LAS VEGAS: It has GPS, lasers, computer vision, and uses machine learning and sensors to be more efficient. This is the new high-tech farm equipment from John Deere, which made its first Consumer Electronics Show appearance this week to highlight the importance of tech in farming. 

Deere brought its massive agricultural combine and GPS-guided tractor to the Las Vegas technology event, making the point that farming is more than sticking a finger up to gauge the weather.
