A bale discharge chute normally is provided with a pair of spaced and parallel sides, a lower member and a movable upper pressure plate having links connecting the distal ends. The present invention includes a transverse anchor member for the upper connection of the links together with an adjustable compression spring reacting between the member and the pressure plate thus giving superior pressure plate control and preventing damage from occurring to the structure due to excessive tension yet at the time will permit upward movement of the pressure plate if a predetermined pressure is exceeded.
