Buying Guide

As you're shopping for the best string trimmer, keep in mind that different products on the market offer their own set of pros and cons. Use the considerations outlined below to select the right string trimmer to match your specific set of demands.xx

Gas or Electric

Before beginning your search, determine whether you would prefer a gas or electric string trimmer. Electric string trimmers require less maintenance than gas string trimmers. They are also easier to get started than a gas trimmer and make less vibration and noise.

If you're interested in an electric string trimmer, you can choose between corded and cordless models. Cordless string trimmers run on lithium-ion batteries. The length of time the batteries will power the trimmer will vary from model to model and could be anywhere from less than an hour to a few hours. If you have a large space, a cordless string trimmer may not be the best choice for you since the battery may die before you finish your yard work.

Corded electric string trimmers are powered through and outlet and will require an extension cord. You won't need to worry about the battery dying, but moving the extension cord around with you as you work can be cumbersome.

Gas string trimmers are often the best choice for larger yards or those who have heavy growth they need to trim. They are more powerful than most electric string trimmers. You also won't need to worry about recharging a battery or dealing with an extension cord.

However, gas trimmers are more challenging to start using the pull cord. You'll also need to take care to make sure you purchase the fuel type recommended by the manufacturer to power your trimmer.

Curved or Straight Shaft

When you look at descriptions for different string trimmers, you'll likely notice that some are described as having a straight shaft while others are described as having a curved shaft. Your height may impact which design is best for you.

String trimmers with curved shafts are generally easier to hold and move around. Their design makes keeping the head perpendicular with the ground easier than it is with a straight shaft string trimmer. For this reason, shorter individuals may find it easier to use a string trimmer with a curved shaft.

If you're on the taller side, you may decide that a straight shaft string trimmer is the best option for you. These models are longer and tall users won't need to bend down to ensure the head of the trimmer is at the low level it needs to be to trim their yard.

Cutting Width

Next, pay attention to the cutting width of each trimmer you're looking at. In most cases, the cutting width of a string trimmer will be somewhere between 12 and 14 inches. String trimmers with a wider cutting width will be able to cut larger areas more quickly.

However, a string trimmer with a wider cutting width will also be larger overall. This can make it more challenging to control and maneuver than a smaller model with a narrower cutting path.

Safety Features

Always keep safety in mind when shopping for a string trimmer. Make sure the model you choose comes with a protective shield to keep debris from flying wildly. You should also take care to wear protective equipment such as glasses, booths, long pants, gloves, and ear muffs (for gas models) when working with your string trimmer.

Convertible Configurations

Many string trimmers on the market are designed as a convertible model. In addition to using them as a string trimmer, you can convert them to other yard tools such as brush cutters, edgers, hedge trimmers, or pole saws. Some models may come with the other components required for the conversions, while others may be sold separately.


Finally, keep your budget in mind when shopping for a string trimmer. Take care not to overspend on something that is more than what your yard requires, but also make sure that you're getting a quality string trimmer that will last for a long time. You don't want to choose something solely based on price only to have it break down and need to be replaced.

Frequently Asked Questions

What is a string trimmer used for?

String trimmers are used to trim areas of the lawn that aren't easily reached by a lawn mower. For example, they are ideal for trimming around fences, trees, bushes, garden edging, and decks.

Do I need a string trimmer?

While you don't have to purchase a string trimmer, buying one should greatly ease your workload when maintaining your lawn. String trimmers are able to help you trim the grass in areas where your lawn mower won't reach, such as the base of a fence or the ground below a tree. Without a string trimmer, these areas will look overgrown and take away from the overall look of your property.

What is the difference between an edger and a trimmer?

Edgers and string trimmers can often be used hand-in-hand, but each serves a different purpose. Edgers are designed to create neat boundary lines, such as along the edges of a sidewalk. String trimmers work to keep these boundary lines looking neat and polished.

Can you edge with a string trimmer?

Yes, you can edge with a string trimmer, but doing so is not easy. You also won't be able to achieve as polished of a look as you would with a dedicated edger.

Are battery-powered string trimmers any good?

Battery-powered string trimmers can be a good choice for users with smaller yards. A battery-powered trimmer may not be able to keep up with the work that is required for a larger yard or yards with overly thick grass or weeds. Battery-powered trimmers don't have as much power as gas trimmers.

Should I mow or use my string trimmer first?

The answer to this comes down to personal preference. Many people prefer to mow first then use the string trimmer to clean up what they couldn't get with the mower. However, others prefer to trim first and then mow. This allows them to use their mower to clean up more of the grass clippings from trimming without getting out a blower.
