Try taking a welder and making tack welds on the auger flighting. A small portable wire welder works just fine. Start in the middle and work your way out four feet or so. The aurger is to slick and will not grab the stalks to force them into the feeder house. I have also used cloth type duct tape, putting it anywhere it will stick. A large spoke reel might help kick it onto the auger. We bought a reel at a farm sale, but never put it on. Also, we have started earlier in the morning while there is more humidity and serviced the equipment in the heat of the day. Good luck.
