Abstract of the Disclosure 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 hori- zontal 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.
