Here is my situation. Two years ago I got tired of dealing with my troybilt 4 stroke gas trimmer. Plus I'm left handed and it always threw everything at my legs. I gave the trimmer to a co-worker. So I bought the dewalt 20v trimmer since I have DeWalt 20v tools. The 20v trimmer works great for grass trimming around the house. Plus it don't throw grass at my legs. Now since I moved out in the country less than a year ago I need a more powerful trimmer for tall weeds in the ditch.
I like the idea of going with battery tools so I don't have to deal with all the extra maintenance with gas powered equipment. Since I moved out in the country I bought the dewalt 40v chainsaw and 40v blower. I can get the dewalt 40v trimmer without a battery for $199. But I'm worried about it still won't be powerful enough power as a gas trimmer to handle tall weeds. I did a lot of research on gas trimmers. So if I decided to go that route it will be the Echo srm-225 two stroke.
