<p>PROBLEM TO BE SOLVED: To provide a self-diagnostic mechanism of a combine harvester capable of rapidly confirming a wrong spot with saving time and improved in workability by installing a self-diagnostic display unit which indicates abnormalities of each of controllers themselves by carrying out the self-diagnosis. SOLUTION: In this self-diagnostic mechanism of a combine harvester, controllers A, B and C which control and operate each functional part such as a discharge device, a leaping, an electron governor, etc., are mounted, a self-diagnostic displaying unit P which displays abnormalities of the controllers A, B and C themselves and the display unit displays the name of an abnormal controller and the result of a diagnosis by displaying in letters and numbers. It is preferable to constitute to display a self-diagnosis confirmation, which confirms a normally operating state of the self-diagnostic device, and a self- diagnostic output irrespective of a self-diagnostic result for a certain time after putting on the power of the self-diagnostic device.</p> |
