Abstract

A garden chopping/shredding apparatus has a frame provided with an upwardly open intake hopper on the frame having a lower end in which is in turn provided a generally horizontal blade plate and formed about the axis with a plurality of angularly spaced apertures. Respective flat blades carried on the blade plate have cutting edges above the apertures and a plurality of prechopping blades carried on the blade plate projecting upward therefrom have cutting edges inclined upward and inward toward the axis. The drive rotates the plate and the blades in a predetermined direction about the axis so as to define with the cutting edges of the flat blades a generally planar and circular orbit perpendicular to the axis and having an inner periphery offset radially outward from the axis and to define with the cutting edges of the chopping blades an upwardly tapered frustoconical orbit centered on the axis and having a small-diameter upper end and a large-diameter lower end. A deflector or abutment plate fixed against rotation in the lower end of the hopper has a panel with a lower cutting edge juxtaposed with the orbit of the flat blades and an inner edge juxtaposed with the orbit of the prechopping blades. This panel forms an acute angle open backward into the direction of rotation with the orbit of the flat blades and its lower cutting edge extends generally tangentially to a circle centered on the axis and having a greater diameter than the inner periphery of the orbit of the flat blades.
