kp, we had similar problems with the draper heads on Ml lease combine. I suspect a weak center draper motor, or case drain line restriction causing high back pressure. High ambient temperature associate with summer time heat can create a lot of seal problems with all the hydraulic motors on the drapers. Frankly, its tough to hydraulic drive two side drapers, center feed draper and center drum without creating excessive heat. Just too much hydraulic complexity compared to the auger header alternative. I have been working on development of new centerline header drive targeted for a savey major manufacturer. It supports and drives the two split augers in the middle. This controls center auger to stripper clearance consistently and provides for dual slip clutches (50% torque to left and right side augers). Further more, the dual center line knife drive has opposed sickles which are just half the length of end driven sickles. ClAD also eliminates the knife drive case weight from the ends of the header and requires support strength for just 25% of auger weight on each end. So far, the NIH majors have not publicly acknowledged the benefits of the centerline drive concept. But they are not dumb, just stubborn and protective of their current products. Eventually, the safety improvements and material cost savings will cause them all to want on the band wagon and they will claim this to be the best thing since STS. This could be sooner or later, depending on how quickly farmers can be made aware of the potential improves and cost saving of CHIS and ClAD designs. Once farmers begin requesting and demanding the related CHIS, Combine Header Interface Standardization. If any of you agree, please let them and us know if you support or reject this CHIS project. It would be great to have you give a related presentation at your next farmer _ harvester meeting or route the ASABE paper 05-5008 which provides more details. I do sincerely wish you better luck with the 2062 draper, but considering the number of hydraulics pumps and motors, you got your hands full and your moneys worth in parts. Frankly a 50 foot ClAD project header with poly floors will be less complex and more reliable and the beginning of the end for most draper headers. Respectfully, Alan VN
