Top 7 Weed Eaters to Buy in 2020

Last Updated on

Weed refers to all types of plants that undesirably grow at any place and are not welcome. Their positive qualities are perhaps more than the negatives. Therefore, no one cares to have them grown in their lawns.

Weed plants are dangerous and must be avoided. First of all, weed occupies the land and stops the growth of grass. Secondly, it badly impacts the health of grass by soaking all the nutrients from the soil. Thirdly, they invite insects to take shelter into it and fourthly, it produces chemicals that are harmful to animals that graze on grass and human beings.

Therefore, it is important to remove uninvited weed from your lawn. In the pursuit of getting rid of weed and the invaders invited by it, many folks prefer to use pesticides and herbicides which cause serious health problems including cancer.

Peter Bergkvist of the Swedish Chemicals Inspectorate (KEMI) once reported that Swedish regulators were committed to reducing the risks of pesticide use. Their aim was to suggest the less risky substitutes that were available. It would have been much better if the world could get rid of even lesser risky substitutes for the sake of good health.

In this article, we are intended to provide you with a better alternative to whack the weed in your lawn. We will discuss some best performing electric weed eaters to equip you with the knowledge required to choose the best electric weed eater for your lawn.

Buying Guide


Lightweight weed eaters are easy to handle and manoeuvre around. Gas-powered and cordless weed eaters are usually heavier than corded weed eaters as they don’t carry a heavy battery and power equipment like in gas-powered mowers.


Electric weed eaters make almost no noise as compared to gas-powered weed eaters. You can use an electric weed eater even in the evenings if you have proper lighting in your lawn and it won’t disturb your neighbours.


Buying such products every year or spending money on their maintenance will break your bank. So, it is important to spend your money wisely after deliberate considerations. Always search for products that are backed by a warranty or a money-back guarantee to protect your investment. Buy a product only after knowing what it is offering.

String size:

If you are buying a weed eater for a lawn covered with tough weeds and bushes, you should buy a weed eater with a diameter equal or greater than 0.085 inches. Smaller the diameter size, weaker the like will be. If you still want to buy a weed eater with a thin string, at least buy a string with better quality for smooth operation.

Line feed:

There are some weed eaters with a feature that automatically advances the line when needed and there is some called bump feed. They release the line on gently bumping their heads on the ground. The third category of the weed eaters feeds line on the push of a button.

Important Tips


Whenever you buy a weed eater, always try to find a versatile one that is built to be compatible with maximum attachments. Such weed eaters can be used year-round and provide maximum lawn care. You can find many of them online, available at comparatively low prices but with maximum services in one unit.


If you are not a regular user or a new user, I would refer you to buy a weed eater with the following features.

  • Good wheel support in case you use it for edging
  • An auxiliary handle for better support
  • A strong shaft
  • Lightweight weed eater so ensure manoeuvrability
  • Automatic line feed to avoid the hassle of bumping the head of the weed eater
  • Spacer Guard so that you won’t trim down ornamental plants and flowers.


Weed eaters with better features and performance would cost you more money. If you have a small yard or a lawn that requires little maintenance an inexpensive weed eater will do the job.

Which one is better? A straight shaft or a curved shaft.

Although both perform the same function, there is a slight difference between how they perform. The straight shaft is good as it is long enough to reach straight under the plants and remove weeds. On the other, hand, curved shaft eaters are a bit shorter and therefore, easy to handle.

As a matter of fact, they are good at performing their job. It’s the consumer’s choice to decide which one will suit them based on their own height and lawn size.

What are the types of weed eaters?

There are so many types of weed eaters i.e. gas-powered weed eaters, cordless weed eaters, 4 stroke weed eaters, electric corded weed eaters, and commercial weed eaters. For a better understanding of them, please read the article above.

Are electric weed eaters as good as gas?

In terms of power, gas-powered weed eaters are more powerful and perform better than electric weed eaters but the electric weed eaters are better for being environmentally friendly. Electric weed eaters do not make noise and do not emit gases hazardous to our environment and health.

How to change the string?

Changing the string is requires having the correct replacement. First of all, you need to figure out which string is compatible for your weed eater as there are many but there is only one that your weed eater will operate with. It’s is better to call the manufacturer’s helpline to buy the correct one.

Almost all manufacturers have a little bit of different equipment from each other. So, suggesting one method won’t solve the problem. We suggest you call the customer support or use the product’s user manual.

Are there any weed eaters without string?

Operating a string weed eater or replacing the string can be uneasy for some people. Such people have an option to buy a weed eater without a string. Weed eaters without string whack weed with a spinning blade and they are available in the market.
