I Google'd the name and looked at pictures of those attachments.
It is a box-blade that has ripper teeth attached to the back. If you rotate the box, the ripper teeth are in the down position. Your picture shows the unit with the ripper teeth down and the box side plates pointing up. If you rotate it to the other position, it will put the cutting edge down and the side plates in the normal operating position.
Box-blades are used to level the soil by cutting off the high areas and pulling the soil along in the box. If you cross over a low area, that soil drops in to the low areas. The ripper is used to break up compacted soil so it is easier for the cutting edge to penetrate into the grade.
The way it is mounted, you will use it by driving in reverse. Most skid steer box blades are mounted so you operate them driving forward.
