Overview
A pivoting head lets this Greenworks string trimmer switch between trimming and edging with one button, and an auto feed line advances without bumping. A telescoping shaft adjusts for different users, and the kit includes a battery and charger.
Switching modes without tools, a quiet motor and an adjustable shaft suit beginners and shared use, and the battery works with a wide range of other Greenworks 24V tools. Battery life is stated as a short session. The shaft range is given in inches, which looks like a mistake, and the weight is stated two ways.
Who it's for
Homeowners with a small lawn, beginners and shared households will use the pivot, the one-button edging switch and the adjustable shaft. Anyone trimming big areas or thick growth should look at higher capacity tools and more batteries.

- Trimmer and edger in one tool
- Pivoting head for uneven ground
- Auto feed line
- Battery shared with other 24V tools
- Short stated battery life

Performance notes
A motor spins the line at the listed speed, and the auto feed advances new line as it wears. The pivoting head turns the tool from a trimmer to an edger, and the shaft adjusts for height. A single small battery limits the area covered per charge.
