摘要

A harvester 10 configured to harvest crops while traveling in a field includes a self-machine position detection module 18 included in a machine body and operable to detect a self-machine position, a detection unit 40 included in the machine body and including detection modules 41-44 capable of detecting conditions of surrounding of the machine body, a map creation section 30 operable to create, based on the self-machine position, a map indicative of a position of a reaped land in the field where the crops have been reaped and a position of an un-reaped land in the field where the crops have not yet been reaped and an operational mode setting section 32 setting operational modes of the detection modules 41-44 respectively, based on the map and the self-machine position.
