North American firm Smart Ag is believed to be the first to market a system that allows a combine driver
to control a driverless chaser bin tractor

North American arable farmers are finding it increasingly difficult to recruit seasonal tractor drivers for a few hundred hours of harvest chaser bin work. But help is now at hand in the form of plug-and-play driverless technology called AutoCart, which is believed to be the first time a farmer can take a tractor, make it driverless, and then with the flick of a switch drive it like a normal tractor.
