Abstract
A large round baler includes a chassis which forms a forward part of a baling chamber, with a rearward part of the chamber being formed by a bale discharge gate. The discharge gate is constructed of first and second, separate parts that are, either each separately pivotally connected to chassis or are mounted such that the second part is pivotally attached to the first part. The parts are arranged such that arms of the second part overlap the opposite sides of the first part. Different embodiments disclose various driving structures for causing one part to be moved by moving the other part, with the arrangement of the two parts resulting in the gate being quickly moved to its open position for discharging a bale.

In a large round baler including a chassis supported on wheels for being moved over the ground, said chassis defining a front section of a baling chamber, and a bale discharge gate defining a rear section of said baling chamber, said gate being vertically pivotally mounted on said chassis for movement between a lowered closed position and a raised open position, and a powered extensible and retractable arrangement being coupled between said chassis and gate for moving the latter between said closed and open positions, the improvement comprising:
- said discharge gate being defined by first and second said first part being vertically pivotally mounted to said chassis at a first location;
- said second part being vertically pivotally mounted to one of said front section of said baling chamber and first part of said discharge gate at a second location for vertical movement relative to said first part of said discharge gate;
- cooperating structure associated with said first and second parts of said discharge gate for effecting movement of one of said first and second parts of said discharge gate in response to movement of another of said first and second parts of said discharge gate;
- and said first and second locations being so spaced from each other that said second part undergoes a significantly greater angular displacement when going between said closed and open positions than does said first part.
