I have a 10.9 and for some reason my rotors will just slow down and “plug” but the combine isn’t plugged I can go and pull the canola through by hand with the slug wrench. If I try to start the thresher a warning saying the threshing cl gearbox temp is too hot. So I’m guessing that that clutch is slipping and getting hot. I don’t know why. When I started the canola I had the rotors in high speed at 1000rpm but I was ripping the coating off so I slowed them down to 800rpm. Then this plugging would happen. So I switched the rotors to low gear and running them at 700rpm (max) and it still plugs. I have the dsp drum (front drum/ accelerator) in low speed. The mechanics in town think I’m peeling the canola because there’s not enough in the rotors so put the dsp in high speed and run the rotors at 1000rpm. So I’m going to try that but I have my doubts. Does anyone know why that oil would be getting so hot causing that clutch to slip?
