A drop pan system for collecting a sample of crop material discharged by a harvester while harvesting crops. The drop pan is magnetically coupled to a support structure disposed on the harvester by at least one electro-permanent magnet having a default de-energized state and an energized state. In the default de-energized state, the at least one electro-permanent magnet is electrically isolated from an electric power source. In the energized state, the least one electro-permanent magnet is electrically coupled with the electric power source. As the harvester advances through the field harvesting the crop, the drop pan is released from the support structure by switching the electro-permanent magnet from the default de-energized state to the energized state such that the drop pan drops to the ground surface. The open top end of the drop pan on the ground surface captures a sample of the crop material discharged by the advancing harvester.

A combine harvester including a cleaning shoe, having a tailings auger for collection of tailings, a tailings collection bin and apparatus for moving material from the tailings auger to the tailings collection bin.

A drop pan system for collecting discharge samples from combine harvesters or other conveyed machines or implements features a support housing attachable to the machine, a drop pan receivable in a nested position within the housing, and a magnetic hold/release mechanism with electro-permanent magnets responsive to selective energization to switch from a holding state emitting an external magnetic field for holding the drop pan in the nested position, to a release state cancelling the external magnetic field to thereby release the drop pan from the housing. A power supply is positioned on the housing at an area that resides within a footprint of the drop pan's nested position. Differently sized drop pans may be included, and the housing may include alignment guides for self-aligning the drop pan during magnetically aided placement thereof. Electrical components of the housing may be contained in an enclosure that doubles as a support for the electro-permanent magnets.

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.

A separating and cleaning mechanism for an agricultural combine may include: a return pan. The return pan includes a textured floor, two augers, and two motors coupled to the two augers, respectively, to selectively drive the motors in rotation independently. The textured floor may oscillate in a fore-and-aft direction to move grain toward the two augers.
