Abstract
A rotary drum trimmer device with one or more dynamic shear bands. The trimming device receives plant material through a hollow interior of a generally cylindrical drum having a plurality of perforations extending through its sidewall. The perforated drum rotates to tumble plant material within its interior thereby exposing portions of the plant material through perforations in the drum sidewall. Disposed against an outside surface of the rotating perforated drum are one or more shear bands. Rotary moment of the drum relative to the shear bans(s) severs plant material extending through both elements. The shear band is configured to move (e.g., reciprocally) relative to the perforated drum while the drum rotates to improve trimming.
