1. An over-center latch for attaching a cover plate or MOG limiter to an outer surface of a concave for a combine comprising:
a subbase including a pair of ears protruding therefrom;
a handle in rotational communication with the pair of ears at a base of the handle;
a center pin positioned between the base of the handle and a distal end of the handle configured to be in rotational communication with the handle;
a lever attached at a base of the lever to the center pin, wherein the center pin allows the lever to rotate with respect to a handle;
a loop at a distal end of the lever opposite the base of the lever; and
a base plate attached to a bottom of the subbase;
wherein the cover plate or MOG limiter includes:
rails running curvilinear along a length of the cover plate or MOG limiter;
extended mounting portions extending outwardly from an outer surface of each of the rails and each of the extended mounting portions forming an edge, wherein each of the edges are flat and angled away from the rails such that no portion of the edges are parallel to any portion of the outer surface of the rails from which the extended mounting portions extend;
wherein the base plate attaches to the edges of the extended mounting portions;
wherein either the handle or the lever can be pulled into a vertical position orthogonal the subbase.
