ABSTRACT:
An improved earth working implement is disclosed which is particularly suitable for surgarcane cultivation, said implement having four main pluralities of saucer shaped cultivator discs carried by a trailer, each of said pluralities being individually adjustable to vary the angular relationship of the discs relative to the longitudinal axis of the trailer as well as the lateral spacing between the discs and said axis. A pair of retractable wheels are provided to permit the trailer to be towed between a storage area and the sugarcane fields. An adjustable soil deflector disc is disposed adjacent to and rearwardly of each plurality of discs to deflect the soil removed by the cultivator discs in a loosened condition back into the general area from which it was removed. Two additional pairs of cultivator discs are rotatably, angularly, adjustably attachable to the rear end of the trailer. In addition, an elongated beam may be transversely attached to the trailer with additional pluralities of rotatably angularly adjustable cultivator discs attached thereto to expand the one pass range of the cultivator from a normal three rows to five rows. Rakes may also be attached to the trailer and beam to remove surface debris from the immediate area of the cane rows.
