ABSTRACT:
A duplicate shield mechanism or unit is employed for each rearmost sweep of a cultivator. The unit in each instance includes two laterally adjustable disks mounted for rotation at the trailing end of a longitudinally adjustable two-piece drawbar or arm. The forward end of each drawbar or arm is pivotally attached to a selected portion of the rear shank having the sweep with which the unit is to co-act. Both disks of each unit travel between the rows of plants rather than over the row.
