ABSTRACT:
A cultivator has an elongated frame and a plurality of rotary soil working members mounted side-by-side in a row that extends transverse to the direction of travel. The soil working members have depending tines that rotate about upwardly extending shafts which are connected to horizontal supports for the tines. A screening element extends along the front of the frame and is displaceable relative to the frame via a pivoted arm and spring arrangement that biases the element to a position closely adjacent to the connections between the tines and their supports. The elements are connected to arms that are jack-knifed and pivoted to turn about an axis located above the frame. A rotary soil compressing member may be attached to the rear of the frame.
