The higher hole = higher lift. Default/standard adjustment are the highest holes.
If you want to tilt a Box Blade, use the center hole on the left. (Alternatively you can shorten adjustment on the right Lifting Rod, but that puts considerable stress on Lifting Rod adjuster threads, which can strip. )
Often with cultivating implements you need to use lowest hole on right/left to get cultivating tines into the dirt the depth you desire.
