Self-driving electric tractor promises eco-friendly, hands-off farming

The autonomous tractor world is heating up, apparently. CNH Industrial has unveiled what it says is the "first" electric light tractor prototype with self-driving features, the New Holland T4 Electric Power. The machine promises zero emissions, quieter operation than diesel models and (according to CNH) lower running costs while reducing the amount of time farmers spend behind the wheel. Sensors and cameras on the roof help the vehicle complete tasks, dodge obstacles and work in harmony with other equipment. You can even activate it from your phone.
