The rotor is the way the crop is separated from the stalk. It spins against grates for a simple explanation and drops the seed in the bottom and spits the stalk out the back. The Case IH and JD ones use one large rotor and the New Holland uses two smaller ones which arguably is more efficient.

Here's a JD showing a bit more detail.

I'll add my .02 to this-I worked for I-H back when the Axial Flow Combine was developed (1440, 1460, 1480), and an I-H Engineer told me that the same guy designed both the Axial Flow and the Twin Rotor (TR)-the difference was he worked for each Company when he did it (traitor? ), and New Holland had to go TR because of the I-H patents-

Now that I am Deere, we are told (Deere propaganda?) that the Case I-H and TR's share the same platform, they just change the outside cladding and guts (I believe they are both produced in Grand Island NE and possibly one other plant?)-Deere, being the follower that they are sometimes, must have had to admit defeat and join the crowd with their design of the Axial Flow as it came much later (more than 10 Years after the I-H)-call me old, but while I like the hydraulic drive of the new machines, I think the simplicity of design was one of I-H's strengths (even though you had to service the Rotor Drive Belts)-
