ABSTRACT:
A cultivator has a row of soil working members journalled in an elongated frame portion. The frame portion is supported on side-by-side elongated elements that extend generally parallel to the direction of travel. The elements are preferrably curved and can be arranged in a forward group attached at the front of frame portion and a rear group of different-shaped elements that are interconnected to the frame portion to bear on the ground at the rear of the soil working members. The rear group can be fastened to a central carrier and curved to form a supporting roller. The elements can be inherently resilient and/or interconnected with spring mechanisms so that the soil working members respond to ground undulations.
