4. The agricultural vehicle according to claim 1 , wherein said at least one additional section includes:

at least one support stabilizer;

a pair of transport wheels configured to support the at least one additional section in transportation; and

a tongue configured to connect the at least one additional section to the agricultural vehicle or the other vehicle in transportation.

5. The agricultural vehicle according to claim 1 , wherein the sectional header system includes at least two additional sections, each said additional section is respectively coupled to one of said lateral ends of the center section in harvesting, and said at least two additional sections are decoupled from the center section in transportation such that only the center section remains attached to the agricultural vehicle.

6. The agricultural vehicle according to claim 5 , wherein in transportation said at least two additional sections are coupled to each other such that they are moveable as a single unit.

7. The agricultural vehicle according to claim 1 , wherein said at least one additional section can pivot with respect to the center section in harvesting.

8. The agricultural vehicle according to claim 1 , wherein said at least one actuator is configured for moving the at least one additional section to be in a lifted state, said at least one connector pivotally connecting said center section and said at least one additional section such that actuation of the at least one actuator causes the at least one additional section to pivot about the at least one connector.

9. The agricultural vehicle according to claim 1 , wherein said at least one actuator is in the form of at least one flotation cylinder and said at least one connector is in the form of at least one clamp.

10. A sectional header system, comprising:

a center section having a pair of lateral ends;

at least one additional section; and

at least one coupling assembly including at least one actuator and at least one connector, said at least one coupling assembly removably connecting the center section to the at least one additional section, wherein the at least one additional section is coupled to the center section in harvesting of a crop material and the at least one additional section is decoupled from the center section in transportation of the sectional header system such that the at least one additional section is entirely disconnectable from the center section and the agricultural vehicle and subsequently towable by the agricultural vehicle or another vehicle in transportation of the sectional header system.

11. The sectional header system according to claim 10 , wherein said center section is attachable to the agricultural vehicle and said center section remains attached to the agricultural vehicle in transportation of the sectional header system.

12. The sectional header system according to claim 11 , wherein said center section has a width that is approximately the same as a width of the agricultural vehicle.

13. The sectional header system according to claim 10 , wherein the at least one additional section includes:

at least one support stabilizer;

a pair of transport wheels configured to support the at least one additional section in transportation; and

a tongue configured to connect the at least one additional section to the agricultural vehicle or the other vehicle in transportation.

14. The sectional header system according to claim 10 , wherein the sectional header system includes at least two additional sections, each said additional section is respectively coupled to one of said lateral ends of the center section in harvesting, and said at least two additional sections are decoupled from the center section in transportation such that only the center section remains attached to the agricultural vehicle.

15. The sectional header system according to claim 14 , wherein in transportation said at least two additional sections are coupled to each other such that they are moveable as a single unit.

16. The sectional header system according to claim 10 , wherein said at least one additional section can pivot with respect to the center section in harvesting.

17. The sectional header system according to claim 10 , wherein said at least one actuator is configured for moving the at least one additional section to be in a lifted state, said at least one connector pivotally connecting said center section and said at least one additional section such that actuation of the at least one actuator causes the at least one additional section to pivot about the at least one connector.

18. The sectional header system according to claim 10 , wherein said at least one actuator is in the form of at least one flotation cylinder and said at least one connector is in the form of at least one clamp.

19. A method, comprising the steps of:

providing a sectional header system for an agricultural vehicle, said sectional header system including:

a center section having a pair of lateral ends;

at least one additional section; and

at least one coupling assembly including at least one actuator and at least one connector, said at least one coupling assembly removably connecting the center section to the at least one additional section, wherein the at least one additional section is coupled to the center section in a harvesting mode and the at least one additional section is decoupled from the center section in a transportation mode for transporting the sectional header system such that the at least one additional section is entirely disconnectable from the center section and the agricultural vehicle and subsequently towable by the agricultural vehicle or another vehicle for transporting the sectional header system;

converting the sectional header system from the harvesting mode into the transportation mode by disconnecting said at least one additional section from said center section such that only the center section remains attached to the agricultural vehicle; and

converting the sectional header system from the transportation mode into the harvesting mode by connecting said at least one additional section to said center section.

20. The method according to claim 19 , wherein the sectional header system includes at least two additional sections, each said additional section is respectively coupled to one of said lateral ends of the center section in the harvesting mode, and said at least two additional sections are decoupled from the center section in the transportation mode.
