ンにおける刈高さ制御装置。[Scope of Utility Model Registration Claim] A combine harvester in which an actuator is operated based on the cutting height set by a cutting height target setter to control the raising and lowering of the cutting section to an appropriate height above the ground, comprising: A grain culm detection means is installed to detect the flow of the harvested grain culm in the reaping section, and during reaping work by automatic cutting height control, the cutting height target is set until the grain culm detection means detects the grain culm. The reaping section is controlled to be higher than the cutting height set by the setting device, and when the grain culm detection means detects the grain culm, the reaping section is controlled at the cutting height set by the cutting height target setting device. 1. A cutting height control device for a combine harvester, characterized in that a cutting section control means is installed to control the cutting height.
