Claims

[Scope of Claim for Utility Model Registration] (1) A non-contact sensor that includes a reaping section on the body and that transmits waves such as ultrasonic waves and receives reflected waves of the waves to detect the distance to obstacles, etc. In the harvester, the non-contact sensor is configured to be movable so as to be able to detect different directions, and a sensitivity switching means is installed to switch the sensitivity of the sensor as the direction is switched. Distance detection device in harvester. (2) the non-contact type sensor is switched toward the field scene as a cutting height sensor during reaping work;
The distance detection device for a harvester according to claim 1, which is configured to be switched to the front or side of the machine body as a front or side sensor during rounding work.
