Abstract
An apparatus for processing plant stalks after harvesting includes a frame structure supported from a ground surface for translatory movement at a predetermined rate and in a predetermined direction along a row of plant stalks and at least one pair of pneumatic tires having their peripheries in pressure contact with each other and thus forming a nip for receiving plant stalks therein. The rotating pneumatic tires are disposed at a predetermined angle relative to the ground surface, and the pair of pneumatic tires being rotated at a predetermined peripheral speed. The predetermined speed of the pneumatic tires is determined by and less than the rate of movement of the frame structure. The nip of the pneumatic tires thereby grasps the plant stalks for a sufficient period of time and for a sufficient distance of movement of the frame structure such that the plant stalks are pulled from the ground surface with their roots substantially attached thereto.
