Abstract:
In a crop residue spreader including an element disposed in a housing and rotatable in a predetermined direction about an axis for driving a flow of crop residue through a discharge opening of the housing located at a predetermined angular position around the axis, an improvement comprising:a flow guide including at least two tiers having inlet ends disposed in at least generally axially side by side relation adjacent to the discharge opening in position for directing portions of the flow of crop residue in generally the predetermined direction radially outwardly and away from the opening, respectively, each of the tiers having a curved surface connected to the inlet end thereof and extending generally in the predetermined direction radially outwardly and away from the discharge opening to a discharge end spaced radially outwardly from the spreader for directing the respective portion of the flow of the crop residue radially outwardly away from the spreader, the curved surfaces and discharge ends of the tiers being vertically offset one relative to the other such that the portions of the flow of the crop residue will follow vertically different flow paths away from the spreader, further comprising an element pivotally connecting the flow guide to the spreader for pivotal movement about a pivotal axis at least generally parallel to the axis of the spreader to allow moving the discharge ends of the tiers through a range of positions different radial distances from the axis of the spreader.
