Things to Consider When Looking for a Weed Eater

You’ve mowed the lawn, carefully weeded your flower beds… now what? It’s time to tidy up around the edges. While you can do this the old-fashioned way by getting down on your hands and knees, it’s much easier to get the job done with a weed eater. 

However, knowing what to look for can be a bit daunting. Here are the top considerations you need to make when shopping for your next (or first!) weed eater.

What is a Weed Eater?

Although weed eaters are essentially the same thing as electric trimmers, there are some minute differences between the two. Weed Eater is technically a brand name of the original kinds of string trimmers. Today, the phrase Weed Eater is used interchangeably with the word “trimmer,” just like people call tissues Kleenex even though there are multiple brands. 

With a weed eater, you can perform a variety of tasks. You can get rid of thorny vines or brush, or you can use the tool as an edger to trim weeds along pathways and driveways. You can also trim small bushes and shrubs or even mulch leaves with most types of weed eaters. 

The 3 Types of Weed Eaters

Broken down a bit further, weed eaters can be characterized as electric trimmers, gas trimmers, and battery-powered trimmers. 

  • Electric powered weed trimmers are preferred by homeowners because as long as you have power, you can start this kind of device. You may be limited by the length of your electric cord, meaning it might not be ideal for a massive lawn, but keep in mind that you can easily add an extension cord.
  • Gas trimmers have more powerful motors but need a lot of maintenance. They can be difficult to start and quite noisy to boot, making them impractical for people who live in crowded areas. 
  • Battery-powered trimmers are portable and quiet, but usually can’t perform for more than an hour or so.

In our review, we’ve included some of the best corded (electric) and cordless (battery-powered) weed eaters you can find. Neither require gas and instead are powered by electricity, with battery-powered weed eaters simply needing to be recharged from time to time instead of being connected to your power outlet at all times while trimming.

Cords vs Weight

You need to think about your physical limitations as you are selecting the best weed eater for your needs.

The lightest weed eaters are the corded ones since they don’t have a gas tank, battery, or metal pistons. Battery-powered electric weed eaters tend to weigh a little more than corded ones because of the battery. Gas-powered weed wackers will be the heaviest, weighing ten or more pounds in most cases.

Of course, the tradeoff when buying a light, corded weed eater is mobility. You’ll be limited by the length of your cord, which will also get tangled and caught on things. Still, you won’t need any fuel or recharging, so you can keep it running until it overheats.

Noise Level

Gas-powered weed eaters are the noisiest because they have powerful motors that are designed to tackle heavier material. If you don’t have large tasks to tackle, a quieter battery-powered or electric weed eater should get the job done just fine. 


Gasoline trimmers tend to be on the more expensive side while electric or battery powered options cost much less. Consider the size of your yard before deciding on your budget, but keep in mind that weed eaters can cost anywhere from $50 to $200 (or more for all the bells and whistles).

Environmental Impact

If you’re looking for a machine that won’t further burden the environment, consider either a corded or cordless electric or battery-powered trimmer. Because these don’t produce any emissions, they are easier on the environment. Many states have incentives in place to encourage you to purchase a corded or battery-powered weed eater, too, making it an even smarter choice for your conscience – as well as your wallet.

How to Choose The Best Electric String Trimmer for Your Garden

Now that you’ve settled on an electric trimmer versus a gas-powered machine, it’s time to think about the features that are important to have in an electric weed eater. Here are the top concerns you should think about before making your purchase of a rechargeable weed eater or an electric grass trimmer.


Not everybody who uses a weed eater is going to be the same height; therefore, it’s important to consider how extendable your weed eater is. The best electric grass trimmers will be able to extend out, with some moving out several feet or more. Remember that this kind of flexibility does come with a tradeoff: the further you extend it, the more you throw off its balance.


The design of an electric trimmer will play an important role in your final purchase decision. All weed eaters will have a handhold at the top with a second handle midway down the shaft of the unit to provide balance and stability. The motor and rotor will be responsible for spinning the cord or string from the bottom of the shaft. 

Most weed eaters are made out of materials like plastic, aluminum, and in rare cases, steel. You won’t find much variation between machines in this regard. However, a well-designed electric trimmer will have good grips and handle positioning that gives you the angle necessary to avoid awkward bending or maneuvering. 

Each weed eater will have a different kind of cutting string or cord, too. The string is very light but it is constantly worn away as the result of the repetitive cutting behavior. Usually, electric or battery-powered weed eaters will have round trimmer lines, which are designed to trim grass edges around a lawn and not to deal with heavy brush. 

This string, as with other types of cutting string,  is housed within the head of the unit and will have several different options for how you feed out more line. If you’re shopping for a more heavy-duty (usually gas-powered) weed eater, you might find cutting strings that are multi sided, twisted, or serrated – but again, these are less common in electric or battery powered weed eaters, as the unit typically does not have enough power to operate the heavier cutting lines.

Think carefully about the head of the weed eater. You can purchase a weed eater that has a bump feed, fixed feed, or automatic feed. 

A bump feed is one that allows you to call for more line any time you need it. All you have to do is lightly bump the end of your weed eater against a firm, flat surface. The bumping motion will allow the head to feed out more line. You can bump as many times as you want. 

An automatic feed, on the other hand, lets out string on a preset ratio. You won’t have to stop and bump the head to get more line, and you won’t have to replace the string as it gets too short. However, some autofeeders aren’t as efficient as others, with some models feeding out too much (and some too little) line.

Finally, a fixed feed weed eater will eliminate the need to bump the head for more string. It also rules out the possibility of the auto feeder releasing too much string. However, a weed eater with a fixed line will require you to stop working if the string wears down so that you can replace it with a new feed.

You will also have a shield encasing the cutting portion of the weed eater. This shield will help prevent debris like grass cuttings, weeds, or sticks from hitting you in the face. Usually, the shield is made out of plastic, but some weed eaters will have unique options for how their shields are positioned and constructed.


Most weed eaters come with robust warranties, with a majority covering you for one to three years. Some offer lifetime warranties. 

Remember, however, that a warranty should not be the primary reason you purchase a specific electric weed trimmer. Warranties can be tough to claim on, and companies will often try to prove that you mishandled the device and that was what caused the damage. 

Therefore, it’s important to read up on the specific coverage of the warranty program before you make your purchase.


Electric weed eaters are useful tools that should be considered as an alternative to gas or powered weed eaters. They are easy to use and tend to be much lighter to operate. Plus, they are environmentally-friendly.

If you’re ready to take your lawn care to the next level, consider investing in one of these electric weed eaters today.

Electric Weed Eater FAQs

Where Can I Buy a Weed Eater?

There are well over fifty companies that specialize in weed eaters and string trimmers. You can purchase a weed eater from any company where you normally purchase lawn care equipment or from online retailers like Amazon.

What are some safety tips for using an electric weed eater?

Using an electric weed eater is not dangerous, but there are some easy-to-follow safety tips that you can incorporate to make operation a bit safer. For example, avoid bumping the head of the trimmer too hard against the ground, and try to hold it level when trimming near obstructions. 

You should also wear proper eye protection and footwear, as you never know when an object or debris will fly back and hit you. You should avoid using a weed eater in tight quarters and avoid putting your hand anywhere near the trimmer head while in operation. Only use high-quality, safety-rated extension cords, and try not to overwork your weed eater’s motor by asking it to do more than it is capable of.

What Causes a Trimmer Line to Break?

Unfortunately, your trimmer line will break from time to time. This is not a catastrophic event, as you can easily replace the line on your electric weed eater. However, there are steps you can take to prevent the likelihood of this occurring. 

The most common causes for trimmer line breaks are faulty parts, improper storage, and contact with a foreign object. Pay attention while you are operating your machine so that you can keep an eye out for what is coming. Avoid putting the head of your weed trimmer into areas where there is loose debris. 

If something happens to break, try not to use cheap or knock-off replacement parts. You don’t need to invest thousands of dollars into fixing your equipment, but you should only use approved parts when fixing your weed eater. The same rule applies for storing your weed eater. If a weed eater is not stored properly, it can lead to corrosion and line breakage.

How Should I Maintain My Electric Weed Eater?

Luckily, electric trimmers don’t require as much regular maintenance as gas trimmers. However, there are simple steps you can take every day to make your electric weed eater last much longer. Try to only use the appropriate gauge of extension cord to power your device- this information will be available in the manufacturer’s pamphlet. 

In addition, you should check your trimmer regularly for any damages. Clean off the air intake slots before each use to prevent the unit from overheating, and never immerse the trimmer in water or clean it with high-pressure water, as this can damage the internal components. 

Store your trimmer indoors and out of the elements and you’ll reduce the likelihood that you will need to invest in expensive repairs (or a new trimmer) later on down the road.
