Calling the Valtra RoboTrac a tractor is a bit deceptive. That's because it's also a robot, and it's much smaller than its industrious cousins. It's a fully programmable, automated farmhand that is designed to round out a farm team with whatever it's lacking. It can perform anything a farmer may need from tilling, plowing, disking, planting, harrowing, spraying, weeding, and other similar tasks. And, thanks to its small size, it can work the fields without wrecking them, all the while providing a loyal, preprogrammed source of labor.
