String trimmers also come in handy when experiencing those areas of the farm or landscape which are difficult to reach, whether because the ground is uneven, or because of limited space makeing the perfect piece of equipment essential.

These devices, know better known as weed eaters or weed whackers. In essence, they are versatile and a useful tool to have on hand for any homeowner that we guarantee you will quickly become attached to and find many a job which becomes a lot easier because you have one.

Many areas of backyards are not suited for mowing, a weed trimmer can be invaluable.

What Exactly is a Weed Eater?

So what exactly does this tool comprise? In simple terms, it consists of a rotating motor on the end of a waist-high shaft. Attached to the motor is a nylon cord which have a very high-speed rotation forming an efficient cutting edge. The mechanics swing the head back and forth over the weeds or grass allowing the nylon cord blade to cut neatly. They are great for clearing weeds, some combo models don’t just deweed but also have an inverted conversion to very effective edge. Weed strimmers have been around for some time leading to many amazing solutions to expand the wackers capabilities further than ever, we have tried to offer a mix of all kinds of combinations.

Battery or Gas Powered

There are essentially three methods of powering your weedwhacker; electric, battery or gas / oil. We believe corded devices powered by electricity are no longer a practical option for many gardeners epecialy when there are so many new cordless options available. The wire is cumbersome, catches on things and makes working more difficult. For this reason we advance to cordless weed wacker models in our recommendations.

  • Corded models are the cheapest however the cost reflects its inconvenience.
  • The choice between gas or battery-powered really comes down to the type of job you look to do. Gas weed trimmers are more robust and have higher horsepower and can be running the longest between refills. Compared to most battery-powered models that need to be charged, however, some models provide a two lithium-ion battery pack increasing runtime.
  • Typically a gas weed eater weighs around 10-12 pounds which are heavier than their battery-powered cousins. They are more loud too and it may be wise to put on ear defenders when operating them for longer periods to protect your ears.
  • Battery-powered cordless weed eaters, although heavier than corded models are lighter, more maneuverable, and quiet than gas-powered equivalents.
  • When it comes to charging the battery-powered weed whackers it is a relatively inexpensive process, however, if you buy gas weedeaters you have to add off to the total prices of engine fuel  ( petrol, propane, or gasoline ) which is a lot more hassle and more expencive.
  • With a battery-operated model, a battery typically lasts around 30-40 minutes of use before requiring a recharge, more than enough to time to whack as much as you want in most backyards.

Ultimately your choice will come down to the purpose and kind of job you want the weeder for. A battery-powered unit can be easily grabbed and used for 10 minutes before being put back on charge. A gas unit will clearly require higher maintenance, however, if the job is a really big one a gas-powered trimmer is probably your go-to option.

A cordless weed trimmer is versatile and useful.


Please note that the battery for some of the battery-powered devices is not always included and requires a separate purchase. If you are on a budget then this needs confirming before you commit to buy as you will need to find a compatible battery before starting.


Weed eaters have nylon blades that operate at a very high rpm/hp and spin very fast. There is an obvious danger that anything coming into contact with the cutting edge will do some bad damage, including your skin. They do install a mini curved plastic safety shield that fences off and keeps most of the debris away but there is still a low probability of happening.

They also kick up a lot of debris around the cutting area which may get into your eyes and can also be quite noisy. As insurance consider getting some safety gear e.g safety goggles, ear defenders, and good sturdy gloves, and just generally take care. If you come across larger stems or branches maybe consider cutting them with a pole saw or chainsaw.

Bump or Automatic Feed

As the nylon cord cuts the grass and weeds the edges start to wear away so you need to replace it every soften to repair the cutter. Most devices feed the tool in one of two ways. Additional nylon cords can be threaded automatically, or loading by self-bumping the head of the trimmer against a flat surface, usually the floor.

Although an auto winding would appear at first to be a no-brainer, in reality, the automatic rewind is not perfect and tend to overload the tool resulting in more wastage and can end up having to restring. In contrast, the bump threading takes a bit longer but the response is more reliable and more efficient.


Most weedwhackers are not particularly heavy, but shoulder a backpack kit or straps are available for some models to help keep them operating effectively if you are doing commercial work or working for a longer period.

If you want your patio weedeater you may want to look at string trimmer extension accessories like steel wire brushes that brush away the tough weeds between your sidewalk tiles or where your home wall meets the floor. These small metal parts can be attached to the cutters increasing the projects you can do with your cutter.

Black and Decker LSTE523 Li-On String Trimmer

BLACK+DECKER LSTE525 20V MAX Lithium Easy Feed String Trimmer/Edger

Black and Decker are a very well-established manufacturer of a wide range of garden tools. They have a number of string trimmers, as well as reel mowers, leaf blower models, and edgers, but are in fact one of the most widely known weed eater brands. The orange and black LSTE523 is a great device that will manage most backyard trimming tasks with ease and is positioned at a good price point to make it affordable for almost every household.

It has an automatic wind line feeder activated at the push of a button, feeding into a 12-inch precision cutting head. 12 inches is pretty standard for most residential trimmers. It has a 3.0 Amp, 20V Lithium battery which does come with it which provides nice powerful clippers. The charge should last for anywhere between 30-40 minutes of use, which should be more than enough time to complete most domestic backyard strimmer tasks. If you are looking for a tool that handles much longer tasks then there are alternative models recommended next.

Should extra power be required for the thickest weeds, the trimmer also has two interchangeable speeds to enable such cuts to be made without hassle.

The head has a built-in wheel which allows the unit to be easily rotated via a handle on the shaft turning the trimmer into a neat little edging machine.

Finally, the height of the shaft can be adjusted to allow you to test their preference for a comfortable held led position dependent on what’s the shape and size of the user.

Things we like

  • Black Decker is a convertible trimmer and edger.
  • With a 20V Li-ion battery, get a prolonged cutting experience (30-40 minutes per charge).

  • The Easyfeed feature allows a simple method of extending the cutting line from a button on the handle.

Things we don’t like

Our Verdict

Most domestic users of weed eaters are looking for a balance between affordability and capability when buying tools. We believe the Black and Decker LSTE523 trimmer is a good quality tool that is well-built and easy to use. The automatic line feeder means there is no issue with trying to keep the cutting line efficient, the edger wheel and the handle on the shaft mean that it is easily and quickly converted into an edger. Finally, the tool is affordable and provides, in our opinion, great value for money. 


Black and Decker LST300 20V Lithium Trimmer Edger

BLACK+DECKER LST300 20V Lithium Trimmer Edger

The Black and Decker red LST300 is another model from the Black and Decker trimmer family. One difference to compare to our strongest product the LSTE523 essentially is it does not incorporate a built-in wheel to enable an easier walk and trim. However, the price point for the snippers is cheap and as a result it represents an reasonable balance between capability and price. Although being budget shears it can still pull off all the features you might expect from a good quality string trimmer.

It incorporates Black and Deckers Easyfeed automatic line feed spooling, operated from a button on the handle. The motor is powerful and capable of easily dealing with most backyard cutting jobs, whether it be trimming the edge of the lawn or weed whacking this cleaner can wrap is head around and remove any unwanted flower bedside growth. A handle on the shaft allows the head to be rotated to turn it into an edger and doubles up as a height adjustment control.

The rechargeable battery comes with the unit and can be expected to run for between 20-25 minutes dealing with most tasks while doing so.

The weight of the weed eater is 7 lbs making it slightly heavier than equivalent models and this may well be a factor for some to consider as extended use could become difficult.

Things we like

  • A good quality trimmer positioned at the value end of the price spectrum.
  • You can use it as both an edger and a trimmer.
  • 20-25 minute run time for each battery charge.

Things we don’t like

  • Heavier than many rival models which can cause problems for some people although compared to a gas-powered model it is still quite light.
  • Not really suitable for heavier clearance work.

Our Verdict

The LST300 is a well-made budget string trimmer that is more than capable of dealing with most domestic backyard weed clearance tasks. It is priced to be affordable for almost everyone and it is this fact coupled with its quality build, strong manufacturer’s warranty, and good brand name that ensures this model makes it onto our list of favorite weed eaters.


DeWALT DCST990H1 40V XR String Trimmer

DEWALT DCST970B Flexvolt 60V Max String Trimmer

DeWalt is synonymous with high-quality professional tools, an expert both for building tasks and in the garden. High mechanical and style quality is assured. This model delivers the biggest sizes of cutting swathes at 15 inches of all our ranked products, it’s rating is near the higher end of domestic trimmers capable of easily dealing with domestic weed control.

Unlike the single Black and Decker models, the cutting head has a double line. The multi-line system makes it able to weedeater tougher cutting tasks both comfortably and with simplicity. The feed type is a bump spring feed which we found worked easily and reliably.

Being essentially a professional tool this is an industrial-grade trimmer heavier than many domestic-only devices, weighing in at just shy of 14 lbs. If it were me, I wouldn’t use it free-held due to the weight, my preference would be to buy a strap or harness to make it more portable and properly handled. The additional weight does make its use handheld as an edger more difficult, although it is still more than capable of dealing with most edging tasks like flower beds or fence edges with the right technique.

The motor is variable speed controlled by a pressure trigger behind the handle making it easily adapted to different outdoor cutting conditions from tall hedges along fields to an overgrown parkside bush.

Things we like

  • Dewalt DCST990H1 is a heavy-duty, powerful trimmer suitable for all cutting tasks.
  • Large 15-inch cutting swathe.
  • Allows the alternate use of 0.080 and 0.095 nylon cutting lines.
  • Comes with a brushless motor that ensures maximum usage of battery life and more extended service of the motor.
  • Comes with a fast variable speed trigger that allows users to change between more power and prolonged use (Hi/Lo).

Things we don’t like

  • Has a 14 lbs weight which can be tiring in the long run during prolonged heavy-duty jobs.
  • Lacks a shoulder harness to help with fatigue that might follow from prolonged usage.
  • Though it can be used for edging, this device is not for edging.
  • String change can be a bit fiddly.
  • High price point.

Our Verdict

There is no doubt that the DeWalt DCST990H1 cordless string trimmer is positioned at the highest end of the pricing spectrum. This is due to the fact that this is a powerful, well-built device capable of dealing with all types of cutting tasks in even the most difficult of conditions. In summary, if you need an efficient tool capable of cutting a larger than the regular swathe for extended periods then this is the trimmer for you.


Greenworks 21362 14-Inch 40V Cordless String Trimmer

Greenworks 14-Inch 40V Cordless String Trimmer

The GreenWorks 21362 trimmer is a quality well-built tool more than capable of dealing with almost any trimming task you could throw at it. It has a high cutting swathe at 14 inches which together with its thicker 0.08 dual cutting line can deal very efficiently with large-scale landscaping clearance.

The motor is brushless making it more reliable and quieter and it is also powerful. With some trimmer models you sacrifice some power when you choose to go cordless. Not with this Green works model which deals with all cutting tasks easily.

The line feed is the bump-stringing type.

All of that would normally be enough to give it a recommendation, but the GreenWorks trimmer also offers the capability for gas attachments from other brands to be used with the motor, attachments such as cyclone blowers, cultivator heads, edging heads, hedge trimmers and a pole saw. This makes is an extremely versatile garden tool that is difficult for any serious gardener to overlook.

Things we like

  • It comes with an attachment feature which means that users of this device can utilize most of their gas trimmer add -ons on this instrument.
  • A Brushless motor provides a longer-lasting battery life and a more reliable motor.
  • It has a 14” string dual line cutting swathe for a wider cut.
  • The battery provides as much as 1 hour of continuous use.

Things we don’t like

  • The weight clocks in at 15 lbs so a shoulder harness is recommended.

Our Verdict

The GreenWorks 14-inch cordless string trimmer is an excellent trimmer, capable of handling all domestic trimming tasks easily. It is more than that, however, with the capability and builds quality required for heavy-duty clearance tasks too. But the attachment feature, the ability to swap out the trimmer and fit other cutting heads really sets this trimmer apart from other models and makes it a definite buy recommendation.

In fact, from all our cordless weed eater reviews, this GreenWorks 14-inch model would be our Best Buy pick.
