ABSTRACT:
A cultivating implement has an elongated frame portion that mounts a row of rotors that rotate about upwardly extending axes. At the lateral sides of the frame portion, screening plates are positioned to arrest the lateral displacement of soil being worked. Each screen is substantially vertical with its front part being linked to an overlying frame structure and rear roller that supports the frame portion. Parallelogram links arranged one above the other interconnect each plate with a support part of the structure. The links extend forwardly from the plate from pivot connections to further pivot connections. The connections define horizontal transverse axes that allow the plate to move up and down as it rides along the ground. The front connections are resilient members that allow some lateral deflection of the plate. The plate has an upper, rear bent over portion that allows entry of a supporting roller arm to a pivot connection to the supporting frame structure. A lower bent portion of the plate forms a guide for the soil.
