Abstract:

A cultivator particularly well adapted for use in vineyards and orchards because of its ability to cultivate the ground between successive plants in the same row includes a main frame that is continuously laterally expandable under control of the operator to accommodate variations in the spacing between rows; outriggers that flank the main frame and that contract laterally when collision with an object in their path becomes imminent; a spot sprayer mounted on each outrigger and activated by the lateral contraction and expansion of the outrigger to direct a spray of herbicide or other chemicals at the base of each plant but no where else; and a cultivator shank assembly that is castered-mounted to the outrigger or to the main frame so as to pivot to assume the direction of motion of the outrigger or main frame to which it is mounted.
