An agricultural machine (20) is disclosed. The agricultural machine (20) comprising: a center section (25)； a wheel supporting the center section (25)； a wing section (24, 26) coupled to the center section (25)； and a hinge (50) positioned between the center section (25) and the wing section (24, 26) to permit the wing section (24, 26) to pivot about the center section (25), the hinge (50) comprising a first part (52) including a first protrusion defining a first aperture extending therethrough, the first part (52) coupled to or integrated in the center section (25), a second part (54) including a second protrusion, the second protrusion defining a second aperture extending therethrough, the second part (54) coupled to or integrated in the wing section (24, 26), a pin (82) having a first end and a second end, the pin (82) positioned to extend through the first and second apertures to couple the first part (52) and the second part (54) such that the wing section (24, 26) is pivotably coupled to the center section (25), a first fastener positioned adjacent the first end of the pin (82), the first fastener operable to couple the first part (52) to the center section (25) and to abut the first end of the pin (82) to thereby retain the pin (82) in the first and second apertures, and a second fastener positioned adjacent the second end of the pin (82), the second fastener operable to couple the first part (52) to the center section (25) and to abut the second end of the pin (82) to thereby retain the pin (82) in the first and second apertures.
