well I have a small yard to take care of, i bought a ryobi 40 volt string trimmer/ blower. I get 15 minutes run time with the trimmer... 4 amp battery, plus it heavy,, but really like the blower. for leaf cleaning (20 minutes run time on blower... wish i went for the toro 60 volt stuff. ps I've never had any gas trimmers, just the 120 volt corded ones. just sharing my homeowner experience with the ryobi 40 volt. ps just bought the ryobi 40v hedge pole trimmer, I like it, heavy but no cord , and the head adjust in 4 spots/angles so i can trim into round shapes on my hedges .
