PROBLEM TO BE SOLVED: To provide a working vehicle capable of efficiently executing farm field management.SOLUTION: A working vehicle includes a camera 6 for taking an image of a plant growing in a farm field, a sowing device 5 for sowing seeds in the farm field, and a control device C. The control device C includes a growth state determination part 10 for determining a growth state of lawn in the farm field based on a result of imaging by the camera 6, and a sowing ordering part 12 for ordering the sowing device 5 to sow the seeds based on a result of the determination by the growth state determination part 10. The working vehicle further includes a vehicle speed sensor 7 for detecting a vehicle speed. The camera 6 is installed in a front part of a machine body, and the sowing device 5 is installed in a rear part of the machine body. The control device C includes an estimated passage time calculation part 11 for calculating estimated passage time when the sowing device 5 passes on the plant imaged by the camera 6 based on a detection value of the vehicle speed sensor 7. The sowing ordering part 12 orders the sowing device 5 to execute sowing of the seeds when the estimated passage time has elapsed.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】圃場管理を効率的に行うことが可能な作業車を提供する。【解決手段】圃場に生育する植物を撮像するカメラ６と、圃場に種を播く播種装置５と、制御装置Ｃは、カメラ６の撮像結果に基づいて、圃場の芝の生育状態を判定する生育状態判定部１０と、生育状態判定部１０の判定結果に基づいて、播種装置５に播種の実行を指令する播種指令部１２とを備える。さらに車速を検出する車速センサ７を備え、カメラ６は機体の前部に配置され、播種装置５は機体の後部に配置され、制御装置Ｃは車速センサ７の検出値に基づいて、カメラ６が撮像した植物上を播種装置５が通過する通過予想時間を演算する通過予想時間演算部１１を有し、播種指令部１２は通過予想時間が経過した時に播種装置５に播種の実行を指令する。【選択図】図２
