ABSTRACT:
An implement having an elongated tool extendable into the subsoil to break up the hardpan and open the subsoil for moisture and tap roots of plants. The tool has orbital motion generated with power driven eccentric structures coupled to the tool. Power is applied to the eccentric structure with a gear box driven with a hydraulic motor. Flywheels are connected to the eccentric structures and the gear box drive shafts. Links connected to the tool and a frame carry a rolling coulter disc operable to cut a slit in the soil ahead of the tool. A hinge assembly having elastic members mounts the frame on a carriage. In one form, the carriage is pivotally mounted on a draft beam of a moldboard plow and biased to an earthworking position by a hydraulic cylinder. In a second form, the carriage is a plate which forms a part of a hitch assembly for connecting the implement to a three-point hitch of a draft tractor.
