So........I see your sieve is in upside down compared to mine ? At 3:39 Ive had my combine for over 6 years. Never had a problem yet. Mine has the smooth side up. Yours has the high ridges up. ??

I'm having the same problem

Learning the hard way about the 6600 combine..... For 35 years I picked all my corn with a two row New Idea 324 picker sheller. Used the small sheller. """" Alone """" I could pick enough corn to fill two semis per day. So...everyone told me I needed to buy a combine. I did. What a mistake !!!!! I used my 6600 combine .......... The most I can pick in one day """ alone """ is 1 and a half semi loads ! Point being ?? Your chasing wagons with a combine.....stopping to dump each time. With my two row picker.....I hook up a wagon......pick till its full..... get another wagon..........and keep moving ! Now the kicker.... fuel....... My Deutz 7085 tractor uses a half gallon per acre to pick corn. Try that with a 6600 combine ! ! Repairs ??? I spent 300 dollars on my New Idea over the 35 years I used it. The 6600 combine........oh the John Deere dealer loves you !!!!!!!!
