An earth mover includes a scraper bowl with an arcuate bottom wall and a pair of side walls attached to a frame. An ejector panel is supported by a pair of pivoting support links, each of which is pivotally attached to the frame above the upper limit of the bowl side walls and each of which is also pivotally attached to the ejector panel. The ejector panel is selectively movable through a shallow arc which mirrors the shape of the of the bowl bottom wall while the pair of support links support the ejector panel in a substantially upright position as it moves from a forward, ejecting position to a retracted position in which the ejector panel forms a rearward wall for the scraper bowl.
