Combine harvesters may include crop processing systems having a grate subassemblies with flaps that, in some instances, are divided into groups that are independently movable and moveable in opposite directions between a fully open position and a fully closed position. Further, each of the grate assemblies may include an actuator that is operable to actuate simultaneously a portion of the flaps on each of the grate assemblies.

An access door for a combine harvester includes a body having a top, a bottom, a first side, and a second side. The body includes a height defined between the top and the bottom and a width defined between the first side and the second side. A plurality of ribs is integrally formed in the body for adding rigidity thereto, and a deflector is integrally formed with the body and protrudes therefrom. The deflector has a top surface and a width that is substantially the same as the width of the body. The body is defined within a first plane and the top surface is defined within a second plane such that the second plane is disposed at an angle less than 90° from the first plane.

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.
