Workshops in the Autonomous Tractor Co. research facility
The workshops in the Autonomous Tractor Co. research facility at St. Michael, Minn., are busy with a variety of projects. Some are welding parts for the grain transport, which has to be done by late July for a fair. Others are working on electronics. Some are volunteers, retired from related professions in their 70s, working for expenses. Photo taken June 24, 2013. (Agweek/Mikkel Pates)
