Best Electric Grass Trimmers

Summertime brings all of the flowers and green grass back to each neighborhood. When it comes to maintaining your lawn and ensuring its health, there are several critical tools that you will need. One of those tools is a grass trimmer (also known as a weed eater, weed-whacker, and weed-whipper, among other names) as you can only get so close to certain objects when using your lawnmower. Without the use of this tool, there is virtually no way to make your lawn look as terrific as it can be. But, these tools can either be gas-powered or use the power of electricity.

Below we have listed the top ten best electric grass trimmers in the market today including detailed criteria for each trimmer to help you decide which one suits you best. Truth be told there are pros and cons to both gas-powered and electrically-powered trimmers,  and here we look only at electric models.  Do your homework to find out what’s best for you.  If you’re starting your search here with electric trimmers, some advice we can give you ahead of your analysis is to look for higher voltage batteries (for cordless models) and for cord locks to prevent the extension cord from unplugging (for corded units).

10 Best Electric Grass Trimmers

EGO Power+

In the world of electric power tools, Ego Power+ just seems to be one step ahead of the competition. It does not hurt that their weed eater is equipped with a monstrous 56-volt battery.
Expand to see more
Design Type
This is a cordless model and it does not feature any old battery. Instead, Ego Power+ equips their weed eater with an industry-leading 56-volt lithium-ion battery.

Performance
In addition to the 56-volt battery, this is designed with a brushless motor for increased efficiency and longevity. Also, the head is 15 inches and cuts a wide path.

Design Features
When fully extended, the aluminum shaft measures 49 inches in length. Also, the bump feed head is integrated to make it easier for string to be drawn.

Overall Handling
Though some users have claimed this is relatively easy to handle, one buyer noted that the balance could use improvement as it can feel awkward as a result.

Versatility
Because this has no length guide, it can actually be difficult to utilize it as an edger. If you are skilled enough, though, it certainly could be.

Overall
The sheer combination of the battery, motor and head of this top model speaks wonders for the overall quality of it. Although, the balancing issues are a bit of a downer.
Pros

Features a 56-volt battery

Backed by a five-year warranty

Delivers the performance of gas

Cons

There are balancing issues

Makita XRU02Z

Makita may be a brand that you have never heard of but after you witness their string trimmer that is sure to change. Of course, do be aware that this model does not include the battery required for operation.
Expand to see more
Design Type
Makita claims that their 18-volt battery, which is a bit of a drop off when compared to the previous models, can last up to 45 minutes on a single charge. However, the battery is sold separately.

Performance
Admittedly, this is not going to spin fast enough to handle anything more than lawn edging and everyday trimming. Still, the motor delivers 7800 revolutions per minute.

Design Features
Thanks to the telescoping shaft, you can adjust the length of this system from 48.5 inches to 56.5 inches. Also, the easy-loading bump head adds user convenience.

Overall Handling
Though this may not possess the power some users crave, the balance and overall handling are superb. Plus, it is ergonomically designed for even more comfort.

Versatility
Thanks to the compact size of the head and the fact that it can be adjusted in five different positions, it can be used for precise edging.

Overall
While Makita should probably simply include their battery with their trimmer, it is hard to argue with the results as a whole. Of course, it may not be ideal for larger lawns.
Pros

Has a 180-degree adjustable head

There is a battery capacity warning system

Both light and ergonomic

Cons

Not powerful enough for heavy-duty use

Black+Decker LSTE523

Boy, that did not take long. Even though this next model from Black+Decker sports only half the voltage of their other unit, it still features their PowerDrive transmission to increase the torque.
Expand to see more
Design Type
As opposed to the previous model, you do actually receive a battery with this unit. Its maximum voltage output is 20 volts, which is not as high as others on this list.

Performance
Once again, Black+Decker designed their weed eater with their PowerDrive transmission. On top of this, the head measures 12 inches.

Design Features
Unfortunately, the EasyFeed system of this unit is more of a hassle than it was intended to be. As users have reported, there can be too much line that gets released.

Overall Handling
Finding the perfect grip and fit should not be much of a hassle here. This is because of the equipped micro texture grip handle and adjustable height.

Versatility
Even if you want to use this tool for edging, it can be converted very easily to do so. As such, you can then use it alongside sidewalks, borders, flower beds, etc.

Overall
In spite of the fact that the EasyFeed system could have been engineered with fewer issues, this model still remains the highest of recommendations.
Pros

Designed with two-speed control

Can easily convert to an edger

Very light and easy to handle

Cons

The EasyFeed system is flawed

Black+Decker MTC220

Black+Decker MTC220
Talk about unique, Black+Decker went all out here. Instead of merely investing in individual tools, why not just get three in one? With this unit, you get a trimmer, mower, and edger.
Expand to see more
Design Type
Black+Decker actually offers both corded and cordless versions of their 3-in-1 system. If you buy the cordless version, you will receive two 20-volt lithium-ion batteries.

Performance
For the purposes of this guide, let’s assess the performance of the actual weed eater. With a 12-inch head and a gear-driven transmission, it should not bog down unless the grass is too thick.

Design Features
As with most other designs on this list, this is another weed-whacker that is designed with an auto feed system. Due to this, the need for bumping the head is gone.

Overall Handling
To improve the overall comfort, the lightweight and ergonomic design of the shaft has adjustable hand positions.

Versatility
It does not get more versatile than this. With three tools in one system, you can mow your lawn, trim around the edges, and also perform some edging.

Overall
It has not been mentioned yet but due to the size of this mower, it really is only ideal for tiny-sized lawns. As for the two-in-one edger/weed-whacker, though, it is a hit.
Pros

It is a 3-in-1 system

Offers ideal handling and comfort

Has a small footprint design

Cons

Can’t be considered a suitable option for anything more than small lawns

Greenworks 21212

Greenworks 21212
For such an inexpensive model, it is quite surprising how powerful this next unit is. Then again, it is not a flawless product so do not go in expecting perfection.
Expand to see more
Design Type
One of the issues with corded units is that the extension cord can accidentally get unplugged. Yet, with a cord lock integrated, Greenworks has minimized this issue.

Performance
The combination of the 13-inch head and the four-amp motor powers this system. While this is not the most powerful unit out there, it will be optimal for the right tasks.

Design Features
The good news is the adjustable telescoping shaft is a fantastic feature. Yet, the bad news is the auto feed head has received criticism for its inconsistency.

Overall Handling
As one consumer pointed out, the weight distribution here could use improvements. Then again, the total weight of seven pounds is certainly not bad.

Versatility
To allow for edging, the shaft on this unit can easily be rotated. When rotated, you can easily perform precise edging.

Overall
At the end of the day, you really can’t go wrong with Greenworks. In spite of the slight issues that are present, there is a reason their products sell so well.
Pros

The handle can be adjusted

Comes with extra spool

The head will rotate to facilitate edging

Cons

The spool cover has been prone to breaking

The feeding system is a bit inconsistent

Black+Decker LCC140

Black+Decker LCC140
Get ready to see Black+Decker make a few appearances on this list. They have a knack for producing high-quality, affordable tools and their LCC140 weed-whipper is one of them.
Expand to see more
Design Type
While this is not quite the 56-volt battery that was just documented, Black+Decker does include their 40-volt battery with your purchase. But, do note that some buyers have experienced issues with it.

Performance
What is nice about this unit is that the 13-inch head makes cutting faster. Meanwhile, the PowerDrive transmission delivers the cutting power that buyers crave.

Design Features
First of all, Black+Decker equipped their model with an automatic feed spool system to ensure the user does not need to bump the head. Also, the PowerCommand system allows you to choose different speeds.

Overall Handling
In addition to the fact that the weight is not too much of an issue, this is engineered with a soft grip handle which will improve the comfortability over longer uses.

Versatility
On top of the fact that this system can be converted to an edger in mere seconds, you also receive a sweeper with your purchase which can blow up to 120 miles per hour.

Overall
Despite some reported battery concerns, the LCC140 weed-whacker is one of the best in the business. Not the least of which is its superb combination of performance and handling.
Pros

You can choose variable speeds

Also comes with a 120 miles per hour sweeper

Designed with an automatic feed spool system

Cons

Some buyers have had issues with the battery

Toro 51480 Corded

Toro 51480 Corded
Now, it is time to show some love for the corded units out there. In specific, this weed eater from Toro which sports a very impressive 14-inch cutting head to improve efficiency on the job site.
Expand to see more
Design Type
Again, this is a corded unit. What this means is that it does not run via a battery and, instead, needs to be connected via an extension cord to an appropriate electrical source (such as an outdoor receptacle).

Performance
The combination of the 14-inch head and the powerful five-amp motor is able to deliver an optimal performance. For weeds and thick grass, it should rip right through it.

Design Features
To accommodate a wide range of users, this is designed with a telescoping shaft and adjustable handle. Also, this system works with an auto feed trim line.

Overall Handling
This system as a whole is lightweight and well-balanced. In addition to this, the integrated assist handle adds to the balance and the comfort.

Versatility
With the simple push of a button, this bad boy can convert into an edger with its integrated wheel. Then, once you push the same button again, it can be used as a weed-whacker.

Overall
The adjustability and versatility of this unit alone make it stand out. If you can deal with the fact that you need to carry a cord around with you, you will get your money’s worth.
Pros

Has an extra-wide 14-inch head

Engineered with a telescoping shaft

The shaft is also rustproof

Cons

The line feeding system could use some work

Greenworks

Greenworks
Greenworks is yet another brand that is a staple of this type of technology. While their 40-volt model is not perfect, it does offer a great combination of power and handling.
Expand to see more
Design Type
To be honest, this is one of the better batteries on the market. On top of being 40 volts, you can either choose a 2Ah or 4Ah version and they will charge in 60 minutes and 120 minutes, respectively.

Performance
While this may not be able to outperform some gas units, it can still handle really thick grass. But, depending on the thickness, you may have to take it slowly.

Design Features
Though the variable speed trigger is quite nice, there have been consumers who have criticized the auto feed system. Some have stated that it only works occasionally.

Overall Handling
At 9.2 pounds, this is a bit heavier than some of the other units on this list. Of course, the ergonomic design is ideal for increased comfortability and handling.

Versatility
As the manufacturer notes, the head on this unit is actually fixed. So, for edging, you will simply have to adjust the angle and handling accordingly.

Overall
Some users will settle for nothing less than a trimmer and edger combo and due to the fixed head, this can be difficult to use as an edger. But, for weed-whipping, it certainly does a tremendous job.
Pros

Two times more powerful than 20-volt batteries

Designed with variable speed control

Both battery types offer fast charging times

Cons

Once again, the auto feed system is a bit flawed

Earthwise CST00012

Earthwise CST00012
Truth be told, this had every chance to land in the top five of this list, possibility top three. Yet, it remains at the bottom of this list due to its rather disappointing battery. It is still good, though, make no question about it.
Expand to see more
Design Type
Alright, so here is the biggest issue with this otherwise terrific weed-whipper. As users have claimed, you may get 20 minutes out of the battery so work quickly.

Performance
As you probably already concluded, this is ideal for lighter work and smaller lawns. But, the 7800 revolutions per minute motor can still deliver the goods.

Design Features
This has all the bells and whistles including a telescoping shaft, a flip-down edge guard that protects your flowers, and a semi-automatic line feed system.

Overall Handling
Earthwise went to great lengths to ensure their weed-whacker would be easily handled. With an upper handle that rotates 180 degrees and an auxiliary handle that adjusts left to right and front to back, they accomplished this.

Versatility
Thanks to the fact that this head can be adjusted into three different positions, it can be altered to handle a variety of tasks such as edging.

Overall
It really is a shame that this system did not have a better-designed battery. If it did, it would be easy to consider this model a must-have. But, as it rests, the battery does bring down the overall value a bit.
Pros

Includes a flip-down edge guard

The auxiliary handle adjusts in both directions

Features a lock switch for safety

Cons

The battery life has been crucified

Sun Joe SB601E

Sun Joe SB601E
Now, this is an interesting design here. While you would assume all weed eaters would be designed with string, Sun Joe debunks this assumption with their model as it is stringless.
Expand to see more
Design Type
Sun Joe did not manufacture their weed-whipper to be used via a battery. Instead, you will need an extension cord to power this unit.

Performance
One of the benefits of this model is the SharperBlade technology. With this integrated, hassle-free and reliable cutting is provided. Also, the motor is 4.5 amps and the head 11.5 inches.

Design Features
Many will be enamored at the thought of going stringless. Additionally, the telescoping handle allows you to either extend or shorten the shaft to adapt it to your needs.

Overall Handling
Thanks to the extremely lightweight design, clocking in at only 5.6 pounds, you should have no issues lugging this bad boy around your yard. Of course, the ergonomic handle certainly helps.

Versatility
In just seconds, the 180-degree rotating head will convert to an edger to fulfill your edging needs.

Overall
The fact that you do not need to worry about string could be enough to sell some of you alone. But, when you take into account how easy this is to handle, things get that much sweeter.
Pros

The ergonomic handle is comfortable

Comes with a telescoping handle

There are literally no strings attached

Cons

The blade is made of plastic

The blade guard is probably the weakest part of the machine

Criteria Used For Evaluation

Corded or Cordless

So, the million dollar question is, should you invest in a corded or cordless electric model? Well, even though one may not technically be superior in every way, most consumers will lean toward cordless model thanks to the convenience. With this design type, you never need to worry about an extension cord and having it accidentally unplug during operation. Then again, there are two sides to every coin. While this is nice and all, the issue with battery-operated models is that they are limited with their power. Plus, once they run out of juice, they will need to be recharged. This is never an issue with corded units as it is drawing electricity from another source (such as an outdoor receptacle).

Overall Performance

One of the reasons why consumers typically steer away from electric grass trimmers is due to their performance. Now, it is not as if they can’t perform well but the reality of the situation is this. Gas models are simply going to have more power than electrical models, for the most part. We say for the most part as there are always exceptions to the rule. But, consumers should be able to accept this tradeoff for the benefits of electric (which will actually be detailed later in this guide). Anyway, now that that is out of the way, let’s talk about what to look for in regard to the performance of electric weed eaters.

First off, you can assess the amperage of the motor. An amp is merely the base unit of electric current in the International System of Units. The more amps the engine has, the more powerful it will be. In addition to this, you can also look for revolutions per minute (RPM). This refers to how fast the machine can operate at any given time and, again, the higher the better for more power.

Design Features

Alright, so now it is time to talk about some critically important design features. For starters, you may want to look for systems that run via variable speeds. With variable speed control, you can adapt to different cutting conditions. Plus, with battery-operated units, this can allow you to extend the battery life. Additionally, keep an eye out on the design of the shaft. More specifically, look for an adjustable shaft as this can allow you to adjust the height. To adapt to different heights, this becomes ideal.

Now, it is time to talk about the feed system. Even though not all weed eaters will use string, as one model on this list does not, a majority of them will. What you need to decide is if you want a bump head or an auto head. The former is what most consumers will probably be used to. With this, you need to literally bump the head on the ground to get more line to release. Clearly, this can lead to accidental damage if you are not careful. With an auto head, the system will release line when it becomes short. But, this is not foolproof either because as you have noticed, this system can have flaws. It really is up to you, to which one you decide.

Weight and Handling

It can be easy to focus so squarely on the power and design features that you forget about how important the overall handling is. After all, who really wants to operate a machine that is cumbersome and uncomfortable? The quick answer to this question is absolutely no one. So, let’s take a look at what you should be taking a look at. For starters, you not only want the weight to be kept to a minimum but you also want the weight to be balanced ideally. In other words, especially with battery-operated models, ensure that the front is not significantly heavier than the back.

However, you also need to assess the actual design of the handle. Optimally, the handle will be equipped with a soft grip and also ergonomically designed. With this combination, your hand fatigue should be minimized. The last thing you want is for your hands to cramp up during operation.

Their Versatility

It is true that at their core, all the tools presented for you today are weed eaters. However, most are so much more versatile than that. In specific, you will commonly see weed-whackers also be equipped with the power to do some edging.  Instead of needing to buy an edger on its own, this allows you to combine the tools into one system. So, it is ideal for you to look for that. But, what exactly is an edger and what does it do? Basically, it is a tool that is used to improve the look of your yard by cleaning up around the edges of it. The name really describes the tool and it will create a much crisper look to your lawn.

FAQs

Q:   Why Are Some Shafts Bent and Others Straight?

This is a subtle design feature that you may notice while you are researching. Though it is subtle, it is important for you to know the difference between a bent shaft and a straight shaft. For the most part, you can consider bent shafts to be the cheaper alternative. The reason for this is bent shafts typically are engineered with fewer components. In addition, with a straight shaft, they will generally get under bushes and hedgers much better.

Oh yeah, and bent shafts are typically fixed length and can’t be adjusted. To be honest, besides cost, there is not really much that bent shafts have going for them.

Q:   How Do You Store Lithium-Ion Batteries?

Clearly, this question is only going to be of importance to those of you who invest in a battery-operated model. If you go corded, you can simply skip right over this question, to be perfectly honest. But, if you do have to deal with batteries, you need to understand how to properly store them. For this question, we are going to look at what you do with lithium-ion batteries (as they are very popular and common).

Firstly, there is a certain battery level that you need to store them at. While you may want to store them when fully charged, it is not good for them to fully discharge. So, manufacturers will typically recommend them being stored at around 40 percent capacity. Also, avoid storing them in wet or hot conditions. Ideally, keep it away from moisture and store it in around 60-degree conditions.

Q:   Why Go Electric?

It was alluded to earlier that there are main reasons why it is optimal to switch from gas to electric. While the power of gas models has already been documented, here are some of the main reasons why you would want to switch to electric. For starters, they tend to be more lightweight and tend to be easier to handle. Without all the components that are integrated into a gas model, an electric unit is able to minimize the weight. In addition to this, gas models also tend to be a little louder than electrical grass trimmers.

But, there are two other reasons that play a pivotal role. Firstly, gas models will typically require more maintenance and secondly, they can be worse for the environment. So, you could say that electric units do hold an edge.

Q:   How Do You Clean Them?

Alright, so what happens when you are done weed eating and want to clean your unit? Well, it is certainly not a bad idea to do this as maintaining the weed eater can keep it performing up to the standard that you expect it to. As far as cleaning it goes, you first need to ensure that either the battery is not connected or that no extension cord is plugged in. Once this is done, you can first brush off any loose debris that is on the exterior.

To perform a more thorough clean, go ahead and make a solution of water and soap (not needing too much soap). With this made, take a brush and dip it inside and scrub the deck and handle of the trimmer with it. Once done, rinse and dry off all the parts to prevent any damage in the future.

Q:   Why Does the Line Keep Breaking?

Without a shadow of a doubt, one of the most annoying nuisances that can happen when you are trimming lawns is that the line in your system keeps breaking. This may keep happening and the question then becomes, what causes this to happen? While there can be a plethora of reasons why this happens, the most common would be line crowding. Are you still confused? Well, what line crowding is referring to is the head being held too close to hard objects that can break the line.

Are you beginning to understand now? To reduce the chances of your line breaking, merely keep the line fully extended and avoid getting too close to objects such as fencing, rocks, cement, and bricks.

Q:   What Are the Steps to Cleaning the Air Filter?

This is a really good question to cap this guide off as it addresses something that you need to perform when you own any type of weed eater. You need to ensure that the air filter is cleaned to maintain the performance of the system. For the most part, most designs are universal and to begin, remove the cover that is holding the air filter. Typically, it will be held in place by several screws. Once the cover is open, remove the air filter from the system.

Really, all you need to do to clean it is to use a mix of soap and hot water. Again, you are not going to need to use a lot of soap as the filter is not going to be difficult to clean. Once you have done this, simply allow the air filter to air dry. After it is completely dry, place it back inside, re-apply the cover, and then you are ready to rock.

Final Thoughts

There really is a lot that goes into selecting the right electric grass trimmers. On top of having to decide whether you want a corded or cordless model, you also need to assess their overall design and features. Now that you have read our top ten best electric grass trimmers list you have a better idea for which trimmers suit your needs best.
