How We Picked Top Products

Picking up the best grass trimmer is not a simple task, we indeed did hours and hours of research to know which one is the best and which stands out from the others. After that, we picked up a few models that are highly efficient and powerful. If you think you are getting confused after reading those reviews, make sure to check out this guide, which is full of core factors.

Power Type

While you are going to buy the best corded electric string trimmer, make sure to consider the power type first. The market indeed has three different choices in general, including corded, battery-powered, and gas-powered.

In sum, the gas-powered includes lots of energies, yet it is costly, need expensive things to run, and most are loaded with a bulky structure.

A battery-powered string trimmer, on the other side, equips moderate power but this type is basically compact, lightweight, and user-friendly.

In fine, a corded version is a better combination of both lightweight, power, and affordability. But at the end of the day, it is all up to you! 

Cutting Width

You have landed on the most necessary factor. We usually can guess a trimmer’s performance by knowing its cutting diameter. A big cutting path means you will be able to cut lots of weeds or grasses in one go.

Our one of the favorite choices Greenworks 21142 equips a wide 18-inch cutting path, which means you can cut heaps of grasses or weeds at once. 


Whether it is a corded, cordless, or a gas-powered trimmer, it needs adequate amounts of power to make your lawn healthy and weeds-free. A corded version takes energy from a motor, which means you have to get yourself a trimmer with at least 4.0 amp, and 10.0-amp will be more than enough for bearing a lot of torture.

If you want to go with a cordless version, then choosing a battery with 40V will be a wise decision. 

Size and Weight

It matters a lot, especially when you are highly involved in lawn-care projects. It is too annoying to hold a trimmer for a long time. Even our hands get fatigued very soon while we carry a string trimmer with bulky structure. For minimizing discomfort, you can go with our BLACK+DECKER BESTA510 that is just 3.19 pounds for assuring portability.

You should also focus on the size of your trimmer, which should compact and pretty small for which you can enter in tight areas with less effort.

Dual Function

In the marketplace, a few trimmers include a 2-in-1 system, which means you can use it as a trimmer and edger at the same time. This could be an extra plus for accurate landscaping. 

What is Electric String Trimmer? 

An electric string trimmer is a type of lawn-care equipment that is designed for cutting grass, overgrowth, or weed in a simple way. This type basically takes energy from electric current using extension cords. The corded or electric string trimmers are mostly affordable, lightweight, and includes a lot of power to trim the unnecessary grasses of your lawn or garden. 

Type of String Trimmer Heads: 

Alongside the power type of a trimmer, you have to pay attention to the string trimmer heads. Here you will find three different heads, including:

Bump Feed: This type basically originates from a string. You will be able to manage the length of its line for use. And thankfully, the way of repairing this head is a piece of cake!

Automatic Feed: Almost similar to the previous one (bump feed). Nevertheless, it packs a line spinning motor instead of manual control. It is not necessary to keep on focusing on the line, which seems a good thing. 

Fixed Head: It packs specific lengths of line for which you will be capable of threading into your device without stopping. This type of head includes a thicker string, which makes it ideal for commercial uses. 

How Does Electric String Trimmer Work? 

You can call a string trimmer in a variety of names, such as liner trimmer, weed whip, weed whacker, brush cutter, and many more. This hand-held lawn-equipment is designed for cutting grass, weed, overgrowth, or such type of unnecessary things. Not for trimming only, a string can be used for edging also.

Let’s move on to a string trimmer with electric version. This type contains enough power, packs a moderate weight, relatively handy, and ease of use. Besides, it requires no harmful ingredients, so you can call it an environment-friendly tool.

An electric brush cutter uses extension cords to get power from electric currents. It contains a powerful motor with a decent weight to make it capable of taking heavy pressures. Besides, its individual cutting diameter is loaded with thickness and sharpness for slicing numerous types of grasses at once. Because of its compact size and moderate weight, anyone can use it with ease. 

Tips While Using String Trimmer: 

Here, we are providing a few tips that will help you in making your task perfect, accurate, and danger-free:

  • Picking up the best trimmer should be your first duty if you want to get the highest benefit from this tool.
  • Since you are going to operate a power tool, do not forget to put on safety dresses, including gloves, boots, safety glass, and a piece of earplug.
  • While trimming or edging, you must have to keep focused on the cord. The tool might destroy its cable that will lead to a serious accident.
  • Before making a trim, ensure to clean up the surroundings as much as you can. Make sure to castaway the plastics, papers, or such types of materials from your lawn. 

How to Fix Electric String Trimmer: 

Fixing an electric string trimmer is not as difficult as it seems. However, you have to earn enough knowledge concerning the way of fixing. Otherwise, you might get some negative results unexpectedly!

Power Issues

At first, you have to find out the issue of your trimmer. If the problem is related to power, then you have to move on to your tool’s motor and cord. Turn it on and see what is going on.

If you see your weed whacker is running too slow, it is a sign of a damaged motor. Sometimes, you might have to change its cord. When you see the power is turning on or off itself without switching, you have to change the entire plug as soon as possible. 

The Issue of Line 

We always suggest cutting massive-sized weeds with additional blades. But if you want to trim it with your string trimmer, then it should be quite powerful, as well as you have to change its line after using a few years. 

In case you are using a trimmer line for around 5-7 years, it is highly essential to buy a new one. 

How to Clean Electric String Trimmer

Cleaning your electric string trimmer is a need if you are a regular user. After using it for a couple of months, it gets jammed and seems fragile. Go down below to know how to clean it in the right way:

  • Remove the source of power before start the cleaning task.
  • Now, it is time to remove the specks of dirt or debris. You can take a piece of regular brush to wipe it off. If it gets stuck with junks, ensure to collect adequate amounts of soapy water for making it clean.
  • After washing it off, do not store it straight away. Wait for a while to make it dry.
  • If you run your tool for around 10 hours in total, make sure to clean up the filter using freshwater. 
  • You should also clean up the spark arrestor at a specific time. The carbon cleaner and wire brush are required for cleaning it efficiently. 

Straight Shaft vs Curved Shaft? 

Having an efficient string trimmer is a must if you want to ensure better care of your lawn, but which should you buy, straight or curved shaft? This particular question is nowadays, making a BIG confusion among the liner trimmer users. Don’t worry, we are going to explain for your convenience.

Both types are usually used for trimming unnecessary grasses, but the string trimmer with straight shaft packs more advantages. 

Curved Shaft Trimmer

This type is quite popular among beginners. You do not have to expend a lot of cash to get it since it is relatively cheaper compared with a straight shaft. And for its moderate weight, anyone can enjoy their lawn-care projects by reducing all kinds of fatigue. But keep in mind, its blade is not that powerful and unable to cut all types of grasses or weeds.

Using this type is a big hassle for tall users, only for its curved shape that appears uncomfortable to use since you might have to reach down a lot while operating it. 

Straight Shaft Trimmer

“Power” is the first word that comes to our mind when we talk about a straight shaft trimmer. This type includes more energy, yet offers less vibration. Unlike the curved version, its cutting path is more effective and able to make precise cuts at a go. No matter you are short or a tall guy, you can reach in tight areas without much effort. 

But the only downside is, you have to spend more amounts of cash if you want to have a decent straight shaft, unfortunately. 

Final Verdict

Without a doubt, Greenworks 21142 is our clear winner when it comes to picking up the best corded electric string trimmer. It features a 10.0-amp brushed motor, a straight shaft with a 4-cycle engine, a unique cord lock feature, and most importantly, its 18-inch cutting path makes it one of the most efficient trimmers out there.

Our second place goes to the BLACK+DECKER LST136. Its 40V lithium-ion battery makes it capable of taking enough pressure. Besides, the tool equips an automatic feed spool, which allows you to work at a stretch. Alongside these features, we are fond of its rubber-molded grip that adds additional comfort while trimming.

We are going to conclude our top-priority list by featuring BLACK+DECKER BESTA510, which easily stands the third position. Its 8000 RPM ensures that you can trim heaps of grasses without spending hours and hours, and the most important thing is, it just packs a weight of 3.19 pounds, which allows users to hold it without much effort.
