Abstract: An agricultural machine includes: a base member; a leading edge coupled with the base member and configured for receiving a flow of a material; and an assembly coupled with the base member, the assembly including a device and at least one flexible wiper coupled with the device, the device being configured for rotating and thereby for rotating the at least one flexible wiper therewith, said at least one flexible wiper thereby being configured for cleaning the material from the leading edge.

Abstract: An agricultural harvester with a crop processing apparatus. The crop processing apparatus is configured for separating crop material from crop residue and for discharging crop residue therefrom. The agricultural harvester includes a duct for directing a stream of crop residue downstream in the agricultural combine in a generally downward direction, a pair of laterally spaced spreader devices positioned downstream of and below the crop residue duct for distributing crop residue laterally, and deflectors spaced outwardly of the spreader devices and oriented generally in a vertical plane. The deflectors are mounted at a first upstream edge relative to the flow of the crop residue stream and extend downstream. The deflectors have an upper edge curved toward the spreader devices to an increasing extent away from the upstream edge.
