ABSTRACT:
A soil cultivating implement has an elongated hollow frame portion that houses an eccentric drive transmission to a row of soil working members mounted on respective upwardly extending shafts journalled on the frame portion. The eccentric drive includes two eccentric discs that are mounted out-of-phase on an upwardly extending driving shaft. The eccentrics are pivoted to radial arms on the member shafts of different alternate soil working members by connecting rods so that adjacent members are oscillated in relatively opposite directions. The shafts are located in a plane that is substantially parallel to the longitudinal center line of the frame portion and to the rear of that line and the rods. Each member has three radial arm supports with respective tines, two of the arms being shorter than a third. It is preferred that the longer arm support of alternate members extend rearwardly in the center of its oscillating path and opposite to the direction of the arm supports of adjacent members. The tines are positioned to work overlapping strips of ground.
