Primary Considerations for Purchasing a String Trimmer

The Type of String Trimmer

When it comes to string trimmers, the most popular types include the following:

The Gas Weed Eater

The most significant advantage of the gas-powered models is that they come with enough power to get you through the heaviest of string cleaning jobs. Also, most of them come with a wide cutting path, so you can easily get your job done within a short amount of time.

Sadly, these options come with a lot of cons as well. For one, they tend to be heavier, which, according to research by the University of North Carolina, can easily cause a lot of injuries.

Also, gas-powered models tend to be very noisy. However, with earmuffs, you can easily fix this problem. You will also need to ensure that these products are always maintained (as regards their parts), and there's the additional cost of purchasing oil and gas.

The Two-Cycle Engine

If you are in the hunt for something that is affordable and which still has enough power to get you through tight spots, then you should look for a 2-cycle machine that comes with separate controls for the choke, primer, and throttle. Keep in mind that these products run on both gas and oil.

The Four-Cycle Engine

The 4-cycle weed eater comes with an engine that easily cuts through just about anything. In addition to that, these highly powerful machines are more comfortable to start, and they provide less environmental pollution. They don't require a mixture of gas and oil, and they are known to operate much easier than the 2-cycle motors.

As you probably guessed, they cost more.

Brush Cutters

If you want to flatten saplings and brush with a brush cutter, then you will need to have effective control. Most of the gas-powered trimmers can easily have handlebars put on them, although you should note that they don't really move as well when it comes to string trimming.

The Electric Weed Eater

The electric trimmers are one of the latest evolutions in string trimming technology, and just as it is with every other class of string trimmers, they have their pros and cons.

On the pros part, the string trimmers are very light. They also produce much less noise, and they are known to cost generally less.

On the flip side, they incorporate less power into their build, so they can't handle most of the toughest cutting tasks available. They also have shorter cutting paths, and the reach their cords is much more limited.

Battery-Powered String Trimmers

Known to be mostly cordless, the battery-powered string trimmers can easily handle weeds and grass in small areas, and they come with greater portability. Thanks to their rechargeable batteries, you won't need to deal with mixing gas and oil or have to tussle with pesky extension cords.

Sadly though, they don't have much power.

The Trimmer’s Operating Technique


If you hold a good string trimmer to close too the surface, it will be able to get the grass off in one fell sweep. So, it is always recommended that you have the string had about 2 to 3 inches away from the ground- like you would hold a mower blade- and move the machine from one side to the other in a steady motion.

It's possible that you don't get it the right time, don't worry! Everyone fumbles at first try. Just keep at it.

Dealing with Overgrown Grass

If you trim tall grass, it is possible for their stems to hang on the head of the trimmer and affect its performance, so, the best thing is for you to trim all weeds from the top right down. This way, you can rest assured that the string will cut the plants into smaller pieces.

Also, if you're working on a large field of grass, then you might want to get a unique head for grass cutting. These have three blades that are built for laying stems down, so that those stems don't end up affecting the cutting mechanism.

The height of the trimmer itself

This is another primary consideration when you're shopping for a string trimmer. As a tall person, using a string trimmer that is too short will cause you to bend more than you should, and according to an article by On Health, doing this consistently could lead to severe low back pains.


A lot of trimmers can easily be cleaned by wiping off the grass bits and debris that you cut off their blades. However, to be on the safe side, you can easily check through their manuals to know what the right maintenance methods are.


Storage might be a major deal-breaker for you as well. Some string trimmers can easily be stored, as they have ergonomic designs. Others, not so much. At the end of the day, your choice depends on whether you have the space to store a specific string trimmer.

In the word of weed eaters, the absolute top choice would have to be the Black & Decker GH900 String Trimmer.  This option features an ergonomic and lightweight design, and it makes light work of even the toughest and most stubborn weeds in your home.  

One of the best parts about this string trimmer is that it seems to come with just about every single element that you will need to create a proper edging job. It is commonly used in areas where the grass is a little hard to reach, as well as for maintaining the hardest surfaces. Safe to say, it does its job perfectly.

With it, you also get an adjustable height and a wide array of pivoting angle positions, all of which will ensure that you can get a proper level of control and comfort while handling it. You don't have to worry about being too tall or too short; with the GH900, you will be able to handle any edging and trimming tasks without any stress whatsoever.

Then, there's the motor. It measures 6.5 amps in power rating, and it comes with high torque transmission that helps it to assist in trimming through all of the toughest weeds effectively.

Also, thanks to the presence of a Power Drive Transmission, this weed whacker gets rid of all the usual bogging down that you get when working through the more massive weeds and grasses. The string trimmer also comes with an AFS automatic feed system that ensures you will be able to complete your edging and trimming process without having to stop and feed the pool.

The unit was specially designed to accommodate a 2-in-1 easy conversion wheeled edging. This will make it very easy for you to make the conversion from edger to trimmer and back. Also, with the inclusion of the Smart Edge mode, you will achieve a higher level of accuracy and control while edging, thereby being able to provide much straighter and neater edges on each project.

Things We Liked

Just as it is with the previous option, the Worx WG154 Cordless Grass Trimmer/Edger comes with the unique ability to make quick conversions between being a lawn edger and working as a trimmer. 

You can switch from edger to trimmer in a matter of seconds. The cordless weed eater comes with a one-touch, easy, no-tool conversion system that makes the conversion possible. Apart from that, you'll also be happy to know that this battery powered weed eater works with a 20 Volts Lithium-ion battery, which provides much more run time on a single charge.

A solid front handle provides extra control and comfort, although the fact that this handle doesn't offer flexible pivoting positions might mean that the ease of use on the cordless weed trimmer might be a little bit limited. Still, it's a small price to pay, especially when you consider the type of power that the edger comes with.

To make for the additional cutting path and run time, the WORX edger comes with a cutting width that can be adjusted from 10 inches to 12 inches. Essentially, this means that depending on the type of path that you are looking to clear for yourself, this option can definitely get you to do this much faster.

At least, you can forgive the lack of flexible pivoting positions with the inclusion of this feature.

Then, to top it all off, the unit incorporates a Folding spacer guard that will help you to cut without harming any of you ornamental landscaping or flowers.

Things We Liked

An adjustable cutting path will help you make more cuts in far less time

The unit has a powerful motor so that you can cut through a stubborn bush with ease

A Folding space guard can help to protect your flowers

Things We Didn't Like

You might find it a little uncomfortable to use, as it doesn't contain flexible pivoting positions. However, this shouldn't bother you so much.

From its name, you can already tell that there's something special about the GreenWorks Cordless String Trimmer & Blower. The combo pack provides both a blower and a string trimmer's functionalities, so you get a two-in-one tool that makes gardening much easier and much faster.

To kick things off, we take a look at the product's functionalities, the most significant selling point for this battery-operated weed eater would have to be its strength and battery performance. With a 2.0AH battery, it is capable of lasting up to 45 minutes on a full charge.

You'll also appreciate the lightweight build of this battery weed wacker, which in part is due to the detachability of the two separate tools. So, if you want to use the blower alone and not the string trimmer (and vice versa), you can simply have the products detached and work with them individually.

The GreenWorks trimmer also features an axial fan, which helps it to handle some of the toughest clearing tasks out there. However, when it comes to the string trimmer, its functions are a little bit finicky, so you might need a little time to get a proper hand of it. This trimmer itself is not able to handle tougher areas, so you might want to keep its use to the moderate grassy areas.

Things We Liked

A lightweight design makes it easy to carry

Long-lasting battery

An axial fan improves its functionality a great deal

Things We Didn't Like

You'll need some time to master its use

Coming in with a lot of aesthetic appeal, the Greenworks 10 Amp Corded String Trimmer makes for a great addition to your gardening tools without a doubt. 

Just as it is with almost every option on this list, the product has the lightweight feature locked down. However, a fun addition to that will be the electric start and cord lock, both of which see to it that the trimmer is even easier to start and use.

The design of this string trimmer is exceptionally intuitive. It features an over-mold grip and handle, as well as hand cushioning. These two will see to it that you feel more comfortable while handling the trimmer. An auxiliary handle will also provide additional control over your cutting path and the trimmer's operation

As regards power, the Greenworks 10 Amp Corded String Trimmer comes with a 10-amp motor and a .080 dual line bump feed. Its cutting path measures 18", so it helps to speed the trimming process up a great deal.

It has great customer reviews, which is also a testament to its efficiency and practicality. With its combination of design ingenuity and power, you should expect no less.

However, some people tend to have an issue with the lack of replacement spools. While the original spools work fine, they're quite susceptible to damage, and a lack of any replacement will mean that you have to order one from the manufacturer.

Things We Liked

It's comfortable to use

A very wide clearing path

Additional control over the clearing path is a bonus

Things We Didn't Like

No replacement spools available

This string trimmer might not be our overall pick but the Husqvarna Gas String Trimmer is made from a well-known company, with amazing features. 

Of all the functions this string trimmer provides, its ease of use will have to be one of the most interesting. As opposed to a lot of other available options, the choke and purge on this one are easy to understand and use, with straightforward controls.

SmartStart technology also ensures that the starter and engine are easy to use. So, the startup sequence for this one is as simple as it gets. 

You might not enjoy the fact that its startup is the conventional one (as opposed to some options that feature electric starting feature), but the simplicity that it comes with would definitely help to appease that.

Moving on, this gas string trimmer provides an X-Torq engine, which improves fuel use efficiency and helps to reduce the emissions of harmful exhaust fumes. This makes the string trimmer especially practical for people who have respiratory issues (or if you just have the smell of smoke!).

The handle of this gas powered weed water is easily adjustable, and it provides a soft grip for optimal comfort. However, this comfort is a tad undermined by the weight of the engine, which you will still need to bear as you carry the trimmer along with you.

Things We Liked

Comfortable and adjustable grip

Fuel-efficient X-Torq engine

StartStart technology for easier start sequence

Things We Didn't Like

The engine is a bit bulky

The Greenworks Pro 80V Cordless String Trimmer might not be the highest-ranking cordless string trimmer the manufacturer, but there is no doubt that this option here will make for some fantastic use.

The string trimmer comes with an attachment-capable power head which provides additional versatility to the unit. If you need power and you're pressed for time, you'll be glad to know that the trimmer has a variable speed trimmer.

The manufacturers of this product also put a lot of stock in comfort, as they made the cordless trimmer to be light and very easy to use. Durability is another aspect where the trimmer shines, as it provides .080 line diameter bump feed and a die-cast gearbox. The cutting path varies between 14 and 16 inches, so you don't have to spend too much time on one spot.

This battery weed eater comes with a powered batter unit that packs quite a big punch. You get two separate battery variants; one that measures 2AH, and a 4AH option. The 2AH battery charges fully in half an hour, and it works for 45 minutes on a single charge. On the flip side, the 4AH option takes an hour to charge and can be used for 90 minutes.

Sadly though, you might need to get a lot of these attachments (batteries, chargers, and much more) separately. So, keep that in mind while budgeting.

Things We Liked

Comfortable handle

Battery variants make for more informed selections

Attachment-capable powerhead

Things We Didn't Like

The package doesn't include all the attachments you need

The Ryobi 18V One Plus Line Trimmer might not look like much, but don't let its small look and tiny structure fool you. It packs a heavy punch, and you have a lot to benefit from using it. 

With the Ryobi 18V, you get to enjoy a fully rotating head with this trimmer. So, for areas that are too thin won't be able to accommodate a parallel head rotation will easily present a quick solution. Also, you have the option to advance the Auto-Feed, which will help to ensure your safety.

User comfort is maximized thanks to the two-handle design of the trimmer, and the EasyEdge technology will help ensure that you can seamlessly make the switch from edging and trimming. The entire unit is also very light, so you won't experience any sort of discomfort as you trim and/or edge around your lawn.

As for downsides, you will come to find that this product is supplied as a bare unit. Attachments will have to be purchased separately, so keep that in mind when you're buying it.

Things We Liked

It's comfortable and lightweight

It provides seamless edger-to-trimmer conversions

The Auto-Feed is enhanced to ensure our safety

Things We Didn't Like

It's a bare unit, so you'll need to get its attachments separately

Another product to place a premium on aesthetic appeal and beauty, the Black & Decker GH3000R Electric String Trimmer/Edger provides versatility and a multifaceted scope, as it combines two devices into one body. 

Weighing just 8.6 pounds, this entire unit ensures that you can make the switch between the edger and trimmer functionalities with ease, thanks to a rotating head.

It's an electric string trimmer, so you won't need to spend extra cash on fuel or parts maintenance. However, a significant disadvantage with this is that there is a cord attached, which might limit your range of movement a little bit.

The Black & Decker GH3000R Electric String Trimmer/Edger is powered by a motor that runs on 12 Volts; enough power to get you through some of the toughest grassy areas in your home. There's the Auto-Fed feature included in this unit, and you will also like that you can easily hand-wind the spools to have them refilled.

As long as you can work yourself through the cord and prevent yourself from getting tangled between it, then you'll be more than fine with this electric weed trimmer unit.

Things We Liked

A double-purpose model

A lightweight build

It packs a lot of cutting power, even for an electric weed wacker

Things We Didn't Like

You should be careful with the corded design of this weed cutter

Editor's Rating:


Just as it is with a lot of options on here, versatility is one thing that the Remington Straight Shaft Trimmer/Edger gets right. 

The trimmer provides quick trimming and adequate coverage, thanks to a dual-line auto-release head that has a clearing path of 14 inches. With this, you will never have to spend so much time trimming one spot. The motor of the unit measures 5.5 amps, so you're also assured of enough power to back all of your trimming and edging activities.

The handle rotates full 180 degrees, and an edging wheel will also help to improve the efficiency and speed with which you trim your lawn.

The most prominent feature provided by this product, however, would have to be a telescoping shaft, which collapses easily for compact storage and adjusts accordingly to fit your height. Regardless of whether you're tall or not, this trimmer comes ready to be used by you.

Again, like a lot of electric trimmers, you will have a lot on your plate when dealing with the power cord. Still, though, that seems like a minor hurdle for most people.

Things We Liked

A rotating handle makes work much easier

The telescoping shaft boosts storage

The trimmer adjusts to your height accordingly

Things We Didn't Like

Cord placement is a bit of an issue

So, we're taking a break from the multifaceted tools and producing the list up with the Homelite Gas Powered Straight Shaft Trimmer, a solitary string trimmer that is definitely worth the name. 

This gas weed trimmer might be refurbished, but it has all of the functioning standards and features to make you believe that it's new. The clutched engine that comes with it will ensure that the trimmer starts easily, although a significant aspect where the product does come short is in its scope of work. With just a 0.080 line, it is only capable of handling light and medium-duty cutting jobs.

So, if you're looking for something to trim around strong grassy areas, then you might want to get something with more power.

This gas weed eater features an easy-loading bump weed eater string, which ensures that you can operate it conveniently. This, as well as the adjustable handle, will help enhance your comfort while running the gas trimmer.  

You also don't have to worry about featured accessories with this gas weed wacker, it features all of the original attachments, so it's at least a good bargain.

Things We Liked

Easy to start

The telescoping shaft boosts storage

The weed wacker string is also able to cover a considerable distance

There are no wires, so your movement is more comfortable

Things We Didn't Like

It's lagging when it comes to power
