Cutting Edge for 9" Butterfly Style Auger

My homestead is full of red and yellow clay. I have nearly as much quartz as I do clay! When your auger stops digging well change these and look at your tip. I had to get the tip directly from king kutter. The outter corner of the chisel end wears like a J. To break the bolts free I had to weld a 5/16 Allen wrench to the head of the bolt. Just using an allen key ended up rounding both the key and the bolt. Weld a cheap Allen and presto. Took me hours to figure this out. Wish I could attach pics to show difference between old and new cutting edges and how I welded but agri supply review doesn't let me attach image.

Please note, this tip is sold at Agri Supply
