While cutting wheat the last couple of years, wheat goes around back side of auger. It then flips over the top of auger where it is hit with the reel and goes to the ground. I think I finally found the problem, but looking for suggestions for the cure. Flight on auger is worn in the middle but not on the ends. so there is about 3/4 inch gap in the middle 2/3 of the platform and 1/4 inch on the outsides. Can't lower the auger because it would hit on the ends. Platform seems to be true, flighting is just shorter in middle 2/3rds of auger. Possibly buy replacement flighting??Grind flighting down on ends of auger and then lower auger?? Any suggestions?
