As a professor at a land grant college that studies crops, agricultural developments, livestock, and ag-economics, I have to disagree with you. Several colleges got together and ran independant tests on combines some years ago and found that properly set, a Deere combine is just as good as any on the market. We actually found that a 6620 compared very favorably with a 2166 in terms of grain loss and quality, and a 9500 matched it. The 2166 and 9500 were the best of the bunch, leaving around 2.1 bushels behind in corn, the Deere 6620 left 2.4, a New Holland TR 88 left 2.66, and a Gleaner R52 left 2.7. In other words, there wasn't enought difference to warrant a huge debate. All combines were set by their owners, and interestingly enough, the problems faced by the owners of combines other than Deeres were with reliability issues. Heck man, two years ago, at the Sunbelt Ag Expo in Moultrie, Georgia, a Case IH man told me and a friend that his company's combine was behind a Deere in terms of long term reliability. Now I'm not trying to start a color war, but saying all Deere's are junk is simply not true.
