Understanding String Trimmers
String trimmers are essential tools for anyone serious about yard work, making it easy to trim grass and weeds in spots your lawnmower just can’t reach—like along fences, around trees, and near garden beds. These versatile machines come in several power options, including gas, corded electric, and cordless battery-powered models. For most homeowners, cordless string trimmers, especially those in the 20V MAX range from DeWalt, strike the perfect balance between power, convenience, and access to tight spaces.
Choosing the right string trimmer depends on your yard’s size, the type of grass or weeds you’re tackling, and how much power you need for the task. DeWalt’s 20V MAX string trimmers are a favorite for their durable build and reliable performance, making them a smart buy for a wide range of yard tasks. When comparing options, consider not just the specs, but also the brand’s reputation for making tools that last and deliver results day after day.
Power & Performance: Why The Brushless Motor Matters
DeWalt’s high‑efficiency brushless motors replace traditional brushed designs, reducing friction and heat so more battery energy turns directly into cutting power. On the 20V MAX 14‑inch trimmer, the brushless motor helps maintain strong torque while extending runtime, which is crucial when you’re edging, trimming around obstacles, and clearing fence lines in one session. The 60V MAX FLEXVOLT trimmers push that further with higher RPMs, larger cutting swaths, and the ability to run thicker line that bites into dense weeds and light brush similar to a gas unit.
In independent testing, the 60V MAX 17‑inch model runs roughly 13–14 minutes in high gear with a 9.0Ah FLEXVOLT battery under load, or around 25 minutes in low, which is impressive given the wide swath and high speeds. Many users offset that trade‑off with a second battery, but the key win is the balance of power and control: low gear for weekly maintenance, high gear for overgrown corners and ditch lines.
Design & Ergonomics: Built For Real‑World Yards
DeWalt clearly designed these trimmers with real storage and transport constraints in mind. The 20V MAX folding model uses a hinge in the shaft to reduce overall length by about 40% when folded, making it much easier to tuck into small garages, sheds, or truck beds without removing parts. The straight‑shaft layout with adjustable front handle gives good reach under shrubs and along fences, and the trimmer head has a 14‑inch swath tuned for 0.080‑inch line that’s ideal for residential yards.
On the FLEXVOLT side, the 60V MAX units are built heavier and more robust, with a 15‑ to 17.5‑inch cutting swath and support for 0.095‑ to 0.105‑inch line, so they feel more like pro‑grade gas trimmers. Reviews from long‑term owners often note that the 60V trimmer “is as powerful as any gas model” they have used, especially in high mode with heavier line. Despite the power, vibration is kept manageable, and the long, straight shaft keeps the head where you need it without forcing you to hunch over.
Ease Of Use: From Trigger To Line Reloads
One of the biggest advantages of these DeWalt weed eaters is how simple they are to live with day‑to‑day. The variable‑speed trigger on the 20V MAX and 60V MAX models lets you feather power when working near delicate landscaping, then squeeze harder for full output when you hit thicker grass. A two‑position Hi/Lo speed switch gives you predictable runtime control, so you can deliberately stay in low for most trimming and only toggle high in problem areas.
Line replacement is also painless. DeWalt’s QuickLoad or bump‑feed style heads allow you to feed in a new length of string and wind it quickly, without needing to disassemble complicated spools. Homeowners consistently highlight that the combination of cordless operation, push‑button starting, and quick line changes makes these trimmers much less intimidating than gas options, especially if you only trim once a week.
Safety Precautions
Safety should always come first when using string trimmers. Before you start, put on eye protection and sturdy shoes to shield yourself from flying debris. Make sure pets and bystanders are well clear of your work area to prevent accidents. If you’re using a gas-powered model, never operate it in enclosed spaces to avoid dangerous fumes.
Always ensure you have the proper permission to use your tool, especially if you’re working on a shared lawn or near sensitive areas like a server room. For cordless models, handle batteries with care—follow DeWalt’s charging and storage guidelines to keep your tool and yourself safe. And if your string trimmer or its accessories require internet access for updates or features, double-check your http connection before starting your task. Taking these precautions helps you finish your yard work safely and efficiently.

Inspect accessories and attachments as well, making repairs or replacements as needed to prevent accidents and keep your yard work running smoothly.
When it’s time to put your string trimmer away, store it in a dry, secure spot—out of reach of children and pets. Consider using a lock or other security measure to control access and prevent unauthorized use.

FAQs
Is a DeWalt weed eater as powerful as gas?
The 60V MAX FLEXVOLT trimmers are frequently compared to gas models in user reviews, with many owners saying they match or exceed the power of typical homeowner gas units for everyday trimming and heavy grass. For the very thickest brush, a pro gas unit still has an edge, but for most residential and light commercial work, the 60V MAX holds its own.
How long does the battery last?
Runtime depends on the battery size, speed setting, and cutting conditions, but testing shows the 60V 17‑inch trimmer can run about 13–14 minutes in high and around 25 minutes in low with a 9.0Ah FLEXVOLT battery under typical trimming loads. The 20V MAX 14‑inch trimmers generally deliver a full yard’s worth of trimming on a single 4.0–5.0Ah battery when you mainly use the lower speed.
Does the DeWalt trimmer use standard trimmer line?
Yes. The 20V MAX models are designed around 0.080‑inch line, while the 60V MAX trimmers support 0.080–0.095‑inch line and, on some 17.5‑inch models, up to 0.105‑inch for more aggressive cutting. Always match line diameter to the manual for your exact model.
Can I use my existing DeWalt batteries?
If you already own 20V MAX batteries, you can use them with 20V MAX trimmer models (tool‑only versions are widely sold). FLEXVOLT batteries can power compatible 20V MAX and 60V MAX tools, but standard 20V MAX packs will not run 60V MAX trimmers.
How hard is it to change the string?
DeWalt’s QuickLoad and bump‑feed heads are designed to make re‑stringing quick; you typically cut a length of line, feed it through the head, and wind it by turning the outer ring instead of disassembling the entire head. Most users report that once you’ve done it once, it becomes a fast, low‑frustration process.
Final Thoughts
If you are already in the DeWalt 20V MAX or FLEXVOLT ecosystem, the brushless weed eater is one of the highest‑impact yard tools you can add to your lineup. The combination of efficient brushless motors, smart ergonomics, and easy‑to‑live‑with cordless operation makes these trimmers a strong upgrade over corded electric units and a serious contender to gas for most property owners.
For small to medium suburban yards, the 20V MAX 14‑inch folding trimmer hits the best balance of power, runtime, storage, and price. For large properties, heavy weeds, and users who never want to fight a pull‑cord again, the 60V MAX FLEXVOLT trimmer delivers near‑gas cutting performance with the convenience of a battery pack and a trigger.
