Gas Versus Electric Weed Eaters


Keeping the lawn in shape or working as a landscaper requires the right set of tools in your arsenal. One of the most useful tools can be your weed eater (also called a string trimmer), but only if you get the right one. You have a lot of choices for weed eaters with one of the most significant being whether it is a gas or electric model.

Both gas and electric models have their good points and their bad points. Here’s a simple comparison of each type that can help you make the right decision for yourself:


A gas operated weed eater runs off of a small motor that is fueled by a mix of non-ethanol petrol and oil. Most gas trimmers run with high cutting power and thicker trimming string than electric trimmers, making them very effective against most of the small brush and weeds you will encounter.

Because gas trimmers run on fuel, they do not restrict your movement at all. However, these weed eaters are generally much heavier than electric trimmers, weighing at least 6 – 10 pounds. If you want something that is heavy duty and built to last for years, a gas trimmer might be a good option for you.


  • More power
  • Longer run time
  • Freedom of movement
  • Sturdy equipment build


  • Heavier
  • More frequent maintenance required
  • Specially mixed fuel is a must


There are two classes of electric weed eaters: battery powered and corded. Corded electric trimmers plug into any household outlet while battery powered trimmers operate from rechargeable, removable battery packs. In general, electric weed eaters don’t have as strong of cutting power as gas models, but they have enough to cut most of the common weeds and non-woody grasses.

Getting an electric trimmer almost guarantees you a lightweight machine, even if you choose a battery operated model. Since there is only a small engine attached to the body of the weed eater and you don’t have to carry around the fuel, electric trimmers are great for those with a smaller build who are not in need of very high cutting power.


  • Very lightweight
  • Batteries charge quickly
  • Strong enough for an average homeowner’s lawn
  • Little to no maintenance required
  • Less expensive to purchase


  • Shorter running time on battery models
  • Less power than most gas trimmers
  • Corded units restrict movement



Based on the above information you can see that gas weed eaters appear to be better for those looking to use the trimmer commercially, anyone who needs very strong cutting power, and for anyone with a huge yard to trim. Electric models on the other hand are perfect for people who want a more lightweight device, anyone with a medium sized or small yard (battery users can buy extra batteries for larger spaces), and for people without the need for strong cutting through brush.

The choice is up to you. Read through some reviews of a few of the top products on the market and see which one might be the best for your specific needs.
