A crop collection vehicle can be coupled to a prime mover for movement over the ground to collect and move crop to a desired site. A pick up and feeding mechanism at the front of the vehicle feeds crop to a chamber that is defined by a forward wall, a rear wall, side walls and a top. The chamber is enlarged with its walls bulged outwardly and a conveyor system within the chamber is positioned to receive and move crop received from the mechanism towards the rear of the chamber. The conveyor system includes a floor conveyor that slopes downwardly to the rear and articulated conveyors that coextend upwardly with a portion of the rear wall. The latter portion can be tilted together with the articulated conveyors to a downwardly extending position so that crop received from the floor conveyor can be formed and discharged as a coherent mass of crop intact. The rear wall and top of the chamber can be tilted by hydraulic piston assemblies and the mechanism together with conveyor system can be driven from the p. t. o. of the prime mover. A feeding device formed by cooperating opposing drums with tines that are moved to active crop loading positions is located at an entrance of the chamber so that crop is fed from between the drums through the chamber entrance. Alternatively, the feeding device can be reciprocating tine supports that progressively feed crop from a pick up to the floor conveyor. The conveyors of the system can be driven intermittently from a drive connection between the feeding device and the floor conveyor.
