Industrial design chair David Ringholz (center) and Ph.D. student John Pritchard discuss tractor rollovers with Iowa secretary of agriculture Bill Northey during the Iowa State Day at the Capitol on Feb. 26. Ringholz's research team has developed the prototype of a tractor-mounted device that addresses one aspect of tractor rollover fatalities: response time.
