apologize if this has been asked before just ignore if so. Tried new blades and seems like I got to just about stand on the darn thing to get a hole cut. I'm not the easiest on my auger, Bang on ice when ice on cutting head, not real hard but I suspect this was the culprit. Thinking of using 1/16 shims to put a little more angle on the cutting edge.Oh yeah yes they are on right...Thanks
