Automated Grain Cart Tractor using GPS

Sceenshot from video

A video of a tractor pulling the grain card to unload a combine that has no driver. I read in one of their brochures that John Deere sells equipment that a farmer can mount on the side of the field that will correct a tractor's GPS to two-inch accuracy. The yellow device on top of the cab is the GPS receiver.

Automation is finally coming out of the factory and going into the field.
