Wondering the difference in these different combine sizes from Case IH. Is it pretty much just horse power by turning more fuel to the engine or other differences to increase capacity. Same threshing and cleaning? Do they take basically the same parts? Been running an early model 2388 and looking at later models of these sizes and price differences. 77's may be a little cheaper.
