How costly is Row Rage? Running over the row for even one second at 15 mph will take out more than 90 corn plans. Imagine how that can add up over a day. To overcome the Row Rage that happens with manual steering, John Deere introduces all-new AutoTrac™ sprayer guidance systems. New AutoTrac™ Vision uses a front-mounted camera to see early-season corn, soybeans and cotton at least 6 inches (15 cm) high. An industry exclusive from John Deere.
