てあることを特徴とする収穫機の刈高さセンサ。 It is equipped with a grain culm lifting device, and is equipped with an ultrasonic transmitter and receiver attached to the reaping section, whose lower end is pivoted to the machine body so that it can be raised and lowered, and transmits ultrasonic waves from the transmitter toward the field surface. In the cutting height sensor of a harvester, the transmitter and the receiver are arranged on the already-cut side of the cutting section and the cutting height is detected by receiving reflected waves from the field surface at the receiver. The cutting height of the harvester is characterized in that the ultrasonic wave transmitting surface of the transmitter and the ultrasonic wave receiving surface of the receiver are mounted on the rear side of the grain culm pulling device with the ultrasonic wave transmitting surface of the transmitter and the ultrasonic wave receiving surface of the receiver facing downward toward the center side in the left-right direction of the harvester. Sa sensor.
