Abstract: An apparatus for facilitating processing of plant material is disclosed. The apparatus includes a base, a cutter disc rotatably coupled to the base such that the cutter disc is configured to rotate about an axis of rotation relative to the base, the cutter disc having an upper side including a plurality of radially spaced teeth, each of the plurality of teeth configured to travel on a respective cutting path to engage and shear the plant material when the cutter disc rotates. The apparatus includes a shearing governor rigidly coupled to the base, the shearing governor including one or more cutting edges, each of the one or more cutting edges extending adjacent to the cutting paths of at least two of the plurality of teeth and configured to shear the plant material when the cutter disc rotates. Other systems and apparatuses are disclosed.
