Ergonomics
The “D” shaped handle allows a nice padded grip for horizontal and vertical cutting applications and is positioned at a point along the shaft of the tool that when in use the tool has a nose down balance. This works well as the user is encouraged to rest the forearm on comfortable ripped pad located next to the battery housing. This positioning allows for a nice neutral hand position to manipulate the barrel grip with two paddle switches, one serving as a safety and the other a variable on-off. The Hi -Lo selector switch is positioned just below the thumb in this position and allows the user to easily select between the modes without setting the tool down.
Quiet and Low Vibration
Compared to traditional gas powered string trimmers this trimmer has two additional advantages. It is very quiet and produces little vibration. These two items may be minimized by some but can add up to very important factors with regards to safety and fatigue.
Runetime and Power
The DEWALT 20V String Trimmer is packaged with a 5.0Ah battery. At full charge this battery tested to deliver 26 minutes of continuous runtime on HI setting under no load. Runtime during actual operation will vary depending on the resistance of what is being cut. The beauty of the battery platform is the ability to quickly swap out a new battery and continue on your way.
The trimmer has a 13″ diameter cutting area that is serviced by a dual line bump feed that performs very smoothly in light to medium vegetation. I found myself running in Hi mode during almost all applications as the faster RPM performs better for all applications. The Lo setting can be enabled for longer runtime if that is a concern.
Maintenance and Care
Aside from routine cleaning the only regular maintenance required for the DEWALT 20V string trimmer will be to re-feed the string once its has been used. The DCST920 has a QuickLoad™ spool that allows the user to respool the trim line with relative ease. Pop the cover off, feed 25′ of line halfway through and wind it up in place. Gone are the days of requiring 4 hands for a simple task. During cutting the QuickLoad™ spool performs as a traditional bump feed style head that worked well in testing.

I see three different looking 20v models, o e silver motor, one with a yellow motor, and one with a black colored motor.
What are the difference s , they all seem to have the same specs.
Weed trimmer guard is too small. My pants are smothered with grass and weeds after using.
A little heavy as well.
Sure do miss my Craftsman!
Bought one of these from Tractor Supply. My son used it once. Next day, with a full battery, it wouldn’t turn on. Took it back and exchanged it. Second unit worked for a couple weeks, then the same issue. Too bad Dewalt isnt made in the USA anymore…
I hate this trimmer. Its heavy and doesn’t do a good job of trimming the edges of my lawn. I wish for my black and decker back but the batteries are no longer available. I may sell it and get a different brand. Very unhappy with it
