Soil cultivating implements

A soil cultivating implement comprising a frame and a transverse row of soil working members rotatably mounted on respective stub shafts that define upwardly extending axes, each soil working member having downwardly extending tines positioned around its axis of rotation and being freely rotatable about its corresponding axis responsive to the contact of its tines with the ground, said soil working members being releaseably fastened with respective brackets on an elongated beam that extends transverse to the direction of travel, the stub shafts of said soil working members being held in said brackets, said brackets being positioned directly below said beam and being obliquely inclined to the vertical, said shafts being substantially parallel to one another and located in a transverse plane that extends substantially perpendicular to the normal direction of implement travel, each of said brackets being channel shaped with a base positioned between limbs, said limbs having dissimilar vertical lengths and said base being inclined to the horizontal, a respective stub shaft being journalled in said base, said tines each having a substantially straight soil working portion that in the lowest position of the tine, extends obliquely forwardly with respect to the front of the machine, a ground engaging roller being positioned to the rear of said row of soil working members and said roller being connected to the frame and supporting same, said roller extending at least partly across the working width of the implement, the axis of rotation of said roller extending substantially horizontal and parallel to said plane.
