Recently talking to a Canadian farmer. He has GPS on his combine. Motor attached to steering wheel. More expensive setup is a servo that drives the steering hydraulics directly- no backlash. But what really interested me is that there are stationary earth-bound tower mounted correctors spread around the farmland which can bring the accuracy to an inch.
