ABSTRACT:
Two embodiments, a towed embodiment and a self-propelled embodiment, of a compost machine for shredding, mixing and aerating decomposable and non-decomposable waste material deposited in strips on large sites are disclosed. Both embodiments of the compost machine of this invention include a frame-suspension member, a rotary member, a plurality of replaceable teeth carried by the rotary member, a folding protective shield system, a pair of hydraulic motors and a prime mover. In both embodiments the hydraulic motors are mounted inside the rotary member, one at each end and are driven by the prime mover through a shock-protective coupling arrangement. In addition to the aforementioned common structural elements, the towed embodiment of the compost machine includes a foldable tow-bar assembly and a pair of tired wheels, one mounted on each side of the frame; and the self-propelled embodiment of the compost machine includes in addition to the aforementioned common structural elements a pair of tracks, one mounted on each side of the frame, a conventional crawler undercarriage, a suspension propel system, a foldable operator cab and the controls. The towed embodiment of the compost machine of this invention can be readily loaded and transported, without disassembly, from site to site, on a conventional truck-trailer due to the fact that the tow bar assembly and the shields of the protective shield system are foldable and the wheels are vertically adjustable such that the wheels can be extended to raise the compost machine for loading and retracted above the bottom of the frame skids to secure the compost machine during transport. Similarly, the self-propelled embodiment can be readily loaded and transported without disassembly, from site to site on a conventional truck-trailer due to the fact that the shields of the protective shield system and the cab are foldable and the crawler units are vertically adjustable such that the crawler units can be extended to raise the compost machine for loading and retracted above the bottom of the frame skids to secure the compost machine during transport.
