A working machine includes a controller device to set an allowable-stroke range of the arm cylinder moving the arm toward the boom depending on a turn position of the boom such that a shortest trajectory distance that is a shortest distance between the boom cylinder and a turn trajectory of the tip end portion of the bucket is kept at a predetermined value even when the turn position of the boom changes, in a case where the boom is turned in a direction separating from a boom reference position.
