Header trailers solve these problems rather easily, and do so for a very small amount of money. If you need to move two headers from one place to another, the Harvester would have to go back all the way (again, at a slow speed) to pick the other one up.

A Header Trailer solves this problem by mounting Headers sideways, aligning them with the axis of motion, effectively making them much narrower than they are when mounted on a Harvester.

Furthermore, Harvesters themselves tend to be slow vehicles, which take a long time to travel from place to place. Headers tend to be very wide, and transporting them from place to place while mounted on the front of a Harvester is somewhat tricky, as they can snag on trees and lamp-posts on the sides of roads, collide with buildings and cars, and otherwise be a bother. A Header Trailer is a type of trailer in Farming Simulator 17 designed specifically to carry Headers, and particularly the long Harvester Headers that cannot easily be transported on roads.
