Weed eaters vs string trimmers

Terminology is important when looking for lawn care equipment because the same or comparable goods often go by several names. Furthermore, not everyone refers to the same object using the same terminology.

The phrases “weed eater” and “string trimmer” are interchangeable when referring to DEWALT and most businesses. The bladed trimmer is an alternative to the string trimmer that gives more strength and durability but takes more energy, power, and maintenance.

 The edgers, which are used to define borders, can also be used as bladed trimmers. Some weed eaters can also complete this task but lack the same power or tough work efficacy.


Weed eaters can be manual, electric, or gas-powered. However, DEWALT only produces battery-operated electric weed eaters. These are more environmentally friendly than gas-powered weed eaters and produce less air and noise pollution. They are easier to move and store because they are lighter and smaller. However, they may struggle with strong, dense weeds, making them unsuitable for big acreage.

Notably, a DEWALT battery and charger are necessary purchases. With the same charge, DEWALT can utilize the lithium-ion battery with various DEWALT tools.

Dewalt Weed Eater Usage

In specific regions of your lawn and garden, weed eaters are intended to assist in maintaining boundaries. They aren’t necessarily made to create those borders, though. 

An edger, which may dig several inches into the ground to form a barrier, is responsible for doing that. While some businesses provide dual trimmer-edger tools, DEWALT does not at this time. But you can still utilize several tricks we discuss in this buying guide.

The two-handed weed eaters made by DEWALT are best utilized to trim back grass and weeds from flower beds, driveways, and sidewalks. They are very handy in tight spaces than a large lawn mower might not be able to access, like around mailboxes and bushes.

After purchasing a product, register it online with DEWALT. You can look over the warranty and any relevant manuals or instructions.

Dewalt Weed Eater Spools

Weed eaters use nylon thread stored in a spool at the device’s base to trim the grass. You can toggle the setting to control how much of the string is exposed.

 Over time, the nylon string will deteriorate and need a replacement spool. DEWALT provides a Quickload replacement spool that is quick and simple to use. When used, DEWALT spools also “bump” or stretch the feed line as needed.

Cutting swath

Most DEWALT string trimmers have a 12 to 15-inch cutting swath. Even though that might not seem like a big range, every inch counts when caring for your lawn. 

Shorter lengths provide slightly more control and accuracy. Longer lengths could provide more distance and protection from encroaching weeds.


The portability of DEWALT weed eaters is one of their benefits. These instruments are typically under 10 pounds and simple to grasp and use with two hands. Remember that larger tasks require more effort, and setting precise boundaries will necessitate steady machine manipulation.


DEWALT’s weed eaters only have a straight shaft, unlike several competitors who provide customers with the option of a straight or curved shaft. 

Straight shafts typically give workers more freedom on the job and enable access to awkward locations. Curved shafts typically offer greater control and precision, although they may have trouble getting into tight spaces.



DEWALT sells 60-volt batteries that can operate with 20-volt devices and are backwards compatible. This type of DEWALTis is especially helpful if you already own DEWALT tools that only use 20-volt batteries but need a strong weed eater.

Dewalt Weed Eater Bundles

There are DEWALT weed eaters that run on batteries, but not all models do. Consider purchasing a battery and charger kit. Buying these items in bulk should be less expensive than doing it separately. 

However, you might want to pass on the combo if you already have a battery and charger for another DEWALT tool.

Folding shaft

Some DEWALT weed eater models come with a foldable shaft. The shaft can be folded for simple storage and transportation, but it locks in place without compromising durability.

Inexpensive: Weed eaters from DEWALT range in price from approximately $100. These tools work well in confined spaces because of their narrower cutting swaths.

Mid-range: You can purchase DEWALT weed eaters with additional power for between $100 and $150. These implements are appropriate for light and medium-sized tasks.

Expensive: You can get packages or kits, including the DEWALT weed eater, a battery, charger, and even more string spools for $150 and above.

If the ground is soft, you can use the weed eater as an edger by turning it on its side and digging down straight. Hold the gadget firmly and watch out for sharp or rocky objects beneath the surface.


  • DEWALT should cut grass before trimming. A strong tool that can make trimming simpler is your lawn mower. First, trim the grass and weeds. Then, for a more precise trim, use the weed eater.
  • Check the direction of the weed eater. The path of cut grass and weeds is indicated by the direction in which your weed eater revolves so that the grass moves where you want it to as you walk.
  • Take a look around. Check the area for rocks, pebbles, roots, and other debris before you start working. Some objects might harm the weed eater, while DEWALT might direct others at you or others.
  • Don’t forget to charge. Make it a practice to recharge your battery after each use. A dead battery immediately derails any outside upkeep plans. It can take one to two hours for DEWALT weed eater batteries to fully charge.


DEWALT’s line of weed eaters offers a wide variety of options. There are several models to fit different sizes, job types, and budgets. Whether you need to tackle a large lawn or maintain a small one, there’s a DEWALT weed eater suited to your needs.

The devices are easy to use and durable, making them an ideal choice for homeowners who want their yard to look professionally manicured at all times. Researching this guide has led us to discover that DEWALT’s offerings are top-notch and worth your consideration when you want an effective tool to help you maintain your lawn.

How do I best maintain my weed eater?

Remove dirt, soil, and other debris from the head of your weed eater after use to prevent it from setting and interfering with subsequent operations. The weed eater should be kept in a cool, dry location away from heat and moisture. Keep the battery and charger together in the same area. The spool will eventually need to be replaced, but aside from that, maintaining a DEWALT electric weed eater should be minimal at best.

How safe are weed eaters to use?

Weed eaters, like the majority of outdoor tools, are generally safe as long as you know how they operate and follow the necessary safety precautions.

Particularly gloves can assist keep your hands from hurting.

What are the best ways to prolong battery life?

DEWALT cautions against entirely draining the battery. When you find your device deteriorating, turn it off. Because the charger’s maintenance mode guards against harm, you can leave the battery in it indefinitely. However, if the battery is warm or heated, you should avoid charging it. Instead, wait about an hour at room temperature before using it.
Charge up your DEWALT weed eater battery to 100% before putting it away for the winter. The battery can be recycled after it dies.
