Moses drove a tractor

There has been a lot of rain over the past few days and even though the road drainage in Norway is pretty good there have been some floods. A farmer in a community not far from where I live has a novel way of helping motorists stranded by a flooded road. He drives through the water with the front loader lowered in front of his tractor causing a bow wave. The stranded car then simply drives behind the tractor in the trough created. I would like to see this in action. How close to the tractor must the car be? How fast does the tractor go? What if the car falls to far behind the tractor? Does it only work for short cars? Does it work at all or is this a joke?
