A belt or auger conveyor is rotatably mounted on the frame of a seed cart or tender. The conveyor is mounted on a bracket, which in turn is mounted on the housing of a brake assembly. The brake assembly is rotatably mounted on a spindle fixed to a carriage, which is rollably mounted on tracks of the frame. The carriage allows the inlet of the roller to be longitudinally positioned for receiving seed or grain from a hopper or bulk container, while the spindle allows the outlet end of the conveyor to be rotated approximately 180° for positioning above a planter, truck or other receptacle. The brake assembly allows the rotational position of the conveyor to be infinitely adjusted without limitation to preset positions.
