PURPOSE:To stabilize the ground working travel by controlling the car speed according to behavior of a ground working device. CONSTITUTION:A working machine is equipped with a sensing means (PM2) for sensing the height of a ground working device from a machine body and the second deceleration controlling means (B) for automatically decelerating an electrically controlling type speed changer 5 interposingly installed in a travel transmission system based on the sensed results of the aforementioned sensing means (PM2) regardless of the set speed. |
