Abstract

The invention is directed to a cutter apparatus having a stationary blade and a rotating blade. The rotating blade is driven in rotation by a drive motor. The rotating motion causes the knife and blade to slide relative and over each other in a manner of scissors. The blade and knife each include a plurality of cutting edges with the cutting edges of the knife and blade being so arranged that they run toward each other at an angle opening outwardly. The cutting edges of the stationary blade are formed on radially extending fingers arranged in a star-shaped configuration which facilitates the manipulation of the cutter apparatus and improves the cutting quality thereof. The cutting apparatus is suitable for all kinds of vegetation including leaves and grass blades.
