As you suggested, the TC35/40/45 were all Class III and the TC48/55 was Class IV. I may have made some mistakes with my groupings and that shows how little it means. As long as you know the Class IIIs are a bigger frame size than Class IIs, that's all you really need to know. I believe the new TC35 may be a progression of the TC34 and is now a smaller frame size like the TC29/33/34. The new numbers and changes have me so confused that I'm afraid to comment on most issues.

EDIT: I just went to NH's new site. In the Boomer tractors, the numbers are :

1xxx
2xxx
3xxx
4xxx

Those numbers correspond to the previous "class" designations. My calling them by the class is probably no longer valid. I should use the new designations when talking about new tractors. Technically, my tractor is a Class III because that's what they called them when I bought mine. However, if you can't find that in reference material, it isn't much use.

The large frame compacts are considered a Class IV. The NH numbering system doesn't correspond to frame class, just to add more confusion on the subject!
Class IV Compact Tractors

The 4000 series are considered utility tractors not compacts.
