After reaching the set digging depth (a), keep digging while maintaining the digging depth (a) against the current
surface.

The digging depth becomes shallow promptly before the load on the blade becomes excessive and the machine
can not travel forward. Travel the machine to the piling position (U) since the carrying operation will be per-
formed later along the current surface.
