An agricultural wagon, for example a grain cart, of the type including an upright unload auger at the front end of the grain receiving bin which can be pivoted between left side and right side discharge positions, further includes a gearbox supported at the bottom end of the unload auger. The gearbox has a main shaft directly coupled to the unload auger. An input shaft of the gearbox, coupled to the main shaft by gear reducing bevel gears, receives an input rotation from a drive source external of the gearbox, for example the PTO of a tractor, for driving the main shaft and the unload auger. A second pair of bevel gears transfer some of the input rotation of the main shaft to an output shaft of the gearbox which is connected to a lower auger along the bottom of the grain receiving bin.

An agricultural wagon having a plurality of load sensors between a tow bar and a chassis. The load sensors are configured to sense the load of the wagon. The load sensors may sense the load of the wagon when it is supported on a tow coupling or on a stand. The agricultural wagon also has a collapsible cross conveyor, a lift-out tail gate and plastic hungry boards. The direction in which the cross conveyor feeds out material can be automatically selected based on the position or movement of the cross conveyor.
