PROBLEM TO BE SOLVED: To provide a working vehicle in which stable work traveling can be secured by preventing dashing when a working device comes down automatically along with returning to straight traveling after turning of a machine body.SOLUTION: A working vehicle is characterized as follows: a working device for performing a field work at a work height position is included so as to be lifted/lowered in a range up to a standby height position the working device is constituted so as to be automatically lifted/lowered in correspondence with the turning operation of a machine body a deceleration control switch for applying deceleration control to slow down immediately before grounding is provided about a lowering motion step of the working device automatic lowering control in which the working device is automatically lowered to the work height position by the returning to straight traveling after the turning of the machine body is constituted in a possible manner and the deceleration control can automatically be applied when the automatic lowering control is applied. Thereby, the dashing when the working device comes down automatically is prevented, and the stable work traveling is made possible.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】機体旋回後の直進走行復帰とともに作業装置が自動下降する際に、ダッシングを防止して安定作業走行を確保することができる作業車両を提供する。【解決手段】作業車両は、作業高さ位置で圃場作業を行う作業装置を待機高さ位置までの範囲で昇降可能に備え、機体旋回操作と対応して前記作業装置を自動昇降可能に構成され、前記作業装置の下降動作工程について、接地直前から減速するデセラ制御を適用するためのデセラ制御スイッチを設け、前記機体旋回後の直進走行復帰により、前記作業装置を作業高さ位置まで自動的に下降させる自動下降制御を可能に構成し、前記自動下降制御が適用されると前記デセラ制御を自動的に適用可能に構成することにより、作業装置が自動下降する際のダッシングを防止して安定作業走行を可能とするものである。【選択図】図1
