Abstract
A large round baler includes a combined tensioning and ejecting arrangement comprising a tensioning arm assembly mounted to an upper front region of the baler sidewalls. The tensioning arm assembly operates such that, after formation of a bale in the baling chamber and the discharge gate has been swung to its raised discharge position, the tensioning arm assembly pivots into a region occupied by the completed bale so as to positively eject the bale. The combined tensioning and ejecting arrangement includes front and rear arm assemblies which define a compact assembly and share a pair of double-acting tensioning actuators and a single-acting ejection actuator. The tensioning arm assembly may be used with a baler having a light weight bale discharge gate or with a baler having a discharge gate formed in part by rear sections of sidewalls forming opposite sides of the baling chamber. In an alternate embodiment, the ejection actuator is replaced with a coil extension spring.
