A sieve for a cleaning system of an agricultural harvester includes: a sieve frame defining a top side; adjustable louvers carried by the sieve frame and defining apertures; an adjustment bar coupled to the adjustable louvers such that displacement of the adjustment bar changes a size of at least some of the apertures; and an adjustment assembly. The adjustment assembly includes: an adjustment arm coupled to the adjustment bar and pivotable relative to the sieve frame such that pivoting of the adjustment arm about a pivot axis displaces the adjustment bar. The adjustment arm carries a locking pin. A shaft is disposed on the top side and coupled to the adjustment arm. Displacement of the shaft from a first position to a second position causes a corresponding displacement of the locking pin from a locking position to an adjustment position.

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.

Linkage for agricultural harvester cleaner

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.

Side shaker link for agricultural harvester sieve assembly

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.

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.

Sieve arrangements for a cleaning system in an agricultural harvester

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 tag axle assembly for an agricultural machine, such as a harvester, and method for redistributing weight of the harvester from the rear axle of the harvester when a header is removed, or when replaced by a lighter header, at the front of the harvester. The tag axle assembly includes a tag axle with tires that may be lowered so that the tires contact the ground when no header is attached to the machine to absorb loads transferred from the front of the harvester to the rear axle and rear tires at the rear of the harvester. The tag axle and tires may be raised up from the ground, or the tag axle assembly may be removed from the harvester, when a header is attached to the front of the harvester causing redistribution of load from off the rear axle and rear tires.

Additional axle for agricultural machine weight redistribution

A cleaning system for an agriculture work vehicle including a combination of a grain cleaning sieve having a limited region containing larger apertures providing increased grain throughput and also increased air throughput relative to the other regions of the sieve, utilized with a fan system that provides a substantially higher air flow rate through the region relative to the other regions of the sieve, such that a downward airborne flow of crop material above and flowing toward the limited region is subject to an air flow having a substantially higher flow rate compared to the other regions above the sieve, which operates to aggressively separate material other than grain from the grain above the limited region, and such that substantially only grain will fall onto and pass through the limited region of the grain cleaning sieve.
