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 elongate fingers, the fingers having proximal ends located adjacent to an upstream end of the discharge opening relative to a direction of the flow and extending from the proximal ends generally circumferentially to the path of the flow to distal ends located spaced outwardly from the housing and the discharge opening, adjacent ones of the fingers defining spaces therebetween such that portions of the flow will pass through the spaces so as to be spread onto areas of an agricultural field adjacent to the spreader and other portions of the flow will be guided along the fingers so as to be propelled from the spreader and spread over areas of the field a desired distance from the spreader; and a shield positioned in covering relation to less than an entire portion of the space between at least two adjacent ones of the fingers adjacent the proximal ends thereof for limiting flow through the portion of the space.
