Abstract
An agricultural harvester with crop residue spreaders distributing crop residue laterally. Each crop residue spreader has a plurality of radially extending bats rotatable within a housing for directing residue from an axially directed inlet radially outward through an outer outlet. The housing has an outer wall with a height that increases axially in a uniform fashion around the periphery to minimize if not eliminate recirculation of residue to the inlet.
Claims9
A crop reside spreader comprising:
- a plurality of radially extending bats mounted for rotational movement about an axis A for moving residue;
- and
- a housing surrounding the bats and having an inlet for residue adjacent the axis A and a radially outward outlet,
- wherein the housing has a width measured in a direction parallel to the axis A that increases from a minimum width adjacent the outlet around its periphery up to the outlet.
