We're using an agleader Integra monitor for our yield monitor in a Gleaner S67 combine. The head height % setting that needs to be entered to start/stop the logging of yield, when raising/ lowering the head, the % doesn't change. So the % stays at zero. The logging continues until the machine threshing is turned off or I'm over what has already mapped. The height numbers change on the Agco monitor so I'm pretty sure that the sensor is working. Any idea what could be the solution.
