This is the heaviest-duty DeWalt trimmer and the one to buy for ground that makes other trimmers struggle. A brushless motor with two speeds drives a 15 inch swath, and the 60V FLEXVOLT platform stores far more energy than the 20V line. A 3Ah pack comes with the kit.
FLEXVOLT is DeWalt's dual-voltage battery system: the pack runs at 60V in FLEXVOLT tools and drops to 20V when used in 20V MAX tools. That makes it a good buy for someone who already owns 20V tools, since one pack can power both, though a trimmer that runs at 60V is a separate machine from the 20V models below.
The two speeds let you save charge on lawn grass and open up for thicker growth, and brushless efficiency stretches the pack further. It is a heavier tool, so expect it to tire you sooner than a 20V model. Keep the head clear of wrapped grass, use the line the head is rated for and store the battery indoors in winter.
