Automatic traveling method, work vehicle, and automatic traveling system

Abstract

A combine harvester includes a control device and a portable terminal. The control device functions as an automatic traveling control part for controlling the combine harvester to perform automatic traveling on the basis of an automatic traveling route comprising a plurality of set straight traveling routes and a plurality of set turning routes, and as a discharge traveling control part for controlling the combine harvester to perform discharge traveling from a predetermined transition position on the automatic traveling route to a discharge position. The portable terminal includes the control device, and the control device functions as the transition position change part for changing, as the transition position, the first transition position that is set on the basis of the storage amount of harvested grain, to the new second transition position in response to the operation of the discharge transition operation part such as the discharge advance button and the discharge postpone button.
