Abstract
A large round baler is equipped with a combined belt-tensioning and bale ejecting arrangement including front and rear tensioning arm assemblies mounted at an upper front location adjacent a baling chamber. Extensible and retractable belt-tensioning actuators are coupled between the arm assemblies and serve to yieldably restrain movement of the arms, which support and or guide runs of bale-forming belts, in response to the growth of a bale being formed in the baling chamber. One end of each of the tensioning actuators is coupled to the rear arm assembly in such a way that the actuator may be cycled to move over center relative to the pivot axis of the rear arm assembly once the bale is completely formed so that the actuators may be used to aid in ejecting the bale once the discharge gate is opened.
