PROBLEM TO BE SOLVED: To provide an agricultural working machine easily turning a chair part.SOLUTION: This agricultural working machine comprises a travelling machine body 2 travelling in a field, and the travelling machine body 2 is provided with a chair 21 for a worker. The chair 21 has a chair part 23 to be raised and lowered in relation to the travelling machine body 2 and to be turned around the center axis X of turn in the vertical direction in relation to the travelling machine body 2. The travelling machine body 2 is provided with a lower engagement part 24, and the char part 23 is provided with an upper engagement part 25 to be engaged with/disengaged from the lower engagement part 24. In the state of engaging the lower engagement part 24 with the upper engagement part 25, the chair part 23 is not turned in relation to the travelling machine body 2. When engagement of the lower engagement part 24 with the upper engagement part 25 is released by raising the chair part 23, the chair part 23 can be turned in relation to the traveling machine body 2.COPYRIGHT: (C)2008,JPO&INPIT【課題】椅子部を容易に回動できる農作業機を提供する。【解決手段】農作業機は、圃場を走行する走行機体2を備え、この走行機体2には作業者が座る椅子体21を設ける。椅子体21は、走行機体2に対して昇降し走行機体2に対して上下方向の回動中心軸線Xを中心として回動する椅子部23を有する。走行機体2には下側係合部24を設け、椅子部23には下側係合部24に対して係脱する上側係合部25を設ける。下側係合部24と上側係合部25とが互いに係合した状態時には、椅子部23は走行機体2に対して回動しない。椅子部23を持ち上げて下側係合部24と上側係合部25との係合を解除すれば、椅子部23を走行機体2に対して回動させることができる。【選択図】図2
