A grain cart comprising: a wheeled frame; a container mounted on said frame and configured to hold a quantity of grain, said container having front, rear and laterally opposed side walls (120, 122, 124, 126); a folding auger assembly having upper and lower auger assembly portions (102, 106) connected by a joint assembly, said lower auger assembly portion having a lower auger housing with first and second ends and a lower auger portion rotatably disposed in said lower auger housing, and said upper auger assembly portion having an upper auger housing with first and second ends and an upper auger portion rotatably disposed in said upper auger housing; wherein said first end of said lower auger housing has an intake opening proximate a bottom of said container to receive grain and said second end of said lower auger housing is disposed adjacent a forward corner of said container where said front wall intersects one of said laterally opposed side walls (122, 124); wherein said first end of said upper auger housing is disposed adjacent said second end of said lower auger housing and said second end of said upper auger housing has a discharge opening to discharge grain from said container; and wherein said joint assembly defines a pivot axis about which said upper auger assembly portion is pivotable relative to said lower auger assembly portion between an operating position in which said first end of said upper auger assembly portion abuts said second end of said lower auger assembly portion to permit grain to be discharged from said container and a transport position in which said upper auger assembly portion extends downwardly from said second end of said lower auger assembly portion diagonally across said front wall of said container substantially between said laterally opposed side walls (122, 124) of said container to facilitate transporting said grain cart; characterized in that said joint assembly is configured to allow said pivot axis to move as said upper auger assembly portion is pivoted between said operating and transport positions. a wheeled frame; a container mounted on said frame and configured to hold a quantity of grain, said container having front, rear and laterally opposed side walls (120, 122, 124, 126); a folding auger assembly having upper and lower auger assembly portions (102, 106) connected by a joint assembly, said lower auger assembly portion having a lower auger housing with first and second ends and a lower auger portion rotatably disposed in said lower auger housing, and said upper auger assembly portion having an upper auger housing with first and second ends and an upper auger portion rotatably disposed in said upper auger housing; wherein said first end of said lower auger housing has an intake opening proximate a bottom of said container to receive grain and said second end of said lower auger housing is disposed adjacent a forward corner of said container where said front wall intersects one of said laterally opposed side walls (122, 124); wherein said first end of said upper auger housing is disposed adjacent said second end of said lower auger housing and said second end of said upper auger housing has a discharge opening to discharge grain from said container; and wherein said joint assembly defines a pivot axis about which said upper auger assembly portion is pivotable relative to said lower auger assembly portion between an operating position in which said first end of said upper auger assembly portion abuts said second end of said lower auger assembly portion to permit grain to be discharged from said container and a transport position in which said upper auger assembly portion extends downwardly from said second end of said lower auger assembly portion diagonally across said front wall of said container substantially between said laterally opposed side walls (122, 124) of said container to facilitate transporting said grain cart; characterized in that said joint assembly is configured to allow said pivot axis to move as said upper auger assembly portion is pivoted between said operating and transport positions.
