PROBLEM TO BE SOLVED: To provide a working machine capable of saving labor for maintenance work of an agricultural material supply device. SOLUTION: An agricultural material supply device 16 is connected to a storage unit 1, a feeding unit 2, a feeding unit 2, and a first discharging unit 7 and a storage unit that discharges the agricultural material delivered by the feeding unit 2. The agricultural material supply device 16 has a second discharge unit 8 which is connected to 1 and discharges agricultural materials from the storage unit 1 without passing through the feeding unit 2, and the agricultural material supply device 16 has a swing shaft along the left-right direction of the machine body. By swinging around the core P, the posture can be changed between the standing posture and the lying posture. When the agricultural material supply device 16 is in the standing posture, the feeding portion 2 is the storage portion 1. It is located downward, the first discharge unit 7 extends from the feeding unit 2 to the rear side, and the second discharge unit 8 extends from the storage unit 1 to the front side, and swings from the standing posture. A posture maintaining mechanism 3 for maintaining the posture of the agricultural material supply device 16 in an intermediate posture in which the angle is smaller than the lying posture is provided.
