Claim 10:
11. 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
at least one threshing insert positioned directly on the first surface and extending parallel with the first axis along a threshing section of the spine and at least one threshing insert positioned directly on the second surface and extending parallel with the second axis along the threshing section of the spine;
wherein, the threshing inserts are extensions from the corresponding first and second surface that assist the threshing process of the first and second rotor;
wherein, the spine 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.
