Abstract text

A residue splitter apparatus for use with a horizontal spreader assembly that employs a pair of spreader paddles disposed side-by-side to rotate about respective generally vertical axes for controlling the spread width distribution of crop residue on and over a field, and the method of use thereof, including a flow guide element located generally intermediate to the spreader paddles of the horizontal spreader assembly with crop residue flow surfaces that extend rearwardly from a front edge portion of the flow guide element and sidewardly to free end portions generally aft of at least portions of the spreader paddles to receive and direct the flow of crop residue from such spreader paddles. Preferably, the flow guide element is laterally expandable to permit the flow of crop residue from the spreader paddles to be adjustably varied to effect a desired pattern of crop residue flow from the spreader paddles, for instance, so as to better and more evenly distribute the flow side-to-side over a swath of an agricultural field from which the crop was harvested.
