Abstract:
Soil cultivating apparatus including a frame supporting at least one rotary cutting assembly having a plurality of earth working implements spaced around a peripheral region of a rotary support member mounted for rotation about a central upright axis of rotation, each said earth working implement being downwardly depending from said support member and having a primary cutting edge extending upwardly and rearwardly from a lower soil engaging extremity thereof, said earth working implements being arranged in separate sets where the primary cutting edge of each said earth working implement of a first said set also extends outwardly relative to a circumferential line traversed by the lower soil engaging extremity of the earth working implements of said first set, and in a second said set of earth working implements, the primary cutting edge also extends radially inwardly relative to a circumferential line traversed by the lower soil engaging extremity of the primary cutting edges of the earth working implements of the second said set being located at a radial distance from the central upright axis greater than the radial distance of the lower soil engaging extremity of the primary cutting edges of the earth working implements of said first set, said central axis of rotation being tilted relative to a forward direction of movement of the soil cultivating apparatus whereby a front region of the rotary support member is always maintained at a level higher than a rear region of the rotary support member.
