40V / ASIN B01GEW1AJC
Greenworks 2101602
A 12-inch edge path, auto-feed line, variable speed, and one 2.0Ah battery in a 40V tool family. Heavier than the WORX listing at 7.3 lb, and the kit includes only one battery for the handoff.
Home setup / lawn edges
Choose the trimmer by edge work and battery path.
Walk the property and count fence lines, bed edges, and tree rings before comparing voltage numbers. A lighter tool is easier around fragile borders. A wider cut path saves passes in open areas. Confirm guard, line feed, battery compatibility, and storage details before treating a kit as ready to use.
Best fit
Choose the trimmer around your regular edge work
Greenworks 2101602 fits households already on 40V with a 12-inch auto-feed head and a 2.0Ah kit. WORX WG163 GT 3.0 is lighter at 5.29 lb and adds a 90-degree pivot, edger wheel, telescoping shaft, and two 20V batteries when trim-and-edge control matters more than platform size.
Runtime shifts with grass condition, line diameter, battery age, and technique. Keep line, batteries, guard, and charger on one shelf.

20V / ASIN B018S68U40
WORX WG163 GT 3.0
Trim-and-edge work with a 90-degree pivot, support wheel, telescoping shaft, and two 20V batteries. The 20V system is compact, but platform choice matters if the yard already uses another battery family.
Trim routine
Store the trimmer ready for the next edge
- Walk the edge.Remove stones, toys, wire, and loose debris. Set a clear direction for the cut material.
- Check the guard.Use the supplied guard, line, handle, and eye protection. Confirm the battery is the exact platform for the tool.
- Trim with control.Keep the head at the intended angle. Use the edger wheel or pivot only as the manual describes.
- Reset the line.Clear wrapped grass, inspect the spool, and replace line with the diameter and feed method specified by the manufacturer.
- Store the kit.Return the battery, charger, guard, and spare line to one marked shelf. Charge the battery before the next planned job.
Decision checkpoints
Check line loading and edging controls
Cutting width matters, but how fast you reload line and switch to edging mode determines whether the tool stays in rotation. A wider cut path helps open areas and can feel clumsy near bark, siding, and garden borders.
A bare tool is a poor shortcut when the household does not already own the exact compatible battery and charger.
FAQ
Common questions
Does a higher voltage guarantee more runtime?
No. Runtime depends on battery capacity, load, line, grass, and technique. Compare the complete kit and the work area.
Is the WORX an edger?
It includes a 90-degree pivot and an edger wheel. Use the wheel and guard according to the manual for the cleanest edge.
How should I store spare line?
Keep the correct diameter line dry with the tool. A labeled spare prevents a mid-job search and avoids mixing incompatible line sizes.
