I like to go shallow on hard packed soil and make successive passes going deeper as needed. Less stress that way as I see it. Deeper tines for me right off the bat is reserved for previously worked soils, ie veggie field.
Looks like you have the same problem as I did. You look to have the mushroom head pins (not flat on the side against the bar).
Note the extreme rub damage to the side of the bar by the mount from the head of the pin. When mine would do that, the bar became a splitting wedge between the mount pin and the plate, and blew the end off. I would definitely ask for warranty on that. I would suspect that you broke it by lifting, and possibly from bouncing upwards. Tolerances and how likely it was to happen is based somewhat on the thickness of the weld.
