Agricultural machine

An agricultural machine comprising:

• a vehicle body including a front wheel and a rear wheel;
• an obstacle detector to detect an obstacle;
• a position changer to change a position of the obstacle detector between a detection position to detect an obstacle and an evacuation position to evacuate toward the vehicle body from the detection position;
• and
• a controller to control automatic traveling of the vehicle body;
• wherein
• the position changer is configured to switch between a detection posture to locate the obstacle detector in the detection position and an evacuation posture to locate the obstacle detector in the evacuation position;
• the position changer includes a posture detector to detect whether the position changer is in the detection posture or in the evacuation posture;
• the controller receives detection information from the posture detector indicating whether the obstacle detector is in the detection position or in the evacuation position, and controls the automatic traveling of the vehicle body based on the detection information;
• the position changer includes a first support arm fixed to the vehicle body, and a second support arm rotatably supported by the first support arm;
• the obstacle detector includes a first obstacle detector provided on a second end of the second support arm, and a second obstacle detector provided on an intermediate portion of the second support arm between the second end and a first end of the second arm;
• and
• the second support arm is rotatable with respect to the first support arm between a first position to locate the first obstacle detector and the second obstacle detector in the detection position to detect an obstacle, and a second position to locate the first obstacle detector and the second obstacle detector in the evacuation position to evacuate the first obstacle detector and the second obstacle detector toward the vehicle body from the detection position.
