Abstract: A soil cultivating implement comprising a row of power-drivable, soil working members supported by a hollow frame extending substantially horizontally perpendicular to the implement's intended direct of operative travel to provide selectively upwardly or downwardly directed forces upon that row via the hollow frame. A supporting ground roller is connected behind the row, its rotary axis being contained in an imaginary vertical plane. A mobile implement provides mass to exert a downward force on the cultivating implement at a coupling point which, in turn, is translated into an upward force on the frame's forward aspect by way of arms and strong pivots, such arms being turnable about the ground roller's rotary axis. The upwardly directed force assists soil-working members automatically to elevate as needed for riding over rocks or other buried obstacles without significant damage.

Abstract: A soil preparing device for preparing forest soil to a planting bed. The device comprises a frame intended to be mounted on a forest tractor, a support arm mounted on the frame pivotally around a horizontal link, and a preparing element supported by a slide mounted vertically movably on said support arm. The slide is fastened to a hydraulic cylinder supported by said support arm for continuously adjusting the vertical position of said slide and, accordingly, of the position of the preparing element with respect to the ground during the preparation. A deviation of the support arm upwardly or downwardly from a neutral position activates said hydraulic cylinder of the slide to displace the preparing element upward and downward, respectively, due to variations in the ground level and obstacles on the ground. The preparing element can therefore be displaced clear of any unevennesses in the ground without substantially deviating from its working angle in relation to the ground.

Abstract: An implement mounts a row of rotatable members, having resilient tines, that are rotatable about upwardly extending shafts. The frame portion is pivoted to a forward coupling member at several points, a lower one of which is a shear pin that allows the frame portion to tilt upwardly about an axis defined by two upper pivots upon overload of a tined member.
