In the harvesting of agricultural crops, the crop is lifted off the ground continuously by a pickup unit as the vehicular harvesting machine is advanced across the field along the crop windrow. The machine has a crop-handling assembly which includes an elevator for receiving the crop from the pickup unit and continuously raising the crop to a level higher than the bed of the crop-receiving body of the machine. The crop-handling assembly also includes a conveyor which continuously receives the crop from the upper end of the elevator and moves the crop in a horizontal direction rearwardly for dumping into the open top of the body. The conveyor is extensible fore and aft of the body so that as the crop gravitates from the rear end of the conveyor it is spread evenly front to rear of the body. The entire elevatorconveyor assembly and the pickup unit thereon are also shiftable laterally with respect to the wheeled vehicle to spread the crop evenly from side to side of the body. The crop is fed between the side walls of the body and between upward extensions of such walls, and those extensions are shifted against the crop from time to time to compress it against the bed of the body and form a stack. Each extension also has a ram for compressing the sides of the stack in the body. The body is tiltable rearwardly and has a tailgate which may be unlocked and swung upwardly to permit the stack to be pushed rewardly out of the body off the tilted bed through use of a rearwardly moving, upright ''''false front.
