Abstract

A combine harvester comprises a concave, a cover plate or MOG limiter, and an over-center latch assembly that secures the cover plate or MOG limiter to an outer surface of the concave. The over-center latch assembly comprises a base plate including a pair of ears protruding therefrom, a handle in rotational communication with the pair of ears, a lever operatively connected to the base plate via a center pin in rotational communication with the handle that allows the lever to rotate with respect to the handle, and a loop at a distal end of the lever. A wire lock clevis pin is positioned between a center rail of the concave and a rail of the cover plate or MOG limiter. Each of the cover plate or MOG limiter includes hinge points positioned at an end opposite the over-center latch assembly for insertion into a cross bar of the concave.
