Abstract: A centrifugal fan rotor having a frame with a rotary axis and a plurality of blades on the frame at circumferentially spaced locations around the rotary axis. The plurality of blades each has a leading edge and a trailing edge radially outside of the leading edge. The plurality of blades each has circumferentially oppositely facing first and second surfaces each extending between respective leading and trailing edges. The plurality of blades each has a material bonded at the leading edge and over only a portion of the exposed surface area of one of the first and second surfaces.

Abstract: An extension assembly for a processed crop storage tank on a combine. A closure assembly for a top opening on the tank has at least one panel with one surface area that is exposed to bound a part of an exterior space above the storage space with the closure assembly open. The extension assembly has a first extension panel with a first surface with a first area and a connecting system through which the first extension panel is operatively connected to the combine. The first extension panel is changeable between a deployed position and a stored position. In the deployed position the first surface and one surface define a combined exposed surface area that is greater than the first area of the first surface. The combined surface area is exposed to confine processed crop in the exterior space with the closure assembly open.

Abstract: A harvesting unit with a combine, having a user cab. A harvesting apparatus, advanced by the combine, has a frame and a harvesting assembly on the frame configured to process severed crop over a width between spaced sides of the frame. A fluid delivery system discharges pressurized fluid in discrete streams each directed to at least one of: a) facilitate severance of crop by the harvesting assembly; and b) facilitate advancement of severed crop rearwardly in relationship to the frame for further processing. A user can selectively vary at least one of: a) a volume of pressurized fluid; and b) a direction of pressurized fluid in the discrete streams. A control system has at least one actuator accessible and operable from outside of the cab through a user input to cause the at least one of the volume of pressurized fluid discharged, and direction of the pressurized fluid, in the discrete streams to be varied.

Abstract: A harvesting apparatus having a frame to be advanced over an area in which a crop is grown and a harvesting assembly on the frame configured to process severed crop. The harvesting assembly is configured to advance severed crop laterally to a delivery location between the laterally spaced sides of the frame and to and through a feed housing. A fluid delivery system discharges pressurized fluid to at least one of: a) facilitate severance of crop; and b) facilitate rearward advancement of severed crop. The fluid delivery system has at least a first pressurized fluid source through which pressurized fluid is delivered to laterally spaced outlets. A cleaning assembly has a first cleaning conduit assembly for directing pressurized fluid from the first pressurized fluid supply source in at least a first stream that repositions unusable crop and debris to reduce buildup thereof in the vicinity of the feed housing.

Abstract: A harvesting apparatus having a frame and a harvesting assembly on the frame configured to accommodate severed crop as the frame is advanced. A fluid delivery system causes pressurized fluid to be discharged in discrete streams each with a component that is directed to at least one of: a) facilitate severance of crop; and b) cause severed crop to be advanced rearwardly in relationship to the frame to a location for further processing. The fluid delivery system has: i) a primary conduit length extending laterally between the sides of the frame; ii) a plurality of laterally spaced outlets from which fluid from the primary conduit length is discharged; iii) a pressurized fluid source; and iv) a distributing conduit assembly that directs pressurized fluid from the pressurized fluid source to first and second locations from where pressurized fluid is directed in laterally opposite directions into the primary conduit length.
