Claims (1)

[Scope of utility model registration request] In a combine harvester that is equipped with a stock side detection device and a tip detection device to detect the presence or absence of grain culms, and the handling depth is automatically controlled based on the detection result of the tip detection device, the grain culms transferred at the beginning of cutting are The detection signal of the tip detection device is disabled for t seconds immediately after detection by the source detection device, and forced shallow handling adjustment is performed. An automatic handling depth control device characterized by disabling the forced shallow handling adjustment when a grain root-side detection device detects grain culms at the time of feeding.
