Abstract
A discharge device includes a plurality of material conveying components, an adjustable shear ledge, and an adjustable shroud to convey materials from a container of a material spreader out onto an open area. The adjustable shear ledge includes at least one longitudinal mounting member such that the adjustable shear ledge may be translated towards or away from the plurality of material conveying components to maintain a predetermined gap distance. The adjustable shroud may also be pivotably connected to the adjustable shear ledge such that the adjustable shroud can be pivoted towards or away from the plurality of material conveying components. The adjustable shear ledge and the adjustable shroud may be moved accordingly to maintain a preferred gap distance and to maintain concentricity with a swing of the material conveying components in order to reduce wear on components and promote spread performance of the material spreader.
