PROBLEM TO BE SOLVED: To provide a working machine in which measures are taken to prevent the working machine from advancing even when gripping is cancelled after both side clutch levers are gripped simultaneously.SOLUTION: In the case of YES in ST14, a left lever switch and a right lever switch are both on, and the step proceeds to ST17. In ST17, a control unit checks whether or not an on-time of the right and left lever switches has continued for a predetermined time (e.g., 1.0 sec). If the on-time is less than the predetermined time, it is considered to be an erroneous operation due to an operators inclination, and the step returns to a step before ST11. If it is confirmed in ST17 that the on-time of the right and left lever switches has continued for the predetermined time, the control unit brings a travelling clutch into a disengaged state, and stops the working machine from travelling, on the basis of this information (third information) (ST18). The control unit brings an operation clutch into a disengaged state and stops the rotation of an auger and a blower (ST19).SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】両方のサイドクラッチレバーを同時に握った後に、握りを解消した場合であっても、作業機が前進しないようにする対策が講じられている作業機を提供する。【解決手段】ST14でYESであれば、左のレバースイッチと右のレバースイッチが共にオンであり、ST17へ進む。ST17では、左右のレバースイッチのオン時間が、所定時間(例えば1.0秒)継続したか否かを調べる。所定時間未満であれば、作業者の癖に基づく誤操作と見なし、ST11の前に戻る。ST17で、左右のレバースイッチのオン時間が、所定時間継続したことが確認されれば、この情報(第3情報)に基づいて、制御部は、走行クラッチを切断状態にして作業機の走行を停止し(ST18)、作業クラッチを切断状態にしてオーガー及びブロアの回転を止める(ST19)。【選択図】図9
