1. A spine for providing structural support for a dual rotor harvesting machine, comprising:
a first surface of the spine that is solid and directed towards a first rotor configured to rotate about a first axis;
a second surface of the spine that is solid and directed towards a second rotor configured to rotate about a second axis; and
a plurality of threshing inserts positioned directly on the first surface and extending longitudinally along the first axis and a plurality of threshing inserts positioned directly on the second surface and extending longitudinally along the second axis;
wherein the spine extends between the first axis and second axis and is coupled to a first cover element and a first concave positioned partially around the first rotor to partially define a first cavity for the first rotor and the spine is coupled to a second cover element and a second concave to partially define a second cavity for the second rotor;
wherein the threshing inserts are removeably coupled to the spine to selectively expose the corresponding solid surface of the first surface or the second surface of the spine;
wherein the threshing inserts are removable directly from the first surface of the spine or the second surface of the spine; and wherein the plurality of threshing inserts positioned on the first surface extends along the spine from the first cover element to the first concave, and the plurality of threshing inserts positioned on the second surface extends along the spine from the second cover element to the second concave.
