Hi, could use some help trying to figure out a chatter in the reel pump drive on '05 2388 combine. When we start the header the hydraulic system chatters. By slowing down and speeding up the reel pump control , the symptom goes away. I have tried bypassing couplers with header disconnected, so its not the couplers or the header. Would sure appreciate help.
