String Trimmer Buying Guide


Often referred to as a weed wacker, string trimmer, weed eater, or line trimmer, this tool is essential for complete yard care and maintenance. String trimmers are invaluable in helping to knock down those blades of grass your mower can’t reach such as around shrubs or fence posts. When we talk about using them as a form of weed control, they are referred to as weed whackers or weed eaters. Either way, it is the same tool serving a different purpose. These tools work by using a flexible line or string instead of a blade to cut through grass and weeds. It is important to note that while string trimmers can be used for edging lawns, we are not referring to edgers, which are a completely separate outdoor power tool. There are a range of string trimmers on the market with a variety of different features. They can be narrowed down into three main groups: gas-powered, battery-powered, or corded.

Gas-Powered String Trimmers

As the name suggests, gas-powered string trimmers require gasoline to run. They typically run on 2-cycle gasoline, which requires mixing gas and oil for the engine. Gas-powered models offer a longer running time than battery-powered models and are usually lighter in weight. Gas-powered trimmers are better for larger jobs and tend to be the most powerful option.

Electric String Trimmers

For smaller jobs or ones that are closer to the home (and therefore an outlet), electric string trimmers are a good option. They offer a reasonable amount of power and can handle most basic jobs around the home. As long as you are plugged into an outlet, electric string trimmers can run as long as you need them to. The downside is that the length of your extension cord limits the range of use.

Battery Powered String Trimmers

Battery operated string trimmers offer the best of both gas and electric string trimmers. You have the mobility of a gas-powered machine with the benefit of not having to mix gasoline for the engine. Battery-powered string trimmers tend to have less power than gas-powered trimmers.

Shaft Types

String trimmers have two different shaft types–straight or curved. The shaft type is generally a matter of preference and comfort for the user. A curved shaft can be slightly more comfortable to hold for the user over long periods. Straight shaft trimmers offer users a bit more length to reach underneath shrubs or around fence posts. Both have their benefits and are ultimately a feature that simply comes down to preference.

Head Types

There are three main types of head-feeding systems for string trimmers–bump-feed, automatic feed, and fixed-line systems. With a bump feed trimmer, you simply bump the trimmer head on the ground to activate a spring-loaded mechanism. This feeds out a new length of the line from the coil inside the head as necessary throughout the job. Automatic feeds use the same type of mechanism that bump-feed heads use to replace the line automatically. Fixed-line systems use individual lengths of line that are loaded into the trimmer one at a time. Each of these feeding systems have their own pros and cons as well.

Best String Trimmer Resources

Trying to discern legitimate reviews from paid or sponsored reviews can be difficult. It is hard to determine what content online is from somebody who knows what they’re talking about or somebody who got paid to say something good about a specific product. We have compiled a few of the best resources when it comes to purchasing a string trimmer to take the guesswork out of them.

For decades, Consumer Reports has been a go-to resource for buying anything from cribs to cars. And yes, they reviewed string trimmers, too. Experts tested 68 different models of string trimmers to bring the best to buyers. They performed unbiased tests for things like trimming, edging, handling, and ease of use.

Lowe’s offers a comprehensive buying guide as well. Their short 40-second video helps narrow down the selection process by asking a few questions about how you intend to use your trimmer. How mobile do you need to be? Where will you be working? How long will you be working? They also offer a small chart to help identify the type of string trimmer you will need to get the job done.

The Sweet Home reviewed seven different models of string trimmers. Testers cleared over 12,500 square feet of an overgrown field and over 6000 linear feet along walls and fences to provide us with results that can be applied to our own homes. Not only did a clear winner emerge from testing these trimmers to their fullest potential, but they also give some good picks for runners up in a variety of price ranges.
