Abstract
A discharge chute for a material reducing machine having a discharge opening includes a plurality of adjacent chute segments and a linkage system. The plurality of adjacent chute segments includes a rear chute segment, an intermediate chute segment and a front chute segment, each of which is pivotally connected to an adjacent chute segment. The linkage system includes a plurality of links that interconnect the adjacent chute segments, and an actuator that is adapted to cause the discharge chute to be steered to the left by pivoting the intermediate chute segment to the left with respect to the adjacent rear chute segment, and to cause the discharge chute to be steered to the right by pivoting the intermediate chute segment to the right with respect to the adjacent rear chute segment.
