Abstract
A traveling rolling digger for sequential hole drilling or for producing sequential cultivated spots in soil. The traveling rolling digger includes at least one drilling shaft which is rotatable by a drive mechanism about a longitudinal shaft axis and has a rotating soil penetrating edge. The drilling shaft is mounted to roll about a horizontal shaft in a soil penetrating plane while the horizontal shaft moves in a direction of travel of the traveling rolling digger. The rotating drilling shaft enters the soil at an entry angle and digs into the soil while the horizontal shaft moves in the direction of travel and the drilling shaft continuously changes its angle relative to the soil from the entry angle to a vertical position. The traveling rolling digger further has at least one following soil penetrating and lifting shank, The lifting shank is mounted to roll about said horizontal shaft and has a soil penetrating end 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 the direction of travel.
