Hello, I am trying to readout the tractor speed with the ISO 11786 port (7 pin connector) in the roof of the tractor with a microcontroller. I will get results on the display but only if the tractor drive faster than 1km/h. For my purpose i need to read out the speed from 100 meter/hour and faster. Because we are harvesting cauliflower with this tractor. Does someone now of this is possible? Or do I have to find another way to meassure the tractor speed.
