I am thinking of upgrading from the old 750 Massey. I know I want a rotary and I think it should be a Case. Does anyone know the difference from a 1640 to a 1644? Why would I want one instead of the other?

Go with the 1644, it has the same rotor and sieve capacity as a 1666. The only real difference between the 1644 and 1666 are the final drives/transmission and the engine, 5.9 liter Cummins on the 1644 vs 8.3 liter on the 1666. If you are lucky some of the later 1644 even had the heavier final drives/transmission like the 1666.

We had a 1644 from 1996 till 2005 and it was an excellent machine. Handled a 6 row corn head very well and did pretty good with a 20' 1020 flex head. Ours had 30.5x32 rubber on it with small final drives. We took it easy with that setup and got along pretty well with it.

Her is a pic of ours the day we traded for the 2366.

If I remember right, the 44/66/88"s had most of the updates the 21XX series had, except for the cab and exterior design. I believe the main difference was in the rotor/thrashing system. Probably won"t see a lot of difference in a late 40 or 60 vs. 44 or 66, but will be a better machine in the long run if the money isn"t too much more. They seem to command a much higher price than a 40 or 60 model though.

Newer models even though they have higher hours aren't a bad thing, it's like a high mileage newer car. They have technology, and if you can get a good one, will fly through the field. It's amazing. Take a Blackberry phone and compare it to an Android phone. Pretty much the same.

Besides, unlike a conventional, it seems the Axial-Flows flows are much more rebuildable at high hours, and there are piles of update parts out there to make an older Axial do what a newer one will do.

The primary difference is HP the rest of the combine is virtually the same. They may have upgraded the final drives as well. Unless you have a particular machine in mind you probably would have an easier time finding a 1660 or 1666 as there are more of them out there. All are good machines in general, the separators are the same on all of the above except the 1666 has a little more sieve than the others. The 1660 and 1666 have heavier final drives and more HP. Any of them will make that 750 look like a toy. And they are much easier to work on as well. We went from a 750 to a 1460 then to a 1660 and have never looked back.
