Abstract:
1. Spreader apparatus for a crop residue chopper of an agricultural harvesting machine, comprising: a spreader board including a surface having a plurality of vanes extending therealong defining a plurality of crop residue flow channels arranged in a row along the surface; and a pivot mount adapted to be mounted on a harvesting machine or a crop residue chopper for supporting the spreader board with the row of the crop residue flow channels extending at least generally horizontally across a discharge outlet of the crop residue chopper such that at least a substantial portion of a flow of crop residue propelled outwardly from the outlet will flow through the flow channels guided by the vanes so as to be deposited on a field on which the machine is located, the pivot mount supporting the spreader board and the vanes for unitary pivotal movement sidewardly about an upwardly and downwardly extending pivotal axis, to allow simultaneously altering an angular position of the spreader board and the vanes about the pivotal axis, wherein the pivot mount comprises an L shape pivot member having an upstanding end supported for rotation about the pivotal axis in a bushing mountable on a harvesting machine or a chopper, and a generally horizontal end received in a bushing mounted on the spreader board, to thereby allow unitary pivotability of the spreader board and the vanes about the pivotal axis and about a generally horizontal second axis.
