I have a 2009 FD70 on a gleaner R75 and tonight I was riding in my neighbors 8230 case ih and he has a FD70 on the front of that and his header runs way way faster than mine. The side drapers run faster and the center draper and drum do. Seems to clear the cutter bar way faster than on mine cause the drapers are running so fast. Why does mine run so much slower on a gleaner?

Did you buy it new or used? Ours we had to change a sprocket cause it was previously on a lexion and now on a case. Changes ratio from pto to adapter drive. Also draper speed is adjusted by black knob sticking out of cover that has to be removed to change oil filter. Left into increase right to decrease I believe.

I had the same complaint on a 680 Deere. I took out the black knob to see how it works , its just a needle and seat assembly. The seat has 6 little holes in it , those 6 little holes are all a bit bigger now. I've only ran it for a couple of hours like this but I think it made the belts a little faster?

I put a MacDon FD70 on my 2007 JD 9660STS combine. I'm having troubles with my side canvases running slow (no mud on rollers). I've tried adjusting the knob that controls flow but no response. The center canvas speed is fine and the reel speed adjusts as it is supposed to. Will changing the filter resolve the issue or do I need to replace/check valves? Also what sproket are you refering to?
