See full text

A wheel mounted string trimmer having a wheel support with a pair of wheels mounted on opposite sides thereof and handle bars extending rearwardly from the support. An elongated tube housing a drive shaft, is adjustably fastened to the wheel support to extend forwardly to a string trimmer head which is coupled to the drive shaft by a gear transmission whose housing is rotatably mounted on the front end of the tube. The trimmer head has a shield fixed to the transmission housing to be adjustable therewith about the tube housing. A yoke bracket is fixed to the shield while being mounted about the tube housing to be adjustable about the axis of the latter to orient the shield and head in the desired position for trimming. A gasoline engine, mounted to the rear of the tube housing, drives the head through the drive shaft and transmission.
