ABSTRACT:
An implement has a row of tined motors that work a broad path of soil. Immediately in front of the rotors is a soil displacing elongated bar that is held to penetrate and raise a shallow layer of soil which is thereafter deposited immediately in front of the working tines. The bar extends parallel to the row of rotors and has a flat bottom that slightly compresses the ground from which the layer of soil is being displaced. The bar can be raised or lowered on supports interconnected to the frame. In front of the bar, a V-shaped guide can be connected to smooth the soil engaged by wheels of the prime mover. A rear roller can be positioned to further level the layer of soil that has been worked by the counter rotating rotors so that a seed bed can be finally prepared in one pass.
