Marengo, Ia.
I was told by Helmuth Repair that when they're flat on the bottom (normally have a "frown" on the bottom) they need to be replaced. You'll also run out of adjustment on the bottom pan.
Otherwise, keep replacing the bushings and bolts.
Helmuth is probably one of the bigger Kuhn-Knight dealers in eastern iowa.
