<P>PROBLEM TO BE SOLVED: To provide an agricultural working machine configured to prevent a ridger from unexpectedly ridging a field and damaging the field. Ž<P>SOLUTION: When a steering wheel angle detecting sensor 109 detects steering operation of a steering wheel 14 to a predetermined value, a control device 110 is operated such that a ridger hydraulic cylinder 89 raises the ridger (groover) 95 positioned at a ridging position to a non-ridging position, a seeder hydraulic cylinder 46 is operated to raise a seeder 82 positioned at a working position to a non-working position, and when it is determined that turning almost ends or has ended, the control device is operated such that the seeder 82 is firstly lowered to the working position, and then the ridger 95 is lowered to the ridging position. Therefore, the ridger 95 is raised prior to the seeder 82, and the raised ridger 95 is lowered on the field posterior to the seeder 82, so that the agricultural working machine can prevent the field and crops from being damaged.
