ABSTRACT:
An apparatus for attachment to the rear of a harvester-thresher to evenly distribute the by-product of threshing evenly over a wide area. The by-product is mainly straw and chaff. The apparatus is a single integrally combined unit formed of a straw spreader and a chaff spreader and driven by a single variable speed hydraulic motor. The by-product has a first portion engaged by the flexible and easily releasable flails of the straw spreader as it leaves the rear of the harvester-thresher, the remaining portion gravitates or is directed to the high volume air flow chaff spreader to complete the controllable distribution of the by-product. To increase the efficiency of the unit a shroud with deflectors has been placed around the chaff spreader.
