Do your self a favor and trash the wheel then go buy a walker for the end of the sweep auger. It bolts on to the end of the auger just like the wheel. Has two irons that osolate foward and back to move the auger foward. They are ajustable to run the auger closer or away from the floor. When you get to then last of the corn, it will not go a 100 mph around the floor till you turn the auger off. Once they are ajusted right and you may have to relocate some screws that will stop the walker, you will never have to push the sweep around the bin again.
