It is a moldboard.

Whether it will work for you or not depends on what you are wanting to do. This particular type of plow inverts the soil, and buries any residue you had on the surface. If you aren't trying to manage residue, and erosion isn't a problem, it will work fine. If you are after a clean seedbed, it should work well.

If you are trying to maintain surface residue, or erosion is a potential problem, there are other implements out there that might be better suited for the task.
