The following information is a Web Extra from the pages of Farm Journal. It corresponds with the article "Follow the Combine." You can find the article in Farm Journal's November 2012 issue. 

In the middle of harvest, Monmouth, Ill., farmer Rick Elliott got a call from one of the neighbors.
"He was driving by and asked me ‘Is there anyone in that grain cart tractor?!" Rick says.

But there was no cause for alarm. Elliott’s tractor was following the combine through the field, unloading on the go, without anyone sitting in the cab. His farm was one of three in western Illinois testing the Kinze Autonomous Harvest System.
