The invention provides a trailer box for receiving and discharging a load of freshly harvested tobacco leaves having an average minimum tobacco leaf dimension. The trailer box includes a frame carrying a deck having an upper surface. The trailer box also includes an endless conveyor adapted to travel over the upper surface on a rearward journey. The conveyor include s a conveying loop extending between axles mounted to the frame. The conveyor also includes support bars having upper support bar surfaces attached transversely to the conveying loop and spaced from each other a distance selected to be less than the average minimum tobacco leaf dimensi on to suspend the load. The conveying loop maintains a separation between the upper support bar surfaces and the upper surface of the deck during the rearward journey of the conveyor, selected to minimize friction between the suspended load and the upper surface of the deck.
