PROBLEM TO BE SOLVED: To arrange a work-starting position for a next work passage by lifting up and down-controlling a working implement on turning a working machine at the end of furrow.SOLUTION: This controller is constituted by installing the working implement being lifted up and down relative to a traveling vehicle body, and a lifting up and down-controlling means for ascending the working implement in a prescribed first process in turning the traveling vehicle body and descending the working implement in a prescribed second process, and making the descending speed of the working implement by the lifting up and down controller as faster when the operation speed of the steering handle is fast. By the above constitution, since the lifting up and down speed of the working implement on turning becomes faster, when the operation speed of the steering handle is fast, it is possible to prevent a delay in the start of the work for the next working passage and transfer to the next working passage smoothly.COPYRIGHT: (C)2008,JPO&INPIT【課題】作業機の畔際での旋回時に作業装置を昇降制御するにあたり、次の作業行程の作業開始位置を揃える。【解決手段】走行車体に対して昇降する作業装置を設け、走行車体の旋回時における所定の第一の過程で作業装置を上昇させ、所定の第二の過程で作業装置を下降させる昇降制御手段を設ける。そして、ステアリングハンドルの操作スピードが速いときには、昇降制御手段の作業装置の下降速度を速くなるように構成する。前記構成によると、ステアリングハンドルの操作スピードが速いと、旋回時の作業装置の昇降速度が速くなるので、次の作業行程の作業開始遅れを防止し、次の作業行程への移行を円滑にすることができる。【選択図】図9
