Abstract
An extractor is disclosed for a sugarcane harvester that chops stalks of sugarcane into billets. The extractor comprises a housing, a fan positioned within the housing and comprising fan blades mounted for rotation in a rotational path about an axis of rotation to induce a flow of air to extract leaf material from billets produced by the sugarcane harvester, and a leaf shredder positioned within the housing and comprising shredding knives fixed against rotation about the axis of rotation, the shredding knives offset axially from the fan blades relative to the axis of rotation in proximity to the rotational path of the fan blades such that the fan blades and the shredding knives cooperate to shred leaf material by shearing action as the fan blades rotate past the shredding knives about the axis of rotation.
