ABSTRACT:
An implement has one or more rows of tines fixed to frame beams and the lateral sides of the frame have adjustable ground wheels to control the working depths of the tines. A further soil working member is connected at the rear of the frame by parallelogram linkages and a driven eccentric on the further member imparts up and down vibratory movements to that member. Each linkage includes a bracket, the lower front portion of which is pivoted to a rear frame beam and rearwardly extending arms that are pivoted to vertical support arms that carry and move the further member. Above the pivot connection to the frame, the bracket has connection points for a tie arm that extends forward to a leading frame beam. A fixing mechanism interconnects the upper linkage arm with the front of the bracket at two spaced apart locations and springs in the mechanism bias the arm and further member to an equilibrium position. The angularity of the linkages can be changed with the bracket connections to the tie arms and/or mechanism. The further member includes transverse rods that define a convex ground-engaging surface.
