とを特徴とする自走農機の刈高さ制御装置。1. In a mowing height control device for a self-propelled agricultural machine that is connected to a grain culm detection sensor of an automatic steering control device attached to a preprocessing section and connected to a steering clutch, a wave generation/reception device and a wave generation/reception device A cutting height detection sensor having a wave control device and the grain culm detection sensor are installed in the preprocessing section, and the wave generation and reception device includes an input interface and an output device connected to the input interface. The wave control device is electrically connected to the grain culm sensing sensor so as to weaken the oscillation vibration in the grain culm sensing state. Mowing height control device for self-propelled agricultural machinery.
