All depends on the task. I have a John Deere lawn tractor, E170, that handles the yard, including leaf removal. I have a Milwaukee leaf blower that is just used to blow leaves out of the bushes and away from the house. The JD takes care of them afterwards. I have a battery operated string trimmer that is quiet and doesn’t produce any smell. I don’t have that much trimming with a little over a half acre, so that will never be gas. I am also looking to purchase a Milwaukee battery operated bush trimmer in the next few years as well as a battery operated tree trimmer chainsaw. I will likely always have my Husqvarna gas powered chainsaw for any trees in the back or tree branches that are more that a few inches in diameter. I will also be sticking with a gas powered snowblower as my area can get 12” of snow in a single storm, sometimes even over 24” on a rare nor’easter.
