PROBLEM TO BE SOLVED: To hardly cause the inconvenience of damaging a harvesting part due to its contact with other articles during moving travel by configuring such that the harvesting part is located on the traveling machine body side rather than a second working position during moving travel.SOLUTION: A harvesting part sliding operation structure of a combine harvester includes a slide operating mechanism 44 for slidingly displacing a harvesting part in a lateral direction a slide control part 50B for controlling the operation of the slide operating mechanism 44 a first output part C for outputting information that permits identification on whether the position of the harvesting part is a second working position set into a state where one lateral end side of the harvesting part projects to the lateral outside of a traveling machine body and a second output part F for outputting information that permits prediction of a shift into a moving travel state. When predicting the shift into the moving travel state based on the information output from the second output part F in a state of determining that the position of the harvesting part is the second working position based on the information output from the first output part C, the slide control part 50B controls the operation of the slide operating mechanism 44 to displace the harvesting part to the traveling machine body side rather than the second working position.COPYRIGHT: (C)2014,JPO&INPIT【課題】移動走行時には刈取部が第2作業位置よりも走行機体側に位置するように構成して、移動走行中に刈取部が他物に接触して損傷する不都合を招き難くする。【解決手段】刈取部を横方向にスライド変位させるスライド操作機構44と、スライド操作機構44の作動を制御するスライド制御部50Bと、刈取部の位置が刈取部の左右一端側が走行機体の横外側に張り出す状態に設定した第2作業位置か否かの判別を可能にする情報を出力する第1出力部Cと、移動走行状態への移行の予測を可能にする情報を出力する第2出力部Fとを備え、スライド制御部50Bが、第1出力部Cからの出力情報に基づいて刈取部の位置が第2作業位置であると判断した状態において、第2出力部Fからの出力情報に基づいて移動走行状態への移行を予測した場合には、スライド操作機構44の作動を制御して、刈取部を第2作業位置よりも走行機体側に変位させるように構成した。【選択図】図9
