A variable-speed trigger is conveniently located on its ergonomic grip, allowing you to select high speed for added power or low speed for longer battery life.

You can adjust the cutting swath from a diameter of 15 to 17 inches, and because it’s a variable-speed trimmer, you have the option of selecting a more powerful operation or a longer running time. Indeed, with so many ways to adjust this trimmer to the task at hand, it’s a great option for anyone who wants to consolidate their lawn tools and complete more jobs with less equipment.

How we analyzed

We researched every DeWalt weed eater currently available to assemble our list of the top four models. During our research, we looked at each model’s battery power, spool options, cutting width, shaft type and price to determine which models provide the most value. And because it’s also important to be comfortable while you work, we considered whether each had an ergonomic design and how heavy it would be to carry.

Key considerations

Power

Weed eaters may be gas-powered, electric or manual. The only electric weed eaters DeWalt offers are those powered by a battery. These are better for the environment and create less air and noise pollution than gas-powered weed eaters. They are lighter, smaller and easier to store and transport. However, they aren’t ideal for large plots of land and may struggle with tough, dense weeds.

Notably, you will need to invest in a DeWalt battery and charger if you don’t already own these items. The lithium-ion battery can be used across various DeWalt products, provided the charge is the same.

Usage

Weed eaters are designed to help maintain boundaries in certain areas of a lawn or garden. However, they are not necessarily designed to manufacture those boundaries. That’s the job of an edger, which can dig several inches into the soil to create a barrier. While some companies offer trimmers that convert into edgers by swiveling their heads to the side, DeWalt currently does not. 

The company does, however, offer weed eaters such as the DeWalt 60-Volt Max Brushless Attachment Capable String Trimmer, which allows you to swap out trimmer heads for other tools including edgers, chainsaws, hedge trimmers and even leaf blowers.

With such a modular design, your weed eater can be just as handy pruning small, overhead tree branches as it is keeping weeds and overgrowth under control.

Spool options

Weed eaters trim grass with a nylon string that is housed in a spool at the base of the device. The nylon string wears down over time and requires a replacement spool. 

Winding a new trimmer line into a weed eater’s spool can be a time-consuming and frustrating hassle. Thankfully, DeWalt offers a Quickload feature that makes refreshing your string as easy as threading it into the spool and winding it into the head with a ratcheting motion.

DeWalt trimmers feature bump-feed spools. While you’re working, you simply bump the trimmer head on the ground to release more string as needed. 

Cutting swath

Most DeWalt string trimmers have a cutting swath of 12 to 17 inches. While that may not seem like a big range, every inch makes a difference when tending your lawn. Shorter lengths offer a bit more control and precision. Longer lengths may offer more protection and distance from encroaching weeds.

Weight

One of the perks of DeWalt weed eaters is portability. Generally, these tools weigh around 10 pounds and are easy to hold and wield with two hands. Keep in mind that bigger jobs require more energy, and creating precise boundaries calls for a steady handling of the machine.

Shaft

Some companies offer a choice of a straight or curved shaft, and DeWalt is no exception. However, DeWalt only offers curved shafts on its gas-powered trimmers. Straight shafts generally offer more flexibility on the job as well as the ability to access hard-to-reach places. Curved shafts generally offer more precision and control, but they may have difficulty accessing hard-to-reach places.

Features

Flexvolt

DeWalt offers 60-volt batteries that are backward-compatible and can work on devices using 20-volt batteries. This is especially useful if you need a powerful weed eater but own other DeWalt items that only require 20-volt batteries.

Bundles

DeWalt weed eaters are battery-operated, but not all units come with the battery. You may want to purchase a bundle that includes a battery and charger. Buying these items together should be cheaper than buying them separately. That said, you may want to forgo the bundle if you already have a battery and charger for another DeWalt device.

Folding shaft

Select models of DeWalt weed eaters have a folding shaft. The shaft locks into place when in use without sacrificing durability, and it can also be folded for easy storage and transport.

DeWalt weed eater prices

Inexpensive: The least-expensive weed eaters from DeWalt start around $130. These tools have smaller cutting swaths and don’t include a battery or charger.

Mid-range: For between $150 and $200, you can find DeWalt weed eaters with more power. These tools are suitable for jobs of small and medium size.

Expensive: For $200 and up, you’ll be able to buy bundles or kits that include the DeWalt weed eater as well as a battery, charger and even additional string spools.

Tips

  • Cut the grass before trimming. Your lawn mower is a powerful device that can make trimming easier. Mow grass and weeds first. Then, use the weed eater for a more accurate trim.
  • Assess the weed eater’s direction. The direction your weed eater rotates indicates the trajectory of cut grass and weeds. Keep that in mind when you’re walking so the grass goes where you want it to.
  • Survey the area. Before you begin work, check the area for rocks, pebbles, roots and other debris. Some items could damage the weed eater, while others could be projected toward you or others.
  • Remember to charge the battery. Get into the habit of charging your battery after use. A powerless battery quickly deters any outdoor maintenance plans. DeWalt weed eater batteries can take one to two hours to fully charge.

FAQ

Q. What’s the best way to maintain my battery-powered weed eater?

A. After using your weed eater, remove dirt, soil and other debris from the head so it doesn’t harden and disrupt future use. Store the weed eater in a cool, dry place away from moisture and heat. The battery and charger should be kept in a similar space. 

Over time, you will need to replace the spool, but otherwise, a DeWalt electric weed eater should require little to no maintenance. 

Q. How safe are weed eaters to use?

A. Like most outdoor tools, weed eaters are relatively safe provided you understand how they work and take proper precautions. Even with a guard on the head, however, they can still fling dirt, pebbles and other debris. Protect your eyes, hands, wrists, feet and ankles, as these are the most sensitive or vulnerable areas of the body. Gloves, in particular, can help prevent your hands from getting sore.

As DeWalt weed eaters are battery-powered, you needn’t worry about cords tangling up, but it’s best to keep pets and children away while you’re working. 

Q. What are the best ways to prolong battery life?

A. DeWalt advises you to avoid running the battery down completely. Turn off your device when you notice it weakening. You can leave the battery in the charger indefinitely, as the charger’s maintenance mode prevents damage from occurring. However, you should avoid charging the battery if it is warm or hot. Instead, leave it at room temperature for an hour or so first.

Prior to the off-season, fully charge your DeWalt weed eater battery before storing it. Once the battery is dead, it can be recycled.
