Claims

[Scope of utility model registration request]

In the row crop header in which each of the reaping units E can be raised and lowered, an actuator 50 is interposed between the main frame 20 and the reaping frame 27 to enable the reaping unit E to be raised and lowered, and the area near the cutting blade 41 provided on the reaping frame 27 is A mowing height control device for a row crop header, characterized in that a sensor arm 42 is projected downward to detect the height, and an actuator 50 is controlled to expand and contract by rotating the sensor arm 42.
