Looking at possibly upgrading my 2000 8780xp to a 2005 9790 and am wondering how much more capacity ,ease of use reliability etc I would gain. My 8780xp has the updated front beater, the ATR rotor, mav chopper, engine set at 300 hp , fieldstar, about back auto stear. The 9790 has 1000 threshing hrs and my 8780xp has 1500 threshing hrs. Also what kind of money difference would be a good deal ?

The cab is better on the 9790. I prefer the Sisu engine over the Cummins. Have to go to Cummins dealer for repairs and they (local Cummins dealer) never acted interested in service. Also I think the final drives are heavier built on the 9790. As to trade difference a CaseIH salesman told me he looks on Fastline and Tractorhouse websites, throws out the high and low asking price, averages the rest and arrives at a value.

I would say about 15-20% more. We have a 9790 and my uncle has a 8780xp. And that's what I have figured for a difference. The 9790 cab is a big jump. And the 9790 is a lot easier for daily service. We have the QSL 9 cummins. I would look for a sisu. We have had quite a bit of grief with ours. Very temperamental engine.
