Weed eaters, also known as string trimmers, are very handy tools. They allow us to trim grass and weeds in areas that have obstacles such as walls or areas that the lawnmower can’t reach. Unlike other grass cutting tools that use a blade, the wood eater uses a monofilament line. This line is flexible and easy to replace. Since their invention in the 1970s, many brands have sprung up, making it difficult to choose the best weed eater for your lawn.

If it’s your first time to get a weed eater, or you would like to switch from other grass cutting tools, worry no more. We’ve got you covered. We have had a chance to review most of the weed eaters in the market today. The main aspects we reviewed include the design, price, power system, features. Below is a round-up of the weed eaters that topped our list.

WORX WG160.4 4AH 2.0 Hi-Capacity GT

Rating: 4.1/5

Battery-powered weed eaters offer safety, and this one is the father of them all. Gas-powered weed eaters may fail to start due to poor gas-oil combinations, or too much air in the carburetor.

  • It can share the batteries with other WORX products.
  • Light design and easy to use, even for the aged.
  • Automatic line feed.
What we don’t like
  • There are lots of complains about battery life.

Our Verdict

This is one of the best battery powered weed eaters. You may have to keep recharging it, but the batteries last longer than most.

How to Choose a Weed Eater

The following are the basic features you should look for in weed eater;

  • Additional features such as an edger – Most of the wood eaters can convert to an edger. This allows you to trim when you get to the pavement and then continue trimming other parts of the lawn. Other wed eaters can even function as a blower, or even as a cultivator.
  • Automatic spool feed – The weed eater should be able to feed the string automatically. It should also be easy to load a new string when the older one is worn out. Unfortunately, this feature tends to malfunction, look for weed eaters with a more reliable automatic feed line.

Below are some factors that you need to consider when getting your weed eater.

  • Cutting swath – This is the radius of the lawn that the trimmer can mow at a given time. These vary based on the power and size of the strings. If you have a small area, you can go for weed eaters with a smaller swath. Also, with larger swaths, you’ll take less time and less time to mow your lawn.
  • Power – Wed eaters are either powered by a battery, corded electricity, or a gas engine. Each of these power sources has varying strengths. The power you need should be determined by the density of the vegetation in your lawn.
  • Starting of the gas weed eaters – You need to get the mixture of gas and oil right to start a gas weed eater. However, some are still hard to start even after you’ve ensured everything is inline. Read reviews, and also test before buying to spare yourself frustrations when mowing.
  • Cost – Based on the weed eaters reviewed above, the price range is quite high. More expensive ones come with more advanced features. Cheaper weed eaters are limited in some way, but some still perform quite well. The basic principle is to buy the best item your budget can allow. You also need to understand the maintenance costs. Corded motors will raise your electricity bill, gas weed eaters need gas and oil, and cordless weed eaters need battery replacements.
  • Weight – You have to make sure that the weight is bearable for a long time.
  • Safety – The trimmer head could hurt you or throw debris when left running. You need to get a weed eater with a locking trigger. Some come in the form of a clutch. Just ensure that the safety measure is convenient. Gas weed eaters should also be equipped with eyeglasses, gloves, ear mugs, and other protective gear.

Frequently Asked Questions (FAQs)

How Do I Choose Between an Electric and a Gas Weed Eater?

This depends on where you want to use the trimmer. If you want to trim a field that is quite large, go for the gas weed eater. It will be easier to move around with. Gas weed eaters are also ideal for tough vegetation.

Why Will My Gas Weed Eater Not Start?

First, check whether the on/off button is switched on. Secondly, make sure that the gas and oil have been mixed at a 40:1 ratio. Thirdly, make sure the air filter is clean, the fuel filter should be clean too, and the engine should not be flooded. If it’s flooded, you’ll feel the smell of the gas. Set it aside for some time to allow it to vaporize.

My Weed Eater Keeps Throwing Debris at My Feet; What Do I Do?

You should always purchase weed eaters that have a guard. Also, wear protective gear as you go to mow your lawn. The debris may not always harm you, but if the string happens to break and hit your feet, it will leave some very painful wounds.
