Well, I know a Gleaner can do a clean job. I also know a Case can do a good clean job. Know what elseIJ....A Deere does a good clean job. I've put no less than 15,000hrs running all sorts of combines and I'm only 32 years old. I know that doesn't qualify me as a great expert, but it does qualify me to speak some. The mach. is only as good as the person who sets it and runs it. Year after year, I've seen Deeres..both 20 series and 9000 series put wheat in the bin that was below 2_10ths of one persent trash_dockage. This year we ran 4.9-5.0 mph with a 30' in 60-70bu_ac. wheat. If there was even 1 percent out the back, I nor the farmer couldn't find it. I've seen Cases and Gleaners also do the same type of quality. I've also seen them do such a lousy job, It turned my stomach. For years, I've heard the same story everywhere I go.....This farmer will never allow a Deere back in his field. Down the road 5 miles, another says the same about a Case. Then about a Gleaner...so on and so on....I have a book 3 inches thick full of names of farmers from Texas to Canada, Montana, No. Dakota and Idaho. I've heard it all in 20 years of chasing the wheat harvest. CM
