ABSTRACT:
A cultivator has driven soil working members mounted on corresponding upwardly extending shafts and each member includes a support with a hub secured near the lower end of a respective shaft. The support is formed from flat sheet material which define resilient arms that extend outwardly from the hub. Preferrably, the arms include two spaced apart parallel strips with a holder near the outer ends of the two strips. Fasteners, such as bolts, clamp the arms together and the strips of neighboring arms can be integral with one another. The arms and corresponding tines are thus deflectable in directions perpendicular to the planes of the strips.
