I have hauled these machines and other similar sized combines around to research plots on a 24' tandem dual gooseneck - 8.5' wide. I had the trailer special-made to achieve a lower deck height (31") by piercing the frame for the cross members, and running low profile tires. It's up there, but we have not had any problems getting around. Be sure to pull it with some HP though, as that wind resistance on the windshield is like a brick wall.
