Popular Mechanics' heavy-duty pick: it cut weeds, briars and dense growth and takes blower, hedge and pole-saw attachments. It's the heaviest trimmer PM tested (14.2 lb), and its small 60V battery limits runtime. Wirecutter found DeWalt trimmers short on runtime and power next to EGO.
In the box: Yes: 1 x FLEXVOLT 9Ah battery (3Ah when used at 60V, per Popular Mechanics) and charger (Amazon listing title)
Top complaints
- Short runtime
Popular Mechanics lists limited runtime as a con: the FLEXVOLT battery is only 3Ah at 60V. Wirecutter says DeWalt's trimmers lacked the run time of its EGO picks. Some Amazon owners say the battery runs down after about 30 minutes.
- Heavy
At 14.2 lb it's the heaviest trimmer Popular Mechanics reviewed, though testers found the balance acceptable. Weight is mixed on Amazon.
- Stock head wears out, mixed value
Some Amazon owners say the stock head wore out within a month. Durability and value for money are mixed, and Wirecutter notes it typically costs around $350.
What owners love
- Heavy-duty cutting
Popular Mechanics testers cut weeds, grass and light-to-medium briars in an overgrown drainage basin. Amazon owners say it has plenty of power and outperforms gas trimmers.
- Attachment system
It converts to an edger, brush cutter, leaf blower, hedge trimmer, pole saw or cultivator with optional attachments (Popular Mechanics). Wirecutter notes it has a larger debris guard than other DeWalt trimmers.
- Two speeds and clean edging
High and low speeds; tipped vertically, it cut a neat edge along a sidewalk and curb (Popular Mechanics).
- Weight is a concern
- You need long runtime on one battery
- You're on a budget
- Dense weeds and light brush
- Owners of DeWalt 20V/60V batteries
- Adding attachments (blower, hedge trimmer, pole saw)

What experts say
- Popular Mechanics (best string trimmers): Best heavy-duty battery trimmer: powerful and precise in dense undergrowth, but heavy (14.2 lb) with limited runtime.
- Popular Mechanics (best battery string trimmers): Best multi-head: a powerful base for a reasonably priced attachment system, held back by a small 3Ah battery.
- Wirecutter (NYT): Not a pick: DeWalt trimmers are light and comfortable but lack the EGO's runtime and power, and this model typically costs around $350.
