ABSTRACT:
An apparatus for controlling weeds and for treating crops planted in rows has a horizontal frame connected to a transverse, horizontal tool bar of a propelling vehicle by a parallelogram linkage which is maintained in gauged vertical relation to a crop row shoulder surface by a pair of gauge wheels affixed to the frame and rolling along the shoulder surface. A pair of disc blades which may be rotatable if desired are adjustably carried along either side of the crop row shoulder by shafts mounted in the clamps on the frame, the clamps permitting vertical, lateral, and angular positioning of the shafts and disc blades. A pair of spray nozzles may be carried from the rear end of the frame for positioning on either side of the crop row for application of herbicides and other chemicals.
