The bobcat will follow the angle of the ground if attacking the attempted
dig 90 degrees from the angle of the slope of the soil. It also presents
a problem with possible tip over of the bobcat.

Starting at the top of the elevation, you can attack the dig with the
slope pointing the bobcat uphill. This takes alot of experience. It also
is limited in the amount of level area of each terrace. Not much. If you
can level enough area, you can use the bobcat on the level area, and
slowly work in more level area up the slope. This takes alot of
experience and patience.

The subsoil type is also a matter of concern while doing this. For
example, loose subsoil vs. stratified limestone vs. solid rock.

Subsoil is clay. I see your point.
