PROBLEM TO BE SOLVED: To allow a first work vehicle side to easily grasp dispersion position information of a second work vehicle side, and prevent duplication of spraying and occurrence of an area where chemical is not sprayed, in a work state in which plural spraying work vehicles enter mutually in a farm field, and perform spraying work simultaneously from both ends of the farm field.SOLUTION: Respective spraying work vehicles can detect position information by a GPS satellite (20), in a spraying work state in which at least plural spraying work vehicles (1A), (1B) perform chemical spraying work from both ends of the farm field. A pest controller (18) of the at least first work vehicle (1A) on one side of driving, comprises display means (22) for displaying position information of a spraying range of the second work vehicle (1B) on the other side.COPYRIGHT: (C)2016,JPO&INPIT【課題】本発明の課題は、複数の散布作業車を相互に圃場に乗り入れ、圃場の両端から同時に散布作業を行う作業形態において、第1作業車側が第2作業車の散布位置情報を容易に把握できるようにし、散布の重複や、無散布区域の防止を図ることにある。【解決手段】本発明は、少なくとも複数の散布作業車(1A),(1B)によって圃場の両端から薬液の散布作業を行う散布作業形態において、夫々の散布作業車はGPS衛生(20)による位置情報の検出が可能で、少なくとも運転する一方側の第1作業車(1A)の防除コントローラ(18)には、他方側の第2作業車(1B)による散布範囲の位置情報を表示できる表示手段(22)を設ける。【選択図】図6
