8. An agricultural vehicle, comprising:
a chassis;
at least one connecting member; and
a header, comprising:
a frame removably attached to the at least one connecting member; and
a transport assembly connected to the frame and configured for being positioned in a transport position and a storage position, the transport assembly comprising:
a tandem axle support device comprising at least one pivot shaft pivotally connected to the frame, a first walking beam, and a second walking beam, the first and second walking beams are operably connected to and moveable by the at least one pivot shaft; and
at least four wheels comprising a first pair of tandem wheels removably connected to the first walking beam and a second pair of tandem wheels removably connected to the second walking beam,
wherein the at least one pivot shaft defines a longitudinal axis, the first walking beam defines a first longitudinal axis, and the second walking beam defines a second longitudinal axis, and
wherein when the at least one pivot shaft is folded relative to the frame, the first and second longitudinal axes of the first walking beam and the second walking beam are coplanar with the longitudinal axis of the at least one pivot shaft in the storage position.
9. The agricultural vehicle of claim 8 , wherein the frame of the header further comprises at least one lift pocket which receives the at least one connecting member, and the at least one lift pocket is positioned in between the first pair of tandem wheels.
10. The agricultural vehicle of claim 8 , wherein the at least one pivot shaft is folded underneath the header and parallel to a field in the storage position.
11. The agricultural vehicle of claim 8 , wherein the tandem axle support device further comprises a transverse shaft connected to the at least one pivot shaft, and the transverse shaft comprises a first end pivotally connected to the first walking beam and a second end pivotally connected to the second walking beam.
12. The agricultural vehicle of claim 11 , wherein the transverse shaft is in the form of a telescoping transverse shaft such that the telescoping transverse shaft is extended in the transport position and the telescoping transverse shaft is retracted in the storage position.
13. The agricultural vehicle of claim 11 , wherein the tandem axle support device further comprises at least one truss member removably interconnected between the frame and the transverse shaft.
14. The agricultural vehicle of claim 13 , wherein the at least one truss member comprises a pair of truss members.
15. The agricultural vehicle of claim 8 , wherein the at least four wheels are respectively connected to the first and second walking beams in the transport position, and the at least four wheels are disconnected from the first and second walking beams in the storage position.
16. A method for transporting a header comprising a frame and a transport assembly connected to the frame and configured for being positioned in a transport position and a storage position, the transport assembly comprising a tandem axle support device comprising at least one pivot shaft pivotally connected to the frame, a first walking beam, and a second walking beam, the first and second walking beams are operably connected to and moveable by the at least one pivot shaft, and at least four wheels comprising a first pair of tandem wheels removably connected to the first walking beam and a second pair of tandem wheels removably connected to the second walking beam, the method comprising:
