You may think that self-driving vehicles are relatively new. But self-driving tractors have been in farm fields for two decades.
Two hands-free guidance systems help these John Deere tractors stay on course: sensor paddles on the wheels detect stalks and AutoTrac Vision uses a front-mounted camera to see early-season crops drive down the rows without damaging the crop.
For safety, a worker has to be inside the cab monitoring the operations. With integrated tablets and apps, farmers can monitor planting and harvesting, yield, and risk.
