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.

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.

An agricultural harvester includes a grain processing section having a crop material handling assembly. The crop material handling assembly is driven in fore and aft oscillation by a device while permitting side to side movement. A pivotal link mechanism structurally connected to the crop material handling assembly midway between its side members and to the agricultural harvester chassis drives linear side to side movement of the crop material handling assembly while permitting fore and aft movement thereof.

An agricultural vehicle includes a chassis; a threshing and separating assembly carried by the chassis; and a cleaning system carried by the chassis and configured to receive crop material that has passed through the threshing and separating assembly. The cleaning system includes a pan configured to receive crop material from the threshing and separating assembly on a pan surface and to shake in a fore-to-aft direction; at least one sieve located below the pan and configured to shake in fore-to-aft and lateral directions, the sieve including a sieve surface configured to receive crop material from the pan; and at least one divider associated with and extending at least 3 centimeters above at least one of the pan surface and the sieve surface.

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.

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.

A cleaning shoe for an agricultural machine includes a chaffer supported for movement relative to a chassis, a sieve positioned below the chaffer and supported for movement relative to the chassis. The cleaning shoe also includes a first link, a second link, and a drive shaft. The first link includes a first end and a second end coupled to the chaffer. The second link includes a first end and a second end coupled to the sieve. The drive shaft rotates about a shaft axis and includes a first cam and a second cam. The first cam is coupled to the first end of the first link, and the second cam is coupled to the first end of the second link. Rotation of the drive shaft drives the first link to reciprocate the chaffer and drives the second link to reciprocate the sieve. The second cam is angularly offset relative to the first cam by a phase angle less than 180 degrees about the shaft axis.

A harvesting device, in particular, for harvesting cereals, rice, grains or seeds, has a crop stripper with a nose hood for determining a working width, an inclined chute, a threshing device, a separation device, a cleaning-air channel, and preferably a cleaning device, a bulk material conveyor and/or a cutting and/or crushing device.
