ABSTRACT:
A soil cultivating implement has a row of working rotors which are supported by a plurality of elongate, resilient rod-like elements that are arranged to afford a grating immediately to the rear of the rotors. The elments are C-shaped with their convex sides extending in the direction of travel, horizontal lower portions that ride on the ground and upper fastening portions, including coils, that are secured to a beam support. The support, together with elements, are interconnected to the frame via pivoted arms that can be vertically adjusted to change the working depths of the rotors. The elements are positioned at varying distances behind the rotors so that their foremost parts define an imaginary sinusoidal line, when viewed in plan.
