Abstract: A grain harvesting vehicle is configured to harvest a grain. A chaffer is configured to separate grain from material other than grain (MOG). A grate is positioned rearward of the chaffer. The grate includes a grate panel having an upper surface and a lower surface and an aperture in the grate panel extending between the upper surface and the lower surface. The aperture has a first end nearer the chaffer and a second end opposite the first end. The grate further includes a ramp portion extending above the grate panel from adjacent the first end of the aperture toward the second end of the aperture. A grain sensor has a sensing location positioned at a height below the grate.

Abstract: Harvesting machines and agricultural harvesting heads for harvesting machines are disclosed herein. A harvesting machine includes a frame, an elongate reciprocating knife, a conveyor system, a drum conveyor, and a crop deflector. The elongate reciprocating knife is coupled to a forward edge of the frame and configured to cut crop material adjacent to the ground. The conveyor system is supported by the frame and configured to carry cut crop material toward a central portion of the frame and rearward therefrom. The drum conveyor is located directly behind at least a portion of the conveyor system, and the drum conveyor includes an elongate cylindrical drum supported for rotation on the frame about a drum axis and a plurality of elongate fingers that at least partially extend through an outer wall of the cylindrical drum.
