ABSTRACT:
A powered trimmer is provided which cuts in the manner of a scissors rather than a saw. A plurality of cutting assemblies is arranged along the length of a generally horizontal support bar. Each cutting assembly includes a vertical shaft mounted with respect to the support bar and passing through the center of each of a pair of pulleys mounted for independent rotation about the shaft. A blade is affixed to each pulley. Drive means including an arrangement of endless belts and offset pulleys are provided to counter-rotate the upper and lower pulleys in each pair, and thus their corresponding blades, for the desired scissors-like cutting effect.
