I've had an issue ever since I've owned my Gleaner K, the raddle chain slip clutch will slip and I can never find anything that is stuck or in a bind. Usually cutting the thrasher off and back on will clear the jam and i can go back to picking. The jaws are in really good shape, last fall it did it, never could find the cause so I removed the nut and spring, then added a washer, picked good until today and it slipped with 4 rows to go. I checked everywhere, removed the front cover, the side panels, could not see anything so I had to leave the 4 rows and took it back to the farm. Do you think I need to add one more washer? Or does anyone know a trick to get the jam cleared out and back going? Its aggravating more than anything, esp when you are miles down the road.
