The Greenworks 40V edger is the most balanced tool at this cap. It combines a brushless motor, an 8 inch steel blade, a curb wheel and a tool-free depth adjustment, and the 4.0Ah battery and charger are in the kit. For a household starting from scratch, it is the one that works immediately and grows with a platform.
The curb wheel is the feature that sets it apart from the unbranded 20V tools. It rides the pavement edge, which keeps the cut straight and limits blade contact with concrete, extending blade life. A brushless motor runs cooler in dense soil and uses the battery more efficiently, which is what makes a 4.0Ah pack last through a full yard.
Compared with the Milwaukee-compatible edger, it gives you a battery in the box and a branded warranty, while the other tool offers a wider blade and a more powerful rated motor if you already own packs. The 40V platform also powers other Greenworks tools, so the pack is a shared asset. Inspect the blade each season and store the battery partly charged.
