ABSTRACT:
A power driven disc cultivator apparatus includes a main frame to which are connected a main sub-frame assembly and at least one second sub-frame assembly. The main sub-frame assembly mounts a shaft provided with spaced cultivator discs which are constrained to rotate with the shaft. The shaft and thus the discs are power driven at a rate independent of the speed of advance of the tractor or like vehicle towing the cultivator apparatus. The main sub-frame assembly is located at the forward end of the main frame. The second sub-frames mount shafts which are not power driven. The sub-frames can be selectively positioned lengthwise and angularly relative to the main frame.
