i posted on this earlier but forgot the hardest one to repair.
sometimes the auger bucket is actually twisted and it wont line up quite right.and no amount of fiddling will fix it.
you have to set it on a very flat surface and do some carefull measuring everywher there is a bolt hole the same from side to side.i use the holes for the driftcutters.
only saw one that was built out of line and it was welded wrong
came from sears.dont remember if it was mtd ayp or murry built.
