Abstract:
1. A soil spreading scraper device comprising: a frame supported for movement along the ground in a forward working direction; an impeller member supported on the frame for rotation about an impeller axis within a plane of rotation lying generally perpendicularly to the impeller axis, the plane of rotation extending generally upward and rearward; a cutting blade supported on the frame forwardly and downwardly relative the impeller member and arranged to cut a top layer of soil from the ground as the frame is displaced in the forward working direction; a kicker supported on the frame for rotation about a kicker axis spanning above the cutting blade transversely to the forward working direction and arranged to propel soil cut by the cutting blade generally rearward onto the impeller member; the impeller member comprising a plurality of impeller blades arranged to spread soil deposited on the impeller member generally radially outward from the impeller axis as the impeller member is rotated; an impeller gearbox comprising an input shaft and an output shaft geared to rotate with rotation of the input shaft; the impeller gearbox being oriented such that an output axis of the impeller gearbox is coaxial with the impeller axis and the output shaft is parallel to the impeller axis; the output shaft of the impeller gearbox being directly coupled to the impeller member such that the output shaft of the impeller gearbox and the impeller are fixed relative to one another for rotation together about the impeller axis without any variable angle connectors being coupled between the impeller gearbox and the impeller member; and a secondary gearbox offset laterally from the impeller gearbox in relation to the forward working direction;
