demonstrated an autonomous tractor and grain cart alongside a combine at Son D Farms near Adrian, Minnesota, on 21 October. The Globe reported from the event, one stop on the company's harvest tour.
The tractor uses a autonomy kit and pulls an grain cart between the field edge and combine. The combine operator controls and monitors the system. Lidar, radar and cameras detect obstacles and stop the tractor, according to 's representative.
This was a working-field demonstration of commercially available technology, not evidence that the farm ran an entire harvest without drivers. The report does not give task-completion rates, intervention counts or measured labour savings.
