Traveling rolling digger for sequential hole drilling and for producing sequential cultivated spots in soil

A traveling rolling digger for sequential hole drilling or for producing sequential cultivated spots in soil, the traveling rolling digger comprising:

• at least one drilling shaft which is rotatable by a drive mechanism about a longitudinal shaft axis and having a rotating soil penetrating edge;
• said at least one drilling shaft being mounted to roll about a horizontal shaft in a soil penetrating plane while said horizontal shaft moves in a direction of travel of the traveling rolling digger, whereby said at least one rotating drilling shaft enters the soil at an entry angle and digs into the soil while the horizontal shaft moves in said direction of travel and the drilling shaft continuously changes its angle relative to the soil from the entry angle to a vertical position;
• and
• at least one following soil penetrating and lifting shank, said lifting shank being mounted to roll about said horizontal shaft, said lifting shank having a soil penetrating edge positioned to enter the soil shortly before or when said drilling shaft reaches a maximum depth at its vertical position and said lifting shank acts as a pivot to lift the drilling shaft while the traveling rolling digger moves in said direction of travel;
• and
• said horizontal shaft being mounted on a support structure which is adapted to be connected to or mounted on a self propelled vehicle.
