ABSTRACT:
A cultivating machine includes a forward row of subsoil tools and a pair of elongated cultivating rollers having support plates to which soil penetrating T-section bars or knife edged bars are attached. To the rear of the cultivating rollers, a trailing supporting roller is journalled on the frame and adjusting arms to the roller can be interconnected with the frame to raise or lower same and thereby set the soil working levels of the subsoil. Each cultivating roller can have its soil penetrating depth controlled through pivot arm connections that move the roller through an arc centered on the pivot axes which extend transverse to the direction of machine travel. The cultivating rollers can be moved towards or away from one another. The machine frame has a coupling that is connectable to the lifting hitch of a tractor and tanks of liquid soil treating material are at least partly supported by frame connections to the tractor, adjacent the coupling. Spraying booms between the rollers and at the rear of the tools are in communication with the tanks and seed drills at the rear of the rollers enable cultivation, soil treatment and planting to be done in one pass. The cultivating rollers ensure that the material sprayed is thoroughly mixed with worked soil and vegetation cut by the rollers.
