Greenworks 60V 16 in Cordless String Trimmer, 4.0 Ah Battery

Why it's worth it

The Greenworks matches our top pick's 16-inch cutting width and adds an adjustable shoulder strap that shifts the load off your arms. It's attachment capable, shares a battery with more than 75 other 60V Greenworks tools, and carries a four-year warranty covering the tool and the pack.

On paper this lands close to the EGO: 16-inch swath, brushless motor, a 4.0Ah battery and charger in the box. The difference is the head. Load N' Go threads a fresh length of line without dismantling the spool, which is genuinely quick, but it doesn't sense wear the way Line IQ does. Expect a little more fiddling mid-job on tall, wet grass.

The shoulder strap is the underrated part. A 16-inch head hanging off one arm gets heavy by the third pass down a long driveway. Clipping into the included strap moves that weight onto your torso, and you'll feel it most on slopes and awkward stretches where you're already bracing. If you've got a half acre or a lot of fence line, take the strap seriously.
