sits for about 8 to 10 hours. strangest thing I’ve ever seen. Anyway purchase at your own risk don’t say I didn’t warn you. and on another note I purchased mine on March 29th tried to return it to Walmart on May 5th and they wouldn’t accept it because it was over 30 days. I still have my receipt and purchased the 2-year protection plan. I tried to call the manufacturer and they told me I had the wrong number so I called back the same number and the girl told me they handle drills chainsaws and other power tools for Hyper tough but not the weed eater gave me another number. call that number sent me to a mailbox that was full. better luck tomorrow I guess.

First things first. Every 25cc weed whip between under 200 is the same motor and carb. People have issues because they trust the fuel. DON’T USE REGULAR PUMP GAS! Use recreation fuel or if you don’t like mixing your fuel and oil buy the premixed ethanol free cans. the carburetors on small engines are sensitive and can get gummed up quick. Regular pump gas cannot last very long in a gas can. Since they added ethanol to it, it attracts moisture causing the problems the bad reviews have had. How do I know you ask. I’m a small engine mechanic and work on this stuff every day. 90% of the service work we do could of been avoided by people using recreation fuel instead of regular pump gas. I included a fun pic of a carb on a 300 weed whip that I had to give it a heated sonic bath for half a day to clean the ethanol enriched regular fuel out of its jets to get running.

I bought this Hyper tough weed trimmer last fall with 2 cans of pre mixed fuel from Walmart. I finally used it last week and yesterday (6/14/19) at a park where I walk my dogs. The trails in the back of the park are not maintained and the weeds were growing over the trails. I’m talking about foxtails, and other weeds that were, in some places three feet tall. The Hyper Tough has its operating instructions printed on the engine and are easy to follow. The first time I started it, it took around 10 pulls during the first 2 stages. Once it was running, it never died. The 2nd time I used it, it took like 5 pulls to start. Too easy. Anyways this weed trimmer is a BEAST. I mean for 70 bucks, wow, it blasted through the weeds like nothing. And I was cutting many of the weeds with half throttle. With full throttle, this thing was cutting through vines and small shrubs like they were weeds. It didn’t care. There were also dozens of pine cones on and around the trails and at first I was picking them up and throwing them, but got lazy and just cut through them. It was hurling them several feet, dang impressive. And I cut most of the first area with less than 2 tanks of gas. I posted a photo of the area to show what I was dealing with. I cut a bunch of weeds on the other side yesterday and was a breeze. Using premixed gas is the way to go. I would strongly recommend this weed trimmer. I put it to the test and was not disappointed.

Straight Shaft vs. Curved Shaft Trimmer – Which is Better?

When it comes to keeping your lawn in prime condition, you know that you’ll need a trimmer to handle the edges. But while picking one out for your home or business, you likely noticed that there are both straight shaft and curved shaft models available. Both look like they can do the job, but which is best suited to your needs?

It’s hard to know without taking each trimmer for a test run. But there are some key features of both straight and curved shaft trimmers that can be compared all the same. This guide will make those important comparisons while also teaching you the role the shaft plays in a trimmer’s operation.

After reading this guide, you won’t need to debate between straight shaft vs. curved shaft trimmers. You’ll understand which is more appropriate to your needs at a practical level. You’ll also understand which style is more affordable, which is key for folks working on a budget.

The Role of the Shaft

Before comparing straight and curved shafts trimmers, let’s take a moment to understand the shaft’s role in the trimmer overall. To start, the shaft acts as the main body for this kind of appliance, regardless of whether it is gas, electric, or battery-powered. As such, you’ll find the handle and throttle mounted at one end and the spinning head at the other.

The shaft doesn’t just support these elements externally, though. A trimmer’s shaft is also hollow, thus allowing all of the unit’s electric work to run through its interior. These wires and cords take on different forms between straight and curved shaft trimmers.

On a straight shaft trimmer, these wires run directly from the handle to the head. As such, they are less susceptible to bending.

On a curved shaft trimmer, though, these wires are automatically curved as they run down the length of the unit. This curve causes those wire bundles to flex just a bit when the unit is in use. Over time, this can decrease their flexibility and make them more prone to breakage.

In a more practical sense, a trimmer’s shaft shape also impacts the unit’s overall balance. This is because a trimmer’s extended length can cause a user to become fatigued over the course of its use.

Straight shaft trimmers are known to be a bit harder to handle without a harness or extra grip points. Curved shaft trimmers, on the other hand, are better balanced. Often, they can be held for longer periods with causing excessive user fatigue.

Be sure to keep these primary functions in mind while deciding whether a straight or curved shaft trimmer is most appropriate for you.

Key Features Compared

When it comes to comparing straight and curved shaft trimmers, there are a number of key specifications and features to compare. Each tells you a bit about those units’ general usability, which is crucial when working with this kind of outdoor maintenance equipment.

Each of the following comparison points also provides you with information about each trimmer type’s value as an investment. You’ll want your chosen trimmer to meet your needs for a decade or more, so it is worth your time to determine which shaft type is best in advance.

For more information on key specifications and features to look for in your next lawn trimmer, check out this video guide.

Weight and Balance

First and foremost, you can compare straight and curved shaft trimmers based on their weight. In most cases, curved shaft trimmers are slightly lighter. This is true comparatively among gas-, electric-, and battery-powered units. Straight shaft units, meanwhile, tend to weigh a little extra due to their extended length.

This then leads into another aspect worth comparing – balance. Balance is essential for trimmers due to the manner in which they are used. To be specific, their long length can cause excessive fatigue if the unit is not an ideal balance for its user.

Most professional and amateur trimmer users agree that curved shaft models have the best balance. This is due to their decreased weight, as well as their shorter length caused by the unit’s hook curve.

Curved shaft models also tend to have handles closer to the fulcrum or balance midpoint, making it easier to support the unit’s load during an extended trimming session.

In lieu of ideal balance, your chosen trimmer should at least provide some auxiliary support for its weight and balance. For many straight shaft models, this comes in the form of an over-the-shoulder strap harness. It may also come in the form of an adjustable forward handle.

hyper, tough, curved, shaft, string

In all cases, you should ideally check a unit’s balance before purchasing it. This can help you understand if your height is a good match for that trimmer’s length. If they are not, you’ll find your new trimmer to be unbalanced and likely unwieldy each time you start it up.


Maneuverability is another key specification that you won’t likely see listed on a trimmer’s box. But all the same, it has a major impact on how that trimmer performs in its intended locations.

In practice, maneuverability acts as an extension of a trimmer’s weight and balance (explained above). That is to say, if a trimmer is well-balanced and not too heavy, it is likely to be easier to maneuver its head around various obstacles.

Maneuverability can come in different forms, though. In one sense, a maneuverable trimmer should be able to work around natural curves such as those at the edge of a flower garden. This kind of maneuverability is best provided by curved shaft trimmers.

Meanwhile, a maneuverable unit should also be able to reach extended distances without requiring over-exertion. This may come in handy when trying to trim under a patio or within a brush line. In almost all cases, a straight shaft trimmer will provide you the extra length you need to achieve this kind of maneuverability.

Your chosen trimmer may not exemplify both kinds of maneuverability, and that’s okay. You’ll just need to appraise which kind of maneuverability you’ll need more and choose a unit accordingly (more information on choosing the right trimmer can be found below).

Core Power

Given the task at hand, you’ll naturally want a trimmer with enough core power to slice through any weeds or grass that stands in your way. But to do that, you’ll need an appreciable amount of power at your trimmer’s core.

To be specific, you’ll want to choose a unit with a strong motor that can maintain a unit’s rotational speeds reliably. This can be measured through several different metrics, though HP or “horsepower” is the most common. In almost all cases, more HP indicates that trimmer, whether straight or curved, has more capacity to operate than those with less HP.

While much of this capacity to operate originates in the motor, it isn’t the end of the story when it comes to trimmer power. In fact, a gearbox can also cause a unit’s torque to increase substantially compared to units without a gearbox.

Most popular brands include a gearbox on their straight shaft trimmers today. As a result, their basic and practical power is usually greater. This is why straight trimmers are the norm in industrial and commercial applications.

Meanwhile, curved shaft trimmers usually lack a gearbox and provide less torque, in turn. This decrease in power is seen as a tradeoff for the enhanced balance of these trimmers. Most residential users don’t need a ton of torque anyway, so they tend to gravitate toward curved shaft units for their other worthwhile specifications.

Cutting Head Options

Most trimmer users are familiar with their unit’s primary cutting head. Most commercial and personal trimmers use a string trim head by default. But there are more options available to trimmers with proper compatibilities.

For example, some trimmers can be equipped with special metal blades to facilitate underbrush trimming. These blades are heavy relative to a trimmer’s capacity to secure the blade at high speeds. As such, not all units can handle them or even provide a proper mounting location for them on their head.

It is more common for a straight shaft trimmer to provide this kind of compatibility. This is especially true of units designed for industrial use, where heavy-duty blades are routinely implemented. As such, an individual who wishes to have options when it comes to trimming and weed whacking may find a straight shaft model suitable.

However, for folks who only intend to trim lawn grass, a string-based trim head should suffice. These can be used on both straight and curved head trimmers, regardless of their length. This “string” is actually made from plastic, which can spin at higher speeds without the need for as much torque.

Also, curved trimmers tend to provide more options within the string-based head family. That is to say, many curved shaft trimmers provide 2 or more options when it comes to compatible trimmer string diameters. This can make it easier to adjust a curved shaft trimmer’s cutting strength without needing to switch out a heavy blade set.

Price and Longevity

Finally, while comparing trimmers, be sure to appraise the price and overall value of your prospective models. This analysis should take into account the cost and benefit of purchasing a model that can last through many seasons of use. This may even include taking into account a trimmer’s core durability.

When it comes to price, curved shaft trimmers tend to be cheaper. On average, curved trimmers tend to start at around 30 cheaper than their straight shaft counterparts. This can make them ideal for residential users and commercial buyers on a budget.

Meanwhile, straight shaft trimmers tend to cost a bit more on average. However, their construction often makes them able to resist wear and tear more efficiently. This allows them to remain productive for longer in turn, making their longevity a real feature for them.

Also, don’t forget to factor in long-term upkeep costs for your new trimmer. For example, units that use string line will require replacement line regularly given that those lines degrade with regular use. This price can be greater yet if your chosen model requires a name-brand line or an unusual gauge that is hard to find in stores.

Choosing the best string trimmer Option for You

When it comes time to choose between a straight and a curved shaft trimmer, there are a few factors you should take into account. These will allow you to obtain a workable model on the first try without even needing a test run.

First and foremost, consider your budget. There are many competing brands in today’s trimmer market. As such, you are sure to find a worthwhile model with your chosen shaft type, regardless of your pre-determined price range.

Next, consider your past experiences. If you know you have been very fatigued by trimming in the past, consider getting a curved trimmer or a straight trimmer with a support strap.

Along these same lines, you should consider your height. Shorter users tend to find a curved shaft unit easier to use. Meanwhile, tall users are more able to use a straight shaft unit successfully without need to bend or hunch over.

Finally, consider what kinds of grass or weeds you’ll need to trim going forward. If you intend to trim thicker weeds or very tall grass, a trimmer with a larger motor or gearbox may be warranted. Meanwhile, most residential lawns can be maintained with a small to medium motor at most.


The debate between straight shaft vs. curved shaft trimmers remains as present as ever. But you now have the information necessary to determine which type of trimmer is right for you. importantly, you’ll be able to pick out a high-quality model in no time flat using the key specifications and features explained in this guide.

However, if you’re still looking for recommendations regarding specific models, we have a few to offer. For example, the Remington RM25C remains a popular option for folks looking to pick up a well-equipped curved shaft trimmer.

Meanwhile, folks looking for a great straight shaft trimmer can turn to the Husqvarna 128LD. While it is a pricy pick, this model’s durability and performance in high capacity situations is simply unmatched.

Straight vs Curved Trimmer: What’s the Difference?

Home » Straight vs Curved Trimmer: What’s the Difference?

If you are on the lookout for a new weed eater, you will have noticed that there is a very large selection to pick from. To narrow the choice, you will probably be considering factors like power source, brand single or double string and many others.

Walmart Hyper Tough weed eater trimmer review

Another question you might be asking is whether you should go for a straight trimmer or a curved one. What are the differences between the two and which model is best suited to your needs? Here, we will look at the straight vs curved trimmer debate to help you pick the best option for you.

The basic differences between Straight vs Curved Trimmer

Whether you choose a gas weed eater or a battery powered 4 Cycle String Trimmer, there are three main differences between straight and curved trimmers. The first is obviously the angled head itself; the second concerns the size and weight of the tool while the third has to do with the internal workings. Let’s have a look at these general points first.

Size and weight

In general terms, straight trimmers are the larger and heavier models. This means they give you a longer reach, but since they weigh more, are more of a pain to carry around. Curved trimmers, on the other hand, tend to be smaller and lighter.

Drive chain

The drive chain is what connects the motor to the head and causes the strings to spin. In a curved model, the drive chain needs to bend, which can have an adverse effect on durability, making straight models the longer-lasting of the two types.

Curved head

The curve itself makes a curved version easier to manage and generally more comfortable to hold while working. However, they are more difficult to keep level, and a straight version is also better at reaching around or under obstacles like garden furniture.

The advantages and disadvantages of each type

Now let’s have a look in more detail at the advantages and disadvantages of straight vs curved trimmers.

Curved trimmers – what’s good

Curved trimmers are lighter, better balanced and easier to wield. They are simpler to use for general yard maintenance and are more suited for lighter work that requires more precision than power.

Since they are light and easy to manage, they are more suitable for jobs where you need to work for a long time since the unit itself doesn’t weigh as much and won’t give you sore arms or a stiff back.

Being smaller, they are easier to store and easier to transport, making them a better choice if space is limited or if you need to travel to different locations.

They also tend to be the less expensive choice, allowing you to save a bit of cash.

  • Lighter, better balanced and easier to use
  • Easier to transport and store
  • In general, less expensive than straight trimmers
  • Good for precision work
  • Simple to use

Curved trimmers – what’s not so good

Due to the curved head and the need for the drive chain to bend, curved trimmers are likely to have a shorter lifespan than straight trimmers.

For the same reason, they also tend to have less torque and so deliver less power to the cutting strings. This makes them less suitable for more heavy-duty jobs.

They may be simpler to use, but in general, they are not compatible with accessories – you can’t attach a pole saw or and edger as you can with some straight models, for example.

Another disadvantage is that the curved head makes them more awkward for cutting around obstacles. If you need to trim underneath garden furniture, it will be more difficult with a curved trimmer.

Since they are generally shorter, they offer you less reach, and they are also more difficult to keep level. Taller people might also find themselves bending over a lot with a shorter tool.

Straight trimmers – what’s good

Straight trimmers are generally longer, giving you better reach while you are working. This will also mean less bending, something that is particularly important for taller gardeners.

Since the drive chain is straight, they also give you higher torque and deliver more power, making them more suitable for tougher, heavy-duty jobs.

Due to the fact that many straight trimmers can accept different attachments, they are more versatile than curved trimmers, which can only be used in one way.

The straight shaft also means the drive chain is under less stress since it doesn’t need to bend, which also tends to mean straight trimmers last longer.

Straight trimmers – what’s not so good

Straight trimmers also have their drawbacks. For a start, they are heavier and more difficult to control, especially for smaller gardeners or those who don’t have the strength to wield a larger tool. They are also less well balanced than their curved counterparts.

hyper, tough, curved, shaft, string

In general, they are the more expensive option so might not be the right pick if you are looking to save money.

Finally, due to the angle, they also tend to kick up cuttings and debris much more than curved trimmers – you’ll need to wear the right clothing and protective equipment.

Which one to choose?

There is no “best” option, just one that is most suited to your needs. Now let’s have a look at which one you should choose.

Who should buy a curved trimmer?

Curved trimmers are ideal for people who have smaller yards to take care of and who need a trimmer for more infrequent use. If you only need to use the tool once every week or two, a curved trimmer might be best.

They are suited to light-duty work, so if you only need to deal with easy-to-cut grass or weeds, a curved model will be sufficient.

They are more appropriate for smaller or shorter people and are squarely aimed at the casual home user rather than the professional or semi-professional gardener of landscaper.

Who should buy a straight trimmer?

Straight trimmers are better if you need to deal with more heavy-duty tasks involving thicker weeds and undergrowth. They are also more suitable for people who use need to use the tool every day since they will last longer and provide more power.

They are better for taller people since it will save them having to stoop to use their trimmer, and in general, straight trimmers are the go-to choice for commercial-grade users.

Both great tools – but choose appropriately

We can’t say that one type of trimmer is better than the other – all we can say is that each is better suited to certain situations. When choosing between the two types, think carefully about the jobs you need to use it for as well as your own physical capabilities and you are sure to pick the right one for you.

Grass and weeds can grow up the side of the shed, encroach on the garden, and climb the fence, but with a gas string trimmer—commonly called a weed wacker—unwanted plants can quickly and efficiently be removed. This garden tool is a helpful addition to a large yard or any location with a lot of different obstacles, like trees, lawn ornaments, fencing, garden beds, and small structures. While battery-powered trimmers may be a good choice for light trimming in small yards, gas string trimmers have the power that’s ideal for cutting through dense grass, weeds, and brush.

The best gas string trimmer for your yard will depend on several important factors, including cutting width, shaft type, and engine size. Ahead, we discuss these and other important considerations that went into choosing the trimmers we tested for this article. Later on, we will share more details on the individual models and how each one performed for us. The following list includes some of the best gas string trimmer tools available.

  • BEST OVERALL: Echo SRM-225i
  • RUNNER-UP:Husqvarna 330LK Gas String Trimmer
  • BEST BANG FOR THE BUCK:Ryobi 2-Cycle Straight Shaft String Trimmer
  • BEST CURVED-SHAFT:Husqvarna 130C Curved Shaft String Trimmer
  • BEST LIGHTWEIGHT:STIHL FS 40 C-E Gas String Trimmer

How We Tested the Best Gas String Trimmers

Shopping for a string trimmer reveals that statistics can only forward the search so far. Regardless of the engine size, machine weight, shaft length, and other measurables, much of the tool’s effectiveness depends on the operator’s physical build and personal preferences, along with the type of trimming to be done. To learn more about the trimmers on our list, we field-tested them in a variety of settings.

We spent 2 days testing the gas string trimmers in this article on regular lawn trimming, close-quarters trimming among shrubs and perennials in landscape beds, and mowing an overgrown field. After unboxing and assembling each trimmer, we filled the fuel tank and got started.

Our initial notes included measurable and easily observable features, such as each machine’s physical size and weight, whether it had a straight or curved shaft, and whether or not it could be used with other tool attachments. The first operational tests were simply to start each machine and note the number of pulls required to get started.

We then used each machine for 30 minutes of field mowing and 15 minutes each of lawn trimming and landscape bed trimming. In each setting, we noted perceived cutting power, responsiveness to triggering, responsiveness to bumping out new trimmer line, operator comfort, and whether or not refueling was necessary to complete the project. Finally, we reloaded each cutting head with trimmer line and noted the difficulty.

We recorded our field notes and used a scoring rubric to organize the trimmers with award titles for this guide.

Our Top Picks

The lineup of gas string trimmers was chosen based on the individual safety features, attachments, and engine type as well as product quality and the other important factors mentioned above. The following products were tested in situations DIYers are likely to encounter on their property and proved to be among the best gas string trimmers for keeping the yard and garden neatly trimmed.

Echo SRM-225i

Our top pick proves the adage, “You get what you pay for.” The Echo SRM-225i string trimmer costs a little more than some of the competitors we tested, but it delivered the best combination of easy start-up, overall working comfort, and grass trimming power at a reasonable price.

Powered by a lightweight, high-output 21.2cc two-cycle engine, this trimmer cuts with satisfyingly aggressive results in dense grass and coarse weeds, and uses less fuel than competitors with larger engines. It makes a 17-inch cutting swath and features a speed-feed head that reduces the time it takes to reload the trimmer line by half. The 59-inch straight shaft offers excellent reach beneath shrubs and into tight corners. The weight-balanced design, rubber overmold grip on the handles, and ergonomic throttle trigger reduce operator fatigue for extended use.

No assembly was required to get started with the Echo straight-shaft string trimmer. The position of the fuel tank made it easiest to fill with the motor elevated. Using a 1-gallon fuel can, we held the trimmer in one hand while pouring with the other. Following the start-up instructions printed on the machine, it started on the third pull of the recoil cord.

We were pleasantly surprised by the way the smaller-than-average motor powered this trimmer through coarse vegetation and even small, woody stems. Performance exceeded the 25cc trimmers we tested and rivaled the 27cc models. The weight of the motor was well balanced by the long, straight shaft, so maneuvering was very easy and comfortable, even after an hour of use. The rubber grips on the handles deadened any vibration so that we didn’t experience the hand fatigue or numbness that sometimes comes with hours of weed wacking. Though not the most powerful brush-cutting string trimmer we tested, this Echo model makes the best case for general trimming and frequent, larger cleanup projects.

  • I-75 ignition system reduces start-up effort
  • Speed-feed head makes adding trimmer line easy
  • Spool can’t be wound in the wrong direction
  • Anti-vibration design; cushioned front and rear grips
  • Compatible with heavy-duty.095 trimmer line

Get the Echo SRM-225i gas string trimmer at Amazon, The Home Depot, or Mowers Direct.

Husqvarna 330LK Gas String Trimmer

The Husqvarna 330LK Gas String Trimmer offers heavy-duty capability for trimming, edging, and other yard-care tasks. It features an attachment-compatible shaft that comes with the high-capacity Rapid Replace trimmer attachment and is compatible with lawn-edger, hedge-shear, and pole-chainsaw attachments. Spring-assisted recoil starting, a powerful 27.9cc two-cycle engine, and customizable trimming swath make this multitasking trimmer one of the top performers in our tests.

While it offered similar benefits of reach and power as the other straight-shaft trimmers, the Husqvarna attachment-capable trimmer stood out in our tests in terms of controls and overall feel. The auto-return on-off switch defaulted to the “on” position, and the pull-out choke lever made it obvious which position was for cold starting versus running—two points of confusion on many trimmers.

The spring-assisted recoil starter took some getting used to. There was a catch point mid pull, before which we could feel resistance slightly intensifying, but afterwards the power-assist mechanism released. Overall starting was easy (never more than three pulls), and the motor ran relatively quietly (although we wore over-the-ear hearing protection for the tests).

Powered by the largest motor in our test group, the trimmer did a fantastic job cleanly snipping the tops of wayward grass blades and hogging through heavy overgrown weeds. The vibration-dampening system seemed to reduce hand fatigue, but after an hour of operation, the machine’s weight was more tiring overall than the other trimmers. Adding a harness system could help for bigger jobs. This model seemed like a really good fit for those who want to get the most production from a single machine, with plenty of power for a wide range of tasks.

  • 27.9cc engine delivers more power for tough cutting conditions
  • Spring-loaded Smart start and air purge for easier cold starting
  • 20-inch-wide cutting swath reduces trimming time
  • Compatible with Husqvarna power-head attachments

Ryobi 2-Cycle Straight Shaft String Trimmer

For those just starting to build their outdoor power-tool collection, a reliable and budget-friendly choice makes sense. The Ryobi straight-shaft string trimmer delivers plenty of power to knock down grass and weeds, and it’s attachment capable for punching out more yard chores beyond just trimming.

This trimmer features a 25cc two-cycle engine and includes the “reel-easy” Rapid-loading trimmer head. The shaft is compatible with Ryobi expand-it attachments, including the lawn edger, cultivator, pole chainsaw, leaf blower, and hedge shear, sold separately.

The Ryobi string trimmer was ready to go within 5 minutes. Out-of-the-box assembly required attaching the debris guard above the cutting head and inserting the attachment into the power-head shaft. When we added fuel, we noted that the tank’s opening was quite small, so we had to pour very carefully (or use a funnel) to avoid spills. Also, the opening is oriented horizontally, which could pose a leak problem with age but was not a problem for us.

For the low price, we were impressed with this trimmer’s performance. It tore through weeds and grass with a similar effect as the more expensive models. But this machine was significantly louder and vibrated more than the pricier competition. We also noted that the Ryobi was one of two machines in our tests that did not run a full hour on a single tank of fuel—we had to refuel at about 55 minutes. But for anyone on a budget, this weed wacker makes quick work of trimming jobs and may save money and storage space when other attachments are added.

  • Ample power for trimming and edging; suitable for both thick and thin plant and grass varieties
  • Works with hedge-shears, lawn-edger, or pole-chainsaw attachments
  • Easy to maneuver into hard-to-reach areas

Even at a premium price point, landscape pros and commercial property managers choose STIHL string trimmers and brush cutters for their combination of power, durability, and operator comfort. The STIHL FS 70 R commercial-grade straight-shaft string trimmer features a fuel-efficient 27.2cc two-cycle engine to go along with its rugged but lightweight polymer housing. To protect the environment and the health of workers, this trimmer earns the STIHL “Caring For Nature” rating as a low-emissions trimmer that operates cleaner than Environmental Protection Agency requirements.

Among the trimmers we tested, the STIHL models were more expensive and a little harder to get, but worth it. STIHL only sells through its network of authorized full-line servicing dealers, so online ordering is limited and home delivery is generally not available. But the process eliminates out-of-the-box start-up problems because a certified technician assembles, tests, and adjusts the machine at the dealership prior to customer pickup.

Our first note on this trimmer was that the fuel-fill opening is conveniently wide and extremely easy to access, even while the machine is resting flat on the ground. For our tests, the FS 70 R started on the first pull. It ran noticeably smoother than any of the other machines, both at idle speed and at full throttle, with delay-free acceleration when triggered. The trimmer cut cleanly through tall grass and densely overgrown weeds without getting wrapped up or bogged down in debris. As for fuel efficiency, even with the modest 11.5-ounce fuel tank, we were able to trim for a full hour without stopping to refill. The AutoCut trimmer head was fast and easy to respool without disassembly.

Another point for consideration was the overall operating comfort. Not only was the FS 70 R the lightest straight-shaft trimmer we tested, but it also came with a shoulder strap that transferred all of the machine’s weight away from the hands. As a total package, this would be our machine of choice for all-day trimming on large properties.

  • Very lightweight design; easy to maneuver design
  • Carry strap for extended-use comfort included
  • Protected choke lever reduces risk of damage in transport
  • Easy-access air filter for quick clean out or replacement
  • High-power engine and excellent fuel economy increase work productivity

Husqvarna 130C Curved Shaft String Trimmer

This Husqvarna gas trimmer has a curved-shaft design that is intended to make it easier to cut parallel to the ground. The trimmer features a bump feeding system, enabling the user to extend the string from the dual-line head by tapping the trimmer head against the ground.

The two-cycle gas string trimmer is a good option for homes with small to medium yards, as it weighs just 11.8 pounds and has a 17-inch cutting width. It protects the user with a debris guard cleverly designed with a narrow extension from the shaft widening to a broad, protective shield; this combination makes it easier to see where the trimmer is cutting without sacrificing safety. The trimmer also has a trigger safety switch, which must be activated before the variable speed trigger will respond, helping prevent accidental start-ups.

The Husqvarna curved-shaft trimmer weighed less than most straight trimmers but a little more than the other curved shaft trimmers in our tests. It arrived ready to work, with no assembly required. After filling the fuel tank, it started on the third pull and delivered powerful and surprisingly quiet performance.

The molded fuel cap was easy to grip, and the tank mouth was wide enough to fill easily. We found it convenient to rest the engine on an elevated surface for refueling. The spring-assisted recoil starter made starting easy—typically on the second pull in our tests. The trimmer easily mowed down all of the coarse weeds and thick grass in its way. We loved the responsiveness of the bump cutting head, which seemed to feed more easily than most of the other trimmers we tested. For curved-shaft enthusiasts with small to midsize yards, this could be a great choice.

  • Surprisingly quiet operation for such a powerful engine
  • Plenty of power to whack coarse weeds and thick grass
  • Curved shaft comfortable for users under 6 feet tall

STIHL FS 40 C-E Gas String Trimmer

Curved-shaft trimmers are touted for the weight reduction that comes from a shortened shaft—but they often place more weight on the user’s rear hand, which can increase operator fatigue. Weighing less than 10 pounds, the STIHL FS 40 C-E Gas String Trimmer pairs the lightest design in our roundup with a shoulder strap that transfers the load to the operator’s core. The result is a major upgrade in extended-use comfort for curved-shaft trimmer users.

This machine also excels in trimming performance. The 27.2cc engine runs clean and smooth, delivering commercial-grade cutting power, excellent fuel economy, and low exhaust emissions. It has earned STIHL’s “Caring For Nature” seal for exhaust emissions that outperform EPA standards.

We were pleasantly surprised by the bargain price on the STIHL curved shaft trimmer—just a few dollars more than our Best Bang for the Buck pick. It was worth every penny. As with the other STIHL trimmer on our list, this model was assembled and tested at the dealership before we picked it up. Both machines are built with the same engine type.

The FS 40 C-E started on the first pull and tore through all of the grass and weeds in its way without hesitation. The engine ran and accelerated very smoothly throughout testing, with a crisp response to triggering. We cannot overstate the value that a shoulder strap adds to this curved-shaft design. The other curved trimmers we tested left us with heavy right arms from carrying the weight of the motor after an hour of trimming, but this STIHL did not. In fact, the shoulder strap increased overall maneuverability by providing a pivot at the attachment point. Arm and shoulder muscles were used only to guide the direction of the trimmer. This makes an excellent pick for any curved-shaft trimmer user, especially those faced with hours-long jobs.

  • Budget-friendly price for industry-leading performance
  • Very light weight, plus shoulder strap to further decrease load
  • Easily cuts through dense grass and coarse weeds
  • Very low exhaust emissions for a reduced environmental impact

Craftsman 25cc 2-Cycle Straight Shaft Gas Trimmer

At 13 pounds, this gas string trimmer is considered lightweight, but it weighs a bit more than most of the competition we tested. It features a dual-line head that cuts a 17-inch swath, making this trimmer a good choice for yards up to 1 acre or for any locations where landscaping and lawn ornaments demand precision trimming.

The trimmer comes with a debris guard and has a multiposition handle that can be adjusted to the user’s preferred position for better control and comfort. It also features a bump feeding system so the available line can be extended by simply tapping the head on the ground. This trimmer has a straight shaft, and the head can be removed to make string loading easier. It works with other Craftsman trimmer attachments, which are not included.

In our tests, the Craftsman trimmer performed similarly to the Ryobi. Both featured no-frills design and powerful cutting action, and both were priced near the low point among our test group. Installing the debris guard and loop handle took about 5 minutes. We added fuel and were ready to start. This was the only trimmer we flooded by overpriming while attempting to start the first time. After waiting a few minutes, it started on the fourth pull.

The 25cc motor provided ample power to cut through thick grass and weeds. The cutting head was easy to reload with a new trimmer line. The machine ran a bit louder than the other trimmers we tested, and we felt more vibration in the handles. Still, because of its modest price, and especially because of its ability to power other tool attachments, this Craftsman string trimmer has a lot to offer budget-conscious homeowners.

  • Lowest price point of all trimmers we tested
  • Ample power for grass trimming and weed wacking
  • Attachment-capable shaft compatible with numerous yard-care tools
  • Easy winding bump head for fast trimmer-line reloads

Echo GT-225 Curved Shaft String Trimmer

The Echo GT-225 string trimmer makes yard work easier thanks to its lightweight curved-shaft design and professional grade 21.2cc two-cycle engine. Weighing just over 10 pounds, this trimmer is easy to carry and highly maneuverable—an ideal build for smaller yards. The two-line Rapid-loader cutting head trims a 16-inch swath and uses precut trimmer line for easy line changes.

The GT-225 curved-shaft trimmer arrived ready to work and no assembly was required. After adding fuel, which worked best with the engine resting on an elevated surface, it was ready to go. We noted that this Echo trimmer is powered by the same engine type as our Best Overall pick. It started easily on the second pull, accelerated smoothly, and delivered cutting power seemingly beyond its 21.2cc engine displacement.

As with the Husqvarna curved-shaft trimmer, the shorter shaft left a greater proportion of the machine’s weight in the operator’s rear hand. But the lighter overall weight made it a bit less tiring. One aspect of this trimmer that really stood out was the unique cutting-head design. It uses fixed pieces of trimmer line instead of feeding from a reserve spool. It cuts well, but when the trimmer line wears down, the operator must stop and reload. This design is most practical for small yards where multiple reloads will not be required.

  • Smooth-running, surprisingly powerful 21.2cc 2-cycle engine
  • Easy to maneuver in small landscapes
  • Durable and fuel efficient
  • Simple cutting-head design makes it easy to reload

What to Consider When Choosing the Best Gas String Trimmer

A string trimmer is a powerful tool equipped with weed-eater string to cut through overgrown grass and weeds quickly. For help deciding on the best gas string trimmer for your home’s landscaping, consider the following criteria: engine type, fuel efficiency and runtime, cutting width, feeding and loading, speed, ease of use, attachments, and safety features.

Engine Type

Gas string trimmers fall into two categories based on the type of engine they use: two-cycle or four-cycle. This seemingly simple difference creates significant gaps between efficiency, cost, maintenance, and power.

  • Two-cycle engines are lightweight, allowing the user to move more freely while working with the trimmer. Two-cycle engines use a fuel-and-oil blend, which reduces average maintenance to changing the weed-eater string and emptying the fuel tank before storing the trimmer for the off-season. Though lower maintenance, these trimmers have less power output than those with a four-cycle engine.
  • Four-cycle engines are generally considered more efficient than two-cycle engines. The efficiency comes at the cost of size and weight, so users should expect a heavier tool when they pick up a four-cycle engine trimmer. These tools also are more powerful than products with two-cycle engines, making them a good choice for yards that are more than an acre. However, products with four-cycle engines typically cost more and require regular oil changes to keep them working properly.

The size of the engine is another important factor. This is measured in cubic centimeters (cc). As an engine increases in size, as indicated by the cc, the power output of the engine increases. This is because a larger engine is generally capable of displacing more air and fuel at one time. When displacement is low, power output is also low. So if high power is the goal, look for a product with an engine larger than 40cc.

Fuel Efficiency and Runtime

Fuel efficiency can be difficult to gauge, as there are a number of different factors that can influence it, including fuel mixture, ambient temperature, operating speed, and even the type of grass or weeds being cut. However, a gas string trimmer with a four-cycle engine will usually be more efficient than a trimmer with a two-cycle engine.

Runtime is a bit easier to measure because manufacturers typically provide the fuel-tank size and the maximum runtime on a single tank of fuel. These runtime numbers are based on tests performed in ideal, controlled environments, so factors like high- and low-temperature extremes or very dense, wet foliage can reduce the actual runtime. These situations decrease the fuel efficiency of the trimmer, causing it to use more fuel in a shorter period of time.

Cutting Width

The cutting width of a gas string trimmer refers to the total width the rotating string can reach when the trimmer is in use. Standard gas string trimmers will have a cutting width of about 16 to 18 inches. However, there are compact models that may be as small as 12 inches wide and commercial gas string trimmers that exceed 20 inches wide, so it’s important to know what size is necessary for the lawn, yard, and garden.

Yards that exceed 1 acre and have very few small obstacles may benefit from a gas string trimmer with a cutting width of 18 inches or more, while yards that are smaller than 1 acre are fine with gas trimmers that have a smaller cutting width. Users with many obstacles in their yard may prefer a smaller cutting width so they can have more precise control. For cutting through deep, dense weeds and overgrown grass, it’s helpful if the cutting width is big and the engine is powerful.

Variable Speed Control

The speed of a gas string trimmer is controlled by a variable speed trigger that can either be placed on the shaft of the tool or on one of the handles (if the model has a split-handle design). Trigger placement on the right handle may cause problems for left-handed users. When the trigger is on the shaft of the trimmer, it’s relatively easy to use either hand to control the speed while the other hand controls the movement of the trimmer head.

Variable speed control allows the user to reduce the speed for light trimming or increase the speed to cut through dense brush and weeds more rapidly. The ability to dial down the speed for precision control is great while trimming around lawn ornaments, garden beds, and along fencing to reduce the potential damage that can be caused by less controllable trimmers.

Loading and Feeding

Loading and feeding the line tend to be the most challenging parts of using a gas string trimmer. Loading refers to installing the cutting string, which can be difficult, especially when dealing with a dual-line head that has two weed-eater strings. To help make this task easier, shoppers will want to consider products with a detachable head so they aren’t fighting with the entire trimmer while trying to change the line.

Feeding the line refers to pulling more line out of the trimmer head. There are now many products that offer innovative line-feeding methods that eliminate the need to start and stop while using the trimmer to deal with a standard fixed line. These include bump feeding and auto feeding.

  • Fixed-line gas string trimmers are attached tightly to the head, meaning the user needs to loosen the head and manually pull the line out when more is needed.
  • Bump feeders are designed to push out more string when the head is bumped on the ground or on another hard object so the user needn’t stop to extend the string.
  • Auto feeders have a prewound head that automatically feeds string using centrifugal force, so the string is constantly self-correcting to the ideal length.

Ease of Use

Using a gas string trimmer can be tiring, but several factors can help make the work easier. These include the angle of the shaft, the weight of the string trimmer, the balance of the trimmer, and the trimmer head.

  • The shaft of the trimmer can either be completely straight or curved. Curved shafts are great for getting a flat angle cut over a broad area without having to bend and twist to change the cut of the trimmer. Straight shafts are better for detailed trimming between and around lawn ornaments.
  • The weight of a trimmer can tire the user, especially if working in a very large yard or dealing with many different precision cuts. Additional time spent trimming can lead to aching arms and shoulders, so a lighter trimmer of 10 to 12 pounds may be a better option. If the power of a heavier trimmer is needed, then work breaks may be necessary to avoid injury.
  • The balance of the gas string trimmer is dependent on how the weight of the engine, focused at the rear of the tool, compares to the weight of the rest of the trimmer, which is dispersed along the entire length of the shaft down to the head. Unfortunately, balance is difficult to determine without actually holding the tool, so be sure to read product information and hands-on reviews, such as the ones that appear here, to get a good idea of how the trimmer handles.
  • The trimmer head can come with a variety of attachments detailed below. It can also have a versatile tilting feature that allows the head to be angled up or down for more precise cutting in tight spots.


When using a gas string trimmer to clean up the yard and garden, it’s possible to encounter sticks, leaves, and debris; the trimmer is useless to deal with these unless it comes with an edging tool, saw, blower, or brush attachment.

  • Edging tools are useful for creating a defined edge between the garden and the lawn or the lawn and the sidewalk or driveway. They have a more powerful cutting blade that makes quick work of overgrown grass, which saves the time and effort of using a shovel to edge the lawn.
  • Saw attachments are a great choice for cutting through sticks and brush that have fallen during the fall and winter seasons. While it shouldn’t be used for cutting through logs or planks of wood, the saw moves easily through small branches and twigs.
  • Blowers are a separate tool, but sometimes they are packaged as a kit with a trimmer. They help quickly clean up a mess made by trimming, edging, and cutting.
  • Brush attachments can help clean up a messy sidewalk or driveway, pushing the yard debris into a pile or just brushing stray grass and dirt back onto the lawn.

Safety Features

Before picking up a gas string trimmer, it’s important to remember that this device is designed for cutting through layers of the tough cellulose fiber of plants while hitting walls, rocks, metal, and wood at an impressive speed. It is a machine that should always be handled with proper precautions. With this in mind, look for gas string trimmers that have safety features like a debris guard, a trigger switch, and a padded grip.

  • Debris guards are included with almost every gas string trimmer because they are essential to protecting the user. Even with a guard, some flying grass can escape, which is why users must wear safety glasses, long pants, and closed-toe shoes while working.
  • Trigger switches are designed to prevent the trimmer from being accidentally turned on. The trigger switch must be held down before the trigger will activate the trimmer.
  • Padded grips on the shaft and handle of the gas string trimmer will help reduce hand fatigue and muscle strain that can be caused by excessive vibration. The padding also makes the tool easier to hold and helps prevent it from slipping out of the user’s hand while trimming.


If you’re still unsure about some of the details surrounding gas string trimmers, read the following answers to some of the most commonly asked questions about how to use these trimmers as well as how to store and maintain these machines for years of use.

Q. What size gas string trimmer do I need?

When trying to decide on the right size trimmer, consider the size of the yard, the number of obstacles in the yard, and the type of obstacles. Generally, larger yards without many obstacles will be easier with larger gas string trimmers. Yards with gardens, low-hanging plant leaves, lawn ornaments, and fences are better handled with a smaller trimmer.

Q. How do you store gas string trimmer?

To keep it safe from hot- and cold-temperature extremes, precipitation, and debris, store a gas string trimmer off of the floor inside a workshop or garage. This can be done by hanging the gas string trimmer on the wall using two or more hanging hooks. Make sure to empty the gas from the trimmer before storing for the off-season.

Q. How long do gas string trimmers last?

Gas string trimmers can last about 5 to 10 years, with some difference in longevity depending on how the trimmer is stored and if it is maintained properly.
