<p>An integrated shredder/plow combination for reducing trash to facilitate its being mixed with the soil by the action of the trailing plow portion of the combination is disclosed. The shredder portion includes a unique arched structure positioned above a housing enclosing the shredder's cutting blades which permits the plow's drag to be transmitted directly to the tractor hitch so as to bypass the shredder assembly. The shredder assembly is thus not subjected to the large longitudinal forces associated with plowing operations as well as the high side loading encountered during turns and as a result of ground contour. This prolongs shredder operating lifetime and increases its reliability. By positioning the plow assembly immediately aft of the shredder mechanism, the cut-up vegetation, or trash, is more effectively turned under as it is in an agitated, suspended condition when it encounters the burying action of the trailing plow assemblies. The shredder/plow combination includes tractor-operated hydraulic cylinders in combination with transport wheels to facilitate transport of the shredder/plow combination to and from the work area. The shredder portion is driven by a power supply shaft prom the tractor via a gear box and includes drive belt tension adjustment means for selecting the rotational drive force applied to the shredder's rotor. In addition, the shredder portion may be detached from the plow portion of the combination and easily installed between a tractor hitch and a conventional tool bar assembly.</p> |
