Abstract (en)
When erecting a post or pillar (1) in a hole (2) which is to be refilled after erection, it is desirable to flatten or compress the filling (3) so that the post or pillar (1) will stand firmly. This is done in accordance with the invention by locating a transversely running elongate body (10) at the free end of the arm system (4) on a ground-preparing machine, the free end of the body being suitably shaped for flattening, the flattening process being performed when the arm system (4) forces the free end of the elongate arm (10) against said filling.
