Patent ID: 8025312

Claim:
An agricultural header assembly to be carried across a field by an implement in a normal operational direction and being removable from the implement for transport, said header assembly comprising: a header operable to cut and convey crop as the header assembly is moved across the field, said header including— a header frame including a rigid beam extending laterally relative to the normal operational direction; a crop-cutting assembly mounted to the header frame and extending laterally along the frame; a crop-conveying assembly supported on the header frame rearwardly of the crop-cutting assembly and configured to convey crop severed by the crop-cutting assembly, said header being in a transport orientation when the rigid beam is out of vertical alignment with the header center of gravity; and a transport assembly operable to support the header in the transport orientation when the header assembly is removed from the implement, said transport assembly including— a first pair of spaced apart wheels shiftably connected to the rigid beam for movement between a transport position and a field position, said first pair of wheels defining a first midpoint therebetween when in the transport position, said first midpoint being disposed in general vertical alignment with the header center of gravity when the header is in the transport orientation to substantially balance the header on the transport assembly, with one of the first wheels being closer to the rigid beam than the other of the first wheels.
