PROBLEM TO BE SOLVED: To provide a rough plowing implement which can control the movements of soil inverted on a rough plowing work using the rough plowing implement within the width of the implement, and can thereby improve the efficiency of the work. SOLUTION: The rough plowing implement is equipped with a digging, inverting, throwing unit, in which metal plate-like covers are disposed in the end portion of the implement to control the movements of soil within the width of the implement, thereby reducing the subsequent various works such as a land-grading work to improve the efficiency of the works, because soil inverted and thrown with a conventional digging, inverting, throwing unit is moved outside the width of the implement.
