Header clutch slip detection

An agricultural system, comprising:

• an agricultural harvester;
• a header coupled to the agricultural harvester, the header having a frame, a drive shaft, a plurality of row units, and a plurality of slip clutches, the drive shaft being configured to transmit power to each row unit, of the plurality of row units, through a separate slip clutch, of the plurality of slip clutches;
• a vibration sensor mounted on the frame of the header, configured to generate a sensor signal indicative of sensed vibrations;
• a signal processing system configured to convert the sensor signal to a digital signal, bandpass filter the digital signal to obtain a filtered signal, demodulate the filtered signal to obtain a demodulated signal, and transform the demodulated signal to a frequency domain signal;
• an input frequency calculation processor configured to obtain an input frequency indicative of a frequency at which vibrations occur on the frame of the header when a slip clutch, of the plurality of slip clutches, is slipping;
• a threshold comparison processor configured to compare a power of the frequency domain signal, within a range of the input frequency, to a threshold power value to obtain a comparison result;
• and
• a slip status output system configured to generate a slip status output indicative of whether the slip clutch, of the plurality of slip clutches, is slipping based on the comparison result.
