摘要： A control system of a loading machine, having working equipment including a bucket, includes a control device. The control device detects a first surface of an excavated object excavated by the bucket during excavation work, calculates an under-excavation load angle indicating an angle of the first surface with respect to the horizontal plane on the basis of detection data of the first surface, and estimates the weight of the excavated object on the basis of the under-excavation load angle.
