Abstract
A trimmer having a first cutting blade and a second cutting blade. A first drive gear assembly cooperates with the cutting blades so that as the first drive gear assembly rotates around a first axis, the cutting blades are caused to reciprocatingly move in first and second paths to produce a cutting action. A second drive gear assembly has a second drive gear that has teeth in mesh with teeth on the first drive gear assembly. The second drive gear is rotatable around a second axis to cause the first drive gear assembly to be rotated in the first rotational direction. A powered drive assembly rotates the second drive gear around a second axis in the one rotational direction. The teeth on the first drive gear assembly are defined by a first bevel gear. The second gear is a bevel gear in mesh with the first bevel gear.
