Abstract
A system and method for detecting a malfunction in a harvesting machine includes a sensor for mounting to the harvesting machine. The sensor is configured to measure a magnitude of a mechanical wave produced in the harvesting machine, and output a signal based on the magnitude. A controller receives the signal from the sensor. The controller is configured to process the signal and generate an alarm signal when a threshold is exceeded. An alarm unit is configured to receive the alarm signal from the controller when the threshold value is exceeded, and output an alarm to alert the operator of the malfunction. The malfunction can be a slipped clutch caused by a jammed condition, or other anomaly that generates a mechanical wave. The mechanical wave can be a sound wave or mechanical vibration traveling through one or more parts of the harvesting machine.
