Abstract: A system for shearing bulk material includes a shearing cartridge with an input port and an output port. A first plurality of rotatable blades are disposed about a first shaft. A second plurality of rotatable blades is opposingly offset from the first plurality of rotatable blades.

Abstract: A system for shearing bulk material includes a shearing cartridge with an input port and an output port. A first plurality of rotatable blades are disposed about a first shaft, Each of the first plurality of rotatable blades includes a center aperture such that the first shaft extends through the center apertures of the first plurality of rotatable blades to selectively rotate each of the first plurality of rotatable blades simultaneously. A second plurality of rotatable blades is opposingly offset from the first plurality of rotatable blades. Each of the second plurality of rotatable blades includes a center aperture such that the second shaft extends through the center apertures of the second plurality of rotatable blades to selectively rotate each of the second plurality of rotatable blades in a direction opposite the first plurality of rotatable blades to shear and reduce the bulk material.

Abstract: A land plane to smooth and level any irregularities in the surface of an agricultural field. The land plane includes a main frame; a first wing frame attached to the first side of the main frame adjacent the front end thereof, a second wing frame attached to the second side of the main frame adjacent the rear end thereof; a V-shaped scrapper blade having an apex adjacent the front end of the main frame; a first transverse scrapper blade extending diagonally from the first wing frame across the main frame to the second wing frame and having a gap adjacent the second side of the main frame; and a second transverse scrapper blade means extending diagonally from the first wing frame across the main frame to the second wing frame, parallel to and spaced rearwardly from the first transverse scrapper blade.
