Last Updated on January 17, 2022 by

Weed whackers go by many names: Weedeater, string trimmer, whippersnapper, weed whip, or strimmer. They rapidly became a staple of residential and commercial yard work following their popularization in the 1970s and 1980s, and they show no hints of declining in value. Lets talk about electric weed wacker.

For the unfamiliar, a weed whacker is a handheld device that uses a motor to rapidly spin lengths of stiff string. These strings are made of hard material and are used to catch and cut weeds and long grass that grows up around walkways, gardens, and fences. They are an excellent way to finish up basic lawn maintenance without trying to wheel a mower unpleasantly close to permanent fixtures.

However, you might be confused about which weed whacker to invest your time and money in. This helpful buying guide offers a brief overview of what you should look for in one of these devices, and also lists the best ones of 2021 to make your selection simple.

Electric Weed Wacker: What to Know When Picking a Weed Whacker

Weed whackers and string trimmers come in many shapes and sizes, so it can be difficult to tell just what makes a model good or bad. When shopping for one of these devices, some basic information will come up that you need to know to get the one that is right for you. Overall, individuals seeking a weed whacker for regular yard maintenance will want a model that is easy to use, lightweight, has a medium cutting swathe, and uses a reliable automatic or bump feed.

Gas vs. Electric

A major debate about string trimmers is whether a product fueled by gasoline or electricity is better. Gas-powered weed whackers tend to be more powerful, but are large and unwieldy. Electric options that use batteries are weaker but are also small and lightweight. 

For the average homeowner, an electric weed whacker is the better choice because the trimmer will be more mobile and easy to use around edges. The device can also be fueled by charging the battery, meaning there is no additional purchase of gasoline.

Automatic vs. Bump

Automatic vs. bump refers to the system used to feed monofilament string out of the spool so it can be used to trim weeds. An automatic system will sense when the line has been cut and will automatically send out more string, creating seamless use.

A bump feeder, on the other hand, requires the user to pay attention to how much monofilament is remaining. Once it gets low, the individual needs to tap the weed whacker on the ground so more string is released. Bump feeders tend to be more practical because they get caught less. However, an automatic string feeder is ideal when it works properly because it means users don’t need to stop their yard work.

Electric Weed Wacker: Other Qualities

When picking the right weed whacker, there are a few more things to look for. First and foremost is the quality of the trimmer itself. In general, you want a weed whacker that has a sturdy handle, durable guard, and that is easy to transition between using as a general trimmer and as an edger. You should, therefore, look at whether the handle is stagnant if the guard is made out of plastic, and if it’s possible to rotate the head.

Besides quality, you also need to check whether a model is lightweight and easy to maneuver or not. Most weed whackers are considered lightweight once they weigh under 10 lbs. These models are light enough that the average individual who does little to no exercise will be able to use without struggling. A shaft that measures under 48 in. is also ideal, because then the user won’t struggle with a machine that is almost as tall as they are.

Weed Wacker Aspects

Finally, you need to have a look at the cutting swathe. The cutting swathe refers to the area that the monofilament lines will cut, and it is measured by checking the length of each line that is used. So, a weed whacker that uses two strings measuring 6 in. each will produce a swathe of around 12 in. 

The ideal cutting swathe for the average yard is between 10 and 14 in. At 10 in., users will need to be closer to weeds but have control over the cutting path and can avoid obstacles with each. At 14 in., users will be able to eliminate more weeds over a shorter period of time, but the strings are prone to breakage and can get out of hand. The perfect length is around 12 in. since it is the middle ground of both numbers.
