        Great tool for grass trimming

          • Grass trimming

          Since I already have two GMax batteries this was a great deal as tool only. It would deserve 5 stars except the automatic line feeder is not working well.

              Best Uses

                We have a 1 1/2 yard property and combined with a total of 3 batteries this tool gets the job done in in one round of charges. The string it comes with can't withstand the power of the tools. I replaced with a thicker one I had from a gas weeder and it works like a charm chopping down even thick weeds. The power of this tool is really comparable to the one of gas weeders with the plus of being eco friendly and zero maintenance. Highly recommended

                  • Q:

                    is it true that the greenworks g-max trimmer 40 v battery is not interchangeable with other greenworks 40 v battery products?

                      Yes, these two batteries are not interchangeable. A GMax tool must use a GMax battery. Also, same for the regular Greenworks 40V battery.
