A system for transferring material from a storage container to a farm implement includes a transfer conveyor transportable on a farm implement including a trailer, a bin mounted on the trailer, a cart conveyor, and a dock mounted on the trailer forwardly or rearwardly of the bin to stow the transfer conveyor. The transfer conveyor includes a wheeled receptacle defining a receiving area with an open top and first and second conveyor portions. The first conveyor portion is disposed within the receiving area and the second conveyor portion pivotable between a storage position in which the second conveyor portion is positioned across the top of the receptacle and an operating position in which the second conveyor portion extends outwardly from the receptacle. The dock is mounted to pivot from a horizontal stowed position disposed across the trailer to a tilted deployed position extending from the trailer to the ground to allow the transfer conveyor to be loaded onto and unloaded from the trailer.
