Abstract
Abstract A harvesting vehicle picks up the crop from the field, feeds it into a container, presses the crop into a compact stack and unloads the stack at a desired point of discharge. The press is reciprocated vertically with the container through use of a Ushaped lift swingable on the container and having arms that are operably coupled with the press. A normally locked endgate is controlled by the press such as to unlock the endgate and raise it to an open position for unloading in response to raising of the press. The container is tiltable for unloading purposes through use of an actuator common to the press such as to effect tilting after the endgate is opened and after the press is raised.
