ABSTRACT:
The apparatuses comprise a horizontally extending rigid frame and a plurality of reel and shaft assemblies, those reel and shaft assemblies each comprising a pair of parallel axle shafts and a set of reels rotatably supported on each of said shafts; the peripheral edges of ground engaging blades on a first set of rotatable reels meet the ground in the treated path at a first angle to or parallel to the central longitudinal axis of a first shaft on the frame and the peripheral edges of the ground engaging blades on a second set of rotatable reels meet the ground to form cuts therein at an angle to the line of the edge of the blades of the first set of reels. The apparatus serves to form a first series of cuts extending transversely to the path of the apparatus between row crops and a second series of cuts at an angle to the first series of cuts; accordingly, such apparatuses arrange the earth originally in those paths into relatively uniformly sized particulate porous masses and maintain the biological activity of the bacteria content in the soil.
The field of art to which this invention pertains is laterally spaced rolling cultivators.
