Abstract
A trimmer comprises two counter-rotating barrels side-by-side above one cutting reel. When viewed from the front, the left barrel rotates counter-clockwise while the right barrel rotates clockwise. Plant material in the barrels accumulates on the uphill side of each barrel, relative to its rotational direction, as the plant material traverses the rotating barrels. This configuration positions the uphill sides of both barrels proximate to the one reel. The barrel perforations are rifled to assist in moving the plant material through the barrels. Screw jacks are employed to tilt the trimmer; hardware facilitates use of two such trimmers in series.
