2 weeks later: In preparation for adding MagCl I worked the footing again. This time I did use the profile blade. It was again a bit of a difficult pull the first time around. I think I was cutting off the ridges left by my first resuscitation working with the ripping teeth.Second time around it pulled just fine. The footing was very soft and smooth. I do think I can and will use the profile blade for subsequent workings and reserve the ripping teeth for repair if ever the need (or perhaps my drive). I am very pleased with this purchase. Please note the wheels are really only for transport. The rake on the back is truly the depth gauge.
