a threshing drum;

at least one concave assembly positioned proximate to the threshing drum, the at least one concave assembly comprising a cylindrical frame and a plurality of modularized assemblies, each of the plurality of modularized assemblies being independently configurable and detachably connected to the frame of the at least one concave assembly, each of the plurality of modularized assemblies being removable from the cylindrical frame of the at least one concave assembly; and

a plurality of rods that are inserted within the at least one modularized assembly, each of the plurality of modularized assemblies comprising at least one of the plurality of rods extending substantially from one end of the each of the plurality of modularized assemblies to an opposite end of the each of the plurality of modularized assemblies, each of the plurality of modularized assemblies further comprising a structural member having a plurality of receiving members attached thereto, the at least one rod of the each of the plurality of modularized assemblies being supported by the plurality of receiving members of the structural member of the each of the plurality of modularized assemblies.

2. The threshing section of claim 1 , wherein each of the plurality of modularized assemblies is constructed such that it can remain connected to the at least one concave assembly while the each of the plurality of modularized assemblies is reconfigured.

3. The threshing section of claim 1 , wherein each of the rods extend substantially from one end of the each of the plurality of modularized assemblies to an opposite end of the each of the plurality of modularized assemblies.

4. The threshing section of claim 1 , wherein each of the plurality of receiving members of the structural member of each of the plurality of modularized assemblies comprises a plurality of openings, the at least one rod of the each of the plurality of modularized assemblies being positioned in one of the plurality of openings of the each of the plurality of receiving members of the structural member of the each of the plurality of modularized assemblies.

5. The threshing section of claim 4 , wherein the plurality of openings of each of the plurality of receiving members of the structural member of each of the plurality of modularized assemblies are substantially uniformly separated.

6. The threshing section of claim 4 , wherein the at least one rod of the each of the plurality of modularized assemblies has a circular cross section.

7. The threshing section claim 4 , wherein the plurality of openings of each of the plurality of receiving members of the structural member of each of the plurality of modularized assemblies are configured to receive rods of differing diameters.

8. The threshing section of claim 1 , further comprising at least one retaining plate removably coupled to the structural member of each of the plurality of modularized assemblies, the at least one retaining plate preventing a removal of the at least one rod of the each of the plurality of modularized assemblies from the structural member of the each of the plurality of modularized assemblies when the at least one retaining plate is coupled to the structural member of the each of the plurality of modularized assemblies.

9. The threshing section of claim 3 , wherein the plurality of rods of each of the plurality of modularized assemblies is up to five rods.

10. The threshing section of claim 3 , wherein the plurality of rods of each of the plurality of modularized assemblies are interchangeable.

11. The threshing section of claim 8 , wherein the at least one retaining plate removably coupled to the structural member of each of the plurality of modularized assemblies of the at least one concave assembly is connected to the frame.

12. The threshing section of claim 1 , wherein the at least one concave assembly and the threshing drum are adapted to be used in harvesting rice, and at least one of the at least one concave assembly and the threshing drum further comprises spikes extending therefrom.

13. A method of adjusting the threshing section according to claim 1 , the method comprising steps of:

removing at least one of the plurality of modularized assemblies from the frame of the at least one concave assembly;

modifying at least one of a position of a rod and a number of rods in the at least one of the plurality of modularized assemblies; and

replacing the at least one of the plurality of modularized assemblies in the frame of the at least one concave assembly.

14. The method of claim 13 , the method further comprising the steps of:

removing a retaining plate from an end of at least one of the plurality of modularized assemblies prior to the modifying step; and

replacing the retaining plate to the end of the at least one modularized assembly.

15. A threshing section of an agricultural harvester, the threshing section comprising:

a threshing drum;

at least one concave assembly positioned proximate to the threshing drum, the at least one concave assembly comprising a cylindrical frame and at least one modularized assembly, the at least one modularized assembly being independently configurable and detachably connected to the frame of the at least one concave assembly, the at least one modularized assembly being removable from the cylindrical frame of the at least one concave assembly; and

a plurality of rods that are inserted within the at least one modularized assembly, at least one of the plurality of rods extending substantially from one end of the at least one modularized assembly to an opposite end of the at least one modularized assembly, the at least one modularized assembly comprising a structural member having at least one receiving member attached thereto, the at least one rod being supported by the at least one receiving member.

16. The threshing section of claim 15 , wherein the at least one receiving member comprises a plurality of openings, the at least one rod being positioned in one of the plurality of openings.
