Combines R85 9890 Sighting

If there nothing but a R75 with a bigger engine or 9790 with bigger engine, then shouldn't be much RandD required. Hopefully i'm wrong and there bigger combines with more seperator area and bigger rotor. Take care, Nathan

well nathan you have to admit there not following in JD footsteps yet. At least the difference between the sizes so far is more then just fuel delivery!!!!

Well good im glad there not fallowing JD. If you have nothing to do for a few minutes, go to JD website and pull up the page on the 9660 JD. Then on seperate pages have the 9760 and 9860 info. Then you flip back and forth between the 3 pages and nothing will change except the fuel capacity, grain tank and one or two more things that have nothing to do with speration. Just a screw turned on the pump. Take care, Nathan

Don't forget that the most important thing does change, though; the price! Deere's day will come; it just can't come soon enough. Sooner or later, some of those guys have to figure out that Deere is, shall we say, pulling the wool over their eyes. No matter how many are out there, it doesn't change the fact that the STS is simply the worst combine on the market among the major manufacturers. Nonetheless, some flock to it like flies on, well you get the picture. Go Gleaner!

The differences between the various Deere models are a little more than just horsepower, bin size and fuel tank capacity, especially between the 9860 and 9760. Various drive strengths and engine configurations can be brought into the "mix" as well, similar to the "differences" between an R65 and R75, where basic threshing and seperation capacities are also identical. CaseIH 2377 vs. 2388, New Holland CR940 vs. CR960, lexion 560R vs. 570R vs. 580R; - these machines all respectively possess similar seperation and cleaning capacities, just like Deere. This seems to be the trend among most manufacturers

9660 as well. The point is that JD takes a class VI and calls it a class VIII by adding hp. I haven't seen any drive differences that exist. Engines change (ie horsepower). The class VI STS processor is simply not a legitimate class VIII when you give it 375 hp, no matter how much JD says it is. The 580R lEXION may be the same chassis width, but the processing system is different. Sharing chassis across two modelsIJ Sure that's been done. But 3IJ Come on Deere.

You've actually got it backwards. The Deere STS STARTED OUT as the European 9880 and detuned to the 9660. There are substantial drive differences between the 9860 and 9760 (according to my dealer) but I agree with you when you note that there aren't sufficient differences between the 3 models. As far as Claas as concerned, well, the 3 models (560R, 570R and 580R) All "read" pretty similarly. What is the difference in the processing systemIJ We can't buy lexions in Ontario (yet)!
