Patent

CA 2619670

A soil spreading scraper device comprises a cutting blade for cutting a top layer of soil from the ground, a kicker for throwing the cut soil rearward from the cutting blade, and an impeller member rotatable within a plane of rotation extending upward and rearward from the cutting blade for capturing the soil thrown by the kicker and spreading the cut soil generally radially outward relative to an axis of rotation of the impeller. A gearbox which receives power from a power takeoff of a towing vehicle directly drives the rotation of the impeller member in the preferred embodiment. The blades of the impeller members may include recessed portions adjacent the impeller axis in some embodiments to encourage soil being received in the impeller member even at higher rates of rotation, for example in the range of 250 to 320 RPM.
