A stalk and root shredder that is provided with rollers which grasp and move stalks and roots upwardly into the path of rotation of blades which shred the stalks and roots and deposits them back onto the ground surface. The stalk and root shredder is hydraulically powered from pump units mounted directly from the tractor by connection with the power take off spline thereby eliminating the use of a power take off shaft. The hydraulic system includes separate hydraulic motors for driving the rollers and blades with the hydraulic system including a cooling arrangement which maintains optimum operating temperatures of the motor and hydraulic fluid. The stalk and root shredder includes a supporting frame and wheels with this structure being quite similar to that illustrated in my prior U.S. Pat. No. 4,015,667 issued Apr. 5, 1977 with the present invention relating to the improvements in the structure and hydraulic operation of the rollers and blade assemblies mounted over the rollers. In one embodiment, the blades rotate about vertical axis and in another embodiment the blades rotate about a transverse horizontal axis and in this embodiment, the blades and rollers are driven from the power take off of the tractor.
