NOVELTY - Composting whole object, comprises: (A1) (a) providing housing having composting chamber; (b) providing grinder supported in composting chamber; (c) providing mixing member supported in composting chamber; (d) providing grinder with first grinding element and second grinding element rotatable relative to one another; (e) inserting whole object into composting chamber; (f) grinding whole object into ground material by rotating first edges of first grinding element in close proximity past the second edges of second grinding element; and (g) mixing ground material in composting chamber.    USE - The method is useful for composting whole object.    ADVANTAGE - The method utilizes composter device, which permits preparing and decomposing compost matter within a single chamber, thus requiring minimal handling or involvement on the part of a user of the composter device.    DETAILED DESCRIPTION - Composting a whole object, comprises either: (A1) (a) providing a housing having a composting chamber arranged to receive the whole object in it, (b) providing a grinder supported in the composting chamber at the bottom end of the composting chamber, (c) providing a mixing member supported in the composting chamber above the grinder for rotation about an upright axis relative to the housing, where the mixing member is open and unobstructed along the upright axis member in the form of a sweep arm which spirals upwardly in a direction sloping away from a direction of rotation of the sweep arm from a bottom end of the sweep arm adjacent the grinder at the bottom end of the chamber to a top end of the sweep arm spaced above the grinder at the bottom end of the chamber such that the sweep arm is in proximity to a wall of the composting chamber throughout a full length of the sweep arm between the bottom end and the top end of the sweep arm, (d) providing the grinder with a first grinding element and a second grinding element rotatable relative to one another about the upright axis of the mixing member, where the first grinding element comprises a rigid member including a slot formed in it which extends fully through the rigid member from a first side to a second side of the rigid member and defining first edges at a periphery of the slot, and the second grinding element comprises a lug defining second edges which closely fits within the slot and which is arranged to pass fully through the slot from the first side to the second side of the rigid member as the grinding elements are rotated relative to one another, (e) inserting the whole object into the composting chamber along the unobstructed upright axis of the mixing member to the grinder at the bottom end of the composting chamber, (f) grinding the whole object into a ground material at the bottom end of the composting chamber by rotating the first edges of the first grinding element in close proximity past the second edges of the second grinding element so as to produce a shearing action between the first and second edges, and (g) mixing the ground material in the composting chamber by rotating the mixing member such that the sweep arm moves about the composting chamber in a sweeping motion adjacent to the wall of the composting chamber to urge the ground material from the grinder at the bottom end of the composting chamber upwardly along the wall of the composting chamber; or (A2) (a) as above per se, (b1) providing a grinder supported in the composting chamber at the bottom end of the composting chamber, where the grinder includes a first grinding element having first edges and a second grinding element having second edges such that the first and second edges are rotatable relative to one another in close proximity past one another so as to produce a shearing action between the first and second edges, (c1) providing a mixing member supported in the composting chamber above the grinder for rotation about an upright axis relative to the housing and including a drive shaft extending through the bottom end of the composting chamber for rotation relative to the housing of the composting chamber with the mixer about the upright axis, (d1) providing a gearbox having a gearbox housing and a gearbox output shaft supported for rotation relative to the gearbox housing by respective gearbox bearings, (e1) providing a motor coupled to the gearbox so as to drive rotation of the gearbox output shaft, (f1) supporting the gearbox housing in an axial direction of the drive shaft solely by connection of the gearbox output shaft to the drive shaft of the mixing member such that the gearbox housing is suspended below the composting chamber on the drive shaft extending through the bottom end of the composting chamber, and (g1) supporting the gearbox housing to resist rotation of the gearbox housing relative to the housing of the composting chamber about the upright axis of the mixing member by providing at least one torque member coupled between the gearbox housing and the housing of the composting chamber such that the torque member only provides support to the gearbox housing against rotation of the gearbox housing about the upright axis relative to the housing of the composting chamber.
