An agricultural harvesting head for an agricultural harvester comprising: a left frame section disposed to receive crop harvested on a left side of the agricultural harvesting head; a right frame section disposed to receive crop harvested on the right side of the agricultural harvesting head; a center frame section that is coupled to and disposed to receive the crop harvested from the left frame section and from the right frame section; and a gauge wheel assembly coupled to at least one section of the left frame section and the right frame section that is convertible from a harvesting position in which the first gauge wheel assembly supports the at least one section (138, 142) during crop harvesting, to a transport position in which the first gauge wheel assembly supports the at least one section (138, 142) for road transport; wherein the first gauge wheel assembly comprises a first elongate truss having a first end and a second end; a first wheel fixed to the first end of the first elongate truss; and a second wheel fixed to the second end of the first elongate truss and the head further comprises a first pivot joint coupled between a second elongate truss of the gauge wheel assembly and the at least one section (138, 142) that permits the elongate trusses (306, 307) and the first and second wheels (302, 304) to pivot as an assembly about a first pivot axis that extends parallel to a longitudinal extent of the at least one section (138, 142), and a second pivot joint coupled between the second elongate truss and the at least one section (138, 142) that permits the elongate trusses (306, 307) and the wheels (302, 304) to pivot as an assembly about a second pivot axis that extends vertically, characterized in that the first pivot joint includes two cylindrical members that are fixed to a plate, while two mating cylindrical members are fixed to an upper portion of the second elongate truss and pivot with respect to the two cylindrical members that are fixed to the plate such that the second elongate truss pivots with respect to the plate about the first pivot axis, and that the second pivot joint includes a vertical cylindrical member that is fixed to, extends upward from, and is normal to an upper surface of the plate, the vertical cylindrical member extending through a corresponding cylindrical aperture in a mating plate that is fixed to the bottom of the at least one section (138, 142). a left frame section disposed to receive crop harvested on a left side of the agricultural harvesting head; a right frame section disposed to receive crop harvested on the right side of the agricultural harvesting head; a center frame section that is coupled to and disposed to receive the crop harvested from the left frame section and from the right frame section; and a gauge wheel assembly coupled to at least one section of the left frame section and the right frame section that is convertible from a harvesting position in which the first gauge wheel assembly supports the at least one section (138, 142) during crop harvesting, to a transport position in which the first gauge wheel assembly supports the at least one section (138, 142) for road transport; wherein the first gauge wheel assembly comprises a first elongate truss having a first end and a second end; a first wheel fixed to the first end of the first elongate truss; and a second wheel fixed to the second end of the first elongate truss and the head further comprises a first pivot joint coupled between a second elongate truss of the gauge wheel assembly and the at least one section (138, 142) that permits the elongate trusses (306, 307) and the first and second wheels (302, 304) to pivot as an assembly about a first pivot axis that extends parallel to a longitudinal extent of the at least one section (138, 142), and a second pivot joint coupled between the second elongate truss and the at least one section (138, 142) that permits the elongate trusses (306, 307) and the wheels (302, 304) to pivot as an assembly about a second pivot axis that extends vertically, characterized in that the first pivot joint includes two cylindrical members that are fixed to a plate, while two mating cylindrical members are fixed to an upper portion of the second elongate truss and pivot with respect to the two cylindrical members that are fixed to the plate such that the second elongate truss pivots with respect to the plate about the first pivot axis, and that the second pivot joint includes a vertical cylindrical member that is fixed to, extends upward from, and is normal to an upper surface of the plate, the vertical cylindrical member extending through a corresponding cylindrical aperture in a mating plate that is fixed to the bottom of the at least one section (138, 142).
