Abstract

A method for state detection of a cutting device for agricultural crop is described. The cutting device is formed with a cutting tool set into rotation with respect to a shear bar operates such that a clearance position of the shear bar is changeable with respect to the cutting too. The method includes assigning at least two interspaced sensors for detecting vibrations to the shear bar caused by the cutting tool upon contact with the shear bar, transmitting signals generated by the sensors to a common signal analysis device and, the common signal analysis device comparing the signals and determining a state of the cutting device.
