Abstract: An agricultural harvester has a chassis carrying a header removably attached to a feeder housing for gathering a type of crop and feeding it into the agricultural harvester. The feeder housing is connected to a threshing and separating system for separating grain from MOG, which leads to a grain cleaning system for cleaning the separated grain. The grain cleaning system has at least one sieve operable to oscillate fore and aft, and at least one cleaning fan. The grain cleaning system also has a side shaker mechanism operable to produce a side to side shaking motion. A control system is connected to the side shaker mechanism and is operable to automatically adjust the amount of side to side shaking motion on the basis of the type of crop and on the basis of the amount of side slope upon which the agricultural harvester is situated.

Abstract: An agricultural harvester has a chassis carrying a header for gathering a crop. The header is removably attached to a feeder housing for feeding the crop into the agricultural harvester to be processed. A threshing and separating system is connected to the feeder housing for separating grain from Material Other than Grain (MOG). A grain cleaning system is connected to the threshing and separating system for further cleaning the separated grain. The grain cleaning system has at least one sieve operable to oscillate fore and aft and a side shaker mechanism operable to produce a side to side shaking motion in the at least one sieve. A control system is connected to the side shaker mechanism and operable to automatically proportionately increase an amount of the side to side shaking motion as a function of an amount and type of crop being processed.

Abstract: A sieve arrangement for an agricultural combine harvester includes a sieve frame for carrying a sieve, a side shaker arm, and a plurality of elongate structural members. The sieve frame includes a first side frame member and a second side frame member. The side shaker arm is connected with the first side frame member. Each structural member has a first end connected to the side shaker arm, and a second end connected with the second side frame member.

Abstract: An agricultural harvester includes a grain processing section having a sieve assembly. The sieve assembly is connected to mechanism for producing a side to side oscillation by a single cast structural link having an input through slotted openings to the drive mechanism to accommodate misalignment. The link has vertical and horizontal flanges connected to a main body for interconnection between the right and left frames and structural supports interconnecting the right and left frames. The main body of the link extends through a slot in a rubber wall to accommodate the movement and seal against loss of grain.

Abstract: An agricultural harvester includes a grain processing section having a sieve. The sieve is driven in fore and aft oscillation while permitting side to side movement by a pair of cast members interconnected each having three mounting points. Two of the mounting points of the members are interconnected by flexible rubber bushings and the third mounting point of one of the members receives fore and aft oscillating movement and the third mounting point on the second of the members pivotally interconnects to the sieve to drive it into fore and aft oscillation while permitting side to side movement.

Abstract: An agricultural harvester includes a grain processing section having a sieve assembly. The sieve assembly includes right and left frames interconnected by a cross member. The cross member has end castings securable to the right and left frame members. An elongated U-shaped sheet metal member extends between the castings. An elongated slot at each of the U-shaped sheet metal member terminates in a circular hole. The slot and circular hole accommodate variations in forming tolerances for the U-shaped sheet member and dissipate stresses.

Abstract: A cleaning system for an agricultural combine harvester includes a sieve having a periphery and an interference member located at the periphery. A chaffer frame carries the sieve, and includes a clamp with a pair of spring fingers positioned on either side of the interference member, thereby retaining the sieve within the chaffer frame.

Abstract: A spreader arrangement for an agricultural harvester includes a frame, a pair of spreader discs carried by the frame, and a material deflector. The spreader discs are generally horizontally arranged and rotatable in a counter rotating manner. The material deflector includes at least one deflector arm and a vertical pivoting mechanism interconnecting the at least one deflector arm with the frame.

Abstract: An agricultural harvester with a crop processing apparatus. The crop processing apparatus is configured for separating crop material from crop residue and for discharging crop residue therefrom. The agricultural harvester includes a duct for directing a stream of crop residue downstream in the agricultural combine in a generally downward direction, a pair of laterally spaced spreader devices positioned downstream of and below the crop residue duct for distributing crop residue laterally, and deflectors spaced outwardly of the spreader devices and oriented generally in a vertical plane. The deflectors are mounted at a first upstream edge relative to the flow of the crop residue stream and extend downstream. The deflectors have an upper edge curved toward the spreader devices to an increasing extent away from the upstream edge.
