Abstract: A cutting knife includes a base coupled to a head unit of an agricultural combine harvester. The cutting knife includes a blade extending away from the base. The blade includes an edge and a plurality of cutting teeth formed from the edge. The plurality of cutting teeth includes a first grouping of teeth positioned along the edge having a first pitch. The plurality of cutting teeth includes a second grouping of teeth positioned along the edge having a second pitch less than the first pitch. The first grouping of teeth is positioned closer to an end of the blade opposite the base than the second grouping of teeth.

Abstract: A roller is connected to a harvesting platform for movement with a combine over a ground surface in a direction of travel. The roller includes a first portion defining a first diameter and including a first material, and a second portion defining a second diameter and including a second material. The second diameter is greater than the first diameter. The second portion substantially surrounds the first portion, the second material has different material properties than the first material. The roller extends in the direction of travel and rotates about a second axis which extends generally parallel to the direction of travel.

Abstract: A skid plate for use with a combine harvester head unit moving in a direction of travel. The skid plate includes a body, and a contact surface at least partially defined by the body, the contact surface including a leading edge facing the direction of travel and a trailing edge opposite the leading edge, where the contact surface at least partially defines a groove, where the groove defines a groove width, and where the groove width varies as the groove extends away from the leading edge.

Abstract: A crop ramp and belt support component for an agricultural harvesting head is provided. The crop ramp and belt support component includes a forward portion, a rear portion, and a belt support portion that are generally planar. The forward portion is inclined relative to the rear portion, and the rear portion extends from the forward portion. The belt support portion is substantially parallel to the rear portion and is configured to extend at least partially below an interior surface of a belt conveyor. The forward portion, the rear portion, and the belt support portion are fabricated as a unitary component.

Abstract: A header for a combine harvester includes a center section having a first draper belt configured to move crop material in a first direction. The header also includes a wing pivotably coupled to the center section about a pivot axis and extending laterally away from the center section. The header also includes a second draper belt coupled to the wing and configured to move crop material in a second direction different than the first direction. The wing and the second draper belt are in a fixed positional relationship with each other, such that the wing is configured to remain at a constant distance from the second draper belt at all points along the wing during pivoting movement of the wing.

Abstract: An agricultural harvesting head having an elongate frame, a rear wall, side conveyors and a center conveyor. The side conveyor having an endless belt conveyor with an endless recirculating belt supported on an idler roller and a drive roller. The side conveyor is driven by an endless drive belt nested within the endless recirculating belt.
