Abstract: A lightweight hand held vegetation trimmer powered by an onboard battery, or alternatively available in a version powered by 120 volt mains power. A battery pack powers an electric motor to generate a rotary output and a cutting line adapted to be rotably driven by a line support structure, all enclosed within a round or elliptical shaped hood. By introducing an upwards facing impeller driven by the same electric motor within the internal chamber under the hood structure, the trimmer is floated on a cushion of air, to carry the weight of the cutting head to reduce operator fatigue and to maintain a continuously horizontal cutting position for the cutting element.
