ABSTRACT:
A root and stalk shredder having a frame, a pair of longitudinally extending, parallel, power driven lifting rollers rotatably mounted on the frame and extending longitudinally parallel to a path of travel of the shredder, guide means mounted on the frame forward of the rollers in the direction of movement of the shredder for guiding stalks between the rollers, a blade assembly mounted on the frame over the rollers and operatively associated with the rollers for cutting roots and stalks lifted by the rollers, and a plow assembly mounted on the frame and provided with a fin assembly for facilitating use of the shredder to re-shape a bed being cleared. A bed re-shaping assembly is mounted at the rear end of the shredder frame for covering over shredded crop residue deflected down into the bed by a deflector shield also arranged at the rear of the shredder frame. Advantageously, a disc blade assembly is arranged at the front of the shredder frame for clearing a pathway for the plow assembly through heavy weeds, debris, and the like. The blade assembly may comprise two overlapping sets of vertically spaced blade clusters, while the lifter rollers are advantageously provided with resilient sleeves on cylindrical portions of the rollers rearward in the shredder frame. These resilient sleeves are constructed so as to form a plurality of longitudinally extending ribs which may be reinforced by rods, and the like, so as to prolong the life of the sleeves. Generally Y-shaped handles associated with wheel assemblies which movably support the frame of the shredder facilitate adjustment of the wheel assemblies in order to obtain proper leveling of the shredder frame relative to a surface being worked. In a modified embodiment of the shredder, the blade clusters may be arranged for rotation about a horizontal axis as opposed to parallel vertical axes in order to obtain finer shredding of the crop residue and to achieve adaptability of the shredder to crop beds having different row spacings.
