ABSTRACT:
A torque arm assembly for securing a silo unloader output chute. The assembly preferably comprises first frame means adapted to extend vertically upwardly from the silo unloader and second, generally horizontal tracking frame means pivotally coupled to the first frame section for sequentially engaging silage discharge orifices. In operation the tracking frame alternately engages and then withdraws from each silo silage discharge orifice before dropping to a lower position. The tracking frame preferably includes latching means for selectively grasping the silo's discharge orifice partitions to control downward movement and cooperating roller wheel means for smoothly contacting the discharge orifice partitions to facilitate proper subsequent engagement within a lower discharge orifice. The latching means preferably comprises a fork portion pivotally coupled to the tracking means which temporarily grasps the orifice partitions to delay downward movement. A suspension bracket included to secure the silage discharge output chute preferably includes bearing wheels which ride on the tracking section, preventing interference with the movement of same.
