ABSTRACT:
Rotary accelerating apparatus for a vertical crop residue spreader of an agricultural combine capable of receiving, combining and accelerating a relatively high velocity of voluminous flow of relatively heavy, bulky crop residue including straw and the like deflected downwardly from the thresher of the combine, and a weaker, less voluminous flow of chaff and air from the cleaning system of the combine located forwardly of the spreader, by generating a negative pressure or suction condition in the vicinity of the chaff flow for overcoming any undesirable back pressure condition that interferes with induction of the crop residue flow from the cleaning system and which facilitates air flow through the chassis region of the combine to reduce conditions leading to undesirable dust buildup and other problems.
