I'll measure the cabs for you next time I see both machines.  The Deere's are all spread around fields, so it might not be tomorrow.  There is no place to put a yield monitor in a 9600 that it's not going to hit your head if you go in the wrong way, the cab is just not wide enough. I've never seen one like you claim to have "in the pillar."  Ours are mounted to the mounting lugs that are welded into the cab post to mount them on, there's not really any place else to put it. 

I don't know why you think I have to copy all the specs of common combines for you when they are easily obtainable on the web and I already told you how they related.  You are basically saying that I am lying to you, or else that I do not know what I'm talking about.  I would think you would know better then to think either of those would be true.  

Per respective mfg's publications:

Threshing area on 9760 is 11.84 ft² vs 2205 in² on the 670

Separation area on 9760 is 2945 in² vs 2241 in² on the 670

Cleaning area on 9760 is 7053 in² vs 8296 in² on the 670

Hp on 9760 is 340 vs 350 on 670

window area in cabs: 9760 <52 ft² vs 62 ft² on 670.  Looking at both cabs shows that they basically have glass in all the same areas, so in absence of a cab area figure for the Deere, it's hard to imagine how it could be other then smaller given the much lower glass surface area.

In other words, one may be good and the other may be bad, but they are pretty much the same size machine.  

My original point was that there are much less expensive options then a quarter mill to get a combine like you said that Jon did not have.  I'm not really understanding why you find that to be such a contentious point when it basically agrees with your contention that it's hard to justify that kind of coin, but you have elected to argue with about every thing I said without having any substance to your argument.
