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.
