In a soil cultivating implement of the kind which comprises a row of rotary power driven soil working members 3, having tines 4, that is carried by a hollow elongate frame portion 1 that extends substantially horizontally perpendicular, or at least transverse, to the intended direction of operative travel A of the implement, screens 14 are arranged adjacent the opposite ends of the row of members 3 to co-operate with the nearest members 3 in cultivating the soil, said screens 14 taking the form of preferably resilient elongate elements 17 at least parts of which are non-horizontally disposed when the implement is in use. Advantageously, a carrier 15 of each screen 14 is connected to the hollow frame portion 1 so as to be upwardly and downwardly displaceable through the intermediary of an irregular quadrilateral linkage 16 comprising substantially horizontal pivots 11 and 13. <IMAGE> |
