Abstract: In an agricultural machine, a route creator creates a planned traveling route for a traveling vehicle body in a work area where a working device works using a material. An area setter sets, outside the work area, a replenishment area to replenish the material. A charge amount acquirer acquires a charge amount of the material. A remaining amount calculator calculates a remaining amount of the material based on the charge amount acquired and a material consumption of the material consumed by the work. A position setter sets a replenishment position to replenish the material in the replenishment area set by the area setter based on the remaining amount calculated by the remaining amount calculator. A position changer changes the replenishment position when a change reception switch receives change of the replenishment position. A display displays the changed replenishment position.

Abstract: An agricultural machine includes a swath information acquiring module, a first determining module to determine a traveling path of an automatic operation based on a position of a swath, a setting module to set a work continuation width based on the traveling path, a second determining module to determine, when there is a manual operation by a worker during the automatic operation, whether the agricultural machine during the manual operation is within the work continuation width, and an executing module to execute the automatic operation. The executing module restores the agricultural machine to the traveling path after a termination of the manual operation and continues the automatic operation when the agricultural machine is within the work continuation width, and cancels the automatic operation when the agricultural machine is determined to be not within the work continuation width.

Abstract: A traveling vehicle includes a controller to control a posture of a work machine via a connector. The controller observes whether a farm field surface on which the traveling vehicle travels and the work machine maintain a predetermined positional relationship therebetween, and controls the posture of the work machine when a positional relationship between the farm field surface and the work machine changes from the predetermined positional relationship, so that the positional relationship thus changed is reset to the predetermined positional relationship.
