ABSTRACT:
A cultivator has a row of soil working members or rotors mounted on axis shafts journalled on a frame portion. Each rotor has a single rotatable downwardly extending tine that is offset with respect to its axis shaft of rotation to work a diameter that is less than the spacing between adjacent axis shafts. Thus, unworked strips of soil are left between worked strips after the cultivator has traveled. A mechanism for depositing material is located to the rear of the soil working members and the mechanism includes delivery devices mounted on a common support that is linked to the frame portion by respective parallelogram linkages. The delivery devices can be drills positioned in line with the soil working members to deposit material selectively in the worked strips. Rear wheels can be attached to each linkage at the rear thereof so that each drill follows ground undulations.
