Abstract: A flail type material spreader has an improved upper structure in which an upper side panel has a plurality of angularly related planar portions and terminates in an open recess which is substantially below the apex of the cylinder of rotation of the flails. A cover which also has a plurality of angularly related planar portions includes a pivot tube which is journalled in the recess on pivot bosses that are on upper end panels, and the free edge of the cover has parts defining an open pocket. A cover extension is pivotally mounted on the ends of the cover outside the pocket, and includes a structural tube below the pivotal mounting that projects into the pocket, with a body that also has several angularly related planar portions.
