Even with a draper head, the combine has to carry the header during transport for both, short and long distances. I think it would make more sense to have the combine wheels, and preferrably tracks, up closer to the back side of the header, instead of having the header cantilevered so far forward. A long feederhouse with gradual slope is valuable for smooth feeding. Tracks help carry a lot larger headers. Perhaps front axles need to move forward to carry the larger headers.
