International ClassB60P 001/40AbstractA wagon for transporting grain and other particulate matter. The wagon is adapted to be attached to a tow vehicle. The wagon has a container which is provided with a forward wall. Within the container is a conduit. The conduit has a part which protrudes outwardly from the container and forwardly from the forward wall. Within the conduit is an auger. Pivotally attached to the part of the conduit which extends outwardly from the forward wall is a conduit extension member. The conduit extension member is pivotally movable to a position extending from the forward wall. Within the conduit extension member is an auger extension member. The auger extension member is operatively connected to the auger when the conduit extension member extends from the forward wall. Thus, a condition is established for discharging grain from the container of the wagon. The conduit extension member is pivotally movable to a position closely adjacent the forward wall. Thus, a condition is established for movement of the wagon upon a highway. The conduit extension member is thus always positioned for observation by the operator of the tow vehicle.Other References
