PROS

A single charge of the battery will offer you up to half an hour of runtime.

CONS

The release button on the battery may jam up from time to time.

OUR VERDICT

Greenworks 12-Inch 40V Cordless String Trimmer is a great overall model but the kind of power it offers will prove to be a bit of an overkill if you're simply looking for a string trimmer. But if you plan on investing in a few other gardening and landscaping tools, you should definitely give this product a try.

Husqvarna 128LD

It All Begins With a Start Button

Generally speaking, string trimmers tend to be relatively simple devices that serve a singular purpose without a variety of additional features and functions. Well, that's not exactly the case with the Husqvarna 128LD. Of course, just like any other similar product, it'll offer you the ability to cut the unwanted weeds and grass, but the model also provides so much more on top of that.

Since it all begins with a start button, that is going to be the first thing we will highlight. Now, what we have here is a gas-powered device, and those usually require some time to get started. Fortunately enough, that isn't the case with the Husqvarna 128LD. Accurately dubbed as a Smart Start® function, the technology essentially sets in motion the 28cc engine and the starter, both of which are designed to start as quickly as possible, all while requiring a minimal amount of effort. But that's not nearly the only thing it offers in terms of operation inception, so to say. The air purge also makes a solid contribution by removing air from the carburetor and fueling the system, further simplifying the starting point. Finally, to get this particular subject out of the way, we would be remiss not to mention the auto return stop switch that automatically resets the string trimmer to an "on" position after you turn the device off, making it ready to go anytime you need it.

Review of Husqvarna 128LD Straight Shaft Detachable String Trimmer

Turn It Into Anything

When it comes to the actual performance, the aforementioned 28cc engine offers enough firepower to handle just about any outdoor work. From trimming some of the more stubborn hedges to clearing away excess branches, the T25 semi-automatic trimmer head that comes with the package will be able to deal with all of that. And if you happen to run into the sort of obstacle that'll prove to be a bit too much for the latter, just take the trimmer head off and insert virtually any other professional grade attachment via the "click-on" convenience. The only thing that remains constant is the base engine unit that will be able to carry on regardless whether you feel like using the tool as a string trimmer or a hedge trimmer, brushcutter, pole saw, or even an edger.

Of course, with great versatility comes great responsibility in terms of ensuring a comfortable and convenient operation. And what better way to make that comfort happen than to reduce the size of the tool? With just 40 inches in length, the model will offer you the freedom required to deliver those finishing touches to your lawn. And once you're done with it, the detachable shaft will allow you to transport the tool and store it with effortless ease.

Well, that's about everything that is worth mentioning. If you don't mind the limitations that come with the cord and the gas tank, what we have here is easily the best string trimmer for the kind of customers who aren't just looking for a way to trim the lawn but for a versatile, multifunctional tool that will allow them to finish any lawn or landscaping job.

What customers say about this product

Features

The detachable shaft is a revelation. You get this, and over time add the other attachments, and you can take on just about anything if your clearing your property.

Power

With the first tank of fuel I could tell it needed a break in cycle. After that first tank, it runs strong, smooth and quiet for what it is!

Key Specs

My favorite feature is the straight shaft that allows easy rotation (click and turn) of the head for flat cutting or right angle edging.

Size & Weight

Weight and balance are good.
 

DEWALT DCST920P1

Operation

This string trimmer runs on a 20V 5.0Ah Lithium-ion battery which ensures up to 45 minutes of non-stop operation. What this literally means is it poses minimum limitations on you and is perfect for those who have a fairly large garden or lawn that requires trimming. One other advantage to this model being a battery-powered tool is that it entails no regular expenses which are associated with gas trimmers such as buying gas and oil. Furthermore, since it has an electric model, it doesn't emit any harmful emissions which makes it an ideal solution for self-conscious users that worry about the health of our planet. Finally, its cordless design means no annoying cords and cables that always get in the way and impede the operation of the tool.

Review of DEWALT DCST920P1 Ah Lithium Ion XR Brushless String Trimmer

Usability

DEWALT string trimmer has a convenient handle. This garden tool has 2 available speed settings for trimming different grass - from small and thin to quite tall and thick. The common 0.08-inch cutting line is usually made of nylon and that's why it wears off, making trimming nearly inefficient. DEWALT engineers have come up with an idea of a bump feed system to solve this issue. It is incredibly simple: you just need to gently bump the trimmer on the ground to release some more cutting line. However, the line shouldn't be extended beyond 13 inches. DEWALT string trimmer will help you trim grass even in the most hard-to-reach areas of your yard or garden. But this tool isn't all-powerful - you should avoid trees and shrubs; this weed eater is for grass after all.

DEWALT DCST920P1 Ah Lithium Ion XR Brushless String Trimmer in the use

Size and Weight

This string trimmer is rather big - the total length is 67.8 inches and, what is peculiar, you can't adjust the length. It makes DEWALT weed eater rather safe since the cutting line is far from a user's body. The overall weight of this tool is 8.5 lbs. It is not strange as the unit is made mostly of aluminum and plastic. In fact, the tool is rather lightweight and any person can use it; no need to be a muscular bodybuilder.

Black & Decker LST136W

Operation

This is an electric cordless weed whacker produced by the well-known American brand, Black and Decker. This model has a powerful 40V Li-ion battery that you can remove and charge when it is necessary - the charging takes around 1 hour though you can charge it longer for the best runtime. The electric motor is good - the trimming string rotates at a speed of 8500 RPM and easily cuts grass, thick weeds, and small shrubs. The motor is quiet (since it is electric) and easy-to-operate.

Review of Black & Decker LST136W 40V Max Lithium String Trimmer

Usability

The advantage of this electric cordless string trimmer is the adjustable shaft length - you can make it a bit shorter or use a default (full) length. This is particularly good for short people who feel uncomfortable using a too long weed whacker. Also, there is an LED indication of battery charge and you can control the rotation speed - either more power and smaller runtime or vice versa. Also, the unit easily converts into an edger and cuts weeds along the lanes.

Black & Decker LST136W 40V Max Lithium String Trimmer in the use

Size and Weight

The overall length of the string trimmer is 43.9 inches, so really tall people might feel somewhat uncomfortable using this tool. However, for people of small or medium height, this grass trimmer is nice enough. Also, it is quite lightweight thanks to a small electric motor - just 6.8 lbs. If you need a high-tech money-saving yet efficient grass trimmer - Black and Decker is a truly excellent pick.

What customers say about this product

Size & Weight

Light weight - PERFECT for even a small framed woman to handle.

Features

Adjusting the intensity of the 'whacking' is simple, just a twist of the dial. Easy for grass (I mean the thick stuff that hasn't seen a mower in two years) and brush.

Power

Battery fully charges in around an hour and from what I understand you can just leave it on the charger until needed.

Key Specs

The shaft retracts into itself for a smaller footprint.
 

WORX WG163

Release the String

The WORX WG163 GT 3.0 is a powerhouse of features that will be able to attract just about any customer who isn't interested in your average, run-of-the-mill product. But despite the number of interesting features, there's one that stands out the most, appropriately named the Command Feed. In layman's terms, the innovative solution offers a spool system that instantly releases the string (also known as the line) the moment you start to run short on the latter. Not only does it make the entire process that much more effective but the solution also helps in terms of extending the service life of the cordless string trimmer.

Speaking of releases, there's also the quick-release lever that will provide the user with the opportunity to quickly adjust the height of the 90-degree tilting shaft. As you would imagine, both of these components will make reaching the seemingly inaccessible areas as simple of a task as it could possibly be. And since we aren't talking about some cheap product here, an ergonomic handle is also there, offering enough comfort to work around those areas without putting too much of a strain on your hands. Though the weed trimmer features about 47 inches in length, the whole thing weighs less than 6 pounds, meaning that we're dealing with one of the lightest options on the market.

Review of WORX WG163 GT 3.0 20V Cordless Grass Trimmer

An Edger as Well

Now, before mentioning a few other features, we would like to point out the fact that the WORX WG163 GT 3.0 isn't just a string trimmer. Without the help of any additional tools, the model turns into an edger in a matter of seconds, offering you the ability to form distinct boundaries between the lawn and other elements of your yard. The dual-positioned in-line wheels that the manufacturers made sure to implement into their product will make the process of edging an absolute cakewalk.

Other than that, the model also features 100% automatic single-line feed, meaning that you won't have to deal with the usual issue of bumping to extend the line. Whether you're trimming, edging, or mowing, the handle offers 7 locking adjustments, all of which provide you with nothing but comfort by adapting to the landscape.

Naturally, you'd prefer to trim the grass in your lawn without damaging the plants and vegetables, so the people at Worx also didn't forget to add an adjustable spacer guard. Aside from protecting everything but grass from the wrath of this machine, the component works overtime by acting as the edger guide. And even though a single 20V MaxLithium battery offers enough power to extend the runtime, the second one that comes with the package is not going to hurt either. When one of them runs out of steam, simply put another one in and keep on trimming.

In conclusion, we could probably go as far as to call this model the best weed eater on the market since it delivers nothing but new levels of power, precision, and function. Plus, the remarkable number of features will be able to accommodate even the most particular customers.

GreenWorks 2101602

One Battery to Rule Them All

Right off the bat, the Greenworks 12-Inch 40V Cordless String Trimmer is probably not the best option for people who are looking strictly for a string trimmer. It isn't that the model won't be able to cut it (speaking both literally and figuratively), it's that the 40V battery system will prove to be a bit of an overkill, with 2 times the power of your standard trimmer battery. No, what makes this battery system special is that both its power and the design will be able to accommodate up to 25 different tools from the very same company, so you will be able to save a long of money in the long run if you intend on buying a few landscaping or gardening tools a bit further down the road.

With so much power under the hood, it goes without saying that what we have here isn't the lightest option on the market. Though given the battery's capabilities and 65 inches in length, the fact that the whole thing weighs less than 10 pounds is nothing short of impressive. But what the cordless string trimmer in general and the battery in particular lacks in elegance, if you will, it more than makes up for that with power. A single charge of the battery will offer you up to half an hour of runtime, which is twice more than what your standard trimmer is capable of delivering. Besides, it takes the battery no more than an hour to recharge, so you won't be wasting too much time on that either.

Review of GreenWorks 2101602 12-Inch 40V Cordless String Trimmer, 2.0 AH Battery Included

Variable Trigger Speed

As for some of the more technical characteristics, we would like to direct your attention towards a couple of those that we believe to be the most interesting or important. First things first, we're dealing with a dual-line spool system. A dual-line head trims a lot faster than the single-line models since it cuts twice as much weed with each revolution. The line feed is automatic, meaning that it only releases more line (string) when it is necessary. That way, there's less of a chance that you will break your weed trimmer by bumping it into the ground. Plus, it will improve your performance just as well as it'll prolong the service life of the product.

Finally, we would be remiss not to mention the variable trigger speed. Depending on the cutting conditions, it provides a different level of power, offering you more speed when you deal with thicker grass or slowing down in order to extend the battery life when that additional speed is not necessary. Add to that the 12-inch cutting path and rest assured knowing that you'll be able to trim your entire lawn in no time at all.

To rephrase our earlier point, the Greenworks 12-Inch 40V Cordless String Trimmer is a great overall model but the kind of power it offers will prove to be a bit of an overkill if you're simply looking for a string trimmer. But if you plan on investing in a few other gardening and landscaping tools, you should definitely give this trimmer a try.

What Is a String Trimmer?

A string trimmer has many names - this tool is also called a weed whacker, weed eater, grass trimmer, and so on. As the very name indicates, this tool is used to cut grass and weeds, just like a lawnmower, but unlike them, weed whackers allow you to handle steep and hard-to-reach places. Also, they are much cheaper than conventional lawnmowers and require less storage space. A weed eater has a long shaft with a cutting head at the end. Of course, there is an engine, a handle, and a shoulder strap to carry a string trimmer.

While you're shopping for garden equipment we'd like to offer you to take a look at other tools that may come in handy in various situations such as gas chainsaws, edgers, and lawn mowers.

Best String Trimmers

What Features to Compare

There are many string trimmer reviews on the Internet but making the right choice is still a major problem for a common customer. Some reviews provide too much unnecessary information and useless details. That is why we have done our best to make our weed eater review clear and informative. We have compared 5 best string trimmers by the features that present the maximal importance for customers.

First of all, you need to decide on the operation. Weed eaters can have different engines - there are gas-powered weed eaters which yield plenty of power but require the use of gas and oil and there are electric string trimmers that won't be as strong but will provide you with more flexibility and safety during application. The latter can further be divided into corded models that work from an outlet and cordless ones powered by batteries. If you have a small backyard you may benefit from buying a corded string trimmer, should it come with a long enough cord, or you may opt for a cordless grass trimmer if what you need is maximum flexibility. The advantage to cordless trimmers is that many of them come with the kind of batteries that can be used on other tools produced by the same manufacturer, making them a sensible solution for those who already own some collection of garden tools. The power yield of an electric string trimmer varies in the range of 175 and 1400 Watts and the tool typically requires around 10-15 min breaks between working cycles to prevent its motor from overheating.

The next feature to consider it the usability - a grass trimmer should feel comfortable in your hands so that you don't get tired too quickly while running it. To select a suitable model, make sure to consider what convenience features it offers. Many string trimmers feature an adjustable handle and a strap allowing the user to hold it comfortably. Some of them may also have an adjustable shaft which will enable you to change its working height depending on the type of cutting task you've got at hand. Many manufacturers supply their tools with additional attachments and accessories that expand functionality of the tools making them suitable for other jobs besides cutting grass. All of these are those extras that contribute to the usability of a grass trimmer and make the choice less tricky.

Last but not least, you should consider the size and the weight of a weed whacker. Unless you're a bodybuilder looking to grow your arm muscles, it's best to go for a smaller and more lightweight model. Also, you should consider the length of the shaft; despite many of them can be adjusted, it's still important to learn the original working height of the tool in order to estimate how much adjustment can be done.
