When is a good rule of thumb for changing rasp bars? I have a couple of broken/cracked bars, the ones in the front are worn down to the bolts maybe about 1/2 of bolt head still there. Rasp bars in the rear to some in the middle can still see the bolt head markings. Will maybe be doing small grains, but will be doing soybeans and corn. TIA
