Abstract: A windrower with a header has a conveying medium with first and second portions connected with a pivot joint and moveable across a plural rollers configured to receive crop material from the header and direct the crop material to a side of the windrower to form a windrow on the ground to the side of the windrower. In an operational position and with the frame selected to one of the predetermined angular adjustments, the conveying medium discharges the harvested crop material at an angle of trajectory determined by the selected angular position of the second portion. The windrower harvests crop with the header, receives the mowed crop on the conveyor system, adjusts a rate at which the mowed crop is discharged from the conveyor system, and adjusts an angle of trajectory at which the mowed crop is discharged from the conveyor system.

Abstract: A high strength sieve which is lightweight and durable without having to add springs, and without requiring a high level of force to effect adjustment of the louvers. The high strength sieve utilizes hollow tubes to support the louvers. Providing hollow tubes (i.e., rather than solid wires) allows for larger diameter holes to be used in the frame. This provides for increased bearing surfaces, as well as provides for better tolerances. This reduces the movement of the tubes within the holes. Preferably, the tubes are mounted in the frame through holes which are extruded, thereby providing for increased bearing surfaces and a tighter fit. The extruded holes also provide a natural lead-in for the insertion of the tubes (i.e., during assembly of the sieve). Alternatively, solid wires can be provided extending through the extruded holes instead of hollow tubes.

Abstract: A draper header for a harvester useful for providing hydraulic lifting and lowering of ground wheels. Hydraulic cylinders are capable of being actuated to independently lower and raise the ground wheels of the header while using the floatation pressure from the lift cylinders of the harvester. First and second hydraulic cylinders are fluidically coupled to a charge pressure of the harvester, the charge pressure providing a floatation pressure to position first and second ground wheels at a lowered operation mode and a raised operation mode.

Abstract: A sieve assembly for use within an agricultural harvester may generally include a sieve, a crop material sheet, and at least one support element. The sieve extends along a length defined between a first sieve end and a second sieve end and processes a flow of harvested crop material.

The crop material sheet extends along a length defined between a first sheet end and a second sheet end and receives the cleaned crop material directed through the sieve's openings. The crop material sheet then directs the flow of cleaned crop material towards a separate component of the crop processing system. In addition, the support element(s) is directly coupled between the sieve and the crop material sheet and structurally connects the sieve to the crop material sheet.

Abstract: A control arm linkage system includes a pair of upper control arms and a pair of lower control arms to attach a crop harvesting header to a harvester frame of an agricultural harvester. The attachment of the header to the harvester via the control arm linkage system allows the header to move relative the harvester, with the header being displaced upward and heeled backwards in response to an upward force being imparted onto a lower surface of the header. The control arm linkage system thus allows the header to automatically adjust and adapt to unexpected raised mound that may be encountered along the path of the header during harvesting.
