With a shaft that can be easily stored in three parts, it safely cuts long grass and reaches areas that your lawn mower cannot. Simply turn it on, and the line will be continuously fed to ensure that the trimmer is always cutting. It allows you to protect the bark of trees by resting it against the trunk while trimming, cutting grass at the edge of a flower bed without damaging flowers and shrubs. 24 V 2 Ah or 4 Ah battery - this is a tool package that is delivered without a battery. If you already own a Greenworks 24 V tool, you can use the same battery to save space and costs.
