Abstract: A suspension system is provided for use with a crop harvesting header including a frame carrying a structure movable about an endless path to deliver a crop to the header. The frame has opposed ends and is pivotably connected to the header, each end of the frame being independently movable between a first angle between the frame and the header and a second angle between the frame and the header. A first suspension member and a second suspension member are each connected between the frame and the header to provide a substantially constant force to the frame between the first and second angles.

Abstract: An agricultural harvester is provided that Includes a frame carrying a structure movable about an endless path to deliver a crop to a header. The frame includes a guide assembly including a guide member supported by the frame. The frame also includes at least one tine secured to the guide member without extending through the guide member, and the at least one tine extending from the guide member above the structure to guide the crop between the at least one tine and the structure to the header. The at least one tine is installable and removable from the guide member without disconnecting the guide member from the frame. At least one tine is installable and removable from the guide member substantially without tools.

Abstract: A crop gathering device is provided for use with a harvesting header including a frame carrying a belt to deliver a crop to the header, the frame having opposed ends and connected to the header. The frame includes a first support member and a second support member each extending unsupported between the opposed ends of the frame. A driven roller assembly has at least two axially aligned rollers extending between the opposed ends of the frame, regions of the rollers of the driven roller assembly being rotatably secured to the first support member. An idler roller assembly has at least two axially aligned rollers extending between the opposed ends of the frame, regions of the rollers of the idler roller assembly being rotatably secured to the second support member. The roller assemblies move the belt for delivering a crop to the header.

Abstract: A spout is used for confining the grain flow from an auger. The auger may be a combine, grain cart unloading auger or a grain auger. The spout includes a chute that mounts on the auger tube. An overflow opening in the chute allows grain or other matter to flow out of the spout if the outlet of the chute is plugged. This prevents filling and overloading of the auger and consequent auger damage.

Abstract: A system for processing plant material is provided which separates plant fibers from the woody portions of the material to produce a commercially desirable length of fiber and to grind the shorter woody portions that have been separated from the longer fibers to a desirable size which has found use in certain commercial applications. The current system is well suited to process the tough fibers of the North American strain of flax straw, and will also find utility in processing other bast fibers, such as jute, hemp, ramie, and kenaf.

Abstract: A method for separating woody material from plant fibers is disclosed which includes the provision of a plurality of woody material bending regions with the plant material being fed to a first and then a second one of the bending regions as bending and pulling surfaces are moved through the bending regions. The bending and pulling surfaces move through the regions at different operating speeds so that the bending and pulling surfaces in adjacent bending regions will pull on the plant material to separate the fibers from the woody material. As the bending and pulling surfaces primarily impart a pulling or stripping force on the fiber along its length where the fiber has its most strength, the woody material can be dislodged and stripped away lengthwise with minimal damage or breakage of the fiber. The step of providing bending regions can include the step of providing first and second sets of fluted rollers having bending and pulling radially extending flute surfaces.
