PROBLEM TO BE SOLVED: To promote efficiency of grass-collecting processing of mowed grass by an automatic traveling mowing device that can widely perform mowing work in an unmanned state.SOLUTION: A grass-collecting work machine includes a grass-collecting working unit 33 for grass-collecting of the mowed grass on the ground and a receiving hopper 32 for receiving the mowed grass collected, in a frame 31 capable of traveling. A grass-collecting work machine controller 37 includes grass-collecting path input means. The traveling of the grass-collecting work machine is configured to be controlled by this grass-collecting path input means. Also, the grass-collecting path input means inputs the mowed grass imaging data on the ground by a camera 38, and enables communication between a controller 17 of an automatic traveling mowing device 1 and the grass-collecting work machine controller 37. The grass-collecting path of the grass-collecting path input means is configured along the mowing path.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2020,JPO&INPIT【課題】無人で広範囲に草刈作業ができる自動走行草刈装置によって刈り取られた刈草の集草処理の効率化を図る。【解決手段】走行可能なフレーム31に、地面の刈草を集草する集草作業部33と集草された刈草を収容する収容ホッパ32を備えた集草作業機において、集草作業機コントローラ37に集草経路入力手段を備え、この集草経路入力手段によって集草作業機の走行を制御する構成とした。また、集草経路入力手段は、カメラ38による地面の刈草撮像データを入力するか、自動走行草刈装置1のコントローラ17と集草作業機コントローラ37とを通信可能とし、集草経路入力手段の集草経路を草刈経路に沿う構成とする。【選択図】図7
